Rated 5 out of 5 by from Awesome! We have city water but still have a whole house water filter and the pre-filter system too. Over the summer I needed the local water department to come to our home due to sediment in our water lines. As part of the procedure they tested the water not knowing we had a filter. They said - "there is nothing in this water... except water". Yes, they couldn't find a trace of anything. We go thru quite a few pre filters due to the continuing sediment problem but it is soooooo worth it!

Rated 4 out of 5 by from Filter is in and working I use this filter as my primary domestic fresh water filter. I use the pre-filter, follwed by an Iron filter, finally the whole house filter. I do go through many pre-filters due to iron in the well and this was expected. On the initial installation, there either was a crack in the top housing of the iron filter or I may have over-tightened it, but it was replaced. I did not over-tighten the fitti

Rated 5 out of 5 by from Aquasana I cannot express enough how pleased I am to have an Aquasana household filtration system in my house! My water is clean, pure, and safe! Before installing the Aquasana water filtration system in my home my water smelled of heavy chlorine and had all sorts of visible particles in the water. I believe that you take risks with your health if you drink tap water without a filter system. Thank you fo

Rated 3 out of 5 by from They don't make 'em like they used to. These prefilters used to last me between 3 and 4 months. Since the last couple of orders I'm lucky if I make it to 3 months. At the 2 month mark we start noticing the water flow slowing down. There has been no change in our status or water usage to cause this change. Who knows, maybe it's filtering better so it gets full sooner, but the water doesn't taste any better than it used to, so who kno

Rated 3 out of 5 by from Filters Well Needs Frequent Replacment Sediment heavy water city water treated with chloramine was wreaking havok on my tankless water heater and appliances and drastically reduced water flow rate throughout my house. These issues are substantially improved with the Aquasana whole house chloramine filter.||However I have to replace the pre-filter every two weeks and the post-filter every 6 weeks or there is not enough water flow to

Rated 5 out of 5 by from Aquasana house filter The water filter I received was damaged in shipment. I called Aquasana and they sent a replacement filter with no hassles and no problems. I eventually used a plumber because I decided to go with copper pipes and fittings. The water has improved 100%. It tastes cleaner it feels smoother and I don't smell that chlorine odor that my water use to have. Overall a good system at a good price. I wi

Rated 4 out of 5 by from Great Product I purchased the whole house filtration system 3 years ago. We have really bad city water and it seems to have a lot of chlorine in the summer indicated by a strong odor. An interesting thing is that once we started using the filtration system our hair became softer and our skin not as dry. The only down side is that it doesn't get rid of fluoride (which is a toxic substance) but we added a r

Rated 1 out of 5 by from Dissappointed with Overall System We loved the promise of a non-sodium water system that would allow us to retain some of the mineral rich quality without subjecting ourselves to the questionable health effects of reverse osmosis. Unfortunately our water remains so rich in calcium manganese and magnesium that our dishwasher sinks and toilets are coated in a white deposit and at the advice or our Aquasana sales engineer we

Rated 5 out of 5 by from Aquasana saved the day. For 7 1-2 years we have thoroughly enjoyed and loved our Aquasana whole-house water filtration system. The water quality is outstanding for us our dog our lawn our cars and my koi pond and it tastes great! On top of that Aquasana provides amazing and immediate support if you ever have any problem at all. There is no better system of which I am aware...and the support is the best.

Rated 5 out of 5 by from To Easy! My wife and I got the system because we was tired of our water smelling and looking like sewer water. We noticed a immediate difference. The filters last about 2 months for us here in Midland Texas. They are simple to change. I would recommend this system to anyone with foul-suspect water.

User Q & A

How many microns is this filter? What are the dimensions?

Asked by: mudcity
Thank you for your interest in Aquasana! Our Whole Home pre filters have a 5 micron rating. We sell the filters as 10 inches and 20 inches long. The 10 and 20 inch pre filters both measure 2.5 inches across. The one you need with your whole home system will depend on the install kit you chose. Thank you, Aquasana Support
