Bonsai HEPAFLOW-12 & Bonsai HEPAFLOW-XL Replacement HEPA Filters. The rated filter life is 3,000 hours or 3-5 years of normal use. Dirty environments can reduce the lifespan.
Initially when I first got started in mycology I was having contamination issues. I tried still air boxes and had some success. This flow hood though is a game changer. Not once have I had contamination using it. So happy!
Couldn't be happier with my order. Shipping was free and was packaged amazing, showed up in perfect condition 5 days from ordering DURING Christmas/Holiday season. Great site solid products,
Hard to tell from the pictures they provide, but this filter has a quality aluminum frame, precisely 18x24 inches, and the depth is around 3 inches (don't remember the exact number). It would be nice if they would provide the static pressure, I would be surprised if it's as high as the typical filters in this category given the depth.
Incredible filter. Half the depth of most. This saves on space and electricity as you need a less powerful fan to achieve great laminar flow. I live in Canada and used this filter matched with a 460 cfm inline fan. Yes you can definitely get great laminar flow and a squirrel blower is not necessary. Complete build for under 700 bucks in Canada even after using 3/4 inch birch plywood.
works perfectly and was super easy to replace!
