If you're a regular breather of the GO+ Recreational Oxygen Purifier, you'll want to purchase replacement air filters every once in while, based on your individual usage. Two (2) air filters comes with the GO+ unit.
There are two air filters in the GO+ unit: 1) The External (Headset) Air Filter , and 2) the Internal Air Filter. Both air filters should be replaced when heavily discolored, or after around 100 hours of use, for optimal effectiveness.
Based on the average usage of 30 minutes per day, the External (Headset) Air Filter should last around 200 days - or more than half a year - if you use the unit every day. That's about 9.13 air filters per year.
MAINTENANCE: The GO+ Recreational Oxygen Purifier unit has two replacement pieces, air filters and zeolite filters, which help ensure the purity and percentage oxygen you're breathing. Swapping them out is easy. Check your owner's manual, or contact Oxygen Plus for more details or instructions on how to replace your air filters.
