Will these filters work on passive intakes, or do they need a fan in order for air to come through? I did a search and couldn't really find an answer. I was hoping to use this on a passive intake pulling air from outside into the basement, as well as 2 passive intakes on my tent.
I've read where people claim these filters are quite restrictive, leading me to think I'd need a fan. However, the websites selling them make claims as to "zero cfm loss" so that leads me to believe they just might work on passive intakes.
Sorry if this has been covered, I did do a search but couldn't find any definitive answers. They're not the cheapest so before I purchase 3 of them and some rejuvenation kits I'd like to make sure I'm not wasting my time/money.
