I work in the production of HVAC for heavy roofing blocks in commercial buildings and hospitals. MERV 13 is a secret. To be honest, I haven't been sick in over 3 years. I'm not saying there's a direct connection, but there is a possibility. I think it's cheap insurance. In addition, we hold Christmas events and family celebrations, and family members who are allergic to cats do not even have a problem. Of course we also use a HEPA vacuum cleaner. However, I highly recommend the filter.
