Carbon Filters for Water: The Complete Guide
Carbon filtration is the most widely used water treatment technology in the world, and for good reason: it removes chlorine, bad taste and odor, volatile organic compounds (VOCs), and many chemicals that other filter types miss entirely. After 32 years installing water treatment systems, I can tell you that a properly sized whole house carbon filter is one of the smartest investments a homeowner can make — see our complete whole house water filter guide. This guide covers everything you need to know: what carbon removes, how it works, the different types, how to size one for your home, and what carbon filters cannot do.
If you plan to install the carbon filter yourself, our complete DIY installation guide covers every system type including carbon filters.
The Short Version
Carbon filters use a process called adsorption to trap contaminants as water passes through activated carbon media. They are the standard treatment for chlorine, taste and odor issues, VOCs, and certain chemicals. Here's what you need to know:
- What carbon removes: Chlorine, chloramines (with catalytic carbon), VOCs, THMs, pesticides, herbicides, hydrogen sulfide (rotten egg smell), radon, and bad taste/odor. Browse our full selection of whole house carbon filters.
- What carbon does NOT remove: Hardness minerals, iron, bacteria, nitrates, fluoride, or total dissolved solids (TDS). You need a water softener, iron filter, or reverse osmosis system for those.
- Two main types of whole house systems: Backwashing carbon filters (self-cleaning, best for well water or heavy use) starting at $1,895, and non-backwashing upflow filters (no electricity, no drain, simpler installation) starting at $1,495. Backwashing systems start at $1,895.
- Media matters: We use Centaur catalytic activated carbon (coconut shell), which outperforms standard granular activated carbon at removing chloramines and hydrogen sulfide.
- Maintenance: Replace the carbon media every 3 to 5 years depending on usage and water quality. No chemicals, no electricity (for non-backwashing), no monthly costs.

What Carbon Filters Remove from Your Water
Activated carbon is effective against a wide range of contaminants. The EPA, NSF, and independent testing laboratories have established that carbon filtration reduces or removes the following:
For a complete maintenance schedule including carbon filter media replacement and every other system in your setup, read our well water system maintenance guide.
Removal percentages based on NSF/ANSI standards and EPA guidance for properly sized activated carbon systems. Actual performance depends on contact time, carbon type, water chemistry, and contaminant concentration.
Chlorine and Chloramines
For a focused buyer’s guide, see Best Whole House Water Filter for Chlorine. Municipal water treatment plants add chlorine or chloramines to disinfect the water supply. By the time it reaches your home, those chemicals have done their job, but they leave behind the taste and smell that makes your water unpleasant to drink, shower in, and cook with.
Standard activated carbon removes free chlorine extremely well. Chloramines are harder. Many cities have switched from chlorine to chloramines (a combination of chlorine and ammonia) because they last longer in the distribution system. Regular GAC carbon has limited effectiveness against chloramines. You need catalytic carbon to break the chloramine bond effectively. This is why we use Centaur catalytic carbon in all of our systems.
VOCs, THMs, and Chemical Contaminants
Volatile organic compounds (VOCs) include industrial solvents, fuel additives, and agricultural chemicals that can contaminate both well water and municipal supplies. Trihalomethanes (THMs) are disinfection byproducts created when chlorine reacts with organic matter in the water. To understand the full health picture, read Is Chlorine in Water Bad for You? Health Effects Explained.
Activated carbon is one of the most effective technologies for removing these compounds. The large surface area of the carbon provides millions of microscopic pores where these molecules are trapped and held.
Hydrogen Sulfide (Rotten Egg Smell)
If your well water has a sulfur smell, catalytic carbon can reduce hydrogen sulfide at moderate concentrations (typically under 3 ppm). For higher levels, you may need a dedicated sulfur filter with an air injection system. A carbon filter works well as a polishing stage after a primary sulfur treatment system.
Radon in Water
Granular activated carbon can adsorb dissolved radon gas from well water. This is particularly relevant in areas like New England and the Mid-Atlantic region, where elevated radon in groundwater is common. A homeowner in New Hampshire recently contacted us about radon in his well, and we recommended two non-backwashing carbon filters as part of his treatment chain. The carbon adsorbs the dissolved radon before the water reaches your faucets.
