I'd love you or the company to explain how only hydroxyl radicals and no ozone will be produced in a very dry air, considering it is physically impossible. Even the companies own patent application information explained that the amount of hydroxyl to ozone production would vary according to humidity. Don't let reality and physics get in the way of the story..
Here is another simple reality for holders... If it was possible to get just hydroxyl free radicals to totally purify the air in a small confined space of the air purifier, before releasing the air back into a room, it would have been for sale by a major company decades ago, because both ozone and hydroxyl free radical generators have been around for decades. The problems with this type of tech are multiple, the humidity factor of the air going in being just one of them.
If there was no ozone produced by a range of humidities, then show this by having an independent lab do the testing with a range of humidities. It would be very simple to do, but somehow they decided not to do so. Just word from the company that it's not an issue is irrelevant. The company selling thalidomide to women also said it was safe. You need independent testing to show what is or isn't an issue.
Also they didn't test a range of common household or business odors that would be expected to go through the air purifier. Free radicals change the chemical structure of whatever they touch, so some seemingly innocuous odors can be changed into something dangerous by a brief touching of free radicals.

Go and have a read of this site, not just because of the discussion about ozone and 'ionizers', but the shear number of products already in the market.. https://moderncastle.com/air-ionizer-dangers/
There are basically hundreds of products for air purification that involve some type of 'ionizing' the air that goes through the unit, with all sorts of claims by manufacturers.
It basically comes down to low energy units might produce 'safe' levels of ozone, but are ineffective at purifying the air. High energy units produce lots of ozone and are unsafe to be in occupied spaces but they do clean the air. Many of the products in the comments section claim to be hydroxyl generators with no ozone, but the same applies, low energy units equals no real cleaning effect on air, high energy units produce dangerous levels of ozone as well as 'cleaning' air.
The bottom line is that there are already hundreds of products in this market, so even if they get the FRG unit into an air purifier, there is not much profit, if any, to be made in a highly saturated market.
Also, don't think that just hydroxyl radicals produced means something is 'safe' .....
"This finding leads to the possibility of higher chemical reactivity in the indoor environment, which has previously been neglected. Reactions of alkanes and aldehydes, which are ubiquitous indoors, and of aromatics with OH radicals thus may lead to the increased formation of potentially harmful secondary organic aerosols inside."
