Frequently Asked Questions

Why do you show 674 sq ft here but the brand advertises over 3,000?

Both are Blueair's own numbers. 674 sq ft is the room size at 4.8 air changes per hour, which is the basis this site compares on. The larger figure describes the same unit running at roughly one air change per hour. We show the comparable figure and note the other one so the difference is visible.