Important: PFAS and Carbon Filters
Activated carbon is one of three EPA-recognized treatment technologies for PFAS in drinking water. Large-bed GAC systems with adequate contact time can reduce long-chain PFAS (PFOA, PFOS) by 60% to 90% or more. However, shorter-chain PFAS compounds break through carbon beds faster, so for comprehensive PFAS removal, pairing a whole-house carbon filter with an under-sink reverse osmosis system or a dedicated PFAS ion exchange system provides the most complete protection. For a full overview of PFAS in drinking water, health risks, and treatment comparisons, see our Complete PFAS Guide and PFAS Water Filter Buyer's Guide.
How Carbon Filtration Works: Adsorption Explained
Carbon filters work through a process called adsorption (not absorption). The distinction matters: absorption is like a sponge soaking up liquid into its body. Adsorption is a surface process where contaminant molecules physically bind to the outside surface of the carbon.
Here's what happens inside the tank:
Untreated water flows into the top of the carbon tank. In a backwashing system, it flows downward through the carbon bed. In a non-backwashing upflow system, water enters from the bottom and flows upward.
As water passes through the carbon bed, contaminant molecules are attracted to the massive surface area of the carbon granules. A single pound of activated carbon has a surface area of approximately 100 acres. Chlorine, VOCs, and organic compounds bond to the carbon surface and are removed from the water.
The treated water exits through the valve and flows to every faucet, shower, and appliance in your home. The contaminants stay trapped on the carbon surface until the media is eventually replaced (every 3 to 5 years).
The key variable is contact time: the longer water is in contact with the carbon, the more contaminants it removes. This is why tank size matters. A larger carbon bed means more contact time, which means better filtration. Undersized systems rush water through the carbon too quickly, reducing effectiveness.
Why "Activated" Carbon?
Raw carbon (like charcoal) has some filtration ability, but activated carbon has been processed at extremely high temperatures (800 to 1,000°C) in the presence of steam or CO2. This process creates millions of microscopic pores in the carbon structure, dramatically increasing its surface area and adsorption capacity. For a deeper dive into how activation creates this pore structure, see What Is Activated Carbon? How Carbon Filters Actually Work.
Types of Carbon: GAC, Catalytic Carbon, and Carbon Block
Not all carbon is the same. The type of carbon media inside your filter determines what it can remove and how long it lasts. There are three main categories:
Granular Activated Carbon (GAC)
GAC is the most common form. The carbon comes in loose granules ranging from about 0.2 to 5 mm in size. Water flows through the granule bed, and contaminants adsorb onto the surface. GAC is effective for chlorine, taste, odor, and many organic compounds.
Limitation: Standard GAC is not effective at breaking down chloramines. If your city uses chloramines (many do, and the number is growing), you need catalytic carbon instead.
Catalytic Activated Carbon
Catalytic carbon is activated carbon that has been further processed to enhance its surface chemistry. The result is a carbon that not only adsorbs contaminants but also catalyzes chemical reactions on its surface. This is critical for chloramine removal, because chloramines need to be chemically decomposed, not just physically trapped.
This is what we use. Every MAW carbon filter ships with Centaur catalytic activated carbon made from coconut shell. Coconut shell carbon has a higher density of micropores compared to coal-based or wood-based carbon, which gives it superior adsorption capacity per unit volume. Centaur is manufactured by Calgon Carbon (now part of Kuraray), one of the largest activated carbon producers in the world.
Catalytic carbon handles everything standard GAC does, plus chloramines, hydrogen sulfide, and other compounds that require catalytic decomposition.
Carbon Block
Carbon block filters compress activated carbon into a solid block with very fine pore structures (typically 0.5 to 10 microns). Because the water must pass through the solid block rather than around loose granules, carbon block filters provide finer filtration and can remove some sediment and particulate matter that GAC cannot.
Carbon block is common in point-of-use applications: under-sink filters, countertop units, and refrigerator filters. It is less practical for whole house systems because the dense structure restricts flow rate. You cannot push 7 to 10 gallons per minute through a carbon block filter without multiple parallel units, which adds cost and complexity.
| Carbon Type | Best For | Chloramine Removal | Flow Rate | Typical Application |
|---|---|---|---|---|
| Standard GAC | Chlorine, taste, odor, VOCs | ❌ Limited | High | Whole house, some POU |
| Catalytic Carbon (Centaur) | Chlorine, chloramines, H2S, VOCs, taste | ✅ Excellent | High | Whole house (our systems) |
| Carbon Block | Chlorine, sediment, cysts, fine particles | ⚠️ Varies | Low | Under-sink, countertop, fridge |
Why Coconut Shell Carbon?
