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!

When does the sub micron apost filter need to be changed?

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.
