Common Misconceptions About HVAC Filtration
One of the most persistent myths in home comfort systems revolves around air filters and their ratings. At Bayside Mechanical, we frequently encounter customers who believe that higher-rated MERV filters are always better for their HVAC systems. This simply isn’t true, and here’s why.
Understanding the MERV Rating System
MERV (Minimum Efficiency Reporting Value) ratings range from 1-20, with higher numbers indicating finer filtration. However, installing the highest-rated filter isn’t always the best choice for your system. Here’s what you need to know:
• Higher MERV ratings mean smaller pore sizes
• Restricted airflow can strain your system
• Not all HVAC systems are designed for high MERV filters
The Real Impact on Your System
Using a filter with too high a MERV rating can:
– Reduce system efficiency
– Increase energy costs
– Potentially damage your HVAC system
– Lead to insufficient heating and cooling
Finding the Right Balance
For most residential systems, a MERV rating between 8-11 provides excellent filtration while maintaining proper airflow. This range effectively captures:
– Dust and pollen
– Most airborne particles
– Common allergens
– Mold spores
Professional Guidance Matters
The best filter choice depends on your specific system, home environment, and family’s needs. Having your system evaluated by a professional ensures you’re making the right choice for your HVAC equipment’s longevity and your indoor air quality.
