Read the limits alongside the numbers
Maximum CADR and minimum noise usually describe different operating settings. Filter price is not annual running cost. Room coverage needs a stated air-change rate. Our guides keep those distinctions visible.
The Home Briefing has not laboratory-tested these products and does not claim medical benefits. Air cleaning does not replace source control or ventilation; see EPA's consumer guide. Read how we compare products.
