air cleaner

so im gonna do a closet grow with 3-4 plants. whats a simple cheap effective air cleaner i can use to keep the smell down. would an air purifier work?

I was quite surprised but a air purifier are quite good i use one when cropping and drying makes me feel better does kill the smell. However in saying that i would not run without a carbon filter look to get one at some point some strains give off some serious strong smell.

You only get one chance to get caught play safe
