Why I Chose an Under Sink Water Filter
I wanted a solution that wouldn’t clutter my countertop and could provide clean, great-tasting water straight from the tap. Under sink filters are discreet, easy to maintain, and often deliver better filtration compared to pitcher or faucet-mounted options.
Key Features I Considered

- Installation Ease: Since I’m not a professional plumber, I preferred a model that comes with clear instructions and easy installation kits. Many Filtrete under sink filters can be installed with basic tools in under an hour.
- Water Flow Rate: I wanted to ensure the filter wouldn’t slow down my water flow too much. Filtrete models usually maintain good flow rates, but it’s worth checking the specs.
- Certification: I made sure the filter is NSF/ANSI certified for the contaminants it claims to reduce. This certification gives me confidence in the product’s effectiveness.
