I was also curious, as an owner of a box mattress and laminate flooring.

I used https://acsbadge.com/ to do a highly-accurate one time test of my home and was happy with the results. Piece of mind to determine if you have a potential issue or not. They also give guidance on how to interpret the numbers and what 'safe' means (results are in ppm concentration accurate to 0.002 ppm).
