FAQs

1) Is this the same as the internal bacteria/HEPA filter?

No. This is the external inlet filter you can service yourself. Internal filters are serviced per manufacturer protocols.

2) Can I wash and reuse it?

Yes—rinse and fully air-dry. Replace if the mesh is torn, misshapen, or discolored.

3) How often should I replace the inlet filter?

Typically every 3–6 months, or sooner in dusty environments/pet households.

4) Can I use the POC without the filter?

No. Operating without an inlet filter can allow debris into the device and may void warranty coverage.

5) Do I need a prescription to buy it?

No. It’s an accessory—no Rx required.
