Air Filters are made in lots of filtering levels, which depends on your particular desire for cleaner air and air handler size requirements. The height, length and width of the filter is not really a personal choice because it is based on the declared size of whoever designed your heating and cooling system. HVAC specialists suggest that the filter is changed every 90 days or so for optimal air quality inside the house.
What to see if the air filter is about to go out?

- It is highly recommended to switch out the air filter in your unit every season of the year for to keep the air inside the house cleaner
- Sunlight is unable to penetrate through the filter
