Aquasana Under Sink vs Countertop

Installation type

Edge: Tie

Product A is an under sink unit designed for direct connection to your cold water line. It requires no dedicated faucet or drilling into your countertop, though you do need 3 inches of clearance for filter changes. Product B sits on your counter and needs no plumbing at all. You simply fill the reservoir and wait. If you rent or cannot modify your kitchen structure, Product B is the easier choice. If you have cabinet space and want hidden plumbing, Product A fits better.

Physical dimensions

Edge: Tie

Product A measures 4 by 4 by 20.5 inches and weighs 5 pounds. It is tall and narrow, designed to fit vertically under a sink. Product B is wider and shorter, measuring 9.69 by 7.96 by 11.6 inches. It weighs 6.2 pounds. The countertop model takes up more surface area but has a lower profile. You need to check your counter space for Product B and your under-sink clearance for Product A. Both are compact, but their shapes suit different locations.

Filtration method

Edge: Tie

Both systems use Claryum technology to remove up to 99% of 78 contaminants, including lead, PFAS, and mercury. They both retain healthy minerals like calcium and magnesium. Product B uses Power Activated Filtration to force water through an ultra-dense block, producing an 8-ounce glass in 8 seconds. Product A uses standard carbon filtration connected to your line. The core cleaning power is identical. The difference is how the water moves through the filter media. Both retain minerals and do not reduce TDS.

Filter lifespan

Edge: Aquasana Countertop Water Filter AQ-CWM2-B

Product B states its filter lasts up to 300 gallons or 6 months. It also claims to last 7.5 times longer than leading pitcher filters. Product A mentions one filter replaces more than 6,250 plastic bottles, but does not list a specific gallon capacity or time frame in the provided data. Without a specific capacity for Product A, we cannot definitively compare longevity. You should check the manual for Product A’s exact replacement schedule. Product B gives you clear metrics for planning.

Water flow rate

Edge: Aquasana Claryum Direct Connect Under Sink

Product B delivers an 8-ounce glass in 8 seconds. This is a manual fill process. You pour unfiltered water in and wait for the filtered output. Product A connects to your faucet line. It provides continuous water on demand, limited only by your home’s water pressure and the filter’s flow rate. The data does not list gallons per minute for Product A. For quick access to drinking water without waiting, Product A is more convenient. For batch filtering, Product B works fine.
