Buying Guide: How to Choose a Countertop Water Filter
Here’s what to consider before picking your system:
1. Filtration Method
Carbon filters improve taste and odor. Reverse osmosis removes the most contaminants. Gravity-fed systems work without plumbing or power.
2. Capacity
Large families should go for 2+ gallon units like the Big Berkey or Zen Water. Singles and couples can stick to compact models.
3. Certifications
NSF/ANSI certifications ensure the filter performs as claimed.
4. Maintenance
Some filters need cartridge replacements every 3–6 months. Others (like CleanWater4Less) last for years without replacements.
5. Aesthetics
If it’s going to live on your counter, you may want something stylish like the Brondell Cypress.
FAQs
Do countertop water filters remove fluoride?
Reverse osmosis systems like the APEC Countertop RO can remove fluoride, while standard carbon filters typically do not.
How often should I replace countertop filter cartridges?
Most need replacement every 3–6 months, but long-life options like Big Berkey last years before cartridge changes are needed.
Are countertop water filters good for apartments?
Yes—they don’t require permanent installation and are renter-friendly. Faucet models disconnect easily, and gravity-fed options need no plumbing at all.
Do these slow down water flow?
Some faucet-connected systems slightly reduce flow, but gravity-fed systems are slower by design. For fast flow, look for models with higher rated capacity.

Countertop water filters are a game-changer for anyone who wants clean, safe, and great-tasting water without the hassle of plumbing.
From plug-and-play RO systems like the Waterdrop WD-M1, Aigerri UV, and Hydrofast B100, to high-capacity favorites like the Big Berkey or APEC, there’s a solution for every lifestyle, kitchen size, and budget.
