When considering safety at home, people usually overlook the role played by air quality. Because the air is colorless and seems quite harmful, you may hardly see how low air quality contributes to significant death rates yearly. Toxins, dangerous chemicals, and gases can become leaked in one’s home, leading to severe complications in the long run. Ultimately, it is essential to know how to monitor air quality at home. With all the methods to check indoor air quality, using air quality monitors is an effective way to tackle the problem. Usually, you could hire a professional or walk down to the store to get an air quality monitor like this one on Amazon.

However, we have saved you the stress by compiling the measures to address low indoor air quality and some of the best monitors.

Reasons Why You Should Monitor Air Quality At Home

 How To Monitor Air Quality At Home Easily & Be Happy

Polluted air can pose a dangerous threat to our health, and so, monitoring air quality should be a significant part of our routines.

Besides, toxins can seep through small cracks and various openings that we can’t identify with our bare eyes.

Many people don’t feel threatened by possible air quality issues because they haven’t suffered any unusual symptoms. However, it is smart to know how to monitor air quality at home. And some of these situations include the following:

  • You can’t point out a definite cause for sudden allergic symptoms you’re facing
  • You suspect mold in your home
  • The house feels very stuffy, probably with slight unusual odors
  • You intend to run a general safety check at home.

Measures For Checking Indoor Air Quality

Air quality is measured in AQI- the Air Quality Index. Quality Indoor air is measured by many factors, of which it is crucial to check the following:

  • Adequate ventilation. Having a well-ventilated apartment means there’s enough airflow coming in and a corresponding volume of air exiting the building. If one or both of these processes fail, you will have an issue with your indoor air quality.
  • Controlled contaminants. Contaminants can quickly enter a building through openings that allow harmful gases like Volatile organic compounds (VOCs) and Carbon monoxide (CO) into the house. At low levels of these gases, your indoor air is much better for breathing. 
  • Good temperature and humidity levels. The Temperature/humidity level indoors should also be comfortable. If you feel uncomfortable with how dense the atmosphere feels, you need to check its quality.

How To Monitor Air Quality At Home

If you’re planning to run an indoor air quality check, below are some ways you could go about it:

  • Using an air quality monitor

Yes, some devices monitor how good your atmosphere is. Most people are not conversant with the use or even the existence of IAQ monitors.

An indoor air quality monitor is an electronic device that stays on 24/7 to check and report atmospheric pollution levels within a building.

IAQ monitors’ operation varies from device to device, although their basic functions are to check chemical pollutants, particulate matter, and humidity. Other specialized models will even check carbon monoxide and carbon dioxide levels, temperature, and formaldehyde amounts.

  • Mold Testing

Mold grows indoors, sometimes, probably on spoilt food or old clothes stored up in a closed bin for months.

But, how about the mold we can’t see- the ones flying around in the air? If you’ve got some at home, you probably breathe the spores daily!

However, if you find yourself having unaccounted for allergies and other symptoms, your home might be stuffy with mold in the air. If so, seek professional advice to get rid of them.

  • Radon test.

Like Carbon monoxide, radon has no taste, color, or physically detectable qualities- and it is dangerous in specific amounts.

Radon can pass through cracks or pipes into your house, and since it is sourced from the disintegration of uranium in soil, it collects at the base of your home and accumulates.

Radon tests range from simple to critical processes. You may also have to consult a professional to handle the condition as it may be.
