How does PM2 5 work?

PM2. 5 refers to particles that have diameter less than 2.5 micrometres (more than 100 times thinner than a human hair) and remain suspended for longer. These particles are formed as a result of burning fuel and chemical reactions that take place in the atmosphere. 5 in the air.

5 levels are high:

  1. Avoid using anything that burns, such as wood fireplaces, gas logs and even candles or incense.
  2. Keep the room clean – but don’t vacuum unless your vacuum has a HEPA filter.

  5. When air quality improves, open the windows and air out your home or office.

How does PM2 5 affect air quality?

How can PM2.5 affect my health? Particles in the PM2.5 size range are able to travel deeply into the respiratory tract, reaching the lungs. Exposure to fine particles can cause short-term health effects such as eye, nose, throat and lung irritation, coughing, sneezing, runny nose and shortness of breath.

How effective are PM2 5 filters?

How often should you change a PM 2.5 filter?
