Aquasana AQ-4501 Review

Aquasana AQ-4501 Polished Chrome
The Aquasana AQ-4501, Voted the best buy water filter system 5 years in a row by Consumers Digest, provides pure fresh drinking water for under 10 cents a gallon by using a patented 2 stage filetr that combines carbon filtration, ionic exchange, and sub-micron filtration. Never buy bottled water again. According to Consumers Report almost 50% of bottled water produced in the U.S. is purified tap water-not some pure mountain stream.

The Aquasana AQ-4501 unique filtration system rids regular tap water of chlorine, minerals, lead, medications, and other contaminates that leach into municipal water systems leaving you with refreshingly clean water. The State of California has certified the AQ-4501 with the Department of Public Health Services for its effectiveness. (Click Here to view certificate).


Installation is pretty straight forward if you are comfortable with common hand tools as all of the hardware is supplied. The most daunting task might be drilling a 7/8' hole in your sink or counter top. That's only if there's no hole for a sprayer. However if you're up to it a heavy-duty hand drill and suitable hole bit will do the trick. If overwhelmed a plumber can install it for you at a reasonable rate.


Unlike other faucet filtration systems that attach to the faucet directly the AQ-4501 is stand alone. Meaning whenever you use hot water it doesn't need to be bypassed to protect the filter element. Just turn the knob and you're good to go.


The Aquasana AQ-4501 is available in 3 distinct colors: Glossy Black, Polished Bronze, and Polished Chrome just enough variety to please even the most discerning decorator.

Great tasting water

Filters hidden out of sight

One of the things that might discourage purchase is the fact that in order to install the stand alone faucet a 7/8inch hole may need to be drilled in the sink or counter top. While not difficult some may be daunted by this task.

Filter containers are made from plastic. No really a big deal since they mount out of harms way.

On the whole the majority of people were quite satisfied with the Aquasana AQ-4501 Under Counter Water Filter System. Most problems suffered were minor and had little impact with the AQ-4501 performance. If you're truly concerned about water quality, I recommend the Aquasana AQ-4501 Complete Under Counter Water System.
