Air Pollution FAQs

According to the World Health Organization (WHO) air pollution is a major cause of disease and death in the world, contributing to 3 million premature deaths worldwide every year. It happens when gases and other substances, including particulates and biological molecules, are introduced into Earth’s atmosphere, harming humans, animals, plants and the whole ecosystem. It is a global issue and a serious health concern which needs to be attended to.

PM 2.5 – or fine particulate matter – is a mixture of extremely small solid and liquid particles present in the air that are not visible to the naked eye. They measure less than 2.5 micrometers in diameter, which is 30 times smaller than the human hair. Because of that, they can penetrate deep into our lungs and bloodstream, causing severe damage to the lung tissue, cardiovascular disease and premature deaths.

An Air Quality Index (AQI) is a number used by government agencies to measure the air pollution levels and communicate it to the population. As the AQI increases, it means that a large percentage of the population will experience severe adverse health effects. The measurement of the AQI requires an air monitor and an air pollutant concentration over a specified averaging period. The results are grouped into ranges, and each range is assigned a descriptor, a color code and a standardized public health advisory. You can check more about AQI here: AQI.in

PM10 is almost the same as PM2.5; the only difference is on it’s size. PM10 measures 10 micrometers or less in diameter.

The pollution sources in India – and in most Asian countries – are numerous and incompletely understood. That’s why each country has to have it’s own AQI values. The National Air Quality Index Standard (NAQI) in India was launched on 17 September 2014. The initiative constitutes part of the Government’s mission to introduce the “culture of cleanliness”, as the air pollution has been a huge concern in the country.

Like everywhere in the world, AQI value varies on a daily bases and it depends on which city you are in. But even though India has its own AQI standards, they are ranked as one of the highest: according to the World Health Organization, 10 of the top 20 most polluted cities in the world are in India, and ambient fine particulate matter (PM2.5) levels in Delhi rank among the highest levels measured in any city in the world – about 15 times higher than WHO’s guideline concentrations. That’s why it is very important to understand the air quality around you.

The AQI values represent the following status of air pollution :

  1. Good : 0 – 50
  2. Moderate : 51 – 100
  3. Unhealthy For Groups : 101 -150
  4. Unhealthy : 151 – 200
  5. Very Unhealthy : 201 – 300
  6. Hazardous For Groups : 301+

Air pollution causes a huge number of pollution-related diseases, including respiratory infections, heart disease, Chronic Obstructive Pulmonary Disease (COPD), stroke, lung cancer and, of course, the worsening of existing respiratory and cardiac conditions. Symptoms like allergies, difficulty in breathing, wheezing, coughing and asthma may lead to increased medication use, doctor visits and more hospital admissions. The gravity of these effects depend on the type of pollutant the person is exposed to, the degree of exposure and the individual’s health status and genetics.

A research done by the World Health Organization (WHO) states that the youngest, the oldest and the poorest are the most vulnerable urban populations to air pollution – it affects the central nervous system, playing a role in autism, as well as in other neurodevelopmental disorders. It also affects short-term memory, learning ability, impulsivity and the cognitive performance. Babies and children are particularly sensitive to the harmful effects of pollutants because they are growing and their lungs, cardiovascular system, immune system and brains are still developing.

When the AQI levels are high, the recommendation is to stay indoors and avoid doing physical activities outside, like jogging, hiking, cycling, etc., especially for sensitive groups like children, elderly and people with lung and heart conditions. If it’s inevitable to go outside, an air-pollution mask should be worn. Nevertheless, indoor pollution should be taken care of. Having a good air purifier and purifying plants at home or office are recommended, and to ensure the good air quality, avoid smoking indoors and make sure that there is a chimney in the kitchen and an exhaust in the bathroom.

A healthy diet rich in vitamin C, magnesium and Omega fatty acids might help to protect you from air pollution. You can also protect yourself and your family with Prana Air extensive range of anti-pollution solutions, like our motion mask and our air purifier. Find them here: Prana Air

Government agencies have different ways of measuring their respective Air Quality Index and use this information to inform the public of potential short-term health risk. Readings from government monitoring stations all over the world can be found here. For more precise information, you could consider installing a monitoring station at your home/office and use an app such as AQI India (COMING SOON).

Prana Air Indoor Air Purifier

You should change the filters ideally every 2 months.

The air purifier is meant to be runned for long hours. However, we recommend using it for a maximum 18 hours per day.

Yes, the Prana Air Purifier is designed to remove 99% of a wide range of pollutants – formaldehyde, PM10, PM2.5, dust, pollen, smoke odors, allergens, 0.3um particles, VOC, H1N1 virus, bacterias – in just 1 hour.

No, HEPA filters cannot be cleaned, only changed. If they are in touch with water, they get damaged.

No. Once changed, the HEPA filter cannot be used again. They are disposable once particles as small as 2.5 microns get attached to them.

Yes, that’s the reason behind the ionizator function

No, it won’t purify these gases.

Prana Air Purifier does not have an air pollution indicator on it.
