Which filter to use

[Bluerhyno]

I've got a 6" vortex 440 cfm, just wondering which filter would be a good match, because I've read that if its not near the cfms the filter requires it wont do the job. Im close to start flowering and need to keep smell to a minimum.

phresh?
can-filter?
others?


Thank You.

Can filters work well for me.

Dont believe the hype. I run a 12 inch inline fan with a speed controller on it to a 8 inch Phresh filter.
I turn the speed controller to about half way on mine. If it is too fast then yes it will smell. I run a bigger fan to and turn it down so it is queit in my grow room
