If you live in a city like Delhi, you know all too well how air pollution can turn stepping outside (or even keeping your windows open all day for ventilation) into a health hazard. That's why wearing a mask every day has become second nature for many of us. But did you know that your masks, especially N99 or N95 types, only work if you use them right? A mask that's dirty or worn incorrectly can actually collect bacteria and moisture, putting you at risk instead of keeping you safe. To help you get the best protection, here is a must-follow survival checklist for making sure you are protecting yourself against air pollution.
The pre-use checklist for choosing the right masks is key because of PM2.5 and PM10 particulate matter pollution. Both cloth and surgical masks offer minimal protection against smog and raging air pollution. The main differentiating factor while comparing masks lies in their ability to properly secure the mouth, nose, and correctly conceal the nose. But, make sure it's comfortable as masks need to be worn for long periods.
Inspection
There are various mask hygiene tips to ensure proper protection from smog and air pollution. These range from choosing which mask to wear, how to store it, and how to dispose of it safely.
There are always pre-handling, mid-use, and post-handling of mask hygiene rules that can ensure proper mask hygiene.
While using masks, the manufacturer's guidelines need to be followed if provided. If no guidelines exist, N95 or N99 masks generally last for 40 hours of extended use. But this is drastically reduced in heavily polluted cities like Delhi, Noida, Faridabad, and Ghaziabad.
The Moisture Test: If the inside of the mask becomes damp (from talking, breathing, or sweating). In addition, if the outside of the mask is visibly dirty, then you need to discard it immediately. This is because damp masks breed bacteria and mold.
Not all masks are reusable. The masks that you use need to be labelled as reusable, and only then you can use the mask for a longer duration. Be sure to never wash disposable masks with filters, as washing destroys the electrostatic charge that catches PM2.5 and PM10.
Drying:
When the mask has been worn for long periods of time, then you are safely removing the mask. This can be done by only touching the ear loops or head straps.
When discarding a single-use mask, place it in a plastic bag, tie it securely, and dispose of it in a closed dustbin to protect waste pickers from exposure to contaminants.
Masking is your shield, but hygiene is the key to maintaining that shield's integrity. Be diligent, check your mask often, and prioritize clean handling to breathe more safely this pollution season.
A balanced diet helps build your immunity and protects you from health issues that may be posed by the poor air quality. Certain nutrients can help boost your immunity. Here are the best nutrients for immunity and their food sources:
