Using an air purifier properly

WIRED Gadget Lab Logo
By Lisa Wood Shapiro | 07.30.24I’m not saying I would do this, but if I visit your home, I might look around to see if you have an air purifier.

If you have one, I might estimate the cubic footage of your room and then, if I’m left alone, I might open the purifier to look at the filter.

I know I’m being a bad guest, but I am in the service of a greater good. Depending on what I find, I will fight the urge to tell you that your air purifier is too small to effectively clean the room, or that the purifier shouldn’t be placed against a sofa or a wall, or that the filters need to be changed, or worse—the plastic encasing the filter was never removed when the purifier was first purchased.

This urge to give unsolicited indoor air advice goes deep. I knew no better until I was on the air quality beat. I didn’t think about my indoor air, nor did I understand how making a few changes and using an appliance or two could have a lasting impact on my health, the quality of my sleep, and my mental acuity.

And I want the same for you. Be sure to check out our related guides, like the Best Air PurifiersBest Indoor Air Quality Monitors, and Best Robot Vacuums.If you buy something using links in our stories, we may earn a commission. This helps support our journalism.
