Ordered water filter replacements for our Aquasana, countertop water filter. We've used it several times a day for years and it's a life saver. Wish we had room for a whole house filter.
The first filter that came with unit I was only able to get approximately 90 gals before red light came on. I am on 2nd filter and will be able to get a better idea if it is cost worthy to buy filters. Have not used filters just recently purchased. Cannot make recommendation at this time.
