The short answer is no. However, air purifiers can be advantageous for improving air quality by increasing the amount of fresh air around an area and removing other pollutants that may contribute to the levels of CO2 and buildup.

Today, indoor air quality is prioritized due to the time humans spend in indoor spaces. Air purifiers are considered a savvy answer to indoor air pollution and pollutant contamination.

Nonetheless, the question emerges as to whether air purifiers can reduce carbon dioxide levels, which lead to lightheadedness and migraines and ultimately result in respiratory difficulties.

As indoor air quality experts, we will provide the necessary information to explain how air purifiers work and how indoor carbon dioxide levels can be reduced in indoor spaces.

We will also observe other effective ways to trap harmful carbon dioxide particles. By the end of this article, you will be able to make a rational decision on whether you should use an air purifier or not for your own space. Let’s get started!

The Mechanism of Air Purifiers

How air purifiers work

An air purifier removes harmful particles and contaminants to enhance the overall air quality of an area.

Air purifiers take in air from the surrounding environment and pass it through various filters.

These filters collect particles like smoke, dust, pollen, and other allergens. Some air purifiers contain ionizers or UV-C lamps that can eliminate bacteria and germs.

How air purifiers reduce carbon dioxide

To be exact, carbon dioxide is not a particulate substance but a gas that cannot be removed by air purifiers or basic mechanical ventilation alone.

Nevertheless, activated carbon filters that can sometimes be inside air purifiers can eliminate odors and volatile organic compounds (VOCs), thus boosting indoor air quality.

Types of air purifiers

Various air purifiers include HEPA filter (high-efficiency Particulate Air) filters, activated carbon filters, ionizers, ozone generators, UV-C lamps, and hybrid air purifiers that combine two or more technologies.

Each type has advantages and drawbacks, and the appropriate purifier type depends on the indoor air quality requirements.

Health Benefits of Air Purifiers

Improves air quality for respiratory issues

Air purifiers are devices designed to enhance air quality within the home. People with respiratory illnesses like asthma or allergies can benefit significantly from this device.

Air purifiers clear the air of harmful components, such as dust, pet dander, and pollen, which can aggravate symptoms of difficulty breathing.

Reduces carbon dioxide effects on human health

Air purifiers can help improve one’s overall health and also decrease carbon dioxide’s impact on the human body. When concentrations of this gas are too high, it can result in headaches, dizziness, slight nausea, and exhaustion.

The Role of Carbon Dioxide in Climate Change

How carbon dioxide contributes to global warming

Carbon dioxide contributes to global warming by trapping warmth and energy elsewhere in the ecosystem.

environmental protection, natural reserve, ecology

The Earth’s surface absorbs sunlight and radiates the power again into the surroundings. However, carbon dioxide and different greenhouse gases prevent this energy from escaping, creating a greenhouse impact that causes the Earth’s temperature to rise—global warming results in rising sea degrees, melting glaciers, and more common and intense weather events.

Carbon dioxide sources

There are many sources of carbon dioxide, such as fossil fuels and natural gas combustion from transportation and industry, deforestation, and agricultural practices.

People are releasing more carbon dioxide than ever before, making global warming worse by increasing the levels of these greenhouse gases in the environment.

Carbon footprint reduction

Reducing one’s carbon footprint can assist in mitigating the influence of indoor carbon dioxide concentrations and other gases in the surroundings.

Ways to minimize the carbon monoxide footprint include public transportation or electric-powered vehicles instead of driving, decreasing meat consumption, and utilizing renewable power resources consisting of solar and wind electricity.
