Frequently Asked Questions

How important is the exact fit for an air filter in an HVAC?

Air filters should fit snugly in their designated slots. If the size is too small or too large, it leads to gaps that allow unfiltered air to pass through, reducing efficiency.

Is MERV 11 too high for home use?

MERV 11 filters are suitable for residential use. They effectively capture allergens and particles while allowing adequate airflow. It's essential to ensure your HVAC can handle the increased resistance.

Should I buy cheap or expensive air filters for my HVAC?

While cheaper filters may save money upfront, they often don't capture as many particles and may need to be replaced more frequently. Investing in higher quality filters provides better air quality and longer lasting performance.

What's the ideal MERV rating for my air filter?

A MERV rating between 8 and 13 is recommended for residential use. It balances effective filtration of allergens while maintaining sufficient airflow for most HVAC units.

What are the risks of using an air filter that's too big?

If an air filter is too big, it may not fit properly. This leads to air bypassing the filter. It's important to use the correct size to ensure optimal filtration and system efficiency.
