How to choose
Filtration Performance
Look for filters that target the contaminants in your water. Pitchers are good for taste, but under-sink systems handle more. Check NSF certifications for lead, chlorine, and sediment.
Cost Per Gallon
A cheap filter isn't a bargain if you replace it often. Calculate the cost per gallon: divide filter price by gallons treated. Pitchers average /gal, while under-sink can be /gal.
Ease of Installation
If you rent or have a small kitchen, choose a pitcher or faucet mount. Under-sink filters require drilling but save counter space. Countertop models are a middle ground.
Filter Life
Longer filter life means fewer replacements. Pitchers need changing every 2 months, while under-sink filters last 6-12 months. Balance longevity with performance.
The bottom line
The best budget water filter isn't always the cheapest upfront—consider cost per gallon and filter life. Pitchers are great for beginners, but under-sink systems offer the best long-term value.
