How does a still air box work?

A still air box, also known as a SAB, is a type of enclosed workspace used in mycology to create a sterile environment for working with cultures or inoculations. The box is designed to prevent outside contaminants from entering while allowing the user to introduce their own sterile equipment and materials.

The basic design of a still air box includes a transparent enclosure, usually made of clear plastic or glass, that is large enough to accommodate the materials being worked with. The enclosure is typically mounted on legs or placed on a raised platform to allow the user to work at a comfortable height.

To create a sterile environment within the box, the air inside is allowed to settle and become still. This minimizes the circulation of airborne particles and microorganisms, which could potentially contaminate the materials being worked with. To further reduce the risk of contamination, the box is usually sterilized with a disinfectant or sterilizing agent before use.

The user can then introduce their own sterile equipment and materials into the box through small openings or ports, which are often fitted with gloves to allow for manipulation without risking contamination. The user can then carry out their work inside the box, taking care to avoid any contact with the sides or top of the enclosure, which could potentially release particles and microorganisms into the environment.

I. Features and Benefits of a Premium Still Air Box

Here are some of the key features and benefits of the Mushroom Still Air Box:

1. Huge Working Area

One of the standout features of the Mushroom Still Air Box is its large working area. Unlike other SABs on the market, this box provides ample space for you to work in without feeling cramped or confined. This is particularly important when you're working with multiple items or conducting more advanced techniques like agar transfers or genetic modification.

2. Easy Access to Side Panels

The side panels of the Mushroom Still Air Box open easily with a zipper, making it simple to place your items inside and access them when you need to. The arm holes in the box also make it easy to work inside the box with your items while maintaining a sterile environment. The convenience and ease of use of this SAB are major benefits for both novice and experienced mushroom growers alike.

3. Affordable and Portable

Creating a sterile environment for mushroom cultivation doesn't have to break the bank. SABs are an affordable way to ensure a sterile environment during cultivation. The Mushroom Still Air Box is a great investment because it offers all the benefits of a high-quality SAB at an affordable price. Plus, it's lightweight and collapsible, so you can easily take it with you wherever you go.

II. Advanced Techniques with Still Air Box

If you're interested in more advanced mushroom cultivation techniques, a SAB is essential.

Here are just a few of the techniques you can try with a SAB:

  1. Working with agar transfers, cloning & testing: These techniques involve transferring mycelium to agar plates to isolate and propagate individual strains.
  2. Transferring mycelium to grow bags: Once your mycelium is growing on agar, you can transfer it to a grow bag for further development.
  3. Cloning your favorite big (or weird) looking mushrooms: With a SAB, you can clone your favorite mushrooms to create new strains with desirable characteristics.
  4. Injecting grow bags (if you want to be extra sterile): Using a SAB makes it easy to inject spores or mycelium into grow bags without introducing contaminants.
  5. Mushroom Genetic modification (taught in our advanced grow course): With the right equipment and techniques, you can even genetically modify your mushrooms.

III. Alternatives to Still Air Box

While SABs are a great way to create a sterile environment, there are more expensive alternatives if you need an even higher level of sterilization. For example:

1. Cleanrooms

These specialized rooms are designed to maintain high cleanliness and sterility. They are commonly used in industries such as pharmaceuticals, biotechnology, and electronics manufacturing. Clean rooms typically use advanced air filtration systems, including HEPA filters, to remove particles and microorganisms from the air.

While cleanrooms offer the highest level of sterility, they can be expensive to build and maintain. The cost of a clean room can range from 10K to 1M USD, depending on the size and complexity of the design.

2. Laminar Flow Hoods

These hoods use a flow of filtered air to create a sterile environment. They are commonly used in laboratories, hospitals, and pharmacies for tasks such as compounding sterile medications and preparing tissue cultures. Laminar flow hoods are available in various sizes and configurations, from small benchtop models to larger floor-standing units.

While laminar flow hoods are less expensive than clean rooms, they can still be costly. Prices usually range from a few hundred to over a thousand dollars.

However, for most mushroom growers, a SAB is more than sufficient to create a sterile environment.


If you're serious about growing mushrooms, a Still Air Box is an essential tool to have in your arsenal. The premium Mushroom Still Air Box from Curative Mushrooms offers a large working area and easy access to side panels. It also offers portability, making it a great choice for anyone looking to create a sterile environment during their mushroom cultivation journey.
