Review on Aprilaire 216 Allergy Asthma Purifiers by Alex Smith

COVID-19 is upon us and many of us are now spending most of our time at home rather than outside. This antivirus filter "216" noticeably changes the air quality in our home. Children have fewer breathing problems, and while the system is running, the smoke they create while cooking their own food appears to be less trapped than with previous, less powerful filters. I haven't noticed any reduction in heating/cooling efficiency, significant billing changes, increased repair costs, etc. Does it filter viruses and thus offer protection if an infected person enters the house? I can't know and wouldn't count on it anyway.
