HOW DOES THE RESPIRATOR WORK?

Respirators help protect our airways from the penetration of microorganisms and harmful particles. How does such a respirator work and what does the designation FFP mean?

Respirators protect our respiratory organs from smoke, dust, aerosols and microorganisms and thus provide us with effective protection against COVID-19 infection. Their protective function is standardized in Europe according to EN 149. The product itself should also be provided with the necessary certificate proving that it has passed safety, efficacy and quality tests.

THE RESPIRATOR IS BASED ON A GOOD FILTER

Základem je dobrý filtr

The basis is a good filter
The respirator can be made of different filter materials, which have one thing in common – they are able to capture the appropriate amount of harmful particles from the air. An effective filter is therefore the most important part of a respirator. You can check its quality not only at the dealer himself, but also at home by cutting the used respirator and checking the filter.

RESPIRATOR CLASSES BY EFFICIENCY
Respirators are manufactured in three filtration classes: FFP1, FFP2 and FFP3, while the abbreviation FFP itself comes from the English term “Filtering Face-Piece”, which means a filter mask for the face.

Before buying it, it is necessary to know what the respirator should be used for (ie what it should specifically protect us from), and then adjust your choice accordingly. If you want to protect your health from COVID-19 infection, choose respirators from either the FFP3 or FFP2 protection class (but you must be more careful with this class, because coronaviruses can only catch some of the respirators in this class). If you work in a dusty environment and want to protect your airways, it is enough to choose an FFP1 class respirator.

FFP1 respirator
These respirators protect against larger dust particles and aerosols, so they are used, for example, in construction, but they will not protect us from COVID-19! Class FFP1 respirators must trap at least 80% of the airborne particles.
FFP2 respirator
They protect against finer dust particles and aerosols, and if these respirators can filter 0.11 µm particles (COVID-19 coronavirus particle size), they provide effective protection against the virus. Class FFP2 respirators must capture at least 94% of the airborne particles.
The FFP2 class protective respirator from the Czech manufacturer Good mask provides just such effective protection against coronaviruses. Thanks to the filter layers and effective sealing nasal reinforcement, it is able to protect its wearer by more than 95% from the above-mentioned dangerous components.
FFP3 respirator
It serves as the most effective protection against bacteria, viruses (thus also against a new type of coronavirus), fungal spores and fine toxic particles. Unfortunately, there is a shortage of these respirators in our market. Class FFP3 respirators must trap at least 99% of the airborne particles.
HOW TO HANDLE THE RESPIRATOR CORRECTLY?

In order for the protective function of the respirator to be as effective as possible, the basic rules of wearing it must be observed:

Disinfect your hands before wearing the respirator.
Put on the respirator so that the nose clip is at the top center.
Before mounting, we recommend shaping the nose clip by gently bending it into an inverted “U” shape. If necessary, crease the nose clip directly on the face.
Apply the respirator so that it covers your nose, mouth and chin.
A properly fitted respirator is close to the face, so always put it on your shaved face.
After attaching the respirator, do not touch the front of the respirator with your hands to avoid possible contamination with your hands.
Always remove the respirator by its rear straps. Do not touch the front with your hands.
If you have a disposable respirator, discard it and wash your hands after using it.
If you use a respirator with a replaceable filter, be sure to change the filter regularly.
