Still Air Box vs Laminar Flow Hood for sterile environment?

The most recommended equipment to ensure a well clean and sanitized area are:

  1. a laminar flow hood or
  2. a STILL AIR BOX.

Deciding on a still air box or flow hood for mycology work is crucial, with each offering benefits and drawbacks. Available pre-made or DIY, your choice ultimately hinges on budget, experience, and time commitment.

The Laminar Flow Hood (Budget: 200-500$)

A laminar flow hood keeps a steady, one-way stream of HEPA-filtered air moving over your workspace. This helps keep dust, spores, and other contaminants floating in the air away from your work area.


Its main downside is the high cost, making it a significant investment for hobbyists. Despite this, its effectiveness in ensuring successful cultivation makes it a valuable tool for serious mycology enthusiasts.

Large laboratory-grade laminar flow hoods can reach prices up to $2000, while smaller versions are available around $200-500. In contrast, a SAB offers a more affordable alternative, potentially yielding similar results at a fraction of the cost.

Dive Deeper into the World of Still Air Boxes (SABs).

History and Origin

The Still Air Box (SAB) was born from the mycology community's need for an affordable cultivation tool, a response to the pricey laminar flow hoods.


Conceived in  online forums , the SAB democratized mushroom growing by offering a simple, cost-effective way to maintain a sterile environment, opening up the hobby to a broader audience.

The Advantages of the Still Air Box Over the Glove Boxes

Experimentation with glove boxes (rubber gloves attached in the arm holes) uncovered their limitations in managing air movement, essential for minimizing contamination. Their sealed nature often leads to a "piston effect," amplifying air currents and particles, thereby increasing the risk of contamination.


This understanding has led the mycology community to agree that the Still Air Box, with its better design, offers a more reliable way to keep conditions sterile.

Still Air Box vs Gloves Box

Is a still air box necessary?

Yes, Its design effectively limits the flow of air, ensuring that any potential contaminants stay settled on surfaces rather than becoming airborne particles.

How does a still air box work?

The Still Air Box is basically a plastic container with two arm holes designed based on principles of physics to create a workspace with very little air movement. Its design effectively limits the flow of air, ensuring that any potential contaminants stay settled on surfaces rather than becoming airborne particles.

Are still air boxes effective?

This reduction in air movement dramatically lowers the risk of contamination during the sanitization process, making it a critical tool for maintaining a sterile environment in mushroom cultivation.

How to clean and sanitise a still air box?

Wipe the interior with a cloth dampened with 70% isopropyl alcohol, allowing it to air dry for effective cleaning and sanitization.

Still Air Boxes : Today's Market Options (Budget: 40-80$)

If you're a beginner interested in diving into this hobby, you might seek a hassle-free option. While Still Air Boxes are readily available on the market, considering their price and features, they may not offer the best value for you. These products often don't provide substantial benefits over a basic DIY Still Air Box.

Increased Contamination Risk : Many of these models feature covered holes for hand integration, which can create air turbulence as you move your hands in and out (piston effect), particularly when sterilizing tools such as scalpels. This is by definition not STILL AIR and can increase your contamination issues.

Prone to Damage : These models consist of a thin plastic layer and a zipper, making them susceptible to damage. Likely, this design choice was intended to optimize shipping efficiency by minimizing volume.

Missing Sterilization Tool : Working within a still air box inherently involves using a sterilization tool; one is essential to the other. However, they are not typically sold together as a package.

Limited Visibility : Operating within a Still Air Box requires precise manipulations where accuracy is crucial. Yet, these units do not come equipped with lighting to improve visibility.

Still air box (SAB) DIY (Budget: 10-20$)

At Trippy Tek, we believe you'll find greater value in constructing your own SAB. It can be done more affordable than purchasing premade options available on the market, adding to the fulfilling experience of home mycology work.


The essence of this hobby lies in the joy of growing mushrooms from scratch—crafting your setup and engaging in hands-on work makes it uniquely rewarding. After all, there's a special satisfaction in building something with your own hands.

Basic Still Air Box DIY

How to make a still air box

Setting up a SAB is incredibly easy, requiring only a couple of steps:

And that's everything! You'll likely find all the required materials and equipment around your house or in your workshop.

Upgrade your SAB with these top accessories

LED light (Budget: 10$)

Adding a light source is simple yet effective. Placing a desk lamp above or installing LED strip lights inside significantly improves visibility through the plastic container. Given the precision required for our tasks, optimal lighting is crucial.

Elevated Wire Rack (Budget: 20$)

Another useful add-on is an elevated wire rack. This rack allows us to work above the area where contaminants are most likely to be found, mirroring the best practices of professional scientists.

Sterilize your scalpel with an induction sterilizer (Budget 35$ DIY / 130$ Pre-Built)

Many are moving away from flame sterilization to adopt a safer, more efficient method for sterilizing scalpel blades: the induction coil. This technique, utilizing electromagnetic fields, offers quick and safe sterilization.

Integrating it into your SAB creates a highly organized setup. You can purchase a ready-to-use model, though it may be costly, or opt to build one yourself for a more budget-friendly solution.

Still air box alternative materials

DIY Still Air Boxes vary greatly in quality, from basic to expertly crafted. The typical choice of material is a plastic container, though plexiglass versions offer durability and aesthetics at a higher cost without significant benefits.


Some opt for a budget-friendly approach using cardboard and saran wrap (for visibility), aiming for an inexpensive, collapsible design that saves space when not in use.


Number 1 Mistake to Avoid with Your Still Air Box

Keep in mind, most tasks in the SAB involve a scalpel, especially for agar work. Ensuring the blade is sterile is crucial. You could use a new blade each time or opt for disposable scalpels. Alternatively, you can sterilize blades by heating them until red hot, making them ready for reuse.


While some opt for UV light sterilization inside the SAB as a precaution, it's often more than necessary for our purposes.

Some people use an alcohol lamp, butane torch, or lighter to FLAME STERILIZE their scalpel. However, using OPEN FLAMES can be dangerous, especially if done INSIDE THE SAB where 70% ISOPROPYL ALCOHOL fumes may create a flammable atmosphere.

There have been many reports of SABs being damaged due to explosions from this practice. It's a lesson best learned from others rather than experiencing it firsthand.