Carbon can be made from coal, wood, peat, or coconut shell. Coconut shell carbon has the highest percentage of micropores (pores smaller than 2 nanometers), which makes it the most effective at adsorbing small organic molecules like VOCs and chlorinated compounds. It also produces less dust and has a longer service life per unit volume. This is why premium water treatment systems use coconut shell carbon exclusively.
Whole House vs. Point-of-Use: Which Do You Need?
This is one of the first decisions you need to make, and the answer depends on what you're trying to accomplish.
Whole House Carbon Filters
A whole house system (also called point-of-entry or POE) installs on your main water line, typically near the pressure tank or where the water enters the house. Every faucet, shower, toilet, washing machine, and dishwasher gets filtered water.
This is what we recommend for most homeowners. Here's why: chlorine doesn't just affect your drinking water. You absorb chlorine through your skin in the shower, you breathe in chlorine vapor when hot water produces steam, and chlorine damages rubber seals and gaskets in your appliances over time. A whole house system eliminates chlorine from your entire water supply.
Point-of-Use Carbon Filters
Point-of-use (POU) filters treat water at a single location: an under-sink unit for drinking water, a showerhead filter, a refrigerator filter, or a countertop pitcher. These are convenient and less expensive, but they only protect one faucet at a time.
POU filters typically use carbon block cartridges that need replacement every 3 to 6 months. Over a 5-year period, the cost of replacing cartridges at multiple locations in your home often exceeds the cost of a single whole house system.
| Factor | Whole House | Point-of-Use |
|---|---|---|
| Coverage | Every faucet, shower, appliance | One location only |
| Chlorine in showers | Eliminated | Still present (unless shower filter installed) |
| Appliance protection | Yes, extends appliance life | No |
| Upfront cost | $1,495 to $2,495 | $30 to $300 per location |
| Ongoing maintenance | Replace media every 3 to 5 years | Replace cartridges every 3 to 6 months |
| 5-year cost (typical home) | $1,495 to $2,495 total | $600 to $1,500+ (cartridges for multiple locations) |
| Flow rate impact | Minimal with proper sizing | Reduced flow at that faucet |
A point-of-use filter makes sense as a supplement. A reverse osmosis system under the kitchen sink provides an additional level of purification for drinking and cooking water that even a whole house carbon filter cannot match. For a detailed comparison, see Carbon Filter vs Reverse Osmosis: Which Do You Actually Need?
Backwashing vs. Non-Backwashing Carbon Filters
Once you've decided on a whole house system, the next question is whether you need a backwashing or non-backwashing design. Both use the same Centaur catalytic carbon media. The difference is how the water flows through the tank and how the system maintains itself.
Non-Backwashing (Upflow Design)
Water enters the bottom of the tank and flows upward through the carbon bed. This upflow design gently lifts and redistributes the carbon with every use, which prevents channeling (water creating shortcuts through the media instead of contacting the full bed). No electricity, no drain connection, no backwash water waste.
Best for: City water applications, homes where simplicity matters, locations without a nearby drain or power outlet. This is what we recommend for most municipal water customers.
Backwashing (Downflow Design)
Water flows downward through the carbon bed during normal operation. On a timed schedule (typically every few days), the system reverses the flow and flushes the carbon bed to remove trapped sediment and redistribute the media. This requires a power outlet for the digital valve and a drain line for the backwash water.
Best for: Well water applications (where sediment is common), homes with high water usage, or situations where the water contains particulate matter that could clog a non-backwashing system over time.
| Feature | Non-Backwashing (Clack Upflow) | Backwashing (Fleck 2510SXT) |
|---|---|---|
| Water flow | Upflow (bottom to top) | Downflow (top to bottom) with periodic backwash |
| Electricity needed | No | Yes (standard outlet) |
| Drain connection | No | Yes |
| Self-cleaning | Upflow naturally redistributes media | Automated backwash cycle flushes sediment |
| Water waste | None | ~50 gallons per backwash cycle |
| Best water source | City/municipal water | Well water or sediment-heavy water |
| Installation complexity | Simple (inlet + outlet only) | Moderate (inlet + outlet + drain + power) |
| 1.5 CF price | $1,495 | $1,895 |
| 2.5 CF price | $1,695 | $2,495 |
Which One Does Aidan Use?
