A still-air box keeps air still so less settles on your work. A flow hood blows HEPA-filtered air across your work surface, so particles are carried away and you can work with an open front and both hands free.

Comparable 2×2 flow hoods we checked in September 2026 cost $699 to $899.95. Steriflo is $499 with free US shipping. A single failed batch costs roughly $100–140 in grain, substrate and culture, so about four failed batches cost as much as the hood.
