has anyone used one of these to filter pollen? I'm building a isolation/pollination chamber. My exhaust fan for the chamber is a 4" 188 cfm inline fan. I need to filter both intake and exhaust and curious of the quality and weather this can be used for both. The chamber is gonna be sealed up fully and drip irrigated where its in my flower room. I'm also considering installing several pc fans individually controlled or set up to give a light swirl affect for maximum pollination in open air. My chamber is L77" x w36" x H42" The top and front is mostly glass. Its intake draws air from a co2 enriched room just off the floor and dumps on the other side up high. The male will be in the intake side and the females will be down wind. 2 sets of sand blasting gloves will be installed in the front with needed supplies inside and an empty sealed ammo box to put any dead leaves so there sealed up and don't cause any issues. Any add on ideas and thoughts on the can fan filter would be greatly appreciated. Maybe some do's and do not do's from anyone with experience would be great to.
