Rated 5 out of 5 by from pre-filters and regular filters The taste of the water is excellent. The pour is variable depending on whether there is any work being done on the outside. My filters usually start to slow down the pour around the fourth or fifth month but I can live with this.||I use the product mainly for drinking but I also rinse my salads with it.||To me the best thing about it is the taste of the water.

Rated 5 out of 5 by from Great product! This product is great! I am using it for 5 years and recommended it to all of my friends and family. I cannot believe how much gunk the filters take out of the water. I shudder when I think that we used to ingest all of that.

Rated 5 out of 5 by from They Work The pre-filter filters keep my main filters unclogged longer. I live in a silty-water district and have learned that Aquasana is addressing the problem of clogging filters by re-engineering the main filters. I'm thrilled that they acknowledge and do the work to fix problems that come up. Very good customer service. Worth hanging in there with this company when there are problems. And the filters a

Rated 4 out of 5 by from Good Pre-filter Before using the pre-filter, the pressure with which the water came out of the faucet slowed down considerably in only two months. The pre-filter has helped that.

Rated 4 out of 5 by from Happy with improved water flow and better filtering Water flow was slowing down in last 2 months before filter change was due. Adding the prefilter is extending the life of the water filters and allowing a longer steady pour. The prefilter turns brown over 5-6 weeks use, clearly showing the sediment removed.

Rated 4 out of 5 by from Pre-filter ease of use Love the pre-filter's ease of replacement. Since we live at the Jersey Shore and the folks coming down from up north are filling their pools, water levels are lower in the area reservoirs and our pre-filter needs changing every, one to 2 weeks because of the red silt that is in our water. We can always tell when the filter was just changed; the water tastes so much better. Can't believe so many pe

We can always tell when the filter was just changed; the water tastes so much better. Can't believe so many people allow their families to drink the water without some form of filtration. I love my family and anything that I can do to help them stay healthy is a priority to me.

Rated 3 out of 5 by from Would not have bought if I had known... I used it to replace the hose on an existing above the sink filter. The hose is fine. The filter is extremely difficult to place. Had to use a rubber mallet to get it to go down. Still trouble screwing the top back on. When finally on, it spurted water everywhere. Took it off and tried again. Still leaked. Finally had to get the plumbers tape out to stop the leak. Dread having to change that filter in a few months. Wish I had kept the old tubing!!!!

User Q & A

How big are these prefilters that come in a 6-pack? Once I think i ordered them and they were much too small. My prefilter needs filters that are about 4 inches tall. Are these them? Please put specs on these it would help when trying to order! Thanks

Asked by: Andrea Legge
The pre-filters for our Counter Top system are 1.5" tall and designed to fit the Diverter Pre-filter.
