Why does the airflow rate switch in the middle of operation on my Hitachi Air Cleaner?
If the airflow rate of your Hitachi Air Cleaner changes unexpectedly, it might be because the unit is set to “Auto” airflow rate or “Eco Saving Operation”. To resolve this, switch the airflow rate or select another mode. Also, ensure that the front panel and filters are correctly set; if not, set them correctly.
What to do if my Hitachi Air Cleaner does not come out air or it will not turn on?
If your Hitachi Air Cleaner isn't turning on or no air is coming out, check the following: Ensure the power plug is properly inserted into the outlet. Verify that the breaker is switched on.

Why my Hitachi Air Cleaner cannot be operated?
If your Hitachi Air Cleaner is not responding to touch, first, check if the child lock is activated and cancel it if so.

Why clean monitor display color does not change from red on my Hitachi EP-PF120J?
If the clean monitor display color on your Hitachi Air Cleaner does not change from red, it could be due to several reasons. The odor sensor might be detecting something nearby, such as heating appliances that generate combustion gases, alcohol, cosmetics, or sprays. In this case, the purifier may detect components of invisible gas that cannot be cleaned by the filter and still continue operating, so open a window for ventilation. Also, the dust sensor or the odor sensor opening might be blocked by dust or other objects, so clean the dust sensor and the odor sensor.
What to do if the airflow rate does not increase even though the air is contaminated on my Hitachi EP-PF120J Air Cleaner?
If your Hitachi Air Cleaner isn't cleaning the air effectively and the airflow rate isn't increasing, it could be due to a few reasons. First, check if the airflow rate is properly switched; if not, select Auto mode or another airflow rate. Also, the odor sensor opening or the dust sensor might be blocked or dirty, so clean them. Finally, if the air around the unit became clean while the power plug was in the outlet, try switching the airflow rate or unplugging the unit for 10 seconds before plugging it back in.
Why the clean monitor display color does not change from blue on my Hitachi Air Cleaner?
If the clean monitor display color on your Hitachi Air Cleaner remains blue, it may be because the unit is not able to detect odors and dust in its current location.

How to remove smell from my Hitachi EP-PF120J?
