Still Air Box (Large Still Air Box Version 2, Royal Blue)

I use this for plant tissue culture at home, it's a little nicer and easier to see through than a still air box made form a tote. Overall, I think it serves it's purpose well enough and is easy to setup. It has some small issues which are probably difficult to remedy with the design... it's light so it moves really easily unless you have it well weighted and you can feel air move in and out when you move your arms simply because it moves the plastic sheeting that covers the whole thing. I guess any SAB would have air go in and out as you move simply because of displacement; however, this one probably does it a little more. The 3-layered arm holes are a nice touch, I spray some alcohol in between them when I put my arms in and out, which I hope helps prevent any microbial contamination while I work. I'm pretty new to all of this, so I don't have a lot of experience to go on. I think I'll eventually move to a cheap flow hood from etsy or create my own., but this will do for now.

I purchased the Bella Bora Still Air Box expecting a reliable solution for sterile work, but in practice it does not function as advertised. The arm holes are extremely tight, which creates a piston-like effect — I can feel air rushing in and out and even see the sides of the box “breathe” as I move my arms. The box is very lightweight and flimsy, and it shifts around during use, which further stirs up air and defeats the purpose of maintaining a still, contamination-free environment. The plastic panels are wrinkled and distort visibility, making it difficult to work with small tools or observe details. The thin, flexible structure bends at the top when the outer zipper is fully closed. Additionally, the sealed arm holes make it impossible to safely flame-sterilize or pass heated instruments inside, which is essential for aseptic technique. Overall, despite the company’s claims that the “piston effect” does not occur, my real-world experience proves that air is moving inside the box. The combination of tight arm holes, light and flexible construction, and awkward tool access makes this product unsuitable for true sterile work. I cannot recommend it.

Great value. The air box assembles easily and seems to do a good job. That said the horizontal pieces seem to be a tad long, stretching the zipper and causing them to arch in the middle. I will probably replace the inner structure. The bag itself is great and at a fair price.

Love this SAB! Made it into a fully automated mini Martha. Use it for everything from agar and transfers to cultivation ad harvesting. Really cuts down on contamination. Quick to set up, take down and clean. Highly recommend!

Good concept, improvements made by the creator seem to have solved some problems noted by other customers. However, the design is still flawed, as the ovoid shape the elastic in the arm holes creates does not allow for a seal, leaving a relatively large triangular gap above and below arms, regardless the positioning on my arms. This creates an EXTREMELY noticeable draft during use, to the degree that it can even be heard. This is directly contradictory to the assertion against the “piston effect” (aka bellows effect) made by Bella Bora on their website. Will post video of vapor being pulled in through the seals when I get a chance to record it. I very much wanted to like this product, and believe it has the potential to be great. But until this issue is addressed, don’t think I’d be able to recommend this product. Especially knowing the creator directly discounts something so provably true.
