What Are Air Filters and How Do They Work?
Air filters are devices designed to remove contaminants from the air inside your home. Installed in your HVAC (heating, ventilation, and air conditioning) system, they trap harmful particles, ensuring that the air circulating in your home is clean and safe to breathe.
How Air Filters Work
Air filters are placed in the path of the air flowing through your HVAC system. As air passes through the filter, harmful particles like dust, allergens, and bacteria are trapped, allowing only clean air to circulate in your home.
Different filters work in unique ways:
- HEPA filters capture tiny particles like mold, pollen, and bacteria, making them ideal for households with allergies.
- Activated carbon filters use a special layer to neutralize odors and remove harmful chemicals from the air.
- Fiberglass filters are affordable options that block larger particles, such as dust and lint.
- Electrostatic filters use static electricity to attract and trap particles for enhanced filtration.
By filtering these particles, air filters not only improve air quality but also protect your HVAC system from dirt buildup, ensuring it runs efficiently.
