Ugh I hate unknowledgeable people talking about construction.
Plywood also contains formaldehyde. Urea-formaldehyde glue is used in most all manufactured wood products because its cheap and effective.
Most of the cancer concern about it came from UFFI urea-formaldehyde foam insulation, because it got mixed formaldehyde rich so it wasn't just goop in the wall. Urea dissolves it, which is why dog and cat piss will delaminate a sub-floor.
Off-gassing is negligible unless your house is getting drenched in piss. You're also supposed to have a proper air barrier on your interior, so off gassing shouldn't be entering your house. If you're concerned you should be more concerned about the LDF and MDF made in China furniture people stuff their houses full of.
I think formaldehyde has been a constituent in modern rug manufacture, giving rise to the "new rug smell." It will outgas and be gone, but it can be chemically eaten up by ozone from an electrical ozone generator (turns it into water and carbon dioxide). Just don't go nuts on the ozone level. Ozone also eats up any organic smell.
The proper way to use them is run the ozone in a closed area, then when itβs done marinating then open up the windows and air everything out. I used one and it made an old house smell nice and fresh
I had heard that the offending chemicals will continue to be released after a dose of ozone but I could be wrong. On the other hand remain inert without the exposure.
Nonsense. It is an oxidant and combines with hydrocarbons as I mentioned. It is wise not to crank up the concentration, which is why ozone generators have an adjustable output. Ozone is the fresh smell that appears after a thunderstorm. I have had them in my household for years, with no harm whatsoever. Kitchen (and other odors) are effectively eliminated by its chemical digestion action.
What, pray tell, was the "stuff that was previously inert"? I am curious. And who says so?
Reactions between ozone and material surfaces may also result in oxidized by-products yields, including C1-C13 carbonyls, dicarbonyls and hydroxycarbonyls [[36], [37], [38],[41], [42], [43], [44], [45], [46], [47], [48], [49], [50], [51], [52], [53], [54]], which can adversely affect occupants' health and perceived air quality [18,29,45,[55], [56], [57], [58], [59], [60], [61], [62], [63]]. These by-products are usually produced from reactions between ozone and the unsaturated organic compounds that constituting or adsorbed on material surfaces [29], while inorganic materials usually exhibit negligible by-products yields [37,38,45,64]. Some of these by-products with low vapor pressures can nucleate to new particles or condense on existing particles to form secondary organic aerosols.

Ozone generators will end up putting lots of bad stuff into the air; like stuff that was previously inert. They are not recommended.

I couldn't do all the research intended but this is the gist of it. Just trying to give people info to consider. No need to get bristly.
