I got a formaldehyde detector. A "Dumb" one (https://www.amazon.com/gp/product/B00SIYDUUM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 https://www.amazon.com/gp/product/B00SIYDUUM/ref=ppx_yo_dt_b...) and also a Foobot - which is an IoT detector. They generically measure "VOC". The only reason why I knew of this is because my wife is from China and it's more regulated (kinda funny, isn't it?) and people know to let their house breathe before moving in. Otherwise I'd be celebrating our "new house smell"...which would prob linger for months and months in an average American home since families don't like to open windows.
