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.
The proper way to use them is run the ozone in a closed area, then when it’s 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.
Yeah it’s a bit mixed. Some people who know about ivermectin and others are in favor of ozone but it’s still fringe. I like the idea that it can kill mold structures below the surface. It should be viewed as any other strong chemical make sure to ventilation
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.
I agree I would be skeptical of the official science articles. I got a building biology certification and I remember it mentioned that ozone generators had the side effect of unleashing other undesirables.
Also never want to breathe it in. Sharper image actually went broke because of health lawsuits from their air purifier. Fun fact.
It took me a year of searching every day to find a home. So many of these homes were covered in this crappy partical board. I saw how it reacts to water (rain) it blows up and expands like a sponge. It's a shitty building material. I found two people father and son building homes. I went up and looked at the construction. All wood NO partical board. They also used only copper for plumbing. It was the first time I found a solid builder. The father was proud of the quality he put into the homes. I bought it on the spot. We shook hands and completed the sale in the following week. But yes, do the legwork look at the construction and see what you are buying. The partical board is crap. I knew it was cheep and I instinctually avoided it. If a house had it I would walk away.
Better not think about what you wear on your back, wash with, drink out of, sleep on etc. Better off just believing God to protect you than fearing everything around you.
Several decades ago I lived in a brick house in the UK. We had the cavity walls filled with urea formaldehyde foam. It outgassed so strongly for several days that we couldnt use the kitchen. (I guess there were holes where pipes went through the wall.) We had to keep windows open until the smell and stinging eyes sensation stopped.
But we haven't developed cancer.
And now we live in a reinforced concrete house in Greece with external polystyrene foam insulation.
EDIT. Actually the house has a reinforced concrete skeleton with hollow brick infill and a cavity between the infill walls.
Meh. I built my house with Roy O'Martin sheathing and it has one side covered with aluminum foil for radiant heat protection. The foil side is oriented to face to the inside of my house. I tried to tape every visible seam for better air tightness within the house. So that crap has something it needs to penetrate before it gets to me. Also, doesn't the sheetrock and paint provide additional layers of protection? I'm not too worried about it.
Sounds like Mr. Rogers. :) You are correct, I've e got way too much to worry about. Plus the abatement program would be a nonstarter for me. All the siding and 2" of polyiso insulation to pull off just to get to the sheathing. Then having to pull my metal roof off??? Naw, that amount of money, time, labor,and frustration is not going to enter my equation.
This type of fear mongering is ridiculous. OSB simply containing formaldehyde does not mean you live in a cancer producing box designed to kill you. This is like saying producing anything with alcohol makes it a ticking time bomb that can go off at any moment or ignite without warning and catch you on fire.

Agree
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.

After living in California, Prop 65 told me everything and anything can give you cancer.
Has California banned OSB yet?

Wood is incredibly expensive here.
