Yes, and yes. Do you need to? We think so. Particle pollution in your home is often from ongoing, regular sources (dust and pets, mold, pollen, cooking, wood-burning fireplaces) or it could be episodic (a nearby wildfire, for example). Or both. Poor environmental air quality affects you inside your home, too.
Particle pollution is also dynamic within a room over the course of daily life. Doors open and close. People move from room to room. So do pets. And so do airborne particles. Rooms aren’t airtight. Windows leak. Heating systems exchange indoor and outdoor air.
Because of multiple types and sources of invisible particle pollution, we recommend leaving your Brio air purifier on, all day and all night. Set the fan to medium for everyday conditions and turn it to high when you need deep cleaning. The fan speed setting will also depend on the room size and your specific needs.
As there is less air movement at night, air purifiers can often be turned to a lower setting at bedtime. This really depends on the level of particle pollution and the effectiveness of your air purifier at a low fan speed. If you wake up in the morning and your air quality has gone down, you may want to turn the fan to a higher setting.
To gauge your air quality, we recommend using an independent air quality monitor for the most accurate information.
