The US-UF-100-RM Tier1 Ultra-Filtration Hollow Fiber Drinking Water System Replacement Membrane is the replacement ultrafiltration membrane for the US-UF-100 system. The membrane is designed to reduce TDS in the water to create a more pleasant drinking experience. Total Dissolved Solids (TDS) are the total weight of all solids (minerals, salts, metals) that are dissolved in a given volume of water. The lower the TDS level in the water, the more efficiently your body's cells can use the water. Not only can TDS be unappealing visually and to taste but it can also pose danger to appliances and pipes as well as expose your body to more health risks. This filter helps reduce these dissolved particles and send the rejected water and contaminants down the waste water drain. It is recommended that you replace the membrane every 12 months, or 1,500 gallons for optimal performance. Tier1 is ready to protect every drop.
