Bedroom Air Purifiers
A bedroom air purifier should have a smoke CADR of at least two-thirds of the room's area, about 100 to 200 for most bedrooms, and a sleep setting quiet enough to run all night. Look for a display you can turn fully dark.
Bedroom checklist
- Noise on low or sleep: roughly 25 to 35 dB is quiet enough for most sleepers.
- Lights: a dimmable or switchable display and indicator lights.
- True HEPA: for dust, pollen and pet dander that collect in bedding areas.
- Placement: 3 to 6 feet from the bed, with clear space around the intake and outlet.
- Filter cost: a compact unit's filters often cost $20 to $60, and you will run it every night.
- Auto mode can ramp up loudly. Lock it to sleep mode overnight if noise bothers you.
For the lowest noise, see Quiet Air Purifiers. For a baby's room, compare Air Purifiers for Nurseries, with safety notes on cords and placement.
FAQs
Is it good to sleep with an air purifier on?
For most people, yes. Running a HEPA purifier overnight reduces airborne dust, pollen and dander in the room where you spend the most hours. Choose a model quiet enough on its sleep setting, switch off bright lights, and keep it a few feet from the bed so the airflow is not blowing directly on you.
What size air purifier do I need for a bedroom?
Multiply the bedroom's floor area by 0.67. A 12 x 12 ft bedroom (144 sq ft) needs a smoke CADR of about 97. Most compact HEPA purifiers meet that. Size up if the room has a vaulted ceiling or you want the purifier to reach that CADR on its quietest setting.
Where should an air purifier go in a bedroom?
Place it 3 to 6 feet from the bed on the floor or a low, stable surface, with a foot or more of open space around the intake and outlet. Avoid corners and spots behind curtains, which block airflow. Keep doors and windows closed when you want the purifier to work efficiently.
