Where can I buy a HEPA filter that replaces the filter that slides into my window air conditioner??
The AC seems to let pollen in (even though all the allergy sites say to use an air condtioner..so I’m pretty confused). Where can I buy a HEPA filter that will slide into my AC unit? It’s an LG LWHD8000R. Can anyone help?

get name of a/c unit and go to the place that handles that brand and they will have the filter or order one for you.
