A whole house reverse osmosis system is a water filtration system that filters the entirety of your home’s water through a reverse osmosis membrane. A whole house reverse osmosis system is installed at the point where water enters your home. Every drop of water entering your household plumbing is treated by the reverse osmosis membrane, from your drinking water at your kitchen sink to the water you use to shave, shower, and flush your toilets. Whole house reverse osmosis (RO) systems ensure that your entire home is free from any traces of water hardness, salts, chemicals, and TDS. The microscopic pores on the semipermeable membrane of the RO system can eliminate over 98% of dissolved organic and inorganic matter. The water produced by reverse osmosis is almost unparalleled in its purity, and it is a more cost-effective method of purification compared to deionization or distillation. While reverse osmosis is commonly used for residential point-of-use drinking water, those with extremely challenging water conditions install a whole house RO system to provide them exceptional water quality throughout their home.
Reverse osmosis removes a host of contaminants, like chromium, uranium, copper, mercury, arsenic, boron, silver, lead, sodium, and nitrates. Many of these can pose health risks in elevated quantities, and there are limited filtration methods effective at eliminating these all at once. While an under-sink RO system is ideal for providing purified water at a single faucet, sometimes water presents challenges that can affect your whole home. If your water source is compromised by toxic levels of chemicals and metals, it can be wise to eliminate these from every faucet in your home. There are some cases where water you brush your teeth with, bathe your children in, and use to cook and clean should all be purified by reverse osmosis.
