Air purifiers can range in price and efficiency so we advise to talk to one of our comfort consultants. With that being said a great option is the Lennox Pureair. The PureAir is extremely efficient in removing odours and chemical vapors produced by pets, cleaning products, etc. What makes the Pureair so superior is the fact that it is a whole home system that eliminates 90% of germs and bacteria down to .01-micron, removing 90% of viruses like flu and MRSA. Lennox claims this filter removes particles as small as Covid 19 and SARS.
