Patent number: 11339060Abstract: An apparatus provides a water bottle mouthpiece attachment which can filter microplastics and other contaminant substances from bottles, particularly disposable plastic water bottles. The filter of the apparatus includes a filter housing that is attached to a cap that fits inside a common plastic bottle. Soft rubber rings, tapering from to radially larger on the top to radially smaller on the bottom in a generally conical fashion, ensure a watertight fit to the inside opening of any drinking bottle. A friction closing/opening spout at the top of the filter enables selective opening of the bottle and prevents accidental spillage of bottle contents. The filter housing is also offset from the center, giving space to an air valve that allows air to enter the bottle without disturbing the flow of water from the bottle, thus providing optimal lamellar flow without allowing fluid to escape through the air valve during consumption.Type: GrantFiled: February 25, 2021Date of Patent: May 24, 2022Inventor: Nils Nedrelid

Patent number: 11286191Abstract: An apparatus for filtering water has a valve head and a filtration/purification canister removably mountable thereon. Connecting the canister to the valve head automatically opens a check valve in the valve head to permit water to flow from the valve head into and through the canister, and then back to and through the valve head to an outlet port. Disconnecting the canister from the valve head automatically closes the check valve, stopping the flow of water. A bypass valve is provided in the valve head to permit a sanitizing solution to flow through the valve head and along the lines of the water distribution system to sanitize the system, while bypassing the canister. The outlet port may be directly connected to an appliance that uses water, to eliminate possible contamination that may occur when water is brought indirectly from the outlet port to the appliance instead.Type: GrantFiled: December 18, 2017Date of Patent: March 29, 2022Assignee: General Ecology, Inc.Inventors: Richard T.
