CleanBreath Lab exists because air purifier marketing is a mess of vague claims and meaningless numbers. We try to fix that with consistent, repeatable testing.
We judge purifiers on real metrics: clean air delivery rate, true HEPA filtration, noise at each fan speed, and the long-term cost of replacement filters. We are skeptical of ozone-producing ionizers and inflated room ratings.
We earn affiliate commissions when you buy through our links, and that funds the testing. It never changes where a product lands in our rankings.
