Works Fine

Customerβ€”April 10, 2025βœ“ Verified purchase

Works fine in my Whole House 20 inch Pentek Big Blue Filter Housing. I've used the Pentek EM-20BB cartridges for the last 10+ years but thought I'd try this Geekpure filter which was 35% less expensive. At a flow rate of 8 GPM there is a 2 psi pressure drop which is the same as the Pentek filters upon initial installation. The old filter I replaced was at a 3-4 psi drop at the same flow rate after being in service a year. I have pressure gauges installed ahead of and after the filter to monitor pressure drop. Feed water tested 1.3 ppm Free Chlorine and 0.1 ppm (or less) after the filter at that 8 GPM flow rate. We'll see how it goes. Read more

Helps sulfur smell and easy install.

EmJayβ€”January 29, 2026βœ“ Verified purchase

Bought cheaper than the one sold locally. Saved over $10. Needed to replace my old one that lasted from Nov - Jan on a house with a well that smells like sulfur. Made a big difference. Didnt want to spend a lot of $ on a sulfur removal treatment but this is a good alternative. I would continuously buy this and from this company. This will last for another 3 months. Read more

It's what I was looking for!

Book Gluttonβ€”October 10, 2019βœ“ Verified purchase

In the past I have used the Pentek FloPlus filters. They go for $79 now on Amazon. Each time I replace a filter, I look for new alternatives. This time I found the Geekpure. It's close to 1/3 the price I was paying. It came with 5-star reviews. Why not! I know that a new filter is needed when the pressure drops. I replaced the old with the Geekpure. It's a 5 Micron carbon like the rest. The pressure was back. No smell of chlorine or anything else. Great tasting water. That's all I'm looking for. Now, we'll see how long it lasts. That's the final test. Read more
