How it works

How it works

2 Stages of Filtration

  • Stage 1. A sediment pre-filter with a 5-micron rating efficiently captures rust and debris from water sources. Its design prevents these larger particles from causing clogs or damage to plumbing and appliances. Replace the pre filter inside the blue housing every 8-10 months.
  • Stage 2. Our salt-free water softener works by altering the behavior of minerals like calcium and magnesium in water. It uses a special media to catalyze the formation of microscopic crystals, which reduces the minerals' ability to attach to surfaces and form scale, effectively preventing hard water buildup without removing the minerals from the water.

Salt free water conditioning for a limescale free home

Our salt-free water softener prevents hard water buildup without removing minerals from the water. This can extend the lifespan of pipes, faucets, and water heaters, and prevent limescale buildup in appliances. It also doesn't add sodium to the water. Upgrade to a healthier less costly water treatment system that is also maintenance free!

Why Filtersmart?

Protect plumbing and appliances

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.

Clean, pristine water for softer skin and hair

Water conditioning can help to make your skin and hair feel softer and smoother. Hard water, which contains high levels of minerals like calcium and magnesium, can leave a residue on your skin and hair that makes them feel dry and rough. Water conditioning systems, such as salt-free water softeners can reduce these minerals from the water, resulting in softer and smoother skin and hair.

Spot free kitchens and baths

Salt-free water softeners have been found to be effective in preventing limescale. Unlike saltbased 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.

Salt-free equals maintenance free

Never carry heavy bags of salt again! Changing
out the sediment pre-filter every 8-10 months is
the only maintenance required. FilterSmart upflow systems require no electricity to drain or salt
replacements.

Whole House Water Filter FAQ

How Large Are The Tanks?

Our 1-3 Bath 12 GPM systems uses 9 x 48” tanks and sits about 52 inches tall, including the valve head. The 4-6 Bath 15 GPM system uses 10x54” tanks and sits about 58 inches tall. For single tanks, we recommend 20x10” space. For our combos, we recommend a 30x10” space.

What Are The Tanks Made Out Of?

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.

If I Get The Filter, Can I Add The Water Softener Later?

Yes. You can get our whole house water filter system, and then, if you’re unsure whether you need to treat the hard water, just add our salt free softener to make a combination system later.

How Does Activated Carbon Work?

Our tanks come pre-loaded with granular activated carbon (GAC). To remove contaminant impurities, activated carbon works through the process of adsorption. Each particle, or granule, of carbon provides a large surface area, or pore structure, allowing contaminants the maximum possible exposure to the active sites within the filter media. One gram of activated carbon has a surface area in excess of 3,000 square meters (32,000 square feet). The large surface structure, plus the prolonged contact time, maximizes water filtering capacity.

Does The System Work For Well Water?

Yes. However it does not remove iron, hydrogen sulfide or manganese. 

How Often Does The Media Inside The Tank Need To Be Replaced?

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.

How Often Do I Change Out The Pre-filter?

The sediment pre-filters (inside the big blue filter) need to be replaced every 8-10 months. This can be done by any homeowner.

Is There A Reduction In Water Pressure?

No. If correctly installed, our systems do not change or drop the water pressure.

Where Is The System Installed?

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.

"I went with the salt free option and i am happy with it. No more white residue in the shower and faucets look much better and flow properly now without hard water clogging everything up. Im hoping this will really help my tankless water heater that seems to not like my hard socal water."
