While searching for a 10 micron reverse osmosis separator I found these pre-filters. Pros: + Reasonable price of $8.19 (2 pack) with free shipping when I bought them from MaxWarehouse + Pretty good customer reviews of the product. + Advertised 10 micron filtration. + Advertised - Size: 9.75"H x 2.5"W x 2.5"D. + Advertised - Reduces fine sand, silt and rust particles. + Advertised - Imported β Made in China on the label Cons :- Actual diameter is smaller than advertised 3/8" thick! comes from unopened packaging.- Made in China β For those who prefer to buy products made in the USA. Final note: βͺ I have chosen not to use these filters as the installation is not to my liking and they have a strong chemical odor which according to some revators are carried over into filtered water. βͺ I'm going to ditch these filters and use these: iSpring FP110X2 10 Micron 10" x 2.5" Universal Sediment Filter Cartridges, 15,000 Gallon, Multi-Layer, NSF Certified (2 Packs)
