About this product
This is the cartridge set for the 3M R8-39G reverse-osmosis purifier, sold through the brand's own storefront. The set covers the filtration stages, so confirm your machine is exactly the R8-39G and not a sibling model with a different cartridge layout before ordering. Cartridge life depends on feed-water quality and household usage, and a drop in flow rate or a change in taste is the usual signal to replace. Suits households already running the R8-39G; if you are unsure which generation your purifier is, take a photo of the label and confirm with the seller.
