Rated 5 out of 5 by from I'm overall impressed!! We have the 1,000,000 gal whole house conditioner combo that we had installed about two months ago and what a difference it has been. The water not only taste great but there's no smell of chlorine. We had some friends over for dinner last week and they couldn't stop saying how great the water tasted and couldn't believe it was tap water. All I can say is we're so happy that we had the system installed and will recommend it to anyone. Also, the ladies at the Texas office was so informative, courteous and friendly when we called to ask questions. Thank you!

Rated 5 out of 5 by from Whole House Pre-Filter Cartridges performing well We are very pleased with the performance of the filter. When we replaced the first filter, it was clear that the pre-filter was working quite well. Will purchase again.

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 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.

Will a four pack of filters last about 1 year?  You only use one filter at a time right?  

Asked by: Hilsbury
Thank you for your inquiry. Pre-filters should be replaced every 2 months depending on the sediment in your water. The easiest way to tell is to look at your pre-filter and when it turns brown it is full of dirt/sediment and should be replaced. If you need future assistance, please let us know!

Asked by: Tranquility
The post filter should be changed once every 6 months minimum. If you experience a slower flow in your water, it is an indicator that the filters should be changed.

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.

Why does the 10” filter have a 5 micron rating, but the 20” have a 20 micron rating?  It seems like the filtration quality ahead of the main unit should be the same... with the taller cartridge just providing more longevity.
