Rated 5 out of 5 by from Bad water is now good water We have been using a whole house system for a private well for about 2 months now. The water used to be very high in iron, left stains on everything and smelled awful! Since the system has been installed we have no more staining, no more smell and the water looks and tastes great. We also installed the UV light so now we don't have to worry about letting the grandkids drink the water! Easy install too with the included pro install kit, about 2 hours start to finish.

Rated 5 out of 5 by from Aquasana Rocks! Aquasana is amazing. Their support is superb and their products are shipped in a timely basis. I have a whole house system for our house in Mexico and have an occasional question about how to do something. They never fail to respond in a timely and helpful manner.

Rated 5 out of 5 by from These filters work well. These pre-filters change easily and filter out a lot of crud. Easiest part of the system. (Although I would order my entire system locally next time, the customer service has been decent.) The maintenance of changing the pre/post filters is quite easy.

Rated 5 out of 5 by from Great value. Delicious water. We turned off the Aquasana when we installed the new one. I had a drink upstairs before switching the new one on. I couldn't believe the difference. Like locking a flagpole. Don't think I'll be switching the new one off ever... Delicious water.

These 20 inch filters look slim I need 20 inch but it seems like mine are more round / thicket????

Asked by: Kregg Moyer
Hi Kregg! We only have one type of 20 inch pre filters. So as long as you have an Aquasana system, these will be the right ones. Thank you, Aquasana Customer Support

In GALLONS when should the prefilter be replaced?

Asked by: Neil_H
Because the pre filter is there to filter out rust, sediment, silt, and other larger debris particles, there is no particular gallon capacity for these filters. It will depend entirely on the quality of your water as it enters the system. The filter typically needs to be changed every 2 months, however if you feel that your water quality does not warrant that, then you can check the filter periodically and when it is a dark tea color then you know it's time to switch it out.
