Dust mites live in bedding, mattresses, carpets, and curtains. Although you can reduce the presence of mites through cleaning, air quality has a lot to do with keeping mites away from your home.

Mites are responsible for asthma and other symptoms such as coughing and wheezing. Pollen is common through spring and summer. It comes into the house through windows and another opening.It can make people sneeze, cough, and it can create itching eyes, nose and throat, and red watering eyes.

Best ways to check air quality in your house

You can check the air quality in your house in various ways. Unfortunately, there isn’t one test or tool that can tell you in one go what is wrong with your air, but there is a series of examinations and things you can do with all the data you need.

Here are the things you can do to check air quality:

1.   Install an indoor air quality monitor

An indoor air quality monitor is an electric device that aims to measure the level of pollution in the air. Each brand can test different things, but you can expect an air quality monitor to determine the level of chemicals, particulate matter, carbon dioxide, formaldehyde, and humidity.

You can find intelligent devices with a display monitor that shows the readings in real-time. Moreover, you can connect those devices with your home thermostat, mobile phone, and other devices.

2.    Mold testing

You can also make a separate mold test to ensure your house is free of the harmful effects of mold and its byproducts. Mold tests can be various, such as:

  • Swabs
  • Tape strip
  • Air pumps
  • Petri dish test

Some of the above tests require you to send the sample to a laboratory, and it will take a few days to know the results. You can also inspect your home to check for visible signs of mold. The places to examine are those where there is the most humidity.

For example, basements, dirty ductwork, drains are the usual place where mold can proliferate. In addition, you can also see if there are black spots on walls or other surfaces.

3.     Carbon monoxide alarm

You can also use carbon monoxide detectors to alert you if the gas levels go beyond a specific threshold. The presence of alarm monitors is necessary because the gas is odorless, and you cannot detect its existence from the color or any other sign.
