The Best Under-Sink Water Filter: Aquasana AQ-5300 vs. Propur Inline Connect FS10
While gravity-fed water filters are high quality and do well in many different applications, they’re not so great if you don’t plan ahead. For on-demand drinking water you have to look elsewhere. That’s why filtration systems that hook up to your kitchen sink are so popular.
These types of systems come in two flavors: countertop and under-counter. I prefer the under-counter variety since it’s out of sight. Of course, they require some mild installation, but this shouldn’t be a hindrance. Manufacturers have made these systems much more amateur-friendly in the 30+ years since my parents bought their first system to go under the sink.
