International Comfort Products HAC060GKA4 Air Filter
Professionals in the industry advise the your furnace filter is changed every 90 days or so to maintain the best air quality through the ducts. Filters come in many varieties and specific sizes, depending on your choice for how clean you want the air and air handler size requirements. The height, length and width of the air filter can not be a choice you make due to the constraint of the availability of room of your furnace or handler.
Symptoms of a deteriorating main filter
- Professionals have recommended to replace the filter four times a year in order to have clean air running through the unit
- As you face it toward a light source, it is unable to show on the other side a dirty filter
- The system filter looks gray or brown and could be replaced as soon as you can
