Three filters below were checked on Amazon on October 10, 2026. The nine others are sold on maker or dealer sites, so details are the makers’ claims and prices were not re-checked. The New Wave Enviro listing from older versions of this guide is now only a replacement cartridge and was removed. Always read the certificate for the contaminants a filter is tested to reduce.
A countertop filter is the easiest upgrade for tap water. There is nothing to cut or drill, and most units are ready in minutes. The hard part is choosing among them, because the claims vary a lot. This guide sorts the types, lists twelve models to look at and shows what to check before you buy.
Table of Contents
The Main Types
- Gravity filters. Water moves through the elements by its own weight. No power, no plumbing. Slow, but simple. The Big Berkey is the best-known.
- Faucet-connected filters. A diverter hose runs from the faucet to the unit. Faster, and they need a compatible faucet.
- Countertop RO. Pushes water through a fine membrane. Removes most dissolved solids. Needs power and tank cleaning. See our countertop RO guide.
- Alkaline or mineral units. Add minerals after filtering. They change the taste, and health claims are weak.
What They Do and Do Not Do
- Carbon-based filters reduce chlorine, taste, odor and some chemicals.
- Some filters reduce lead, if certified for it.
- Most gravity and carbon filters do not remove dissolved minerals, and many do not remove fluoride without an add-on.
- No filter should be treated as a way to make unsafe water safe, unless it is made and certified for that.
Looking ahead, countertop water filters are splitting into two camps: simple gravity and pour-through filters that need no power, and powered RO units with screens and apps. Worries about PFAS, lead and microplastics keep pushing demand up. The catch is that long contaminant lists on a box do not always match a lab certificate.
Certificates: What to Look For
NSF/ANSI 42 covers taste and chlorine. NSF/ANSI 53 covers health claims such as lead. NSF/ANSI 58 covers RO systems. The Water Quality Association (WQA) also certifies products. A real certificate names the contaminants and the percentage reduced. Older versions of this guide used phrases such as “removes at least 90 percent of contaminants”. That kind of line is not meaningful, so look for the named list instead.
9 Countertop Filters From Makers and Dealers
The details below come from maker pages. Confirm the certificate, the filter life and the price before you buy.
1. AquaTru Countertop Water Purifier
A countertop RO unit that needs no plumbing. The maker lists testing to NSF/ANSI standards against a long list of contaminants. Read the product page for the exact standards.
- RO membrane
- No installation
- Filters need regular changes
2. ProOne ProMax Countertop Filter
A countertop filter from ProOne. The maker says it is made to reduce a range of contaminants, and sells it with its own elements. Check the test list on the maker page.
- Countertop
- Maker-listed tests
- Check element life
3. Epic Pure Water Filter Dispenser
A pour-through dispenser from Epic, a brand known for its published lab data. Check the product page for the contaminants it was tested on.
- Pour-through dispenser
- No power
- Check the test data
The risk to watch is the wrong match. A gravity filter does not remove dissolved minerals or fluoride unless it has a special element, and an RO unit removes almost everything but needs more upkeep. Expect buyers to pick on a big marketing number and find out later that the unit does not target their problem. Test the water or read the utility report first.
4. Aquasana AQ-4000W Claryum Countertop Filter
A faucet-connected filter that uses the Claryum media. Aquasana lists its tested contaminants on the product page, so check the current list.

How to Choose
- Know your water. Read the utility report or run a lab test. See our gravity water filters for no-power options.
- Match the certificate to your concern, such as lead, PFAS or chlorine.
- Check the space. Measure the counter and the height under the cabinets.
- Check the faucet. Faucet-connected units need a compatible tip.
- Count the filter cost. Filters last from a few months to a few years.
- Clean the unit. Wash the housing and tanks as the manual says.
FAQ
Are countertop filters better than pitchers?
They hold more and often filter more types of contaminants. See water filter pitchers and dispensers for the other option.
Do they remove fluoride?
RO units do. Many carbon filters do not, unless they add a special element.
Do countertop filters need installation?
Gravity and pour-through units do not. Faucet-connected units need a quick hose connection.
Final Word
A countertop filter is a simple way to cut chlorine, taste and some contaminants. Match the certificate to your water and plan for filters. For faucet-mounted options, see faucet water filters.
What happens next: more makers will publish third-party lab results, and shoppers will start asking for them. Pick on your water report, the certificate and the yearly cost of filters, and skip claims of “99 percent” with no named contaminant.
