Breathe Easy: The Importance of Indoor Air Disinfection Technology
This post was written by: Ashley Medina Tallyn, MHA, RRT.
Indoor air quality is important to maintaining healthy lungs, especially for those living with chronic respiratory conditions like COPD. There are many air disinfection technologies available. Each one uses a different method to improve indoor air quality. Understanding the available options can help you make an informed decision about the best way to clean the air in your home or workplace.
The air inside buildings or homes can trap dust, mold spores, allergens, bacteria and viruses. Breathing in these particles can negatively impact your lung health and create serious health risks. While air filtration can capture some of these particles, air disinfection technologies go a step further by cancelling out potentially harmful pathogens.
Types of Indoor Air Disinfection Technologies
-
Mechanical Filtration (like HEPA Filters)
HEPA (High-efficiency Particulate Air) filters use a fine mesh to trap particles, such as dust and allergens. Some filters can even catch large bacteria and virus particles, although the smallest pathogens may pass through a HEPA filter. However, these filters do not kill germs, so live pathogens sit on the filter if it is not changed often.
-
UV-C Light Disinfection
UV-C light breaks down the DNA or RNA of germs so they can't spread. This method can sanitize the air as it passes through the system. The effectiveness relies on directly exposing the germs to the light, and it takes time to work. Also, the bulbs in UV-C products lose potency over time and will need replacement.
- Ionizers and Electrostatic Filters
These devices release charged ions that attach to particles in the air, making them heavy so they fall to the ground or get caught on electrostatic plates. Ionizers can help clear the air, but may create ozone as a byproduct, which can irritate the lungs.
- Plasma-based Technologies
Plasma-based systems use electrical energy to create particles that can inactivate germs in the air. Some portable air purifiers use plasma-based technology to quickly neutralize airborne pathogens without producing harmful byproducts.
Medical-grade and FDA-cleared Products
Some air disinfection products are labeled as medical-grade and are FDA cleared. This means they have been tested to make sure they work well and are safe to use. These products are often used in sensitive environments, making them a great option for people with chronic lung conditions.
Choosing the Right Air Disinfection Technology
To pick the best air disinfection system, think about your needs and where you will use the device. Some things to consider:
- Compare options: Learn how each type of technology works and what benefits it offers.
- Look for certifications: Products tested for safety will have FDA clearance or other certifications like UL ratings or CARB certification (California Air Resource Board).
- Match your space: Choose a product that fits the size of the room and meets the needs of those using the space.
- Factor in ongoing costs: Consider if the product requires ongoing purchases like filters, bulbs or other items to maintain its effectiveness.
- Assess environmental impact: Check if the product has components that require safe disposal and if handling them requires protective equipment, such as gloves, masks or face shields.
Air disinfection technology helps keep indoor air cleaner and healthier. Choosing the right technology depends on your needs, the size of your space and your health priorities. Companies like Clean Air Dynamics offer a range of solutions to help clean indoor air.
By exploring the different options of air disinfection technologies and selecting high-quality products, you can create a safer environment for yourself and those around you.
