Are these the same respirator?

Yes. Both are the 3M 6000 Series full facepiece with a bayonet connection, 4-point harness and no filters included. B is the large size; A does not state a size.

Which is better for painting and sanding?

Either facepiece works; the difference is the cartridge. Pair it with a P100 particulate filter for sanding or a gas/vapor cartridge for solvent paint, and confirm the size fits before you buy.

Is the 3M 6000 worth the extra $50.87?

No, unless A turns out to be your exact size. The facepieces are the same model, so the higher price buys no extra protection.

Does either come with filters?

No. Both listings ship the facepiece only, so budget for 3M cartridges or filters separately.

Can I use either with a PAPR or supplied air?

Yes. Both are listed as compatible with PAPR systems and 3M supplied air setups, using the same bayonet fittings.

How long does the facepiece last?

The silicone facepiece is reusable and lasts through many cleanings. Replace it when the seal degrades or the lens is scratched enough to impair vision; filters have their own change schedules.
