How do I know if air at home is good?



How do we know about the air we breathe is clean and healthy?

To some extent, we rely on our own minds. For example, we sometimes see large particulate pollutants in the air with the naked eye when the sun shines through the windows. Polluted air often feels trapped because the nose is fantastic to register multiple contaminants at very low levels. Some of these pollutants are filtered out in the nose and upper respiratory passages, but this is far from all pollution; the rest goes into the lungs. Some particles are so small that they pass the lung tissue and are absorbed directly by the blood.

 Asthma and poor air quality in homes

People with asthma can have their symptoms worsened sharply in connection with the stay in buildings with poor air quality. Many of the symptoms can be naturally also caused by other than the bad air, but studies show that symptoms occur more often in buildings with poor air quality.

Did you know that…

 Warm air is often perceived as stuffy and poor!

 CO2 in homes!

Many hazardous substances in our homes and in indoor air are neither smell nor give any clear symptoms. Clearly, however, that good ventilation is a very important prerequisite for the indoor air to be and be perceived as clean and healthy.

With simple measuring devices for household use, we can measure the air temperature and humidity. But to answer the question about the air we breathe is clean and healthy we need other instruments.

Carbon dioxide (CO2) in homes to measure air quality

The concentration of carbon dioxide (CO2) is often used as a simple measure of air quality. Carbon dioxide meter is relatively simple and inexpensive. Carbon dioxide is measured as parts per million by volume of air. One thousand parts per million of CO2 in the air volume (1 000 ppm) is a frequent limit for acceptable long-term carbon dioxide level.
