SPT WA-1240H Air Filter
HVAC specialists suggest the your furnace filter is replaced for a clean one every 3 months for optimal air quality inside the house. The measurement proportions of the filter is not really a optional choice but rather a requirement of your furnace or handler. Air Filters come in a wide array of types and sizes, depending on your desire for cleaner air and air handler size requirements.
What red flags are there that my filter is about to go out?
- With a light behind the air filter, the light will not shine through to the other side of a dirt-packed filter
- The air filter looks brown and it would be best to replace it right now
- It is highly recommended to switch out the air filter in your unit about every 90 days to keep the unit running efficiently