I have a non-backwashing carbon filter in my own house, paired with a water softener. I'm on a community well system, so I don't have heavy sediment issues. The simplicity is hard to beat: no electricity, no drain line, no wasted water, and it works quietly in the background. For a full comparison, read Backwashing vs Non-Backwashing Carbon Filters: Which Do You Need?
How to Size a Whole House Carbon Filter
Getting the right size is important. An undersized carbon filter causes two problems: reduced water pressure at your fixtures, and insufficient contact time that degrades filtration quality. An oversized system doesn't hurt performance, but it costs more than necessary.
The two variables that matter are your home's peak water demand (measured in gallons per minute) and the carbon volume (measured in cubic feet).
| Home Size | Recommended Carbon Volume | Tank Size | Service Flow Rate |
|---|---|---|---|
| 1 to 2 bathrooms (1 to 3 people) | 1.5 cubic feet | 10" x 54" | Up to 7 GPM |
| 3 to 4 bathrooms (3 to 5 people) | 2.5 cubic feet | 13" x 54" | Up to 12 GPM |
All of our carbon filters use Vortech tanks with a built-in distributor plate. This eliminates the need for a gravel underbed (which older tank designs required) and allows for more efficient water distribution through the carbon. The result is better contact time and lower pressure drop across the system.
The real-world sizing rule: If you're not sure, go with the larger tank. The cost difference between a 1.5 CF and 2.5 CF system is modest, and the extra carbon gives you more contact time, better filtration, and longer media life. I'd rather have a customer in a 2-bathroom house running a 2.5 CF system than the reverse.
Don't Forget Flow Rate on Well Water
If you're on well water, your well pump's output determines your maximum flow rate. A 5 GPM well can still use a 2.5 CF tank with no issues during normal operation, but the backwash cycle may need to be extended to compensate for the lower flow. Call Aidan at 800-460-5810 to confirm sizing if your well produces less than 7 GPM.
What Carbon Filters Do NOT Remove
This is where honesty matters. Carbon filters are excellent at what they do, but they have clear limitations. If a company tells you their carbon filter removes everything, they're misleading you. Here's what carbon cannot handle:
Hardness (Calcium and Magnesium)
Carbon has zero effect on water hardness. If you have scale buildup on fixtures, white residue on dishes, or stiff laundry, you need a water softener in addition to your carbon filter. See our detailed guide: Carbon Filter and Water Softener: Do You Need Both?
Iron and Manganese
Iron will actually damage a carbon filter. Iron particles coat the carbon surface and block the pores, reducing its ability to adsorb the contaminants it's designed to remove. If your water has iron above 0.3 ppm, you need an iron filter installed before the carbon filter. The iron filter protects the carbon downstream.
Bacteria, Viruses, and Microorganisms
Activated carbon does not disinfect water. In fact, a warm, moist carbon bed can actually become a breeding ground for bacteria if the water isn't already disinfected. If you're on well water and concerned about biological contamination, install a UV disinfection system after the carbon filter.
Nitrates and Fluoride
These dissolved inorganic compounds are too small and too chemically stable for carbon to capture through adsorption. A reverse osmosis system is the standard treatment for nitrates and fluoride at the point of use. For a detailed look at fluoride health concerns and removal options, see Fluoride in Drinking Water: What You Should Know.
Total Dissolved Solids (TDS)
Carbon does not reduce TDS. If your TDS reading is high, the dissolved minerals and salts pass straight through a carbon filter. This is normal and not necessarily a problem, but if you want to reduce TDS, reverse osmosis is the appropriate technology (see our comparison of RO vs other filter types to decide if it's the right fit).
Understanding these limitations is important because it determines whether you need a carbon filter alone or as part of a multi-system treatment chain. Most homeowners on city water only need a carbon filter (and maybe a softener). For more detail, see Carbon Filter for Well Water: Do You Need One?
Where Carbon Fits in Your Water Treatment Chain
If you have multiple water quality issues, the order in which you install your treatment systems matters. Each system protects the ones downstream from it. Here is the correct sequence:
For the full breakdown of where a carbon filter belongs in a multi-tank setup, see our guide on the correct order for well water treatment systems.
