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.
REPLACE THE CANISTER O-RINGS EVERY 4 YEARS FOR UNDER SINK, EVERY 6 YEARS FOR COUNTERTOP. (Click the links)
THIS IS THE ORDER YOUR FILTERS GO IN:
The first cartridge (CR-1) as the water flows targets chloramine, using kdf-85 and catalytic carbon, both of which are optimized for removal of chloramine. It is however, an excellent wide-spectrum filter as well, filtering hundreds of contaminants. 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). Both options for fluoride removal, activated alumina and calcium-based carbon, do an excellent job. It’s just a personal choice; we do not recommend one over the other. Vegetarians will prefer Activated Alumina.
CHANGE THE FLUORIDE CARTRIDGE EVERY SIX MONTHS. We suggest that you add the additional fluoride cartridge to your order to save on shipping, and so you’ll have the filters you need for a full year.
The third cartridge (last in line as the water flows) is the wide-spectrum,
deep filtering replacement filter cartridge filter. It can be either a KR101N (wide-spectrum), or a KR101A (wide-spectrum with microfiber + cyst filtration.) Click this link to our blog on microfibers.
Both have sediment filters, copper-zinc kdf-55, and granulated carbon filtering media. They filter hundreds of contaminants, including chemical- and organic-based, and heavy metals.
From The Story of Stuff:“Microfibers are showing up in even more unexpected places. Recently, we commissioned a lab to look for microfibers in bottled water – and we could hardly believe what we found.1 Out of 20 bottled water brands we tested, all but one contained plastic microfibers. Previous studies have also found plastic microfibers in tap water.2 Scientists even warn that we’re likely breathing in these plastic microparticles!3″
