Airfire AP201 Air Purifier User Manual
✓ Confirmed fit — Airfire AP201 air purifier
- Filter type: True HEPA H13
- Design: one-piece filter + base (a single integrated unit — not a loose cylinder)
- Replace: about every 2,000 hours of use
Not sure this is your model? The AP201 uses a one-piece filter that twist-locks into the base. If your unit unlocks with a twist handle underneath and the filter and base come out as one piece, this is the right replacement.
When to replace your filter
- Replace after about 2,000 hours of use.
- When it's time, all indicator lights on the control panel flash.
- Replace sooner if you notice weaker airflow, less odor removal, or you run it in heavy smoke or pollution.
- After fitting a new filter, press and hold the HEPA / filter-reset button for 5 seconds to reset the indicator.
How to replace the filter
Safety first: unplug the power adapter before you start.
- Rotate the twist handle on the base counterclockwise to unlock.
- Lift out the old filter.
- Remove the plastic wrap from the new filter. Running the purifier with the wrap still on blocks airflow and can cause it to overheat.
- Place the new filter in and refit the base cover.
- Turn the filter buckle clockwise until it clicks into place. Plug back in, then reset the indicator.
Keep your filter working between changes
- Brush or vacuum the white side of the filter regularly to clear hair and dust.
- Never wash the filter with water — it damages the HEPA material.
- Do not add essential oils to the filter. Oils can damage it and cause odor. (Use the aroma pad in the aroma box only.)

Troubleshooting
- Lights still flashing after changing the filter? Press and hold the filter-reset button for 5 seconds.
- Reduced airflow or odor removal? Clean the filter, or replace it if it's due.
- Not feeling the effect? Check the filter is seated and locked correctly, and that the inlets/outlet aren't blocked (keep 20cm clear).
