How daily activities affect indoor air

Reasons to care about indoor air quality

You should care about indoor air quality because your health is heavily dependent on it. If you are breathing poor air, it can cause health issues ranging from headaches, asthma, birth defects, cancer, heart and respiratory diseases and even death.

People in urban areas spend most of their time indoors. Indoor air can carry thousands of pollutants due to everyday activities or the usage of electrical appliances.

Besides that, when people try to make their homes more energy efficient, they are also creating tightly closed spaces, so sealed that fumes such as volatile organic compounds (VOCs) can build up. These can be found in biological irritants (dust mites and mould) and in many household products.

Now that we know why it is important to be aware of our indoor air quality, let’s have a look at its causes.

Everyday Activities That Cause Air Pollution

It has been established that human activities contribute largely to environmental adversity through everyday activities. There are such activities that release ozone-depleting substances and greenhouse gasses, so recognising and isolating such activities or habits is imperative to remedy the consequences and, more importantly, to avoid any further contributions.

Everyday human activities

While most of us relate air pollution to images of the exhaust of cars in big cities and large industrial facilities, few are aware that there are daily activities that contribute to the problem too.

Such activities not only pollute the outside air but the indoor air too. In fact, according to the Environmental Protection Agency (EPA) in U.S.A., the air indoors is five times more polluted than the air outside.

The following is a list of such activities:

The use of kitchen stoves

Although is difficult to avoid, at least you should be aware of it. The kitchen stoves that work with gas release nitrogen dioxide which is a highly reactive gas. This gas reacts with the oxygen and moisture in the air forming toxic nitrates and nitric acid.

Packaged spray products

Products such as air fresheners, cleaners and body deodorants release harmful air polluting particulates such as volatile organic compounds which are also known to cause certain long-term health effects. Also, most of the home paints come with toxic pollutants that release air borne particulates.

Air conditioners and refrigerators

Almost every household makes use of these appliances which in turn use ozone-depleting aerosol sprays to condition and modulate room temperature or to keep our food fresh and edible.

Our litter

All the garbage that comes out of our houses is dumped in massive areas and generate methane, another toxic gas.


Indoor air quality is a complex interaction of different factors. These factors include various sources of pollutants or odours. To control air quality there are three main approaches: first, you can control the timing of the appliances that generate them; second, you can help remove them through ventilation; and third, use filtration systems to clean the air of pollutants.

Purlife’s indoor air purifier can remove up to 99.97% of pollutants thanks to its 3M™ HEPA filter and it even has a smart sensor and auto speed mode function to work according on air quality. So, it’s a very effective solution to improve the quality of the air you breathe at home.
