A mask should be worn when the air quality is bad outside because it affects health. If there is a chance of long exposure to poor air quality people should be careful of spending too much time breathing poor air. A mask can also be worn to prevent yourself from getting sick.
This corresponds to different levels of air pollution for healthy people and the most vulnerable groups: people who suffer from chronic lung or heart disease, elderly, pregnant, and children.
N95 masks are not needed for short exposure, or when the air quality is good. N95 masks are also not needed in an indoor environment if the environment is filtered using indoor air purifiers.
There is a range of masks suitable for all activities and environments adapted to the use: in or out of the city, running, walking, commuting, sports and leisure, allergy relief, or for the work place. The more adapted a mask is to the activity and needs of the user, the more effective the protection from the effects of air pollution will be.
The most important thing about the prevention of pollutants or other harmful substances is to understand that air can be bad, and to have tools in place to battle it. During an epidemic like Covid-19, we are all very worried about getting sick. The Personal Protection Equipment (PPE) that people are sold is often not helpful. We need to understand that the air we breathe can be filled with harmful particles at any time. We also need to know that prevention of substances entering our system can happen very quickly and without us even knowing. The key is to protect yourself from hazardous particles by filtering your indoor air, minimizing contact, cleaning hands frequently, and wearing a mask that is fitted. At AryMask we ensure that you get a mask that fits.
Here 3 doctors offer their knowledge about surgical VS ffp3 certified masks. They don’t however mention that even a fitted mask cannot prevent those who are around you from getting sick. Any mask with a valve for that matter will allow cough droplets to escape into your surrounding.
