If you have a 3-canister CHLORAMINE FLUORIDE PLUS unit from us, this is the bundle of the THREE replacement filters you need.
CHANGE THIS SET OF THREE ONCE A YEAR.
CHANGE THE FLUORIDE FILTER EVERY 6 MONTHS. (Link to fluoride cartridge)
NEW Cartridge Casings FOR IMPROVED DURABILITY. NEW CARTRIDGES WILL LOOK A LITTLE DIFFERENT THAN YOUR OLD ONES. PHOTOS OF REPLACEMENT SETS NOT YET UPDATED. See the individual photos to see the new housings.
THIS IS THE ORDER YOUR FILTERS GO IN:
The first cartridge (CR-1) as the water flows targets chloramine in particular, using kdf-85 and catalytic carbon, both of which are optimized for removal of chloramine. CR-1 CHANGE THE CHLORAMINE CARTRIDGE ONCE A YEAR.
The second cartridge (either FR-1 or BC-1) goes in the middle and removes fluoride, and has a sediment filter. Select the activated alumina (FR-1) or the calcium-based carbon (BC-1). CHANGE THE FLUORIDE CARTRIDGE EVERY SIX MONTHS. If you wish, you can add an additional fluoride cartridge from this section of the store so you’ll have the filters you need for a full year. Both of the cartridges for fluoride removal, one using activated alumina and the other calcium-based carbon, do an excellent job. It’s just a personal choice; we do not recommend one over the other.
The third cartridge (last in line as the water flows) is the wide-spectrum, deep filtering replacement filter cartridge filter. It includes 2 sediment filters, copper-zinc kdf 55 and granulated carbon filtering media. It filters a wide range of contaminants, including chemical and organic-based, and heavy metals. We now offer a choice of wide-spectrum filters. The standard KR101N or the KR101A, which is the same filter with the addition of micro-fiber and cyst filtration. The issues of micro-fibers in the water have been more evident.
Change cartridges by unscrewing the canister (not the screws, the whole canister) by turning it counter-clockwise, which is the same as a pickle jar or light bulb or pretty much any other household item. Use the plastic wrench we sent you for free with your original filter purchase to gain more leverage if needed. Just put the new ones in in the same as the ones you are taking out. The cartridges say ‘up’ to indicate the top side IN AN UNDERCOUNTER CANISTER. IN A COUNTERTOP UNIT, put the ‘up’ end into the base.
The size of the filters is 3 1/16 across and 9 1/4 tall. If you got your canisters from us, this are the right replacements for a three-canister CHLORAMINE FLUORIDE PLUS unit whether it is a Countertop or Undercounter unit.
