The easiest and cheapest way to build a laminar flow hood

Many customers who grow mushrooms ask us about air purification devices. Some of them ask about Fan filter units or Laminar flow cabinets. In many cases, purchasing these devices costs a lot because these devices are used in strict industrial requirements. For mushroom cultivation, there is no need to use these expensive facilities, we will introduce you to some simple and feasible filtration methods.

Just need a HEPA filter and a fan, and then build a box yourself, you can have a recommended laminar flow device, and you can go to YouTube to learn how to make such a device. You can easily buy cabinets and fans locally. For HEPA, we are very advantageous in this regard. You can buy from us and get the best price.

You may already know a lot about this, so let’s introduce you to another method that is very popular recently.

A simple laminar flow cabinet made of fan-powered HEPA filter

This is a simple Laminar flow cabinet built with aluminum alloy square tube and Fan-powered HEPA filter. Its laminar airflow is from top to bottom. The built-in H13 high-efficiency filter can filter out more than 99.97% of fungi, bacteria, dust, etc. For mushroom cultivation, this is completely sufficient.

Aluminum alloy square tubes are fixed by metal screws. We will cut these square tubes to the appropriate length, and then the customer installs them step by step according to the instructions. This does not take a long time, usually, an hour is good. Install. There will be anti-static PVC cloth on the side. Use glue or screws to fix it around to ensure that no contaminants enter the work area. Fan-powered HEPA filters will continuously blow out high-purity airflow, and mushroom inoculation can be completed well in this high-purity environment.
