We recommend changing the filter on your CPAP device every 3-6 months and taking it out and giving it a flick every fortnight or so. If you live in a dusty environment, we advise paying extra attention to this.
In the short term I don’t think you will notice too many benefits of this, but over time it will prevent dust build in the motor. Dust build up is one of the main reasons we need to send machines off after 3 years of functioning.
We think managing your filter is going to add at least an extra 12 months life to your machine, so we strongly advise staying on top of this. We send reminders to our patients every few months reminding them to change their air filters.
