UV light fixtures "Upper room UVGI (Ultraviolet germicidal irradiation)" also seems to be a promising air-cleaning technique, with possibly fewer moving parts a

  UV light can sanitize (kill germs) but it won't clean (remove particles).

  UV doesn't really remove pollutants but chemically alters them which can also have unintended bad effects: https://pubs.acs.org/doi/10.1021/acs.est.1c02582 https://pubs.acs.org/doi/10.1021/acs.est.1c02582

    i think this is trying to raise awareness of those that produces ozone which is definitely a bad idea.. "careful selection of the UV wavelength and light intensity used in these devices may be able to mitigate unintended chemistry." Far UV-C 222nm done correctly would be great!
