Airfire AP202 Air Purifier User Manual

Not sure this is your model? On the AP202 the filter is reached by lifting the top cover straight up, and the filter comes out as one piece. If that matches your unit, this is the right replacement.

When to replace your filter

• Replace after about 1,000 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 power button for 5 seconds to reset — you'll hear a beep.

How to replace the filter

Safety first: unplug the USB power cable before you start.

1. Remove the top cover by lifting it straight up.
2. Lift out the old filter.
3. Remove the plastic wrap from the new filter. Running the purifier with the wrap still on blocks airflow and can cause it to overheat.
4. Place the new filter into the purifier.
5. Refit the top cover firmly. Plug back in, then hold the power button 5 seconds to reset the indicator.

Keep your filter working between changes

• Clean the outer pre-filter every 2–4 weeks with a soft brush or vacuum to clear hair, dust, and large particles.
• 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 power button for 5 seconds to reset.
• Reduced airflow or odor removal? Clean the pre-filter, or replace the filter if it's due.
• Not feeling the effect? Check the filter is seated correctly and the top cover is closed, and that the inlets/outlet aren't blocked (keep 20cm clear).
