    Ordered the dual stage and I absolutely LOVE this product! Water has a great taste and my stomach has settled. Love it!

    Ordered the ProMax countertop and there is a distinguishably different taste in the water. The old Chlorine taste just isn’t there after running the water through the ProMax filter. My mother absolutely loves it. When I asked her how the water tasted she replied “It tastes like water, like water should!” I feel refreshed after drinking a glass of water from the ProMax!!!

    We have used ProOne under counter filters now for about 6 years. I love mine and take my filtered water everywhere I go. I am sensitive to chemicals, and this filter does the job for me!

    Just bought one of the dual stage filters after using an aquasana countertop filter for years and WOW! The water from this is soooo much better lol. It is a bit more expensive but you also get more for your money in terms of filtration. I Can’t believe how much better the water tastes and how much better I feel! Mad at myself that I didn’t buy one of these years ago. Amazing filter!
