This 'medium' sized, type 10B, autoclavable mushroom filter patch bag measures 5" x 4" x 18"". Our official Unicorn Bags feature gusseted sides and a 5.0 micron (type B) filter that measures 1.5-inch x 1.5-inch. The 5.0 µm filter is composed of laminates of non-woven polypropylene with PTFE. This bag is composed of 3.0 mil thick polypropylene plastic.
This 'medium' sized bag can comfortably hold three (3) quarts worth of material (in volume), while still leaving enough room to perform any standard procedure on the bag without the contents (grain/substrate) compromising/encroaching on the filter patch. The 5.0 µm filter offers the highest amount of gas exchange of any of our filters which makes this bag ideal for fruiting mushrooms inside of. These bags make great fruiting chambers for many species of mushrooms. Additionally, these bags can be used for substrate production. The 5.0 µm filter is not recommended for grain spawn production, as the larger 5.0 µm pore size of the filter is not as effective filtering contaminants when compared to the 0.2 or 0.5 µm filters that we offer. The filter is located at the top of the bag, which allows for more grain or substrate to be loaded into the bag when compared to other bags on the market. The microporous filter patch allows for filtered gaseous air exchange while keeping contaminants out. You will need to seal these bags with an impulse sealer or mushroom bag clamp.
