Is there any need to change the filter inside the LiveO2, LiveO2-AC or in the air separators?

The AirSep 5L air sep­a­ra­tors are very tiny pored air fil­tra­tion devices already, so they will fil­ter envi­ron­men­tal con­t­a­m­i­nants from both the oxy­gen and alti­tude feeds. There is no need for any main­te­nance with the AirSep 5L air sep­a­ra­tors nor are there any fil­ters to be changed.

For the mod­i­fied 10L AirSep, there is an exter­nal fil­ter that requires main­te­nance. There is a foam like fil­ter on the back of the 10L AirSep units. Remove this fil­ter and wash in warm water with mild soap. Allow fil­ter to dry com­plete­ly in the open air. Replace in AirSep unit before use. AirSep rec­om­mends clean­ing the fil­ter month­ly. Depending on your house­hold liv­ing con­di­tions (pets, smok­ers, dust, etc.) you may choose to clean your fil­ter more often.

As far as the LiveO2 and LiveO2 AC Reservoirs, they are built with an inter­nal car­bon sock fil­ter inside which serves two roles:

  1. It sep­a­rates and holds the reser­voir away from the intake tube to pre­vent the reser­voir from col­laps­ing around the tube to pre­vent cav­i­ta­tion until the reser­voir is emp­ty.
  2. It serves as a fil­ter to absorb any con­t­a­m­i­nants that may occur post-man­u­fac­ture.

The inter­nal fil­ter does not need to be changed since it exists in a closed envi­ron­ment between the air sep­a­ra­tor, and there is no oppor­tu­ni­ty for con­t­a­m­i­na­tion post man­u­fac­ture.
