This Watts Premier RO-Pure 4-Stage Reverse Osmosis System is one of the best RO filters available on the market. If you want to improve the quality of the drinking water, this 4-Stage reverse is your best choice.
Stage 1: 5 micron sediment filter
Stage 1 is a 5 micron sediment filter, which is used to filter particulate matter, such as rust, dirt and silt. These matters not only can affect the taste of your water but also the appearance of your water. So stages1 is a basic filtering.
Stage2: 5 micron carbon block filter
Stage 2 is a 5 micron carbon block filter which can reduce much more chlorine and other materials. These materials cause the bad taste and odors. Chlorine exists widely in the water, because when producing tap water, we use Chlorine to disinfect water. Chlorine will send out a pungent smell. In this stage, bad odor will disappear.
Stage 3: RO Membrane
Stage 3 is the main step. In this stage, the RO Membrane is used. This 50 gallon per day semi permeable membrane can effectively reduce TDS. What is TDS? TDS is totally dissolved solids, such as Sodium, Lead, Chromium, Arsenic, Radium, Percolate, Copper etc. These contaminants are harmful for our healthy. They are dissolved in the water. Also the RO Membrane can effectively remove over 99.95% cysts, such as Cryptosporidium and Giardia. The larger production membrane also means this Watts Premier RO-Pure 4-Stage System is designed to reduce Nitrites and Nitrates in the water. We know if you take much more Nitrites and Nitrates, you are more prone to cancer. One thing is important that this reverse osmosis water filtration system need at least a 40 PSI incoming water pressure to operate.
Stage 4: Carbon filter
Stage 4 is a Carbon filter with high quality. This is also called a post-filter. The filtered water will pass through the membrane and finally enters the storage tank. If you need to drink water, the water will leave the storage tank and pass through the stage 4 Carbon filter on its way to the faucet.
