Q) Does reverse osmosis remove parasites?A) The largest allowable pass through in a reverse osmosis membrane is 1/10,000th of a micron. Thesize suggested by the NSF to remove parasites is 1 micron. This makes the filtration quality of reverseosmosis 10,000 times better than the recommended value! Q) Where does the TDS go after the RO removes it?A) The RO membrane has the ability to clean itself. The particulates in the water are flushed down thedrain. This is why the RO membrane lasts so much longer than the other filters in the system. Q) How much water does this system waste?A) the typical waste to product ratio for a reverse osmosis system is 4 to 1 under the correct pressure.The ratio will change in favor of the product as the pressure increases. There are other ways to improvethe waste to product ratio as well. Please call us at (877) 803-7462 if...

De-ionization, (commonly referred to as DI), is a common process for producing ultra pure water. The DI filter is filled with resin beads, some with a negative charge and some with a positive charge. When you test your water with a TDS meter (total dissolved solids), it gives you a number that tells you the sum of the different contaminates in your water. All of these contaminates are either negatively or positively charged, so when they pass through the DI filter they are attracted to the oppositely charged resin beads. Since the DI filter has both negatively and positively charged resin beads it is able to remove 99% of the contaminates in your water. Reverse Osmosis (RO) is capable of removing 95-97% of all contaminates, so when the remaining 3-5% is passed through a DI filter you are effectively removing 99.9% of the contaminates. This quality of water is comparable to...
