I knew a guy at work a couple of decades ago who was extremely sensitive to organic vapors. Simply opening a dry erase marker in a nearby cube would send him to get medical attention. He wasn't faking it.
At one point he was trying out an air purifier from NASA that used UV light and titanium dioxide to destroy organic contaminants. The light creates electrons and holes in the TiO2, causing the contaminants to be oxidized. As I recall it didn't work well enough for his purposes (or perhaps created degradation products he also reacted to.) The notion of using TiO2 to make self-cleaning surfaces is also a fairly old one. One proposal had cars with TiO2 on their radiators, with the idea they'd destroy more smog than they'd create. If I recall correctly there are also TiO2 coated toilets in Japan.
I believe what you are referencing are hydroxyl generators. I looked into these vs ozone generators when I bought an old very stinky and smoke filled house. They cost a lot more than ozone but are thought to not be irritating like ozone. Plus ozone breaks rubber and silicone down.
