Great deal, great sevice!

By Man in 60s and over from Albrightsville, PA on 6/14/2020 8:06:21PM

Excellent filters for a great price. Pentek / Hydronix / SpiroPure filters all have the same composition & same specs but drastically different prices. I have found that using either Hydronix or SpiroPure has led to no difference in my water testing. Why pay 20 to 25 dollars for a PenTek when you can get the same for $10.00 to $11.00 in a SpiroPure. BTW: When I first had my system installed, I was told that to buy from the company who installed my system, it was $60 for 1 filter!! I obviously found them cheaper by buying from a company like AllFilters but then discovered the Hydronix and SpiroPure brands. No I change my filters once every 3 months. We have high iron here and as I said, these work wonderfully.

Good quality and on time delivery.

By Male in 60s and over from Rainier , WA on 7/30/2024 7:40:30AM

I've been using theses filters for about 10 years and they are of excellent quality, depending on the amount of sediment and tannens in your well water, they do last close to two months.

Excellent filter

By Female in 60s and over from Pollock, ID on 5/26/2023 8:13:42AM

We have water that contains lots of iron. These filters are great at removing the iron in conjunction with a water softener.
