Instructions to Properly Install and Replace Your 3M Filtrete™ Air Filter
Check out our easy, step-by-step installation instructions:
Remove and clean the plastic mesh screens.
Place the 3M Filtrete™ Air Filters vertically onto the center of the plastic mesh screens. Allow gaps on each side.
Use the double-faced adhesive tape to attach the filter to the mesh screens.
Install the plastic mesh screens with 3M Filtrete™ Air Filters back into the air conditioner.
For maximum effectiveness, we recommend you change your filter once every 1-3 months for best results. You may want to change the filter more frequently if:
- You are remodeling or there is any other kind of construction work in progress
- There is any furniture or drywall sanding in process
- You own pets
- Anyone in the home smokes
- There is a fan running continuously