Catches sand, silt, and particulate before it reaches your treatment systems. Protects everything downstream. 10" Big Blue Sediment Filter ($165)
Removes iron, sulfur, and manganese before they reach and damage your carbon and softener. Iron Filter Guide
Corrects low pH to protect pipes, fixtures, and downstream treatment systems. Acid Neutralizer Guide
Removes hardness minerals. Install before the carbon filter so the softener handles the heavy lifting first. Water Softeners
Removes chlorine, taste, odor, VOCs, and polishes the water after upstream systems have done their work. Carbon Filters
Last in line. Kills bacteria and viruses in clean, clear water. UV requires water that's already filtered. UV Systems
Why carbon goes near the end: You want the water to be as clean as possible before it hits the carbon bed. Iron fouls carbon. Sediment clogs it. Hardness minerals don't damage it, but treating hardness first reduces the overall contaminant load. By the time water reaches the carbon filter, it should be free of particulate and heavy contaminants so the carbon can focus on what it does best: removing dissolved chemicals, chlorine, and taste/odor compounds.
For city water, the chain is much simpler. Most municipal water customers only need two systems: a water softener (if the water is hard) followed by a carbon filter. We sell carbon filter and water softener packages designed for exactly this setup.
For a deeper dive into how all these systems work together, read our Complete Guide to Well Water Filtration Systems.
Our Carbon Filter Systems
We offer four standalone carbon filter systems and two carbon + softener combination packages. Every system uses Centaur catalytic activated carbon (coconut shell) in a Vortech tank. All prices include free shipping to the contiguous United States.
Standalone Carbon Filters
| System | Type | Carbon Volume | Tank | Best For | Price |
|---|---|---|---|---|---|
| Clack 1.5 CF Non-Backwashing | Upflow (non-BW) | 1.5 cu ft | 10" x 54" | City water, 1 to 2 bath | $1,495 |
| Clack 2.5 CF Non-Backwashing | Upflow (non-BW) | 2.5 cu ft | 13" x 54" | City water, 3+ bath | $1,695 |
| Fleck 2510SXT 1.5 CF Backwashing | Downflow (BW) | 1.5 cu ft | 10" x 54" | Well water, 1 to 2 bath | $1,895 |
| Fleck 2510SXT 2.5 CF Backwashing | Downflow (BW) | 2.5 cu ft | 13" x 54" | Well water, 3+ bath | $2,495 |
Carbon + Water Softener Packages
If you need both a carbon filter and a water softener, these packages save you money compared to buying the systems separately. Both include free shipping.
| Package | Carbon Filter | Water Softener | Best For | Price |
|---|---|---|---|---|
| Clack Carbon + Fleck Softener | Clack 2.5 CF Non-BW | Fleck 5600SXT 64,000 Grain | City or well, up to 4 bath | $3,295 |
| Fleck Carbon + Fleck Deluxe Softener | Fleck 2510SXT BW | Fleck 2510SXT Deluxe | Heavy use, 3+ bath, well water | $3,695 |
Every System Includes
Vortech tank (USA-made), Centaur catalytic activated carbon (coconut shell), control valve (Clack or Fleck depending on model), stainless steel bypass valve, and free shipping. Installation is DIY-friendly with free tech support from Aidan at 800-460-5810.
Replacement Carbon Media
When it's time to replace the carbon (every 3 to 5 years), you can order the media separately:
The process is straightforward: take the tank offline, dump the old carbon, rinse the tank, pour in the new carbon, and put it back into service. The tank itself lasts decades. You only replace the media inside.
Maintenance and Media Replacement
One of the biggest advantages of a whole house carbon filter is low maintenance. There are no chemicals to buy, no salt to add, and no cartridges to change every few months.
| Component | Expected Lifespan | Maintenance | Estimated Cost |
|---|---|---|---|
| Vortech Tank | 40 to 50 years | None | $0 |
| Control Valve (Clack or Fleck) | 10 to 15 years | Minor seal or piston kit if needed | $50 to $150 (parts) |
| Centaur Carbon Media | 3 to 5 years | Replace entire carbon bed | $200 to $600 (depending on size) |
How Often to Replace the Carbon
Carbon media life depends on three factors: how much water flows through it, what contaminants are in the water, and the volume of carbon in the tank. For a typical household:
- City water (chlorine/chloramine removal): 3 to 5 years. Municipal water is relatively clean, so the carbon's adsorption capacity lasts longer.
- Well water (sulfur, VOCs, organics): 2 to 3 years. Well water often carries higher contaminant loads that exhaust the carbon faster.
You'll know the carbon is spent when the chlorine taste or sulfur smell starts returning. That's the signal to replace the media. Some customers test their water periodically to track when breakthrough occurs.
