HEPA Air Filter for Air Travel

[Agoldsc1]

I'm planning to fly commercially from NYC to MIA with my 5 month old son. Would it help with Covid protection if I bring a portable HEPA air filter with me to the airport and on the plane? I know that the airport is obviously huge, but if I attach a filter to the top of his stroller, would it at least clean the air immediately around him? I'm considering something like this product: https://www.amazon.com/Westinghouse-Portable-Purifier-Filter-Technology/dp/B087V6CBT4/ref=sr_1_3?crid=2W88RQJWUZ86E&dchild=1&keywords=hepa+air+purifiers+portable&qid=1610846240&sprefix=hepa+air+purifiers+p%2Caps%2C177&sr=8-3

Thanks!
