7 Air Purifier Myths Debunked
Myth 1: You need one in every room
One properly sized air purifier can handle an open floor plan. Place it in the room where you spend the most time.
Myth 2: HEPA filters remove viruses
HEPA filters capture particles >=0.3 microns with 99.97% efficiency. Most viruses travel on larger droplets that HEPA can capture.
Myth 3: Bigger is always better
Match the CADR to your room size. An oversized purifier in a small room wastes energy and creates unnecessary noise.
Myth 4: Ionizers are better than HEPA
Ionizers produce trace ozone, which can irritate lungs. HEPA filters are more effective without harmful byproducts.
Myth 5: Air purifiers eliminate odors
Only purifiers with activated carbon filters remove odors. HEPA-only purifiers capture particles but not gases.
Myth 6: Run it once a week
Air purifiers work best when run continuously. Running 24/7 on auto mode uses minimal energy (30-100W).
Myth 7: Filter replacement is optional
Clogged filters reduce airflow by up to 50%. Replace HEPA filters every 6-12 months.
