Contractor Cornerstones: Filters & Finances

America's Preferred Home Warranty, Furnace Filters, Home Maintenance, Contractor AdviceGetting ready to switch out your furnace filter for the year? It might be time to consider what kinds of filters you could replace it with.

According to Lammers Heating & Air Conditioning President Todd Desy, the primary difference between one filter or another is how efficiently it will remove particles from your indoor air.

“They rate from 1-inch throwaways that just protect the furnace itself (the blower), on up to higher efficiency air cleaners that will actually filter and improve the air quality in your home,” Todd said.

While the minimum filter is cheaper up front, it only truly blocks larger debris (like pet fur or hair) from your HVAC system, allowing smaller particles of dust, mold spores, and other potentially harmful bits to pass through.

Switching from the basic filter to a higher efficiency filter also keeps your furnace cleaner, increasing its lifespan and saving you money in the long run. Though it’s important to ensure you’re not using a filter that’s too strongly woven (which can make your furnace work harder to bring air through).

Regardless of which efficiency level you choose, make sure to select the correct size and shape of filter to fit well in your particular furnace. “The minimum would be a basic mechanical air cleaner that has to be replaced once a year,” Todd said.
