The process our salt-free water softener media use water flow to naturally prevent limescale build up. The process takes hard water (calcium and magnesium) and transforms the ions into microscopic nanocrystals. This suspends the particles so that it cannot “stick” or cause scale while the water travels through. FilterSmart Whole House Salt-Free Softener does not add anything or remove anything from the water, retaining the important naturally occurring minerals, especially calcium and magnesium.
Salt-using softeners must be regularly recharged by adding more salt and back-flushing with fresh water, which is costly, inconvenient, corrosive to pipes and water heaters, harmful to the environment and wasteful of a precious resource.
Salt-free water softeners have been found to be effective in preventing limescale. Unlike salt-based softeners, FilterSmart Salt-Free Water Softener won’t demineralize your water by chemically removing minerals replaced by sodium nor will it put excess salt waste or chemicals into our environment. All this while protecting your home's plumbing, extending the life of your washing machine, water heater, dishwasher and other appliances.
Stage 1. The sediment prefilter reduces sediment rust and debri in your water
Stage 2. Our salt free media needs only seconds of contact time to change the crystallized structure of the water, suspending the particles and preventing hard water buildup.

Our mineral tanks are built out of USA-made high-spun fiberglass, and they’re certified for safety. We offer a lifetime guarantee against manufacturer defects. Unfortunately, not all tanks on the market are made to such standards. The tanks are protected by a premium stainless steel cover.
Yes. However it does not remove iron, hydrogen sulfide or manganese.
The carbon media comes with a 5 year or 1,000,000 gallon guarantee. We guarantee the carbon reducing chlorine to undetectable levels for that period. When the carbon media needs to be replaced simply, order a replacement bag of carbon, dump out the expired media, and refill the tanks with new media. Other companies require a whole new tank purchase. With our reusable tanks we save our customers money in the long run.
The sediment pre-filters (inside the big blue filter) need to be replaced every 8-10 months. This can be done by any homeowner.
No. If correctly installed, our systems do not change or drop the water pressure.
Anyone with basic plumbing skills can easily install our systems. If you don’t know someone with basic plumbing skills, any local plumber will have no problem with the installation. If you need help finding a plumber, try Angie's List or Home Advisor for a list of local plumbers in your area.
Filtersmart whole house inline water filters are installed on the main water line at the home’s point of entry. The point of entry (POE) differs from house to house, but it’s usually either in the garage or outside – right by the water shut-off valve. Your local plumber will determine the point of entry and, by extension, the best point of installation. You also may have an existing water softener loop where the system would be installed, but virtually any plumber will be able to determine the best place to install the system.
