The Tier1 4-Stage Ultra-Filtration Hollow Fiber Drinking Water Filter System with Filter Change Set is a four stage under-sink filtration system with back up replacement filter set. The stages are sequenced to filter particles down by size so that they all together increase the longevity of the filtration system and each of the other replacement filters. The sequence is as follows, (stage 1) a 5 micron sediment pre-filter, (stage 2) carbon block pre-filter, (stage 3) a 1 micron sediment filter, and (stage 4) a hollow fiber ultrafiltration membrane post-filter. Together these filters are capable of reducing sediment, dirt, chlorine taste and odor, and a significant amount of total dissolved solids (TDS). The system features our innovative twist and lock filter change design to make filter changes easier than ever. The sediment filters should be replaced every 3 months, the carbon filter every 6 months, and the ultrafiltration membrane every 12 months. With the back up filter set you can have your first exchange of each filter type covered. Featuring a slim, compact design this filter installs easily under the sink and doesn't take up much space. This space saving design allows you to keep your usual items underneath the sink with ease. This system also comes with a stylish chrome faucet which goes well with most countertop and backsplash designs, to dispense the filtered water. Enjoy the clean crisp taste of filtered water with the Tier1 4-Stage Ultra-Filtration Hollow Fiber Drinking Water Filter System today!

4 Stages of Ultra Filtration

Stage 1: During stage one, water enters the sediment filter. The sediment filter reduces physical particles, such as sand, rust, silt, soil, and more!
Stage 2: Next the water goes through the carbon block filter. The carbon block filter reduces the taste and odor of chlorine.
Stage 3: After the water has been reduced of sediment and chlorine taste and odor it goes through another sediment filter to ensure most physical particles are remove.
Stage 4: During the final stage, the water goes through the membrane. The membrane reduces total dissolved solids (TDS). This stage is to ensure that your water is safe and ready for use at the quality you desire!
