When it comes to your home’s comfort and air quality, few things are as important as selecting the right air filter for furnace. At HVAC Service Solutions, we understand that choosing the best air filter is not the easiest task. Confusing terminology, a wide array of filter options, compatibility with your type of furnace — all of this makes the decision pretty confusing. This is why we are here to equip you with all information you need to know about furnace filters in Canada, their types, and factors to consider when choosing the perfect unit.
Key Terms You Should Know About Air Filters
Before we jump to the different types of air filters, it’s essential to equip ourselves with some key terms that will help demystify the selection process. Understanding these terms is like having a roadmap to navigate through the various options and make an informed decision.
MERV (Minimum Efficiency Reporting Value): MERV, often referred to as the “report card” for air filters, rates the effectiveness of filters in capturing particles. Ranging from 1 to 20, the higher the MERV rating, the more efficient the filter is at trapping tiny particles like dust, pollen, and pet dander. For everyday household use, a filter with a MERV rating of 8 to 13 strikes a good balance between filtration efficiency and airflow.
HEPA Filter (High-Efficiency Particulate Air): Imagine a HEPA filter as the ultimate super-hero of air filtration. These filters are designed to capture particles as small as 0.3 microns with an impressive efficiency of 99.97%. If you or your loved ones suffer from allergies or asthma, a HEPA filter can significantly improve your indoor air quality by trapping even the tiniest of irritants.
Activated Carbon Filter: Think of activated carbon filters as odor detectives. They specialize in absorbing and neutralizing unpleasant odors and harmful gases. These filters are commonly used in situations where bad smells or potentially harmful gases need to be eliminated, making them an excellent choice for homes with cooking smells, pet odors, or even urban pollution concerns.
MPR (Microparticle Performance Rating): If MERV is the report card, then MPR is the detailed performance breakdown. MPR measures a filter’s ability to capture particles in the range of 0.3 to 1 micron in size. The higher the MPR, the more efficient the filter is at capturing these small, sneaky particles that often evade other filters.
FPR (Filter Performance Rating): FPR rates filters on a scale from 4 to 10, considering factors like filter efficiency, airflow, and dust-holding capacity. This rating system aims to provide a more holistic view of a filter’s overall performance, helping you make a well-rounded choice based on your specific needs.
