While we thought winter was over last week… we quickly remembered we live in Minnesota and winter is over when it says so! Our furnace probably enjoyed the quick break last week as well.. because it has had a long hard winter working to keep you in comfort with these record setting low temps!
Because the furnace has gotten quite a workout these last few months… it is important that you keep it in good shape as we finish out the winter. Here are some of the most frequently asked questions we get @ Arctic Mechanical from our Mounds View, MN clients:
When should I change my filter?
There are so many sizes and choices.. which filter is right for me?
Consider these tips for choosing air filters when it comes time for a replacement:
Clean air delivery rate (CADR) is a system used to show consumers the percentage of particles removed from a space multiplied by the cubic feet per minute (CFM) flow of air through the filter. This rating gives you a general idea of how well the filter removes particles while maintaining airflow.
Minimum efficiency reporting value (MERV) ratings show an air filter’s general ability to trap particles of varying sizes. Ranging from 1 to 16—only high efficiency particulate air (HEPA) filters score higher—it’s generally true that air filters with higher MERV ratings trap more and smaller particles; however, as the rating goes up, the filter’s ability to ensure airflow through the media goes down. Compare MERV ratings by also assessing the pressure-drop rating, a designation that shows how much airflow the filter allows through it.
