The CO2 Question: Can Air Purifiers Remove It?
Indoor air quality directly affects productivity and overall health and well-being. Most people spend the majority of their time indoors, making it important to understand how air purifiers affect pollutants like CO2. One frequent question is: Do air purifiers remove CO2?
No. Household air purifiers cannot remove carbon dioxide. CO2 is a gas with a molecular weight of 44 g/mol. Carbon dioxide is a natural component of the atmosphere and is part of the carbon cycle, which regulates CO2 levels on Earth and helps maintain climate stability. Standard air purifiers focus on filtering particulate matter, not gases.
It's important to note that the main carbon dioxide sources in indoor environments include exhalation from occupants and combustion processes, both of which contribute to indoor CO2 levels and can impact health and air quality. To better understand what air purifiers can accomplish, it’s useful to learn about filtration methods and how they impact indoor environments.
Understanding CO2 Indoors
Carbon dioxide occurs naturally in the atmosphere. Humans and animals exhale it, while plants absorb it. High CO2 levels indoors often result from combustion appliances, gas stoves, or burning candles. Combustion processes, including the use of natural gas, are significant contributors to indoor CO2. Poor ventilation allows CO2 to accumulate, which can cause fatigue, dizziness, and reduced concentration.
Is Carbon Dioxide (CO2) Toxic?
Carbon dioxide becomes harmful when concentrations rise beyond safe limits. While CO2 itself is not classified as a poison, elevated levels displace oxygen in the air and restrict the body's ability to function efficiently. Breathing clean air with low CO2 levels is essential for long-term health.
What Level of CO2 Is Toxic to Humans?
CO2 interferes with oxygen delivery to tissues. When inhaled in high concentrations, it prevents the body from receiving enough oxygen. This results in increased respiratory rate, impaired brain function, and even cardiovascular stress. Poorly ventilated spaces contribute to this imbalance and raise the likelihood of symptoms.
CO2 concentrations above 1,000 parts per million (ppm) can lead to discomfort and reduced performance. Levels above 5,000 ppm pose serious health risks and should be avoided. Indoor spaces should maintain CO2 levels below 800 ppm to ensure optimal comfort and well-being.
What Are the Symptoms of Carbon Dioxide Poisoning?
People exposed to high indoor CO2 levels may feel tired, confused, or dizzy. Other symptoms include shortness of breath, headache, and reduced concentration. In more severe cases, especially when ventilation is lacking, individuals may experience rapid breathing or even unconsciousness.
Why Most Air Purifiers Cannot Remove CO2
The term “air purifier” often implies full air cleaning, but that’s not accurate when it comes to gases. Most air purifiers use HEPA filters, which work well for removing particulate matter like allergens or dust. However, they do not trap carbon dioxide.
HEPA filters capture 99.97 percent of particles as small as 0.3 microns. They can remove pollen, smoke particles, and pet dander. Since carbon dioxide exists as a molecular gas, it passes through these filters.
Some air purifiers include activated carbon filters. These help absorb certain gases and odors. Activated carbon has a porous structure that binds with specific chemicals. While these filters can reduce contaminants for improved indoor quality, they cannot remove carbon dioxide.
Air Filters & Indoor Air Quality
Air filters are essential for maintaining healthy indoor air quality by capturing particulate matter, volatile organic compounds, and other indoor pollutants. Most air purifiers with HEPA and activated carbon filters effectively trap dust, pollen, pet dander, and some toxic gases and odors. However, they cannot remove carbon dioxide (CO2).
Elevated indoor CO2 often results from poor ventilation, combustion appliances like gas stoves, burning candles, or smoking. High CO2 levels can cause impaired cognitive function, reduced productivity, and discomfort.
To reduce CO2 and improve indoor air quality, mechanical ventilation such as HVAC systems, exhaust fans, or opening windows is necessary. Adding plants like snake or spider plants can help absorb some CO2, but they are insufficient alone, especially in poorly ventilated or crowded spaces.
Air purifiers are effective for many other indoor air pollutants, but not for CO2. Managing CO2 requires proper ventilation and airflow to create a healthier indoor environment and support overall well-being.
Tips to Manage CO2 Indoors
Air purifiers can play a role in cleaner air, but CO2 control involves additional steps. Proper ventilation and the introduction of outdoor air are crucial for maintaining a clean indoor environment and promoting a healthy indoor space.
How Do I Remove Carbon Dioxide from My Home?
Open windows regularly and use HVAC systems or exhaust fans to increase ventilation with outdoor air. When ventilating, especially in urban areas, consider outdoor air pollution and use air purifiers to help mitigate its impact. Introduce indoor plants like spider plants or snake plants to improve oxygen levels. Reduce the use of combustion appliances such as gas stoves and candles. Monitor air quality with a CO2 monitor. Choose purifiers like Airdog that improve air flow and reduce airborne pollutants.
Do Plants Remove Carbon Dioxide?
Plants absorb carbon dioxide during photosynthesis. Indoor greenery helps reduce CO2 levels while increasing oxygen production. Common indoor plants like spider plants, pothos, and snake plants are known for their air-purifying properties. These plants offer a natural way to lower CO2 and create a fresher indoor atmosphere.
How Airdog Improves Indoor Air Quality
Airdog focuses on improving indoor air beyond what traditional HEPA air purifiers achieve.
Airdog uses patented Two-Pole Active (TPA) Technology. This method goes beyond trapping particles. It actively neutralizes harmful pollutants. TPA filters eliminate particles as small as 0.0146 microns. That includes viruses, fine particulates, and bacteria. The filters are washable and reusable, reducing waste and cost.
Airdog enhances overall air conditions in several ways. It supports steady airflow and reduces buildup of pollutants that intensify CO2-related symptoms. It also integrates activated carbon components that reduce odors and some gases. Airdog complements your strategies to manage CO2 like ventilation systems and indoor plants for the best possible indoor air quality. These combined approaches contribute to a healthier environment..
CO2 and Indoor Air Strategy
Air purifiers alone do not remove carbon dioxide effectively. Still, they remain an essential part of managing indoor environments. Airdog’s TPA technology eliminates dangerous particles and promotes cleaner air overall. Combine this with good ventilation, indoor plants, and smart appliance use for the best results.
Why Airdog Offers a Smarter Air Purifier Solution
Improving air quality means more than filtering particles. Airdog delivers energy efficiency, reduces waste, and captures ultra-fine particles that standard HEPA filters miss. Washable filters prevent waste buildup and maintain strong performance over time. HEPA filters clog easily, while Airdog maintains consistent effectiveness with TPA filtering.
