They are so expensive that I only gave them four stars. I use them in my reverse osmosis filter and they seem to work fine. The water tastes great. I change them every six months. I should change them earlier, but I check the water with a rain gauge, and there is almost no sediment in my water, so I keep them for half a year. But I wish they weren't so expensive! Wow. But I need clean water and they work great.
