Types of Trane Air Filters Available

Our replacement air filters make excellent options for Trane AC air filter and furnace filter replacements. The most important factor in choosing your Trane air filter replacement is to select the correct size for your system. To find the right size of compatible filter, check your system manual, consult with a professional, or measure your old filter. Most filters come in nominal sizes, which is the actual size rounded up to the nearest whole number, so keep that in mind as you peruse your Trane air filter replacement options. Another option to consider is the MERV rating. Most households can use a MERV 8 filter, but those with pets or allergies may benefit from an upgrade to MERV 11. For enhanced filtration, you may wish to upgrade to a MERV 13 filter, but make sure your system can handle the increased filtration before purchase. Keep in mind a higher MERV rating may also require increased filter replacement to keep your system running efficiently.

Trane Air Filter Replacement – How Often and Why?

How often you replace your Trane air filter depends upon filter thickness, MERV rating, and personal household factors like if you have allergies or pets. Filters that are 1 to 2 inches thick will need replacement more frequently than thicker 5 or 6 inch whole house filters. MERV 13 filters will need to be changed more often than MERV 8. In general, be prepared to change HVAC filters every 3 to 6 months, and furnace or AC only filters every 6 to 12 months. If you fail to maintain your filter replacement, the filter can become clogged causing reduced air flow through the system. This reduced flow can then put strain on your system, creating less efficiency and potentially more expensive problems down the line.
