AIR FILTRATION CUT TO FIT

Measure the opening you want to filter.
Transpose those measurements to the filter using a marker or pen.
 Cut the filter.
 Apply the filter.
Replace every 30-60 days or when the filter starts to look dirty.

Best Practices: Some applications may require the use of adhesive Velcro dots to secure the filter.

Pro Tip!: Add some drops of your favorite smelling oils to your filter for great smelling filtration!