Cost of Ownership Over 10 Years
Here's the real math for a 2.5 CF non-backwashing carbon filter on city water:
- Initial system cost: $1,695
- Carbon replacement at year 4: ~$500
- Carbon replacement at year 8: ~$500
- Total 10-year cost: ~$2,695 (approximately $22 per month)
Compare that to buying bottled water, replacing pitcher filters, or running multiple point-of-use cartridge filters throughout the house. The whole house system is the most economical approach over time.

When Carbon Isn't Enough
Carbon filters excel at chlorine, taste, and VOCs. But for lead, arsenic, nitrates, and fluoride, you need reverse osmosis. See RO vs Other Water Filters for a detailed comparison, and our Best Under-Sink Water Filter Guide for all under-sink options.
Frequently Asked Questions
Do carbon filters remove chlorine?
Yes. Carbon filtration is the EPA-recommended method for removing chlorine from drinking water. Activated carbon reduces free chlorine by over 99%. For chloramines (which many cities now use instead of chlorine), you need catalytic carbon rather than standard GAC. All of our systems use Centaur catalytic carbon, which handles both chlorine and chloramines effectively.
What's the difference between a carbon filter and a water softener?
They solve completely different problems. A carbon filter removes chlorine, taste, odor, VOCs, and chemical contaminants. A water softener removes hardness minerals (calcium and magnesium) that cause scale buildup, soap scum, and dry skin. Many homeowners need both systems. We offer carbon filter and water softener packages for this reason. The softener installs first, followed by the carbon filter.
Can a carbon filter remove iron from water?
No. A carbon filter is not designed for iron removal, and iron will actually damage the carbon by coating its surface and blocking the pores that adsorb contaminants. If your water has iron above 0.3 ppm, install a dedicated iron filter upstream of the carbon filter. The iron filter protects the carbon so it can focus on chlorine and chemical removal.
How long does the carbon media last?
Typically 3 to 5 years for city water and 2 to 3 years for well water. The lifespan depends on water usage, contaminant levels, and the volume of carbon in the tank. Larger tanks (2.5 CF) last longer than smaller ones (1.5 CF) because there is more carbon to do the work. You'll know it's time to replace the media when you start noticing the chlorine taste or sulfur smell returning.
Do I need a backwashing or non-backwashing carbon filter?
For city water, a non-backwashing system (Clack upflow design) is the best choice. No electricity, no drain, simpler installation, and the upflow design naturally prevents channeling. For well water, a backwashing system (Fleck 2510SXT) is better because the automated backwash cycle flushes out sediment that accumulates in the carbon bed. See the full comparison above.
Can I install a whole house carbon filter myself?
Yes. All of our carbon filter systems are designed for DIY installation. A non-backwashing system requires only two plumbing connections (inlet and outlet). A backwashing system also needs a drain line and a standard electrical outlet. Basic plumbing skills and a few hours are all that's needed. Aidan provides free tech support by phone at 800-460-5810 if you need help during installation.
What does a whole house carbon filter cost?
Our standalone carbon filters range from $1,495 to $2,495 depending on the size and type (backwashing vs. non-backwashing). Carbon + water softener packages range from $3,295 to $3,695. All prices include the tank, carbon media, valve, bypass valve, and free shipping. The only additional cost is installation (DIY or a local plumber) and carbon media replacement every 3 to 5 years.
Do carbon filters remove PFAS?
Activated carbon can reduce some PFAS compounds, but it is not a certified complete solution for PFAS removal. The EPA recommends activated carbon as part of a multi-barrier approach. For the most thorough PFAS protection, pair a whole house carbon filter with a point-of-use reverse osmosis system at the kitchen sink. The RO membrane provides an additional level of PFAS reduction that carbon alone cannot match.
What is the difference between activated carbon and charcoal?
Charcoal is carbon that has been burned (pyrolyzed) at high temperature. Activated carbon is charcoal that has been further processed with steam or CO2 to create millions of microscopic pores, dramatically increasing its surface area and adsorption capacity. For more on this distinction, read Charcoal Water Filter: Are They the Same as Carbon Filters?
Does a carbon filter reduce water pressure?
A properly sized carbon filter causes minimal pressure drop (typically 2 to 5 psi). The key is choosing the right tank size for your home's flow rate. Our 2.5 CF systems handle up to 12 GPM with negligible pressure loss. Problems arise when homeowners use undersized systems. If you're concerned about pressure, go with the larger tank size.
