I bought the new filters to replace the one I had in the machine when I bought it. When I went online I was not sure of the model number of the filter. I looked at the information that came with the machine and found nothing. Thinking that I probably knew which filter was the right one, I was ready to place the order but fortunately, had second thoughts and called the company. It was good that I did or I would have ordered the wrong filter. My only concern is how long the filter lasts. The ad says that it is goon for 350 gallons but the original filter did not last anywhere near that long. Still, we are happy with the machine.
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.
