My house water supply comes from a city water system that is based on river water and needs a low-micron filter at times to help remove those small particles. I have found these to be great when paired with a carbon filter or two in a home water system. Between the two, my water is clean and odorless all year long. Easy to maintain and change at different times of the year. Well worth the small price for a high-quality filter. Read more

I am on a well and have two water filters in series to get the dirt/sediment out. After 2 months the first filter shows significant collection of red dirt. The second has to be looked over closely to see any discoloration. I only change the second one yearly just because. It really could go longer. That itself speaks to the efficiency of these. One is doing the job. Laundry wise, the whites are as white as when we had city water. The price is a fraction of what they cost locally. Read more

Outperformed other filters that cost me twice the price. Excellent filter and I highly recommend it. Read more

Been using these a few years and always very satisfied with the filtration level. Doesn't affect pressure. Read more

Does not matter who makes them or how much they cost, you can find filters that cost more than these but they won’t work any better. Remember, these are just particulate filters and you’re going g to throw them away in a few. Months. So just buy these as they work as well as any and are less expensive. Read more

These 1 micron filters appear to be exactly the same dimensions as the Pentek filter designed for the Big Blue 10" housing. I use one as a secondary and final filter after a 20 micron (nominal) well water sand filter system. Over 6 months with 3 people, the well water stays crystal clear in my house. When I change out the old filter I see it's very stained, apparently from very fine rust-colored particles that get through the sand filter. I know the iron content of my well water is right at the aesthetic limit, so this makes sense. Read more
