Air Filters exist in many different filtering levels, depending on your demands for clean air and the specific size of filter you need for your system. The height, length and width of the filter is not a choice of options due to the requirement of your furnace or handler. It is suggested the your furnace filter is exchanged for a new one every 3 months to maintain the best air quality in the home.
Subtle hints your filter has very little life left
- It is advised to switch out the air filter in your unit every season of the year to keep the house clean and less dusty
- The filter looks gray or brown and maybe should be replaced right now
- Sunlight cannot penetrate through a dirty filter

Before you decide on buying or purchasing, do your due diligence and make sure of the correct model as well as make a visual inspection so that you are positive that the right air filter is being ordered. There is no rule that says you have to install the replacement part alone. Search for a pro in your town or city to replace the part.
