Bidet Seat Ion Water Filters - Fits all bidets using a 1/2 inch water line

3 Pack of ion water filters for bidet seats. Extend the life of your electronic bidet toilet seat with an inline ion water filter. Ion filters soften water for better cleaning and remove impurities from the water source. Adding negative ions makes water clean faster with less surface tension. Ion filters are also designed to keep calcium (hard water) from building-up and capture large and small particulate matter. Ion filters are the best choice for most bidet seat installations. If you don't have hard water use a sediment filter instead. All filters have 1/2″ fittings, one male and one female and fit all bidet seats with 1/2″ water supply lines. Install the filter between the "T" connector and water hose leading to bidet seat. Change filters every six months.
