We do! A small one in each bedroom/office, and a huge one for the open living area. They’re pricey but with seasonal air pollution, wildfires, and allergens, they’re a must-have for us and baby. Plus with COVID, we’ve run them the few times that we needed to have work done/strangers inside the house. We also have an air quality monitor for inside the house to confirm that the filters are doing their job, and to know when to run them efficiently.

We have this large one that cleans out a huge living area in about 20 minutes: https://www.amazon.com/AIRMEGA-AP-2015F-Smart-Purifier-Graphite/dp/B0722YZ1R1/ref=asc_df_B0722YZ1R1/

And these for smaller rooms. My dentist also uses this model so I assume they’re good. https://www.amazon.com/LEVOIT-Purifier-Home-Allergies-Pets/dp/B07VVK39F7/ref=mp_s_a_1_3

Ah, yes that definitely happens with the paper. The fan is connected to an enclosure/hood which is sealable.

I bought a TVOC/Formaldehyde measuring device on Amazon also. Are these things reliable?

Taking measurements at different stages during the printing process as well as before and after have not shown increasingly unsafe levels of VOC or anything else that it measures for. There is no noticeable smell also, but of course, I'm wearing a 3M mask with VOC filter.
