Buyers guide for furnace filters

In today’s tightly-packed and compactly-built homes, it’s easy for dust, dander and allergens to get trapped. These types of contaminants can easily irritate the respiratory system and are potentially hazardous – in fact, poor indoor air quality is ranked as one of the top five environmental risks to public health, so it’s a crucial element to focus on if you’re trying to improve your health. There are many furnace filter options on the market, so understanding what to look for will ensure you get the right product for your needs.

The size of the filter is the first factor to check – you want to ensure that the filter you’re replacing is an exact match so that it doesn’t impact the efficiency of the system. This includes the thickness of the filter and its ability to remove airborne contaminants. There are two sizes of standard filter thicknesses to choose from – 1” and 4”. The MERV rating also impacts the efficiency of the air filter – a higher MERV rating will mean you have a finer filter, which will be more effective at removing contaminants and particles. The standard home air system can remove airborne particles with a filter ranging from 6 to 13. The Microparticle Performance Rating or MPR ranges from 300 to 1900, which rates the filter’s ability to capture particles smaller than one micron.

Furnace air filters help to improve the air quality of your home or business as well as lowering the cost of energy bills and keeping your environment as clean as possible. These are ten of the best on the market to suit all budgets and air filter requirements.
