REVIEW

Our top pick for 2020’s best countertop RO system is the Apec Water Systems RO-CTOP Portable Countertop RO water filter system. This 4-stage filtration system is designed and made here in the US, along with most of its BPA-free components [1]. All the filters are NSF certified for safety with an average 12 month lifespan, depending on the level of contamination.

There’s no assembly required and a very minimal installation setup that’s quite straightforward. All the connections are included for attaching the RO-CTOP easily to any standard faucet in your kitchen, bathroom, basement, office, etc. The company does warn, however, that this unit isn’t compatible with pull-out faucets, special size designer faucets and sprayer faucets.

Filter changes are extremely easy. No tools are required to remove the filter cartridges. They just twist and snap into place. At only seven pounds, you can take this unit to your cottage or on your yacht, for example, and it will work with any system with a water pressure rated 40-80psi.

Note: Filter replacement will cost you $100-$200 per year. ( varies depending on level of contamination, water pressure and level of use)
