Aquasana Countertop AQ-4000 Review: The Pros

Being one of the popular countertop filters in the market, the Aquasana AQ-4000 does come with several advantages.

1. Quick and Simple Installation

The AQ-4000 countertop filter is designed to be easily installed on the countertop to start providing clean drinking water to your family.

Some manufacturers may make a wild claim about their water filters in terms of filtration capabilities, but without certification from independent 3rd party organizations like NSF, those claims are still a question.

The countertop system has a flow rate of 0.5 gallons per minute, which is good as you can fill up a standard 8 oz. glass in about 7 seconds.
