I would suggest the Honeywell HPA series. I have a Honeywell HPA 300 and it is an absolute beast. It got me through living in an apartment with a mold infestation so bad there were 73,000 spores per cubic meter in the HVAC return air box. For context, the level of spores per cubic meter outside at my location measured at 11,000 spores per cubic meter. That place was a nightmare, but the Honeywell got me through until I could break the lease. It is also very very quiet on the lowest setting, almost silent. You probably don't need one as big as the HPA 300, but the 200 is a really nice size. My sister uses it for her asthma and dust allergy management.

Reply to My father has developed asthma in his mid 50’s and I think an air purifier in his bedroom would be really good for him. Do you have any recommendations? by C_A_N_G
