What Makes the 16x20x4 Filter Different?
The 4-inch thickness means a larger surface area to trap more contaminants while maintaining airflow. Compared to 1-inch filters, this model:
Filters more particles per cycle
Needs less frequent replacement
Allows the blower motor to operate with less resistance
Improves long-term system performance
How It Protects Your System and Your Family
Your air filter acts as a shield. When upgraded, it captures:
Dust mites and debris
Pet dander and shed hair
Mold spores and bacteria
Fine smoke particles and allergens
Cleaner air not only improves respiratory health, it also protects HVAC components from buildup that leads to wear, damage, and costly service calls.
