What Types of Water Treatment & Filtration Systems Are Available?

Whole home water treatment systems improve water quality and extend the life of your plumbing. Furthermore, purified water is healthier for your family and safer for the environment.

Improve your home’s water quality and get the best in water filtration system installation from the experts at Mainstream. Our plumbers will help you decide which type of water filtration system is best for your home.

Carbon Filter Water Filtration

Carbon filters help treat water with odors or bad flavor by using activated carbon. Water flows through tiny pieces of carbon which absorb contaminants and help in limiting the strong taste of chlorine and other chemicals used in water treatment plants.

Reverse Osmosis Water Filtration

Reverse osmosis ranges from simple purification to a more complex, multi-step impurity removal process. In both cases, it is one of the more efficient water filtration systems at removing impurities, leaving behind only beneficial minerals by forcing the water through a permeable film at the molecular level. Call our water treatment experts today to see if a reverse osmosis water filter is best for your home.

UV Water Filtration

These water treatment systems use UV light to treat your water, killing off bacteria that may be in your water supply. This is a popular choice for the environmentally conscious, as it does not require any chemicals or produce additional heat.

No matter your water quality needs, our water treatment and filtration installation experts can help you choose the best water treatment solution for your home.
