Improve Indoor Air Quality in Los Angeles Homes

January 14, 2026
indoor air quality

Spring's arrival brings with it a sense of renewal, as the world awakens from winter's slumber. However, for many, this season also ushers in a wave of allergies and respiratory discomfort. While we often associate air quality concerns with outdoor pollutants, indoor air quality (IAQ) can be significantly worse. This spring, take proactive steps to transform your home into a sanctuary of clean, healthy air. Your HVAC system plays a crucial role in this transformation, and understanding how to optimize its function is essential for a comfortable and healthy living environment.

The Hidden Dangers: Understanding Indoor Air Pollutants

Indoor air pollutants are diverse and can originate from various sources. Common culprits include dust mites, pet dander, mold spores, pollen, volatile organic compounds (VOCs) released from household products, and even combustion byproducts from cooking or heating. These pollutants can trigger allergies, asthma, and other respiratory issues, impacting your overall well-being.

Spring's increased pollen counts exacerbate existing allergy symptoms, while the lingering moisture from winter can contribute to mold growth. Dust mites, thriving in warm, humid environments, become more active during this season. Understanding these pollutants is the first step towards creating a healthier indoor environment.

Your HVAC System: A Powerful Ally in the Fight Against Allergens

Your HVAC system is more than just a temperature regulator; it's a critical component in maintaining healthy indoor air quality. By optimizing its function, you can significantly reduce the presence of allergens and pollutants in your home.

1. High-Efficiency Filters: Trap More Dust and Allergens

Your HVAC air filter is the first step to cleaner air.
Upgrading to a high-efficiency filter with a MERV rating of 11 or higher helps catch more tiny particles like:

  • Pollen
  • Pet hair and dander
  • Mold spores
  • Dust mites

These filters clean your air better than regular ones.

2. Humidity Control: Keep Mold and Dust Mites Away

Too much moisture in your home can lead to mold and dust mites—both bad for your health.

Your HVAC system can help control humidity.
For extra help, consider adding a dehumidifier to keep your home’s humidity between 30% and 50%.
This makes it harder for mold and dust mites to grow.

3. Proper Ventilation: Bring in Fresh Air

Good airflow is important for clean indoor air.

When your HVAC system is working right, it moves filtered air around your whole house.
If your home is tightly sealed, you might want to install a whole-house ventilation system to bring in more fresh air from outside.

4. Regular Maintenance: Keep Your System Working Right

Your HVAC system needs checkups, just like a car.

A trained technician can:

  • Clean important parts
  • Check refrigerant levels
  • Catch small problems before they get worse
  • Clean coils that collect dust, mold, and dirt

Regular maintenance helps your system work better and keeps your air cleaner.

5. Air Scrubber by Aerus: Clean Air All Day Long

For next-level air cleaning, consider the Air Scrubber by Aerus.

It uses ActivePure® Technology to remove:

  • Dust and pollen
  • Pet dander and mold
  • Germs, viruses, and bacteria
  • Smells and chemicals (VOCs)

Unlike filters that wait for air to pass through, the Air Scrubber actively sends out particles that find and destroy pollutants in the air and on surfaces.

It’s great for:

  • People with allergies or asthma
  • Improving your home’s air quality
  • Creating a healthier place to live

Beyond HVAC: Additional Strategies for Improved IAQ

While your HVAC system plays a vital role, other strategies can further enhance your indoor air quality:

Regular Cleaning: Dusting, vacuuming, and mopping regularly can remove accumulated allergens and pollutants.
Pet Grooming: Regularly grooming pets can reduce pet dander in the air.
Avoiding VOCs: Choose low-VOC or VOC-free cleaning products, paints, and furniture.
Proper Ventilation During Cooking: Use range hoods and open windows when cooking to remove combustion byproducts.
Controlling Mold Growth: Address moisture problems promptly to prevent mold growth.
Using Air Purifiers: Consider using portable air purifiers in bedrooms or other high-traffic areas.
Creating a Healthy Home Environment: A Proactive Approach

Improving indoor air quality is a proactive approach to maintaining a healthy and comfortable living environment. By understanding the sources of indoor pollutants and optimizing your HVAC system, you can significantly reduce the presence of allergens and irritants in your home.

This spring, take control of your indoor air quality and breathe easier. Don't let allergies and respiratory discomfort dictate your comfort. By implementing the strategies outlined above, you can create a sanctuary of clean, fresh air for you and your family.
