Q:

How do you make a fluoride filter?

A:

Quick Answer

The most effective way to remove fluoride from the water at home is with a reverse osmosis filter. To make a portable reverse osmosis filtration system, buy a filter set, install it under your sink and flush the filter with water. Making a fluoride filter takes roughly 30 minutes and requires a reverse osmosis filter set and needle nose pliers. You may need a drill, an adaptor and gaskets for your faucet.

  1. Choose the filter

    NSF and EPA are certified as producing high quality reverse osmosis filters. Choose one of the filter sets that first pushes water through a pre-filter where large molecules are removed before sending it through the selective reverse osmosis membrane. The membrane removes the fluoride.

  2. Attach the filter

    Start by unscrewing the aerator from your faucet. Select the aerator that came with your filter kit, and attach this to the faucet. If necessary, use an adaptor and gasket to fit the faucet, which might be necessary with custom faucets.

  3. Set up the reverse osmosis filter

    Depending on the filter kit you bought, the filter itself may be small enough to stay on the counter or it may need to go under the sink. If it goes under the sink, drill a hole large enough for the hose near the faucet. Insert the hose that came with the filter into the spout housing on the aerator.

  4. Assemble the filter

    Unscrew the connector fittings from the top of the filter, and remove the caps. Use the needle nose pliers to insert the membrane into the socket, being careful not to tear it. Connect it to the hose. Insert the other cartridges in the appropriate sockets. Screw all caps back on, and attach the hose to the spout housing.

  5. Flush the system

    Turn your cold water tap on, and flush at least four gallons of water through the system. This rinses out the filter.
