Different purifier technologies target different indoor pollutants.
Homes in high‑pollen or urban areas often use HEPA and carbon filtration to reduce allergens and odors for cleaner indoor air.
Replace or clean air purifier filters on schedule to maintain airflow and filtration performance.
“Replace or clean air purifier filters on schedule to maintain airflow and filtration performance.”
HEPA filters were developed during the Manhattan Project to capture airborne radioactive particles.
Where should I place an air purifier?
Place it in the room where you spend the most time, with a few feet of clearance for airflow and no obstructions near the intake.
Are ionizers safe?
Some ionizers can produce ozone. If you choose one, make sure it is certified low‑ozone or consider HEPA/carbon systems instead.
How often should filters be replaced?
Most filters need replacement every 3 to 6 months, but check the manufacturer’s recommendations and your indoor conditions.
