BUSH AIR PURIFIER

• Check if it's plugged in securely.

• Ensure the power outlet works (test with another device).

• Make sure the power switch is on.

• Some models won’t start if the filter cover or housing isn’t properly closed.

• Check for a tripped circuit breaker or blown fuse.

If your air purifier is making a loud noise, please check the following:

• The filter may be clogged and needs cleaning or replacing.

• The fan could be obstructed or off-balance.

• The unit may not be sitting on a flat, stable surface.

• Inspect for loose parts or panels.

If your air purifier is not improving the air quality, please check the following:

• The filters may be old or incorrect for your model.

• The room might be too large for the unit’s rated capacity.

• Windows or doors may be open, letting in pollutants.

• The unit might be in the wrong spot—try placing it centrally or near sources of pollution.
