The Impact of MERV Ratings on Indoor Air Quality
When it comes to maintaining your home’s HVAC system, one of the most crucial elements is choosing the right air filter. At Gordon’s Heating & Air, we often find that homeowners in Eden and Pooler, GA, are unsure about which filter best suits their needs.
MERV (Minimum Efficiency Reporting Value) ratings range from 1 to 20, with higher numbers indicating better filtration. Here’s what you need to know:
MERV Rating Breakdown:
- MERV 1-4: Basic filtration for large particles
- MERV 5-8: Good for residential use
- MERV 9-12: Excellent for homes with pets or allergies
- MERV 13-16: Hospital-grade filtration
- MERV 17-20: Clean room and surgical environments
For most homes in Bloomingdale and Black Creek, GA, we recommend filters with MERV ratings between 8 and 13. These provide excellent protection against:
– Dust mites
– Pollen
– Pet dander
– Mold spores
– Fine dust particles
However, it’s important to note that higher MERV ratings can restrict airflow if your system isn’t designed for them. This is particularly relevant for older HVAC systems in the Ellabell and Meldrim areas.
Regular filter changes are essential for maintaining optimal system performance. During routine furnace service visits, our technicians can help determine the ideal MERV rating for your specific system and home requirements.
Remember, using the correct filter not only improves air quality but also helps prevent unnecessary furnace repairs and extends the life of your heating system.
