Reverse Osmosis

Reverse osmosis systems are one of the most cost-effective and simple ways to get pure drinking water without the expensive water bottles. These systems use a membrane filter system to remove a wide range of impurities, giving you great tasting water from a small package. These are one of the most affordable systems for those on a budget.

Activated Carbon

Activated carbon systems use a specialized filter made of activated carbon to remove a wide range of impurities. Activated carbon use a process called “adsorption” wherein the carbon itself absorbs the impurities in your water like a sponge. These filtration systems are often combined with other purification methods to remove substances that may not chemically react with carbon.

Ion Exchange

Water softener and deionizer systems use an ion exchange filtration method to remove hard water qualities from your home’s water. In these systems, water percolates through a filter of spherical resin beads. These resin beads exchange ions with materials in the water, which in turn removes inorganic materials from your water and gives it “softer” qualities. 


Mechanical filters are water filtration systems that use a variety of different media to remove a wide range of water problems. Many of these mechanical systems are built to handle high water capacities, enabling your entire home to enjoy purified water. Plus, by combining different filtration technologies and processes, they can often successfully eliminate a huge range of different water inclusions.

Ultraviolet Filters

Ultraviolet filters blast the water that enters your home with concentrated ultraviolet light. This process neutralizes common organic inclusions, such as bacteria, fungi, viruses, and other microbe organisms that are sometimes found in the public water supply. These purifiers typically do require additional power to operate the ultraviolet light, but the total usage is still fairly low as most UV lights are incredibly efficient.
