Product review (1 stars): It causes water to have a chemical/medicinal taste.
I bought this brand before and it worked fine. They aren't this time. The water had a chemical/medicinal taste that I couldn't get rid of. At first, I tried to flush it by dumping as much as 5 gallons, the taste stayed. I took the filter out and boiled it in water twice. The taste stayed. I do not recommend it. I ended up buying from somewhere else and it works.
