A good air filter can make a difference in your home’s air quality and your HVAC system’s energy efficiency. It’s important to be aware of different factors when it comes to filters, such as size, price and MERV rating (Minimum Efficiency Reporting Value). This rating is based on how good the filter is at catching dust particles – a rating of 1 means the poorest and 16 the best. The highest MERV rating is not always the best for your furnace. Having a filter that is too restrictive can put additional strain on your furnace. Talk to one of our Home Comfort Advisor to find an air filter that works for your furnace and your home.
