Respirators, especially during the COVID-19 pandemic, became an important protective aid to our health. These filter half masks protect the wearer’s respiratory system by effectively covering the nose and mouth to prevent the penetration of viruses, bacteria, aerosols or dust particles. However, the current market offers several types and classes of respirators and it can be difficult for the average user to quickly find their way around this wide range. That is why we will briefly introduce you to individual types of respirators.

respirator without exhalation valve
Respirators are divided into three classes depending on the size of the airborne particles they are able to filter. The degree of protection of the wearer is therefore determined by the filtration class, which is the most important factor in choosing the right 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 they can filter particles with a size of 0.11 µm (particle size of coronavirus COVID-19), they provide us with 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 five 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.
respirator with exhalation valve
Customers can purchase a respirator with or without an exhalation valve. What is the difference between them?

The main advantages of a valve respirator are:

Easier exhalation and subsequent faster exit of warm exhaled air through the valve
Lower risk of fogging the glasses due to faster departure of warm air
The valve helps reduce material wetting
Fan respirators, however, have one major disadvantage:

If the wearer of the valve respirator is already infected with COVID-19, then the virus spreads freely into the air, as the valve does not contain any protective filter. However, if we want to protect other people and not just their health, it is better to wear a respirator without a filter, which significantly reduces the risk of virus transmission.

respirator with replaceable filters
These more expensive filter half masks made of silicone or other plastic materials can be used repeatedly thanks to replaceable filters.
