The PWF-ZR-1 Zerowater ZR-001 Comparable by Tier1 provides high quality filtered water with little to no dissolved solids. This replacement filter is easy to install and simply slides into the dispenser top to replace the existing filter. Reduction of total dissolved solids (TDS) means that you will be drinking water with virtually no leftover particles of common contaminants such as dirt, sediment, and more that produce unpleasant taste and unwanted contamination. This filter features a five-stage system to produce better water.

Stage 1: filter netting removes sediment from water such as dust and rust.
Stage 2: activated carbon sponge provides high filtration capacity to absorb many contaminants.
Stage 3: silver-loaded activated carbon effectively inhibits the growth of bacteria
Stage 4: mixed bed ion exchange resin lowers TDS from water.
Stage 5: high mesh netting removes ultra-fine particles.

When water provided by this filter reads 006 total dissolved solids, it is recommended to replace the filter in order to continue producing optimally filtered water. Enjoy better water today with the PWF-ZR-1 Zerowater ZR-001 Comparable by Tier1.
