Frequently Asked Questions

How often should the intake bacteria filter be replaced?
Replacement frequency depends on the environment in which the concentrator is used and the manufacturer's maintenance schedule. In general, intake bacteria filters on oxygen concentrators should be inspected regularly and replaced when visibly dirty or discolored, or according to the concentrator's maintenance schedule — typically every 1 to 2 years for home use, or more frequently in dusty or high-use environments. Consult the Invacare Mobilaire or Platinum user manual for the specific recommended replacement interval for your model.

Is this filter compatible with all Invacare Mobilaire models?
Yes. This filter is designed for use with all Invacare Mobilaire models as well as the Invacare Platinum concentrator series. It is engineered as a direct equivalent to the OEM filter (Invacare #1131249) with the same port size and thread specifications for a proper fit. If you are unsure whether this filter is compatible with your specific concentrator model, check the model number on your unit and compare it against the compatibility list, or contact us before ordering.

How does this filter compare to the OEM Invacare filter?
This filter is designed to meet or exceed all OEM specifications, including purity standards and back pressure performance testing. The bacteria efficiency of 99.9720% and virus efficiency of 99.99% match or surpass the performance of the Invacare #1131249 OEM filter. The primary difference is price — this filter is priced up to 35% lower than the comparable OEM part, making it a cost-effective option for routine maintenance without compromising filtration performance.

How do I install the replacement filter?
Installation involves removing the existing intake filter from the concentrator's intake port and threading the replacement filter into place using the 22mm outlet and 3/8-18" internal threads. The process is straightforward for most users familiar with basic concentrator maintenance. If you are not comfortable performing the replacement yourself, contact a qualified home medical equipment technician or your DME provider for assistance. Always power off and unplug the concentrator before performing any maintenance.
