Choosing a Quality Air Filter

Many homeowners may know that air filters are a part of their HVAC system, but they may not know just how important air filters are to the health and wellbeing of everyone in the house. Air filters should be changed at least four times a year, but they should be changed more frequently when the air conditioner is being used, such as during the summer. With this in mind, how can homeowners know which air filters boast the best quality?

Air filter effectiveness is measured by Minimum Efficiency Reporting Value, or MERV. The higher the MERV number, then the better quality the air filter will be. The best air filters to protect indoor air quality are high-efficiency air filters, which usually have a MERV rating of 14 to 16. Another quality filter is a High Efficiency Particulate Air, or HEPA, filter. This will have a MERV rating of 17 to 20. With any selection you make, ensure that the filter is meant for the home’s system before installing.
