This is a rather different thing. The carbon filter removes VOCs and maybe some ozone and NOx — it’s for gasses. A normal air purifier is for small particles.

You can certainly do both, and you can surely add a MERV 13 or better filter to the “industrial” solution, but as you describe them, they address different problems.
