Where can I buy a reverse osmosis filter for my kitchen sink?

I am excited to present you with this osmosis filter. The advantages of the Tap Master ULTRA with UV sterilization UV is more effective against viruses than chlorine, without the use of chemicals or their byproducts. No change in taste, odor, pH, conductivity or general chemistry of the water. Immediate & automatic treatment process Annual lamp replacement, no moving parts to wear out. Audible Alert indicates need to replace UV filter How does UV Disinfection work? After the water has been filtered down to a sub-micron level, it then enters an ultraviolet sterilization chamber where any viruses, bacteria, mold, and other living microorganisms are bombarded with special, intense light of a specific wavelength (254 um). The UV light penetrates the cell walls of the organisms and attacks their DNA structure leaving the organism dead or unable to reproduce - effectively neutralized. UV technology is recognized by the EPA as one of four approved methods of sterilizing water, and is preferable over the other three methods - chlorine, iodine, and distillation - due to its instantaneous effect and the fact that it does not leave any residual chemicals in the water. The Tap Master UV module operates for a full year at 32,000-microwatt seconds/cm. Factors Affecting UV The effectiveness of a UV system in eliminating microbiological contamination is directly dependent on the physical qualities and/or clarity of your water supply. Suspended Solids or particulate matter can cause a shielding problem in which a microbe may pass through the UV filter without actually having any direct UV penetration. The filters in Tap Master can remove up to 99% of suspended solids and particulate matter. Please change your filters on schedule. Iron/Manganese will cause staining on the quartz sleeve that houses the UV bulb, at levels as low as 0.3 PPM of iron and 0.05 PPM of manganese. In this case, we recommend the Tap Master ULTRA, which includes advanced iron filtration.

The second osmosis filter I highly recommend because. The system is easy to install and simple to operate. It uses no electricity and the impurities removed through the reverse osmosis process are flushed down the drain. The processed water is conveniently stored in a 3-gallon pressurized tank that is small enough to fit neatly under your sink.

The MP750PlusRO system includes multiple pre-filters, RO membrane, and Multi-Pure®’s MP750SB as a post-filter, providing you the highest quality water possible. The pre-filter component provides 5 micron filtration to remove large particulate matter and extend the life of the reverse osmosis membrane. The post-filter provides sub-micron (0.5 micron) filtration to ensure that the water you drink is healthy and delicious. Enjoy!

Depending on the system you have, I did find GE Profile Smartwater they last about 6 months or 900 gallons they start at about $40. Aqua-Safe is the industry leader in top-of-the-line water purification systems. The premium Maximus II system is affordable and provides worry-free, highly effective water filtration you can trust. In fact, it is equal or better in quality to Aquafina? (Pepsi) and Dasani? (The Coca-Cola Company).
