In a hot and humid working environment, poor ventilation or heavy labor, using an anti-smog mask with a FFP2 Actived Carbon Folding Mask with Valve can help you feel more comfortable when you exhale. The principle of the breathing valve of the anti-haze mask is that when exhaling, the positive pressure of the exhaust gas blows open the valve plate to quickly remove exhaust gas from the body and reduce the sultry feeling when using the anti-haze mask, and the negative pressure during inhalation will automatically reduce The valve is closed to avoid sucking in pollutants from the outside environment.
It can be seen that the anti-haze masks with FFP2 Actived Carbon Folding Mask with Valve are more suitable for harsher use environments and are more beneficial to human breathing. An anti-haze mask with an exhalation valve can quickly expel the exhaled hot and humid air out of the mask. For a mask without an exhalation valve, the exhaled hot and humid air has to go out of the filter cotton, which will easily wet the filter cotton, causing bacteria to multiply and increase breathing resistance, which is not effective. In order to ensure the protective effect, it is recommended to purchase anti-smog masks certified by GB. Some so-called experts say that good masks cannot breathe smoothly, which is an old calendar. The current dust-proof mask adopts the principle of electrostatic adsorption, which can prevent ultra-fine dust, and has a high dust-holding degree, and breathing is smooth. It can be worn by the elderly including heart disease and the elderly.
Anti-smog masks. Masks with an exhalation valve, such as N95 FFP2 Actived Carbon Folding Mask with Valve activated carbon masks, meet the N95 mask standard. Anti-smog masks with breathing valves are more suitable for use in harsher environments and are more beneficial to human breathing. In hot and humid working environments, poor ventilation, or heavy labor, the use of activated carbon masks with FFP2 Actived Carbon Folding Mask with Valve can help you feel more comfortable when you breathe out.
The principle of the FFP2 Actived Carbon Folding Mask with Valve of the anti-smog mask is that the positive pressure of the exhaust gas blows open the valve plate during exhalation to quickly eliminate the exhaust gas from the body and reduce the sultry feeling when using the dust mask. The negative pressure during inhalation will automatically reduce The valve is closed to avoid sucking in pollutants from the outside environment.
The exhalation valve of the mask has the function of quickly expelling hot and humid air.
Wearing a PM2.5 mask FFP2 Actived Carbon Folding Mask with Valve means that a large amount of hot and humid air is exhaled. If there is no exhalation valve, most of it will be discharged through the filter cotton. Because the outside air is cold, the hot and humid air will condense into water droplets, which will quickly wet the PM2.5 mask. , Resulting in decreased protective effect and increased respiratory resistance. Therefore, it is better to have an exhalation valve.
