Air quality in some countries is very bad. It becomes worse when the temperature drops during winters. There are a lot of air purifiers available in the market. Do they really work? If yes, which one would you suggest as per your experience?
EPA says: The research shows that filtration can be an effective supplement to source control and ventilation. Using a portable air cleaner and/or upgrading the air filter in your furnace or central heating, ventilation, and air-conditioning (HVAC) system can help to improve indoor air quality. It is important to use the following guide: Guide to Air Cleaners in the Home

I have tested many models of air purifiers/ air cleaners that are sold in my country.
And the demand for them is huge because in Poland we have very bad air quality. HEPA and electrostatic air purifiers are the best for PM removal. For odor removal, the best and cheapest are those with activated carbon filters. If you want to get rid of bioaerosols, HEPA filters and a UVC lamp are the best. I do not recommend purifiers with the function of photocatalysis and ionization.
