Then its an ozone generator with a creative description.
uv-c is worthless for odor control, as are ionizers. ozone works well but is dangerous, just like PCO which is nearly the same thing, just different
Study on Photocatalytic Oxidation (PCO) Raises Questions About Formaldehyde as a Byproduct in Indoor Air
Interesting fact, the higher velocity your air handler the higher the level of byproduct that is produced.
