Tondiamo 22 Pcs PE Valve Filter Set Replacement Valves for Coffee Canisters with 2 Rubber Rings, Degassing One Way Breather for Bean Container, Bag, Food Bags

The rubber rings and the valves are a perfect fit for my Friis coffee canister. I had made a purchase from a different company but they didn't fit at all. I'm sending them back.

As a coffee drinker, I want my coffee grounds to stay fresh before brewing. These filters are easy to replace and fit perfectly.

Easy to use. Great price.

I bought this to get the gasket (I.e. o-ring) for a friis canister. This fits nearly the same. Whether the gaskets or valves are as long lasting or as good at keeping coffee fresh will be determined another time but at least it fits (another brand on Amazon did not and was meant for a water hose)

DO NOT BUY: these valves are defective and leaky.

Does not seem to have any filtering material as the original one .. I cut open a new one and just plastic with a plastic looking disc .. no filter material as in original one so not sure how this will work

If this fits your coffee canister, congrats, you made a decent purchase. HOWEVER, if your filters never looked like this and had the filter fitted within the gasket, take this as a warning and keep looking for another set of CO2 filters. These crappy things will not fit.

I purchased a stainless steel coffee canister to keep my coffee grounds fresh. By changing out the C02 cartridge every 2 months my coffee is always fresh tasting and fresh smelling. I buy ground coffee in a bag and the old way after a short time when I opened the bag the coffee lost its fresh scent and taste, but not when you use the C02 cartridges, I have fresh coffee all the time now.
