I am very happy with both purchases of the air and water filters. These have been on my to-do list to buy for quite some time and I finally decided on the Sans. I did a ton of research on which type of system would be best for our home and so far I am very happy! I do wish there was a way to connect a water line directly to the water filter, just because we use so much of it, but it is not an issue. I honestly can't believe we have been drinking Brita filtered water all these years! The air filter has been awesome so far as well. We have 2 dogs and 3 kids, so the house always has dirt, pollen, hair, etc. floating around. I have noticed a huge difference in the indoor air quality and no more stinky dog or shoe smells! Yay all around.
