This is the replacement water filter cartridge set for our Oyster-TBC.

Improve the taste and odour of your water and remove chlorine and sediments. Remove bacteria including Campylobacter, E.Coli, Cryptosporidium and other cysts, for e.g. Giardia. In addition, Chloramines, Trihalomethanes and PAHs, pharmaceutical residues, endocrine disruptors, hormones are also removed.

Both cartridges remove chemicals.

Why do I need to change the o-ring?

You can tell if the seals start leaking, which is obvious, I know.

Even if there are no leaks you may find that the profile of the O ring becomes flattened because of prolonged time under compression. The cross section should be round and if it's not it may not seal easily.

However, I recommend that you replace the O rings every two or three years as a precautionary measure.

One of the main reasons for changing O rings periodically is that as they age and compress, the housing bowl needs to be tightened excessively. That leads to difficulty loosening the bowl from the cap next time the cartridge needs to be replaced.
