For particulates (smoke, dust, allergens, etc.) you can get a good HEPA filter. For odours and VOCs, filters with active carbon can work extremely well but you need one with a big mass of carbon. A carbon filter is easier to jerry-rig to a fan, air duct or existing HEPA air purifier because they often have a very low airflow impedance. |
