Reverse Osmosis Systems

Reverse Osmosis Systems use a process that reverses the flow of water in a natural process of osmosis so that water passes from a more concentrated solution to a more dilute solution through a semi-permeable membrane. Pre- and post-filters are often incorporated along with the reverse osmosis membrane itself.

A reverse osmosis filter has a pore size of approximately 0.0001 micron.

Reverse Osmosis Systems have a very high effectiveness in removing protozoa (for example, Cryptosporidium, Giardia);

Reverse Osmosis Systems have a very high effectiveness in removing bacteria (for example, Campylobacter, Salmonella, Shigella, E. coli);

Reverse Osmosis Systems have a very high effectiveness in removing viruses (for example, Enteric, Hepatitis A, Norovirus, Rotavirus);

Reverse Osmosis Systems will remove common chemical contaminants (metal ions, aqueous salts), including sodium, chloride, copper, chromium, and lead; may reduce arsenic, fluoride, radium, sulfate, calcium, magnesium, potassium, nitrate, and phosphorous.

How does carbon filtration work?

FilterSmart has partnered with Jacobi Carbons, the world's largest manufacturer of coconut shell-based activated carbon. Our carbon is an acid washed high purity high activity granular activated carbon manufactured by steam activation from carefully select coconut shells.

Adsorption pores are the only regions within an active carbon particle with sufficient adsorption forces to adsorb impurities.

Together with Jacobi we have blended the world's best-activated coconut shell carbon in the industry to create the industry best house water filter.

Clean, pristine water and softer skin and hair!

Shower and bathe is water free from chlorine and other harmful chemicals. While ingesting chlorine and chloramine treated water has negative health effects, studies show the majority of our exposure to chlorine is through absorbing chemicals during showers and baths. With the removal of drying agents you will immediately feel the benefit of filtered water at every tap and bath in your home.

4 Stages of Filtration

Stage 1.A 5 micron sediment pre filter captures rust sediment and debri

Stage 2. Using Votrex technology our uplow design tank mixes upward through the fiberglass mineral tank.

Stage 3 & 4. Our proprietary Coconut shell based carbon mix removes maximum contaminants and removal rates.

Whole House Water Filter FAQ

z 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.

z 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.

z If I Get The Filter, Can I Add The Water Softener Later?
z How Does Activated Carbon Work?
z Does The System Work For Well Water?

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

z 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.

z 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.

z Is There A Reduction In Water Pressure?

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

z Who Installs The System?

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.

z 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.

z Can The System Be Installed Outside?
