Mask: This may be a disposable medical device (surgical mask) or personal protective equipment (PPE mask) worn by caregivers and/or carriers of infectious diseases. Depending on the type, they can prevent droplets or airborne diseases. Standards and levels of protection stipulate their suitability for viruses such as the coronavirus. They are also known as masks, mask, chinstraps, masks, etc.

PID mask: Any equipment or tool intended to be used or worn by a person to protect him/her from one or more health and safety risks.

Filtering mask: Designed to prevent contamination of the user, it is especially important for medical personnel, due to the personal risks they face and community risk if they become a source of infection for asymptomatic patients.

Fabric mask: Not considered resistant to respiratory viruses. And, in the field of employment, they should not be promoted or used. Moreover, “homemade fabric masks” do not meet standards for personal protective equipment or medical equipment.

Surgical mask: This is a disposable medical device. It prevents infectious agents from being spread by droplets. However, they cannot prevent airborne infectious agents. Therefore, they will not prevent users from being exposed to possible virus contamination.

Recommended for patients and case studies diagnosed with VIDOC-19. These patients should be isolated from other patients and wear masks during all transfers.

Hygienic Mask: These non-medical masks can be made from different textile materials, such as cotton fabric. They are not considered medical products or PPE. And they do not stick to the face.

They are suitable for people without symptoms. People who are not comfortable using surgical masks or filters according to established recommendations.

Reusable mask: In the case of hygiene of the mask, the cleaning and drying of the mask must comply with the manufacturer’s recommendation. Check after each cleaning visually to avoid any damage.

Non-reusable mask: They are for single use only. Check manufacturer’s instructions for durability and when to dispose of the mask.

Mask with valve: Promote breathing and prevent condensation, recommended for long term use. Because they cannot filter the air exhaled by the user, patients with infectious respiratory diseases should not use valve masks.

Dual mask: On the one hand, they provide protection for the user of biological aerosols, while reducing the transmission of vectors from the same person to the work area. In this case, they must comply with the legal requirements of PID and PS.

Dispose of after completing a task or remaining in a contaminated area

FFP1: The minimum filtration efficiency is 78% and the leakage rate to the outside is 22%, which can prevent non-toxic and non-fibrous waste generated by dust or aerosol. It avoids inhalation of these and unpleasant odours.

They are usually used to prevent particles of inert materials and are therefore not recommended for medical use.

FFP2: Minimum filtration efficiency is 92%, and leakage to the outside is 8%. As mentioned above, it can provide protection against non-toxic residues and also against fibrous elements. In this way, it prevents us from inhaling toxic liquid dusts, aerosols and smoke.

FFP2 types of masks are usually used against medium and low toxicity aerosols. Therefore, users will be protected from VOC-19 infection. In addition, they can prevent transmission from users to the outside.

FFP3: The minimum filtration efficiency is 98%, and the leakage to the outside is 2%. It fights all kinds of dust, smoke and toxic aerosols. It is effective against bacteria, virus and fungus spores.

It is used against very toxic aerosols. Users will be protected from COVID-19 infection.

N95: This is a particle filter mask that complies with the N95 standard of the National Institute of Occupational Safety and Health. The name N indicates that the oils are not filtered, and the reference number 95 indicates that at most 95% of the air particles are filtered. Also known as polypropylene non-woven fabric.

They are commonly used in work environments where harmful and mutagenic particles are present, such as in metallurgy, garbage collection and construction.
