Make sure you keep your OxyGo portable concentrator working at peak performance by replacing the sieve beds (columns) on a regular basis. The easy-to-remove and install Columns are a quick and simple way to service your OxyGo at home, without the need for a repair shop. Replacement Columns are sold as a pair, and should be replaced at the same time. The column contains the sieve bed which converts room air into a high concentration of portable oxygen.
