  • Patent number: 11484386
    Abstract: A dental instrument water supply filter includes a hollow cylindrical body which bounds an interior area. The interior area houses a plurality of iodinated resin particles. A pair of water permeable discs are positioned in the interior area of the body at opposed axial ends. End caps close the interior area of the body at the respective opposed ends, and each end cap includes a respective removable fluid fitting. Water that is used in connection with the operation of a dental instrument is passed through the filter. The filter provides filtration and reduces microorganisms in the water that is passed therethrough and also releases ions into the water that are effective to reduce the growth of contaminants in the water lines to the instrument.

  • Patent number: 11376551
    Abstract: An Atmospheric Storage Tank (AST) system designed to be an alternative to the existing RO pressure storage tank that operates on water pipeline pressure. It eliminates the disadvantage of subjecting the RO system to back pressure on the feed water which reduces the efficiency of the system and also has a higher probability of leakage. When the AST system is installed below the faucet, a pumping gadget is required to pump the water. It is primarily designed, although not exclusively, to be used together with a zero waste reverse osmosis system.
