How to Protect Yourself and Your Family from Pollution?

Assuming that you are healthy and pollution can’t possibly harm you is the biggest misconception because pollution affects each one of us, and we do not even realize it until it’s too late. Here’s what you can do to keep your family and yourself protected:

  1. Be mindful that your health can get affected by pollution too, and avoid doing things that add to more pollution.
  2. The elderly and children are prone to lung and other diseases, so make sure they do not go out during days when the pollution level is too high. You can check pollution levels online or buy a meter for this.
  3. You can get an air purifier to make sure that at least the air that you are breathing indoors is free of toxins.
  4. Avoid high-traffic areas and do not plan outdoor activities near such areas.

Air Purifiers

An air purifier would serve a double purpose.

First of all, an air purifier is always equipped with an air quality sensor.

Thanks to its own air quality index, the air purifier would let you know if and how much the air in your surroundings is polluted.

Of course, the air purifier is also capable of cleaning the air and removing pollution.

Air purifiers work thanks to filters: they suck in air, they let it pass through filters that can retain pollutant particles, and also blow clean air back into the room.
