Lennox G43UF-48C-090 Air Filter
It is highly recommended that the filter that filters out particles from your home is swapped out every 3 months so as to maintain good airflow inside the house. Exact measurements of the air filter can not be a choice you make but rather a requirement of your system. Air Filters come in a wide array of filtering levels, which depends on your particular air quality needs and air handler requirements.
Key clues of an ineffective dust filter
- Light will barely shine through to the other side of a dirty filter
- Manufacturers have advised to replace your air filter about every three months in order to keep the air free from too much dust
- The air filter looks very bad and it would be best to replace it real soon
