But does it REALLY cost more? Have a look at what the Fluoride recuction (Activated Alumina) replaceable cartridge type filter is paired up with. Most competitor systems couple the Fluoride recudction filter with another replaceable cartridge type filter. Even if that replaceable cartridge is a GAC-KDF (vastly superior to an all-GAC filter), it can only be rated for 12,000 gallons of service life -- about ONE THIRD the service life of the US4 filter (35,000 gallons) we pair up with the Fluoride filter. And we checked our competitors for the lowest price on replacement GAC-KDF filter cartridges and found that WE actually sell them for less than anyone else we could find -- $41.25. So, in order to get the service equivalent of one of our US4 filters (at $185 for the filter) you'd need to buy two more GAC-KDF replacement carts for $41.25 x 2 = $82.50. Add that $82.50 to the original cost of the competitor's Fluoride/GAC-KDF combo filter and see for yourself which is the most economical. If you've already done that math, you know you're already in the right place, for the best deal, right here.

Note: Maximum recommended flow rate is reduced to 0.25 GPM. If fluoride reduction/removal is a critical concern for you, you may wish to consider Reverse Osmosis as the more appropriate water treatment technology. Fluoride reducing Activated Alumina cartridges should be replaced approximately every 1,000 gallons (presumes average 4 ppm fluoride in incoming tap water).
