Breathe Cleaner, Healthier Air with Whole-Home Filtration

Whole-home air filtration systems are a critical component of your HVAC system’s performance and your home’s overall air quality. Despite their importance, they are often overlooked in routine maintenance and HVAC design.

Filtration is one of the most effective ways to remove airborne contaminants as air circulates through your HVAC ductwork. A high-performance air filter or filtration system captures and removes particulate matter such as dust, pollen, pet dander, smoke, and other allergens—improving both comfort and respiratory health.

At Bay Air Heating & Cooling, we help homeowners throughout Marin County and San Francisco select and install the right filtration solution for their specific needs.

Why Indoor Air Quality Matters- And How You Can Take Control

Indoor air quality (IAQ) plays a direct role in your health and comfort. Pollutants like dust mites, pollen, mold spores, smoke, and volatile organic compounds (VOCs) can exacerbate allergies, asthma, and other respiratory conditions. VOCs are found in everyday products such as cleaning agents, furniture, and flooring materials. Today’s homes are built to be airtight and energy-efficient, which means that airborne pollutants become trapped indoors. According to the EPA, indoor air can be two to five times more polluted than outdoor air.

You can improve your home’s air quality through three core strategies:

Source control: Eliminate or reduce sources of indoor pollutants.
Ventilation: Introduce fresh air into your living space through mechanical or natural means.
Filtration: Use high-efficiency filters to capture fine particulate matter.

Bay Air offers a range of high-performance air filtration systems designed to meet your home’s unique needs. When it comes to protecting your indoor air, trust the HVAC professionals at Bay Air Heating & Cooling. Our certified technicians will assess your air quality, recommend the best solution, and ensure proper installation and system compatibility.

Choosing the Right Air Filtration System for Your Home

Whole-home air filtration systems integrate directly with your existing HVAC equipment to continuously purify air as it circulates through the ductwork. The right system can reduce allergy symptoms, control odors, and even help manage asthma triggers.

Here’s a breakdown of the most effective air filtration technologies:

HEPA Filters (High-Efficiency Particulate Air)

Captures 99.97% to 99.99% of particles ≥ 0.3 microns, including pollen, bacteria, dust, and mold. Often combined with activated carbon to absorb smoke, chemicals, and odors. Typically rated MERV 17–21. Note: HEPA filters may require modifications to your HVAC system due to their density and potential to restrict airflow. Our technicians will ensure compatibility.

Media Air Cleaners

4–5 times thicker than standard filters, allowing a larger surface area for filtration. Effectively trap up to 95% of airborne particles. Longer lifespan—usually replaced every 3–6 months. Low maintenance and excellent for general household air quality improvement.

Electrostatic Filters

Use static electricity to attract and trap airborne particles. Washable and reusable; up to 97% efficient at removing fine particulates. 30x more effective than traditional fiberglass filters. Ideal for homes with high dust levels or allergy sufferers.

Electronic Air Cleaners (EACs)

Use high-voltage current to ionize particles and capture them on a collector plate. Capable of removing up to 99.9% of pollutants, including smoke, bacteria, VOCs, and even ozone. Some models integrate UV-C light for added germicidal protection. Not sure which solution is best for your system or budget?
