Medical masks - faq

How medical masks differ between one another?

Depending on the purpose, there are the following types of medical masks: type I, type II and type II R. Each type differs with respect to material filtration efficiency (BFE), resistance to liquids and resistance of exhaled air which affects the comfort of use.

What are medical masks intended for?

The main purpose of medical masks is to protect the environment of the medical staff against viruses. This function is ensured by means of special filtering material which stops the droplets of the exhaled air. Medical mask should fit tightly to the face so as to protect its user (to a small extent). The II R medical mask additionally retains fluids and liquids.

Who should use medical masks?

Medical masks should be used by medical staff in any space in which direct or indirect contact with the patient may occur. This way, the risk of transmission of viruses by droplets is limited to a minimum.

How tight are medical masks?

Unfortunately, the medical mask is not completely tight, which is why it is so important that it is correctly worn so that it adheres closely to the face.

How long can a medical mask be worn?

After some time, the filtering material in the medical mask becomes damp and no longer provide protection. Therefore, medical masks are disposable products which should be changed when they become wet. Regardless of how wet the mask is, it should be replaced no later than 3–4 hours after wearing it.

What are the differences between medical masks?

Depending on their intended use, medical masks are divided into types: type I, type II and type II R . The individual types differ from each other in such elements as: the effectiveness of the filter material (BFE), resistance to soaking of liquids and the resistance of exhaled air, which affects the comfort of using the mask.

How to distinguish a safe, all-standard medical mask from a regular non-woven one? What should be verified before buying?

Currently, there are a number of “medical” masks on the market, often at a good price. Unfortunately, many of them do not meet any standards for medical products. The requirements for medical masks are described in the EN 14683 standard. They refer both to the product itself (mask) and to the manufacturing process.
Before buying, verify the following:
Does the package bear the EN 14683 marking and the CE mark?
Has the product been registered in the Office for Registration of Medicinal Products, Medical Devices and Biocides? (VAT on medical masks is 8% while VAT on non-medical masks is 23%)
Have the manufacturer conducted and is willing to present the results of microbiological tests performed by an approved laboratory?
Does the manufacturer have a document confirming that medical masks are manufactured in accordance with the ISO cleanroom standards required by law?
