The 5-Stage Reverse Osmosis System with Brushed Nickel Faucet by Tier1 uses 5 stages of filtration to deliver up to 50 gallons of filtered water per day. The 5 stages include a first stage sediment filter, to remove particular contaminants, followed by a carbon filter for chlorine reduction, and a third stage sediment filter to remove any remaining contaminants, prolonging the health and performance of your system. The 4th stage is our Tier1 RO membrane which captures the nastier contaminants like barium, cadmium, chromium (III and VI), copper, fluoride, lead, mercury, nitrates, nitrites, radium, selenium, and total dissolved solids (TDS). Then the water is transferred to the storage tank so you have plenty of filtered water on demand. The 5th stage carbon block filter is placed just before the water comes out of the tap, to reduce any residual tastes, odors, or impurities polishing the water just before it enters your glass. Order today and enjoy clean, great tasting water right from your tap for cooking, coffee and tea, all while saving yourself the money and hassle of buying costly bottled water. Experience more of life's pleasures, experience Tier1 water.

Why use Reverse Osmosis?

Reverse Osmosis is considered one of the most all-around effective filtration methods. Utilizing semi-permeable membranes with holes just 0.001 microns in size, reverse osmosis filters are even able to remove dissolved solids from the water. This means that the reverse osmosis membrane can trap many types of contaminants that standard sediment or carbon filters cannot. Contaminants such as nitrates, arsenic, fluoride, and chromium are examples of contaminants where traditional filtration can fall short. Reverse osmosis filtration on the other hand can remove up to 99% of over 1000 contaminants. If you are concerned about the amount of total dissolved solids in your water, or are looking to reduce a particular chemical in your water, Reverse Osmosis is most likely the best filtration option for you.
