FAQ’s

What types of masks do you produce?

– Surgical masks for single use, in non-woven fabric (TNT), all of type IIR;

–  Surgical masks washable / reusable (40 washes) in fabric 100% polyester all of type IIR;

– Community masks washable / reusable some with 25 washes and 40 with others.

 

 

What is the standard of your masks?

Our surgical masks comply with the European standard EN 14683:2019.

This standard included several tests, such as the “Bacterial Filtration Efficiency” (BFE), the “Pressure Differential” ie the respirability of the mask, the “Resistance to splashes” and the “Bacterial load” (Bioburden) that checks the mask’s hygiene status.

Community masks comply with both the European standard EN 14683:2019 and CWA 17553: 2020, which has just come into force, where the difference is that the “Particle Filtration Efficiency” test (PFE) appears.

 

 

Do your masks meet the EN149 standards?

No, because they are NOT PPE – Personal Protective Equipment masks. Although there are common tests such as PFE – Particle Filtration Efficiency, and breathability.

 

 

What is the legal framework for your masks?

Surgical masks comply with the European directive 93/42/EEC, as they are medical devices Class I and must have notification to our national organization INFARMED.

Community masks comply with CWA 17553: 2020 and notify the national entity ASAE of the placing on the market.

 

 

What is the level of filtration of your masks?

Our surgical masks are of the IIR type, with a bacteria filtration above 98%, breathability (pressure differential) below 60 KPa and resistance to splashes (R).

 

 

Are your masks of the type FFP1, FFP2, FFP3?

These designations are the classification of PPE – Personal Protective Equipment’s masks. Our masks are not PPE, they are surgical or community masks that have different classification.

 

 

What is the difference between surgical mask (medical) and respiratory protection mask?

 

Medical masks (our masks)

The main function of a medical mask is to retain the saliva droplets and respiratory tract secretions emitted by the user and to protect the environment and / or other people.

Used by the caregiver, it avoids contamination of the patient and the environment.

Used by the patient in a contagious state, it avoids contamination of people around him and the environment.

In the “flu pandemic” plan, it is recommended for two populations:

– sick (possible or confirmed cases),

– people in a closed place, such as transport and other public places.

 

Respiratory masks

Respiratory protection masks can also be used in the context of a pandemic but are more used by workers in a work environment where there is contamination of the environment (dust, gases, liquids, paints, or biological contaminants). They can be used in hospitals or whenever justified. However, these masks have their own filters, depending on the medium in which they are used.

 

 

Are FFP masks more efficient than surgical or community masks?

In terms of filtration, our surgical masks are equal or superior to FFP, as they have a “Bacterial Filtration Efficiency” of 99%, even after washing. However, EPI’s masks have greater face sealing.

In terms of breathability, our surgical masks also have advantages, as they have values well below the maximum limit. FFP masks which due to their physical structure, only allow use for a maximum of 4 hours. With Hosp Protect masks, there is no such limit, as there is no accumulation of carbon dioxide inside the mask.

 

 

By which laboratory were your masks tested?

Some of our surgical masks have been tested by the AITEX laboratory (Spain) and other masks have been tested by the EQUILIBRIUM laboratory (Portugal). Regarding community masks, some references were tested by AITEX (Spain) and IFTH (France), other references were tested by CITEVE (Portugal).

 

 

Are masks marked with CE?

Our surgical masks are CE marked.

The community masks have the mandatory designation “Community facial cover CWA 17553: 2020”.

 

 

What is the difference between the “Particle Filtration Efficiency” test (PFE) and the “Bacterial Filtration Efficiency” test (BFE)?

Particle testing consists of aerosol spraying of microparticles (size 0.3 to 3 micrometers)

The bacteria test consists of the aerosol projection of live bacteria Staphyilococcus aureos (size of approximately 0.6 to 7 micrometers)

Efficiency is measured by the % of particles/bacteria that does not pass the mask barrier.

 

 

They have reusable masks of 40 and 25 washes. Do you want to have masks with the possibility of more uses?

We already have 40 washes guarantee for M1, M2, MK, P1.2, PK1.2 masks and 25 washes guarantee for A2.1 and A2.2. And with very good results in terms of filtration efficiency and breathability. So, on this side, there would be no problem doing more tests to prolong the uses, but we already think it would interfere with the normal durability of textile articles. So, we will not do more tests for a greater number of uses.

 

 

Is there a traceability of your masks?

All lots are inscribed on the packaging label, allowing immediate traceability.

 

 

Is it possible to change your label?

Label has mandatory information. However, it can be customized with your own brand if you wish.

 

 

Are your masks hand and/or machine washable?

Yes, following the information in the technical sheet.

 

 

What American standard is close to EN14683:2019?

ASTM F2100-19 is equivalent to EN 14683: 2019.

 

 

Can I customize my mask?

Yes, you can put a logo, design, photo or embroidery. However, you must always use the mask base of your choice. In other words, you can create a decorative element, but you cannot change the elements of the mask.

 

 

What kind of treatment do your masks have?

All of our textile masks have antibacterial treatment, which allows the mask to be sanitized for longer, avoiding unpleasant odors. An additional antiviral treatment can also be applied, which allows inactivating the virus, namely those of the Corona family, in contact with the mask.

 

 

What are the most sustainable masks?

FFP masks are for single use (generally) and are not recyclable. Our masks, due to the high number of reuses, become a sustainable product. In addition, they are made of 100% polyester, a recyclable fiber.
