Thats also misleading. That is the max life. So if ou have a dirty house, leave the windows open,pets, duct work in and attic or crawl space, loose construction house etc they don't last as long.

Do you have central air conditioning? If so having a dirt filter can cause the coil to gt dirty causing issues as well.

Folks - PSA!!!! If you use a $5 filter or less and change it monthly, it will more than save you that on your utility bill.
