I purchased the iSpring RCS5T reverse osmosis water filter from Home Depot around January 2018 and just finally finished installing it. I am very satisfied with my filter since, it has been less than a month and I have already started to notice sediment accumulating in the see-through sediment filter housing! I use the filter for my pets also and have noticed that there water dispensers smell less like chlorine now! Although this particular model requires you to have a minimum of around 40 psi of water pressure from your incoming water line, the booster pump helps out a great deal and has risen the water pressure inside of my filter unit to 60 psi. Overall it is a great filter, very useful filter (can be used for drinking, cooking, pets, fish and aquariums), am satisfied with purchase. Would definitely recommend to anyone out there in need of a efficient water filter.Note: Installation may require user to possess basic plumbing skills and knowledge.
