Frequently Asked Questions (FAQs)

Should a room air purifier run all the time?

Air pollution is always present, so it’s best to keep your air purifier on all day. However, there are no drawbacks to leaving your unit running constantly, and changing the filters according to the manufacturer’s schedule can reduce pollutants in your home.

How long can you run a room air purifier?

It’s best to leave your air purifier on all day if possible. Doing so will rid your indoor air of dirt, allergens, smoke, and odors. Additionally, the longer you can keep it running, the cleaner your air will be. There are no real disadvantages to leaving your device on 24/7.

Can I use an air purifier for a room with the window open?

Although you may think keeping the windows open would be better for ventilation, an air purifier can make a significant difference. In fact, with the windows open, we found that particulate levels were reduced by 60% in only 20 minutes.

How much electricity do air purifiers use?

Room air purifiers are portable, electric appliances that remove particles from indoor air. A standard room air purifier uses approximately 450 kWh annually in electricity when operated continuously.

Does the room air purifier remove dust?

In short, yes, most air purifiers will remove large dust particles from circulation. A common way this is achieved is through mechanical filtration, where pollutants are captured on filters which either cause the particle to stick or be trapped within the filter fibers.


Home air purifiers can help improve indoor air quality and reduce exposure to harmful particles and pollutants. If you’re looking for an air purifier for your home, there are a few things to keep in mind. It’s important to remember that no single air purifier can eliminate all indoor pollutants.
