Agree with Hobby_Maan22, If odors occur, there are no filter affordable to a normal person which will remove them. Filters to eradicate odor are extremely expensive, and require a large space. Charcoal filters on the devices we have in our homes are useless, it would take a ton of activated charcoal to provide long term odor control. With any shop/garage attached to a living space I believe you would need to have plastic sheeting envelope (with sealing) the entire wall area connected to the shop/garage area.
