How do you test/check purity of a oxygen concentrator?

Many modern units now have their own oxygen purity indicator and will alarm when your unit's purity is becoming too low. If you are not sure if your unit has its own oxygen purity indicator please refer to your owners manual. If you do not have your owners manual it may be found here: http://www.oxygenconcentratorstore.com/portable-oxygen-concentrator-manuals/
