Lennox CB28UH-030 Air Filter
It is highly recommended that the filter that filters out particles from your home is swapped out every 3 months for optimal air quality inside the house. The height, length and width of the filter is not really a choice you make because of the constraint of your system. Air Filters are made in lots of varieties and specific sizes, which depends on your particular air quality needs and whether anyone suffers from allergies in the home.

- Manufacturers have recommended to replace the filter every season of the year to keep the air inside clean and free of harmful dust
- Sunlight cannot show through the filter
