The Importance of a Quality Air Filtration System
While our lives will remain busy, and as long as we live in buildings there will be certain gasses we inevitably breathe – there is one simple thing that everyone with a forced air HVAC system can do: choose the right filtration system for its size and design, and for your lifestyle and health needs.
At Just in Time Furnace Inc. in Calgary, we carry a wide variety of filters and air filtration systems. Filters are used on your furnace to catch dust, dirt, and other allergens and require scheduled replacement to ensure air quality in your home. By removing pollutants from the air (both chemical and environmental ones), your family will be able to breathe cleaner air on a daily basis.
The effectiveness of mechanical air filters is measured in MERV ratings (Minimum Efficiency Reporting Value). The cheaper the filter is, the lower the MERV number is or in other words, you get what you pay for and as such, air filters with lower MERV ratings need to be replaced more frequently. A mechanical air filters is any type of dry media filter that remove dust by capturing it on the filter medium, the material that makes up the filter element including all throwaway air filters used in HVAC systems and Air Handlers.
There are four types of mechanical air filters:
Fiberglass: very thin with a simple flat panel surface for trapping particles from the air, originally developed to protect your heating and air conditioning equipment, not to improve your indoor air quality. Very inexpensive but remove less than 10 percent of the air pollutants from your home - MERV rating of 1 to 4.
Pleated: number of pleats per foot impact their overall efficiency, removing up to 45 percent of the air pollutants from your home - MERV rating of 10 to 13.
High-efficiency: most practical air filters for most residential HVAC systems, removing up to 85 percent of the air pollutants from your home - MERV rating of 14 to 16.
True HEPA (or High Efficiency Particulate Air): best filtration for your home, removing up to 98 percent of air pollutants – MERV rating of 17 to 20. They can only be used in a whole house filtration system or a standalone air purifier.
