Ah yes the yearly several months of "can't see the sun from wildfire smoke" we've had on the West side for years hits the east coast.
My biggest suggestion is stay inside as much as possible, avoid opening doors/windows unless necessary (every instance lets in another whiff of smoke). If you have anyway to create "air locks" where you have multiple doors before the main house use that (hang a sheet over the entry way even helps.. I usually use the garage entrance which provides an extra door layer). Masks / decent respirators DO help if you have to go outside, as a woodworker we should mostly have some of these anyway. Antihistamine Visine Eye Drops and Nasonex or similar products can help with the irritation (but I'd stay inside rather than going to the store on a 50/50 choice.. but if you're at the store already..)
For clearing air inside the house variants of these DIY air filters are basically yearly builds on the west coast and they do 100% help:

I make the square box kind with 2 or 3 filters with cardboard bottom/sides and filter front/top have the fan pushing sideways towards them and put it in the hallway so it sort of circulates through the house more.
Also replace your furnace filter and turn the fan for that on to pull some of the smoke out of the air.
Make sure windows & doors are closed as well. If you see leakage around them don't be afraid to temporarily tape it all shut.
A couple years ago we bought a
