Companies like Air Oasis have products that promise to purify the air by:
The Air Oasis brands of Air Purifiers that we carry use a unique nano Nickle catalytic hydration process to create powerful purifying hydroxyls, or hydroxyl ions (OH), which are, in turn, used to create additional friendly oxidizers to purify the air.
A kickstarter project claims:
An international study being conducted over the Indian ocean which, in part, measured hydroxyl ion levels, led a team of atmospheric experts to conclude that without hydroxyl ions, air pollution can remain at toxic and harmful levels for much longer, increasing the likelihood of negative effect on humans.
Provided the technology can actually release the hydroxyl, does this make the air healthy for humans?
