An under counter filtration system is great for getting great water without having to store a filter or buy bottled water. Some will be okay with the countertop filters but they’re not typically as effective and they take up a bit of space. Bobvila ranks the iSpring RCC7P-AK 6-Stage Reverse Osmosis System as the best overall system. The reverse osmosis filters up to 1000 toxins and is great when water quality is very poor. You’ll want to make sure the system you get doesn’t waste too much water.

Key Takeaways:

• Attributes to look for include size, capacity, flow rate (speed), water pressure (force), odor removal, and ease of installation.
• The best reverse osmosis systems include the iSpring RCC7P-AK with its electric pump, and the budget-friendly Express Water RO5DX.
• APEC Water Systems ROES-PH75 is our recommended model for those who want to drink alkaline water.

“Countertop filters can be effective, but may also be a bit of an eyesore and take up valuable counter space. Under-counter models keep the mechanics out of sight while providing filtered water right at the kitchen sink. The best under sink water filters have multiple levels of filtration to offer clean water right at your fingertips.”
