Reverse osmosis is a very effective filtration method, utilizing a semi-permeable membrane near final stages to remove nearly all Total Dissolved Solids from the water including micro-particulates and chemicals. The Tier1 reverse osmosis membrane can remove other potentially harmful chemicals like lead, chromium and nitrates from your drinking water. To ensure the best water for your household, replace your reverse osmosis membrane about every 24 months, depending on water usage and your local water quality.
