The ongoing pandemic has made face masks a necessity. However, storing face masks can be tricky. The CDC recommends storing damp or contaminated masks in plastic baggies. However, this is wasteful and not environmentally friendly. It is also not advisable to store masks in plastic bags as they can create condensation, leading to bacterial and mould growth. Paper bags are a better alternative as they allow masks to air out while keeping the outside of the mask from touching other surfaces.

Face masks should be stored in paper bags, not plastic bags, to allow masks to dry out between uses
Face masks have been a necessity ever since the COVID-19 pandemic began. While wearing a face mask is crucial, it is equally important to store it properly. The CDC recommends storing damp or contaminated masks in plastic baggies. However, this is not the ideal way to store face masks as it can lead to the growth of bacteria and mould.
The primary purpose of wearing a face mask is to prevent the spread of COVID-19. When you store a damp mask in a plastic bag, you create the perfect breeding ground for microorganisms. Additionally, the moisture in the bag can cause the mask to become mouldy. Therefore, it is advisable to avoid storing face masks in plastic bags.
Instead of plastic bags, it is recommended to use paper bags to store face masks. Paper bags allow the masks to dry out between uses, preventing the growth of bacteria and mould. They also help to keep the outside of the mask from touching other surfaces. By allowing the mask to air out, the risk of surface transmission of COVID-19 is reduced.
When using a paper bag to store your face mask, ensure that the bag is clean and sealable. Carefully fold the mask so that the outer surface is held inward, reducing contact with the outer surface during storage. Always store the bag in a clean, isolated place, and wash your hands after handling the mask.
In conclusion, while plastic bags may be convenient for storing face masks on the go, they can create an environment conducive to the growth of microorganisms. Paper bags, on the other hand, allow the masks to dry out and reduce the risk of surface transmission of COVID-19. Therefore, it is recommended to store face masks in paper bags, not plastic bags, to ensure proper hygiene and safety.

Plastic bags are recommended for storing damp or contaminated masks, but only until they can be washed
It is recommended to store damp or contaminated face masks in plastic bags, but only until they can be washed. This is because a damp and dirty mask is a contamination hazard and should not be used again until cleaned. The CDC recommends storing dirty masks in plastic bags, sealed against the environment. However, it is important to note that this is only a temporary solution as the sealed, damp environment of a plastic bag can be a breeding ground for microorganisms. Therefore, masks should be washed as soon as possible.
When removing a face mask, it is important to follow proper handling instructions. This includes folding the mask with the inside surface contained to prevent the outside of the mask from touching other surfaces. It is also recommended to wash your hands after handling a used mask. Once the mask is folded, it can be placed directly into a plastic bag and sealed. The bag should then be stored somewhere safe and isolated until the mask can be washed.
While plastic bags are a convenient option for storing damp or contaminated masks temporarily, they may not be the most sustainable choice. As single-use plastic, they contribute to waste and cannot be easily recycled. Additionally, sending a contaminated mask for recycling can put workers at risk. As an alternative, some people choose to use paper bags, as they allow the masks to air out while keeping the outside of the mask from touching other surfaces. However, paper bags may not be as effective at preventing fomite transmission, where a contaminated surface leads to the spread of COVID-19.
To reduce waste, some people opt for reusable storage options such as soft-shelled baggies with zippers or hard plastic cases. These cases can be sanitised and used to store both clean and dirty masks. However, it is important to note that once a dirty mask is placed inside, anything inside the case is considered contaminated. Therefore, it is recommended to wash masks as soon as possible and have multiple masks available for rotation.

Face masks can be stored in sealable plastic bags, but only if they are completely dry
If you are using a plastic bag to store a face mask, it is important to follow proper handling instructions. Firstly, fold the mask with the inside surface contained, so that the inside of the mask does not come into contact with other surfaces. Then, place the mask directly into a plastic bag, seal it, and store it in a safe and isolated location. Wash your hands before and after handling the mask to prevent contamination.
It is worth noting that some sources suggest avoiding plastic bags altogether due to the potential for condensation to build up inside the bag, which can lead to the growth of bacteria and mould. Instead, it is recommended to use a storage container that is dry and breathable, such as a paper bag or a mesh cloth bag. These alternatives allow for better air circulation and help keep the mask dry.
Additionally, it is important to wash or sanitise your hands after touching any surface that the mask has come into contact with. This includes surfaces like tables or countertops, as well as your hands themselves. By practising good hand hygiene, you can reduce the risk of second-hand contamination, which can occur when touching your nose, eyes, or mouth directly after handling a contaminated surface.
In summary, while face masks can be stored in sealable plastic bags, it is crucial to ensure that the masks are completely dry to prevent the growth of bacteria and mould. Proper handling and storage procedures, as well as good hand hygiene, are essential to minimise the risk of contamination when using and storing face masks.

Plastic bags are useful for storing multiple face masks when on the go
Plastic bags can be useful for storing multiple face masks when on the go, but there are some important considerations to keep in mind. Firstly, it is generally recommended to avoid storing face masks in plastic bags if they are damp or wet, as the enclosed environment can promote the growth of bacteria and mould. Instead, it is advised to let the masks air dry before placing them in plastic bags or opting for breathable storage options like paper or mesh cloth bags.
However, if you are carrying multiple face masks and need a quick and convenient storage solution, plastic bags can be practical. It is suggested to have several plastic bags on hand, equal to the number of masks you are bringing. This way, you can place each used mask in its own sealed plastic bag, preventing cross-contamination and keeping the masks isolated until you can wash them. This method can be particularly useful when running errands or during long shifts, allowing you to swap masks throughout the day without mixing clean and used masks.
Additionally, labelling the plastic bags can be helpful, especially if you are using disposable masks. This way, you can keep track of which masks have been used and avoid potential confusion. It is worth noting that this practice can create waste, as you are disposing of both the masks and the plastic bags. However, it can be a temporary solution when you are out and about and need a quick storage option for multiple face masks.
While plastic bags can be useful for storing multiple face masks temporarily, it is important to follow proper handling and storage procedures. Always wash your hands after handling used masks, and make sure to wash the masks as soon as possible to prevent any contamination. Additionally, ensure that the plastic bags are sealed tightly to avoid any leakage or exposure.

Plastic bags can be used to store face masks in the freezer
- Disposable Face Masks: If you are using disposable face masks, such as N95 respirators, you can store them in plastic bags in the freezer. This method is particularly useful if you want to reuse the masks. Freezing the masks can help kill any bacteria or viruses that may be present. However, it is important to let the masks dry completely before placing them in the freezer to prevent moisture buildup, which can lead to mould growth.
- Contaminated Masks: In cases where your face mask is damp or contaminated, the CDC recommends using plastic bags for storage. Fold the mask with the inside surface contained, seal it in a plastic bag, and then place the bag in the freezer. This method helps isolate the mask and prevent further contamination until you can wash it.
- Store-Bought Face Masks: Some store-bought face masks, especially those with vitamin C and vitamin A, require airtight storage to prevent the ingredients from degrading. If the original packaging is not airtight, you can transfer the mask to a plastic zipper bag, remove the excess air, seal it, and then store it in the freezer.
- Homemade Face Masks: If you prepare homemade face masks, you can store the leftovers in a plastic bag in the freezer. This helps extend the shelf life of the product and preserves its freshness.
When using plastic bags to store face masks in the freezer, it is important to follow proper handling and hygiene practices. Always wash your hands before and after handling the masks. Additionally, ensure that the masks are completely dry before sealing them in the plastic bags to prevent moisture buildup and mould growth.
