I like using 1-micron particulate filtration in combination with an active charcoal filter. I have plumbed two of the white plastic filter containers together so the water must first pass through the 1-micron particulate filter before going to the charcoal filter. In combination with an adjustable pressure regulator, this has worked very well for both our motorhome and our trawler. Every drop of water coming into either of them is double-filtered, and the result is clean, clear water with no odor whatsoever. These 1-micron filters work very well. They arrived on time and were packed safely. I will certainly order them again.

Works well as expected

I bought these filters for sediment purposes. I have well water and wanted something to help with the sediment. They are working just as I wanted. I will have to replace mine more frequently because of the heavy sediment, but I am used to that issue. I will purchase these again.

I've been using these filters in our well supplied home for six years. Water quality has been excellent. I change the filters quarterly and they've trapped quite a bit of fine sediment / particles. Highly recommend this product.
