Buying Guide
When choosing a faucet filter, first verify it is compatible with your faucet model, as they do not work with pull-out or handheld sprayers.
Prioritize filters with NSF certifications (especially NSF 53 for lead). Finally, compare the filter lifespan (in gallons) and the cost of replacement cartridges to determine the best long-term value for your household.
What is a Faucet Water Filter?
A faucet water filter is a compact water purification device that attaches directly to the threaded end of a standard kitchen faucet. Inside the unit is a replaceable filter cartridge, which typically contains activated carbon and other filtration media. When you turn on the water and engage the filter, water is forced through this cartridge, which captures and reduces a variety of contaminants like chlorine, lead, sediment, and certain chemicals. A simple lever or switch on the unit allows you to bypass the filter and use regular, unfiltered tap water for tasks like washing dishes.
Helpful Information
How to Install and Use a Faucet Filter
Installation:
- Unscrew the Aerator: Twist off the small screen piece (the aerator) from the tip of your faucet.
- Find the Right Adapter: The filter will come with several plastic or metal adapters. Find the one that fits the threads on your faucet.
- Attach the Filter: Screw the adapter onto the faucet, then screw the filter unit’s mounting collar onto the adapter until it is snug. Do not overtighten.
How to Use:
Almost all faucet filters have a diverter switch. When the switch is in one position, regular tap water flows out. When you flip the switch to the other position, the water is redirected through the filter cartridge, providing you with purified water.
Tips
- Use Unfiltered Water for Dishes: To maximize the life of your filter cartridge, only use filtered water for drinking, cooking, and preparing beverages. Switch to unfiltered tap water for washing hands and dishes.
- Never Use Hot Water: Running hot water through the filter can permanently damage the filtration media inside the cartridge, rendering it ineffective. Only use cold water with the filter engaged.
- Change Your Filter on Time: A filter is only effective for its rated lifespan. Change the cartridge as recommended by the manufacturer (usually every 2-3 months or 100 gallons) to ensure you are always getting properly filtered water.
- Prime a New Filter: When you first install a new filter cartridge, it’s a good practice to run cold water through it for about 5 minutes to flush it out and activate the filtration media.

FAQ
Q: Do faucet filters remove fluoride?
A: Most standard faucet filters that use activated carbon (like Brita and PUR) do not remove fluoride. However, some brands like Waterdrop use advanced media that can reduce fluoride, but it’s important to check the specific product’s certified claims.
Q: How do I know if a faucet filter will fit my faucet?
A: Faucet filters are designed to fit most standard faucets with a removable, threaded aerator. They will not work with pull-out hoses, handheld sprayers, or faucets with irregular shapes. All filter kits come with a variety of adapters to fit both internal and external threads.
Q: Is a faucet filter better than a water pitcher filter?
A: It depends on your needs. A faucet filter is much more convenient, providing instant access to filtered water without waiting. It also typically filters out more contaminants (especially lead) than a standard pitcher filter. A pitcher is portable and requires no installation, but it filters slowly and needs frequent refilling.
