1st time install - help note
We used to have pretty old filters in and the flow was poor. New ones increased the flow by 5x. Regarding the install; the filter did not stay all the way pushed up into the housing. I put a penny at the bottom of the filter to keep it pressed tightly. There is no water flow if it's not snug. The little trick worked.

Glad I have this system
Our water has pesticides, lead, and way too much chlorine in it. It is basically undrinkable straight from the faucet. I am so happy that Aquasana has this under-the-sink option. I wish the replacement filters were a little less expensive, but they work; and I am grateful.

I am pleased with the triple filters
I am very happy with my Aquasana triple water filters. I have one in each of my sinks. I changed the filters myself after watching the video. The water tastes great and I feel confident that the filters are working well to clean the water. I can see the difference between the color of the old filters and the new ones. These filters are doing a great job.
