"Great experience ordering replacement filters for my US Water Systems whole house filtration setup. Fast Delivery as well. Only Zonk I give them is not being able to ship a 3 pack O-ring for less than almost 15 dollars in my order which was shipping free since the filters were on a recurring delivery program."

"I use my Limeblaster filter system to protect my Tankless Hot Water system and copper piping throughout the house. It’s made annual maintenance of the hot water system very easy and has kept that system in excellent condition. I highly recommend the Limeblaster Filter System if you have either copper pipes or a tankless system in your home."

"We live in an environmentally sensitive area in NW Michigan. We're on well water, and it's at 200+ in hardness. We wanted to fight scale and mineral buildup but are trying to avoid a softener and the excess salt to the environment. We installed the limeblaster on the hot water side of our plumbing alone about 3 years ago, and I do think it has made a noticeable difference. As we have it on the hot water only it extends its life a bit, and feel it has been worth the filter cost. It will NOT do the job of an actual water softener, but it does improve the situation."

"Absolutely fantastic product, just what the doctor ordered. The company that had I ordered my filters & installed my water filter system had closed their doors leaving no forwarding help in obtaining new filters and up to the plate stepped US Water Systems to hit a home run by providing me with replacement water filters. Outstanding people to work with."
