When it comes to creating a healthier, cleaner home in Orange County, air filtration systems play a major role. With pollutants like dust, allergens, mold spores, and even outdoor smog infiltrating your indoor air, investing in the right filtration system can make a significant difference in your comfort and well-being.

At 20th Century Air, we understand that choosing the best air filtration solution for your space can be overwhelming. That's why we’re breaking down the most common types to help you determine which system fits your needs best.

1. Mechanical Air Filters (HEPA Filters)

High-efficiency particulate air (HEPA) filters are among the most popular options. These filters are designed to trap 99.97% of airborne particles as small as 0.3 microns. That includes dust, pet dander, pollen, and even some bacteria. They’re a great choice for allergy sufferers or households with pets.

Best for: Homes with allergy or asthma concerns, and those wanting superior filtration for particles.

2. Electrostatic Filters

These filters use an electric charge to attract and trap particles. Electrostatic filters are reusable and washable, making them a more sustainable option. However, they may not be as effective as HEPA filters when it comes to capturing smaller particles.

Best for: Budget-conscious homeowners looking for a reusable, mid-efficiency solution.

3. Activated Carbon Filters

Activated carbon filters specialize in removing odors, gases, and volatile organic compounds (VOCs) from the air. They don’t capture dust or allergens well, but they’re excellent for homes exposed to smoke, pet smells, or strong cooking odors.

Best for: Eliminating odors and chemical fumes in kitchens, garages, or smoking areas.

4. UV Light Purifiers

Ultraviolet (UV) air purifiers use UV-C light to kill bacteria, viruses, and mold spores. While they don’t trap particles, they’re often used in combination with other filtration systems to neutralize pathogens and boost air cleanliness.

Best for: Homes concerned with germs or in need of a more hygienic indoor environment.

5. Whole-Home Air Purifiers

These systems are integrated directly into your HVAC unit to clean the air throughout your entire home. Many combine multiple technologies, including HEPA, UV, and carbon filtration, for maximum coverage and efficiency.

Best for: Homeowners looking for all-in-one air purification tied to their existing HVAC system.
