About - Aquasana AQ-4000

The Aquasana AQ-4000 is part of the water filter test program at Consumer Reports. In our lab tests, water filter models like the AQ-4000 are rated on multiple criteria, such as those listed below.


Lead removal:
Lead removal indicates the percentage of lead that was removed by each filter.

Chloroform removal:
Chloroform removal rates the percentage of chloroform removed. A filter's ability to remove chloroform predicts how well it will remove organic compounds as well as byproducts created by disinfectants used by water systems.

Flow rate:
Flow rate is how fast a gallon of water filtered through the cartridge. The criteria for flow rate scores differ between different types of filters. Faucet-mount, countertop, and undersink models have the same criterion; carafes and reverse osmosis models each have their own.

Comment:
I have purchased 3 different variations of this product, both under counter & countertop. I have never had any of them leak. They have each given great service. I especially love the auto ship feature for getting new filters shipped every 6 months. You don't need to remember to order your filters, and you always have fresh water. No lugging gallons of water home!

I have had several rage episodes trying to replace parts, spontaneous leaks, etc. Don't purchase this! Fine until you have to replace filter (every 6 months). Clean water is not worth this aggravation. Really aggravating! Avoid avoid avoid! From one very regretful customer. Buy bottled water! Save yourself from having a coronary!

Comment:
Have had this for about 2 years. Every time filter and hose need to be changed something breaks or begins leaking. <br /><br />very frustrated with the leaking and needing to call the company for replacement. <br /><br />Will not purchase this product again until they work on the leaking and breaking issues that occur often.
