The answer to this questions differs depending on an air purifier you are using:
- If your air purifier is a tower-like, with 360° air intake, then there no difference what it’s facing, as the air is pulled in from all sides and exhausted at the top. Examples are Levoit air purifiers and many others.
- If your air purifier sucks in air from just one side (e.g. Coway Airmega), either from a front or back side, then this side has to face an area that you want to be cleaned.
If you still have questions, feel free to ask them in the comment section.
