They work for a short time and cost too much. Go electrostatic.
My woodshop has the typical tools and my projects include both non-exotic and exotic woods. The AP200 works sitting on a bookcase but the outer filter clogs quickly. Since these filters run about $24 in packs of two I stopped buying them and purchased an electrostatic filter that is washable for $44 delivered from Hechinger dot com.

Too expensive
The Delta A200 Shopmaster air filter is an excellent product, however Delta brand filters, at more than $12 each, are way too expensive! I ordered a box standard 12x24x1 furnace filters, 10 for around $32. When the filters arrived they were of equal or better quality then the Delta filters, HOWEVER, they are just slightly too large! Seems like Delta forces you to use their off-size filter, rather than an industry standard. I assume they see consumables as a high margin business.

I suggest you consider another other brand air filter system, like Jet, and determine if they can use standard sized filters. If yes, DO NOT buy the Delta air filter system. In the longrun, you will save a ton of money if you can use a standard filter.

Good Filter, but there is a better alternative
I've used these filters and they perform well, but I have since switched to the electrostatic filter and like it much better. It is much easier to clean and seems to do a better job filtering as well.

Great Product
This filter is excellent. It can be vaccumed or blown out several times without loosing it filtering ability. I do think that it is a tad expensive.
