Kingon Oxygen Sieve Bed for P2, P2-E, P2-E6, P2-E7 Portable Oxygen Concentrator

This is the Kingon P2 oxygen sieve replacement part only. The oxygen sieve is also known as an oxygen sieve bed, oxygen molecular column, or oxygen filter. It is a two stage filter system which removes nitrogen from atmospheric air using a depleted zeolite material.

No matter what portable oxygen concentrator you use, you must change your oxygen sieve every 12-18 months depending on usage. Even if the device isn't used frequently, the sieve needs to be replaced periodically as it absorbs moisture and becomes ineffective.

The R200 sieve bed is for Kingon P2 devices manufactured after October 2020 (Kingon P2 models manufactured before require the P200 sieve bed).
