Does spending more money guarantee that you’ll get a superior product? When it comes to your furnace filter, the answer is, “It depends!”
Filters are rated using Minimum Efficiency Reporting Value (MERV) – the higher the MERV rating, the better the filtration and usually the higher the cost.
A good rule of thumb is to change 1″ filters every 30-60 days, and 4″ filters every 4-6 months. Most 1″ filters that achieve higher MERV ratings are also more likely restrict airflow, which starves your HVAC equipment for air. So the “Cheaper is better” principle is somewhat true.
According to the heating and cooling experts at Stay Comfy, Minnesota, the best way to achieve superior filtration is to upgrade your 1″ filter to a 4″ filter. This usually requires professional modifications to your ductwork. Ask your Minnesota HVAC company for a free estimate for this simple upgrade.
