This is a bonus air-cleaning feature that uses negatively charged ions to clean the air in your environment. This gives you ionized air, which is known to be a mood enhancer and odor neutralizer.

3. Touch Panel Display

This can be found on top of the Airdoctor 4-in-1 Air Purifier and is used to control the purifier. With this, you can efficiently control the settings and modes of the Airdoctor purifier.
