Indoor air: what’s inside?


Are you breathing good quality air?

Breathing good quality air is a growing concern among people, especially at the moment. When outside, we often get worried about pollution caused for example by cars or factories. Is our indoor air at home any better? Probably not: indoor air can be up to 5 times more polluted than outdoor.

As we are all spending more time in our homes, here’s a list of the most common pollutants to look out for.

Biological contaminants

The quality of air inside your home can be affected by many different factors such as temperature, humidity levels, ventilation, chemicals, and small particles.

Biological contaminants are the most common pollutants. Some examples are mold and bacteria. They all come from a living source and spread around the house especially where there are conditions such as high humidity, damp or wet areas. Keeping the humidity levels between 30 and 50 percent can be useful to reduce the risk of pollution from these contaminants. 

Carbon monoxide

Carbon Monoxide is a colorless and odorless gas that can be difficult to detect without a proper device. The most common sources of this pollutant include appliances such as gas stoves, water heaters, power tools such as gas-powered tools, and smoke coming from cigarettes or fireplaces. The effects on health vary depending on the CO levels inside the house and become dangerous only when reaching high peaks. Remember to have your heating system inspected regularly in order to keep CO levels under control. 


Formaldehyde is a colorless gas produced as a result of combustion that can also be found in tobacco smoke or in the emissions produced by fuel-burning heating systems. It can also be released by furniture made from particleboard or compressed wood when exposed to hot conditions. To reduce the presence of these contaminants in your home, don’t forget to keep the environment ventilated and try to buy furniture made with safe materials. 

Volatile Organic Compounds

A volatile organic compound or VOC is a gas that gets released into the air by some type of products. Levels of VOCs can be up to 10 times higher inside than outside. Some of the elements that can produce VOCs in your home are paint, cleaning products, carpeting, laminate flooring, air fresheners, pesticides, glue, dry cleaning solutions, permanent markers, and cosmetics. Good ventilation together with opening the windows often can help lower the exposure to these pollutants. 

If you want to make your home environment healthier and safer, you can go for an air purifier device that not only will help to keep a good air quality but will also monitor the levels of contaminants. H-PURIFIER can be connected to the hOn App that will collect data on both inside and outside air quality giving you real-time information about pollution and humidity levels to help you live and breathe better.
