As described

I wasn’t sure if the filters will be as described until I received them. They are what they described on website. Shipped and received very quickly with free shipping option. So far the first filter is working great.

Excellent Customer Service

By Man in 60s and over from Larkspur, CO on 1/22/2021 2:35:28 PM

We were sent filters that we did not order, which can happen because we are all human. What was remarkable was how quickly they corrected the mistake. We had the correct filters in hand 2 days later. Good job, All Filters!

Good, but

By Male in 60s and over from Everson , WA on 10/24/2022 6:40:20 PM

My well produces a high volume of sediment. My filtration system has 2 7525 and 3 2501 filters. The most recent filter changing showed that both 7525 filters had vertical splits about 1 foot long. Hopefully, this was a one-off occurrence.
