Know before you buy
A MERV 13 rating indicates high-efficiency filtration capable of capturing 98% of airborne particles. It is effective at trapping smaller contaminants like bacteria, smoke, and fine allergens that lower-rated filters might miss.
These filters are engineered with synthetic media that balances high-efficiency capture with low airflow resistance. This design ensures your HVAC system can breathe properly while still maintaining a high level of air purification.
For optimal performance and to protect your HVAC equipment, you should replace these filters every 1 to 3 months. The exact timeframe depends on your home's air quality, the presence of pets, and how frequently your system runs.
Yes, these filters have exact dimensions of 20 inches by 20 inches by 1 inch. They are designed to fit standard whole-house HVAC systems that require this specific nominal size.
The electrostatic charge acts like a magnet for airborne particles, pulling them into the filter media. This allows the filter to capture smaller, microscopic pollutants more effectively than standard mechanical filters without needing a denser, more restrictive material.
