Rated 2 out of 5 by from Substitute filter? Ordered a couple of these and Aquasana sent me filters labeled as Flow-Max. Looking through the internet I found sites that sell model FM-0.35-975 for almost half the price.||I bought these because the current post filter on my unit is getting very dark only after 6 weeks of use even though the pre-filter is still mostly clear. That's telling me that the first two stages of the Rhino unit aren'

Rated 5 out of 5 by from Great product This is a great system. I would add one thing to your upgrade package A Gallon meter. nothing fancy I check out a couple other water treatment system (salt yuck) Most of them has a meter of some sort built in that only let the unit regenerate when either the max gallons have been used or low water pressure. I installed my own gallon meter and a chart. Now it's as easy as looking at the meter to s

Rated 4 out of 5 by from So far so good I purchased the whole house filtration system last year. It was for a water well that had a high iron content. It worked & gave me clean clear water but my water quality from my well was so bad that I was having to change the filters a couple of times a week. So I finally gave up on my well and connected to the city water supply. The chlorine & taste was bad, but the filtration system seems to be

Rated 1 out of 5 by from Do not last; clothing discolored Agree with many prior reviewers in concluding that these filters are expensive and only last 3 weeks; have had limited success washing them and reusing them as they do not clean easily. I also agree that it seems this filter is doing most of the filtering for the entire system. I have the entire whole house Well system minus the UV and, on the positive side, the Sulfur smell is much improved; th

Rated 3 out of 5 by from doest not last a long time-too expensive depending on the water quality (which for me its well water which its not good quality) the filter lasts about 1 month and a half tops before the water starts smelling again like rust & items that use the water start getting stained with the rust color again (toilet-sinks-washing machines-shower tubs etc...) I live in a unincorporated area which only has well water for each house and we have the

Rated 4 out of 5 by from RINO POST FILTER I use a 1 micron pre-filter (before the RINO tank). Change about the same time as the 5 micron. This helps extend the life of the RINO and also the expensive post filter. My last post filter lasted about 1-1.5 yrs. The 1 micron pre-filters can be bought in bulk (12) for about the same price as the 5 micron, but definitely helps with the taste and extended life of the RINO and post filter.

Rated 5 out of 5 by from Top product and service This is my second Aquasana Whole House Filtration system. It provides my family peace of mind because the filtered water that can only be beneficial to one's health. For DIY, the installation is a bit involved but do-able. It requires some plumbing, initial flushing of the filters, and transporting the heavy units to the installation site. A professional would do it more easily.

Rated 1 out of 5 by from Other reviews are correct I am also so disappointed. The other reviews are referencing well water so I thought that I would be okay in Chicago. Turns out even with lakewater the filter only lasts maximum of two months. It bothers me a lot that I have to pay $25-$30 every two months as opposed to every year. Aquasana should back their filters and charge half of what they charge.

Rated 5 out of 5 by from Excellent All over the house filtration pre and post filter. We have filthy water and it is so much better now does not smell like a swimming pool in the bathrooms. Water is soft and tastes good especially with reverse osmosis in the kitchen which we could not install until the water is filtered becuase our city water is ohhhhh soooooo bad!!!!
