What are MERV 11  Carbon Defense Air Filters & Furnace Filters?

MERV 11 Carbon Defense air and furnace filters are similar to traditional MERV 11 filters, but feature an active carbon layer. These powerful filters can promote clean air while getting rid of unwanted odors. As you browse the selection of air and furnace filters, you may be wondering what MERV rating and features are appropriate. While there’s no harm in going with a higher rated filter, they can vary in price. The size of the filter can also impact the price. Here are some reasons to opt for a MERV 11 air and furnace filter with carbon defense. 

  • Allergies, asthma, and other health issues: If you have allergies, asthma, or health issues, opting for a higher rated filter can help you breathe cleaner air. The higher the MERV rating, the smaller the particles the filter can trap. In addition to choosing a powerful filter, you’ll want to change it out regularly. 
  • Pets: If you have pets, especially those that shed, a more powerful air filter can trap pet dander, keeping the air you breathe clean. If you have pets in combination with sensitivities or allergies, this can be an even bigger motive to opt for a higher rated air filter. 
  • Smoke: If your space is exposed to smoke, or previously was, a more powerful filter can help absorb smells and filter cleaner air. 

What Is The Difference Between MERV 11  And MERV 11 Carbon Defense?

The difference between a MERV 11 air and furnace filter and a MERV 11 Carbon Defense filter is simply that one has an added layer for carbon defense. The carbon layer works to remove smells and odors from the air you breathe. The carbon layer combined with an already powerful MERV 11 air and furnace filter creates a super air and furnace filter.

How Often Should You Change A MERV 11 Carbon Defense Air Filter?

A MERV 11 Carbon Defense filter may last longer than a lower rated air filter.

While the recommended frequency to change the filter can vary, changing your filter every 3-6 months is a reasonable guideline.

The amount of time you use your HVAC, environment, and other factors can influence the rate that you need a new air filter. Installing or checking your air filter is a rather straightforward task.

If you’re unsure if your air filter needs replacement, check your filter. If it looks dirty, it may be time for a new filter. A dirty filter can still help trap particles, but it can lead to other issues. In addition, it may trap less particles, and or cause particles to be blown into the air.

It can also cause your HVAC system to work harder, leading to repairs and or replacement sooner than expected. Replacing your air filter is part of maintaining a healthy home and HVAC system. With a relatively low price tag, the hardest part about changing a filter is simply remembering to do it.
