Lennox CB30M-31 Air Filter
Professionals in the industry advise that the filter that filters out particles from your home is swapped out every 3 months for optimal air quality inside the house. Air Filters are made in lots of filtering levels, which all depends on your personal demands for clean air and air handler size requirements. Exact measurements of the air filter can not be a personal choice but rather a requirement of the manufacturer of your system.
Clues to watch for to know your main filter has little life left
- When you hold the filter up to the light, it will not show on the other side a clogged air filter
- The air filter looks very bad and could be replaced soon
- It is highly advised to switch out the air filter in your unit every season of the year to help clean the indoor air
