About this item

  • COMPATIBLE REPLACEMENT MODELS – Designed to fit standard 1 Micron 10 x 4.5 sediment water filter is a replacement for Pentair DGD-2501, 155359-43, SDC-45-1001, P1-10BB, FPMB-BB1-10, and SDF-45-1001; fits most 10” x 4.5” whole house filter housings.
  • 1 MICRON DEPTH SEDIMENT FILTRATION – Spun wound polypropylene construction captures fine particles throughout the cartridge depth, helping reduce rust, sand, silt, dirt, and scale commonly present in well water and municipal water systems.
  • FINE SEDIMENT POLISHING DESIGN – The graded density depth structure traps larger debris on the outer layers while finer particles are captured deeper inside, making 1 micron filtration ideal for sediment polishing ahead of downstream filters.
  • SERVICE LIFE VARIES BY WATER CONDITIONS – Replacement frequency depends on sediment levels, water quality, and micron rating; finer filters capture smaller particles more quickly, so monitoring flow or pressure changes helps determine when cartridge replacement is needed.
  • IDEAL WHOLE HOUSE PRE-FILTER – Commonly installed as a first-stage or entry-point sediment filter to help protect plumbing, appliances, water softeners, and carbon filters from fine sediment buildup and premature wear.

★★★★★

Perfect pre-stage water filter.

LarryB—January 1, 2026✓ Verified purchase

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

Work very effectively and a great price

Ben H—February 8, 2025✓ Verified purchase

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

Fantastic Product

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

String filters are…string filters

Purple Griffon—February 11, 2024✓ Verified purchase

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

Fits a Big Blue housing fine. Lasts 6 months installed after a 20 micron sand filter.

Chas—May 14, 2025✓ Verified purchase

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
