Still are number one seller is the Aquasana 4000 also know as the AQ-4000 counter top filter. This easy to use filtration system is the best value going anywhere!  That’s a big statement but when you look at all of the competition out there then you understand why this sells so well. The Aquasana filter is a twin-cartridge system. It’s easy to connect and just takes a minute to accomplish.  The filters need replacing every six months for best performance.

Factoring in all of the costs you will get pure clean filtered water for under 10 cents per gallon. Compare that with plastic bottled water at an average price of over  $3.50 per gallon and you can see why people are purchasing. This filter is also available as an under sink model. Either way you are getting a great filter at a great price. I hope your family enjoys their countertop filter as much as ours.
