These are general placement principles. For sizing your unit to a space, see room coverage; the SonoHealth AirPro cleans 430 sq ft in about 10 minutes and up to 1,200 sq ft in 30 minutes.
Where should I put an air purifier?
Place it in the room where you spend the most time — usually the bedroom or main living area — with open space around it. Because the AirPro uses a 360-degree intake, it draws air from all sides, so a relatively central or near-seating position works well. A spot near common pollution sources (a litter box, an entryway, near a pet area) can also help.Where should I avoid placing it?
- Tight corners or behind furniture, which block airflow to and from the unit.
- Under shelves or in cabinets, which trap the clean-air output.
- Damp areas like directly next to a shower; humidity isn’t ideal for filters.
- Hidden, low-traffic spots far from where you actually breathe.
Does height matter?
Many pollutants and allergens circulate throughout a room, so floor level or a low table both work. Keep the intake and outlet unobstructed and leave a clear gap from walls. Avoid placing it where curtains or bedding can cover the airflow path.Bedroom and nursery placement
For sleep, position the AirPro a few feet from the bed so clean air circulates around you without the airflow blowing directly on your face. Its Night Mode runs at about 25 dB, quiet enough for a bedroom or nursery.One unit or several?
One purifier treats one room well; closed doors limit how far clean air travels. For a multi-room home, run the unit in your highest-priority room (often the bedroom) or consider additional units. Keeping interior doors open helps air circulate.Related: Room Coverage · How the AirPro Works · Best Air Purifier for Bedrooms · Air Purifiers for Pets
