Filters Out Harmful Contaminants

Remove up to 99.6% of chlorine and other contaminants with our whole house water filter system. It has multiple lines of defense against harmful chemicals and pollutants, including:

Taste, Odor, Chlorine, Chloramine, Haloacetic Acids, MTBE & THM's, Herbicides, Pesticides, and many others.

Softer Skin & Healthier Hair

Eliminate contaminants in the water that can be harmful to your body. By filtering chemicals such as chlorine and chloramine, you can avoid the drying effects of chemicals, promoting softer skin and healthier hair.

Why Use a Water Softener

The mineral build-up, or scale, can occur in plumbing and household appliances when your water is hard. Solid deposits of calcium carbonate can form when hard water is heated. This scale can reduce the life of appliances, raise the cost of heating your water and clog pipes. Long-term movement of hard water through a pipe results in scale buildup. This can gradually close up the pipe and lower your water pressure.

Prevent & Reverse Hardness Build-up

Extend the life of your plumbing and household appliances by preventing and reversing scale build-up. OnliSoft Salt-Free water treatment system naturally neutralizes hardness minerals into inactive microscopic crystal particles without salt or any other harsh chemicals.

PPH Anti-Scale Sediment Filter

Designed to filter out sand, silt, clay, and any other sediment down to 5 microns while neutralizing the hardness with polyphosphate media certified to NSF/ANSI/CAN 60 and Scale reduction performance IAPMO/ANSI Z601 standard.

This 5-micron sediment filter is the largest size available for maximum flow rates and longevity. It's 20 inches high and 4.5 inches wide.

High-Quality Filter Housing with Bacteriostatic Technology will provide years of pain-free filter replacements.

Certified Carbon Cartridge

Activated carbon block filters for chlorine, chloramine, PFAS, taste, and odor reduction.

Excellent chemical contaminant reduction, high adsorptive capacity, and efficiency.
