I’m putting in a new hobby woodworking shop. The size is 34’ x 40’ X 10’. Looking to add an air filtration unit. What size and brand unit should I be looking at?

Get a good dust collector as a first step to keep the air in your shop clean.
Collecting at the source does more for the air quality than anything.

What size? For that size shop, you need a large one if you’re running ducting. That’s a lot of distance.
Also, most tools need to be modified to use larger hoses than what ports they come with.

You might want to read through this.

There’s an overload of information but you can get some ideas on the basics of dust collection. It took me my second time to get it right as I thought I could get it done with a harbor freight dust collection with a super dust deputy cyclone and still left a lot of dust in the air and over everything. My shop is 20’x40’x12’ so it’s not as large as yours. I ended up getting a 5hp dust collector running 6” ducting through the shop and 6” hoses to the tools or double 4” hoses.

Maybe try making your own. If you have an old high-capacity fan, make a box for it with slots for air filters. Mounted on a wall it should circulate and filter the air pretty well

You want a half micron filter bag. The dangrous stuff is in the 1-5 micron range.

A dust collector is not an air cleaner. In a shop that size you need one dc but may need multiple air cleaner.
