Ace’s home expert, Lou Manfredini, gives the rundown of the good, better, and best in furnace filters for your home.

Know The MERV Rating When picking out an air filter, make sure you look at the MERV rating. An air filter’s minimum efficiency reporting value (MERV) rating measures how effectively the filter stops dust and other contaminants from passing through the filter and into your home’s system. Filters with higher MERV ratings trap small particles more effectively than filters with lower MERV ratings.

Good Filters, For the most part, fiberglass air filters are safe to use. However, the lack of the fiberglass option having a pleated design lessens the likelihood of it filtering out contaminants that can travel through the system like pollen, pet dander, and bacteria.

Better Filters The next option in filters offers the pleated design, but a lower MERV rating does not offer a solid filtration of particulates that may travel through the filter. Filters in this price range outperform fiberglass, washable, and non-electrostatic 3-month pleated 1-inch filters. They need to be changed frequently.

Best Filters The very best filters have a higher MERV rating, really offering superior protection in your home. These filters will help capture unwanted particles from your household air, contributing to a cleaner, fresher home environment. By proactively capturing dust, bacteria, viruses, and allergens, these high-performance filters help improve your home’s air quality.

Always follow the manufacturer’s instructions before using any product.
