Indoor Air Quality (IAQ) Essentials
Changing your HVAC air filters regularly is one of the simplest ways to maintain clean indoor air. Filters capture dust, pollen, and other particles that affect comfort and health. When filters are clogged, they lose efficiency and can strain your HVAC system, leading to higher energy use and reduced performance.
Additional Filtration Options
HEPA Filters
Captures particles as small as 0.3 microns (great for allergens) but may restrict airflow in most HVAC systems. They usually need replacement or cleaning every 6 months, depending on usage and indoor conditions.

Reduce odors, gases, and VOCs. They typically need replacement about every 6 months, depending on the brand, system run time, and indoor air quality conditions.
Learn more →Electronic Air Cleaners
Effective against fine particles, but some models may produce ozone if not maintained properly. The collector cells should be cleaned about every 6 months.
Learn more →Understanding Static Pressure
Think of static pressure as the resistance your HVAC system faces when pushing air through its ductwork and equipment. It's like pushing air through a straw. When the straw is wide, air moves easily with little resistance. When the straw is narrow, it takes more effort because of the increased resistance. In the same way, your HVAC system experiences resistance as it moves air, which affects its efficiency and performance.
MERV Ratings & Filter Thickness Breakdown
| Filter Thickness | MERV Rating | Particle Size Captured | Effect on HVAC System Strain | Typical Use Case |
|---|---|---|---|---|
| 1" (Standard) | 4–6 | Over 10.0 microns | Low to Moderate | Basic filtration for dust, lint, pollen |
| 1" (Standard) | 8–11 | 3.0 – 10.0 microns | Moderate to High | Captures dust, pollen, and pet dander |
| 1" (Standard) | 12–13 | 1.0 – 3.0 microns | High | Allergy relief captures smaller particles but may restrict airflow |
| 2" | 8–11 | 3.0 – 10.0 microns | Moderate | Better airflow, good for dust, pollen, and pet dander |
| 2" | 12–13 | 1.0 – 3.0 microns | Moderate | Good airflow and filtration against allergies, dust, pollen, and pet dander |
| 4" – 5" | 8–11 | 3.0 – 10.0 microns | Low | Improved airflow but not effective at filtering allergens |
| 4" – 5" | 12–16 | 0.3 – 1.0 microns | Low to Moderate | Best filtration. Used in hospitals, large commercial buildings, and residential systems with well-designed ductwork and HVAC equipment that can support higher airflow. |
Key Considerations
System Compatibility
Make sure your system can handle the chosen filter size and MERV rating.
Health Needs
Higher MERV filters help with allergies but may restrict airflow if not matched correctly.
Regular Maintenance
Replace filters on schedule to protect both indoor air and system performance.
Ways to Improve Air Quality
Air Purifiers & UV Lights
UV light helps neutralize bacteria, viruses, and mold spores in the air.
Learn More →Ductwork & Humidity
Well-maintained ductwork and proper humidity control help prevent mold, dust mites, and poor airflow.
