HEPA filters are widely recognized for their ability to improve indoor air quality by trapping allergens and pollutants.

Q: What are HEPA filters?

A: HEPA stands for High-Efficiency Particulate Air. These filters are designed to trap particles as small as 0.3 microns with an efficiency rate of 99.97%.

Q: How do HEPA filters work?

A: HEPA filters capture airborne particles using a combination of diffusion, interception, and inertial impaction. As air passes through the filter, particles collide with fibers and are trapped.

Q: What types of allergens and pollutants can HEPA filters trap?

• Pollen
• Dust mites
• Mold spores
• Pet dander
• Smoke particles
• Bacteria
• Viruses

Air Quality Improvement Statistics

Studies show that HEPA filters can reduce indoor airborne allergens by up to 90% in rooms where they are used. The effectiveness can vary based on the size of the space and actual air circulation.

Key Considerations for HEPA Filters

• **Room Size:** HEPA filters are most effective in smaller, contained spaces.
• **Airflow:** Proper airflow is crucial for maximum efficiency.
• **Filter Maintenance:** Regular maintenance ensures continued effectiveness.
