Less Expensive Replacement Works Well
By Elliot G on 8/2/2017
Works well. However, the original Aquasana® filter seemed to do a better job of removing some of the hard-water minerals.

Half the price of Aquasana
By henry on 6/6/2017
We used to use Aquasana for our drinking water and for our shower, but decided to give this filter a try as a replacement as it was nearly half the price. It's only been 2 weeks, but so far all seems well. We have very hard water and it was stripping out hair and skin of moisture.

Five Stars
By SSFVW siyuezhifeng on 8/17/2016
It's great. It has been used for two years, and the filtration effect is very good.

Yes, it works well on AQ-4100.
For optimum results, it is recommended you change the filter every 6 months or 10,000 gallons of water, whichever comes first and will vary with water condition.
Yes, it is a necessity to flush the filter before first use. There may be carbon fines around the filter, but it is quite normal, so it is advisable to flush the filter before using to remove carbon fines and any trapped air.
