This is a permanent, all-aluminum mesh grease filter. Your service life is extended due to the staggered baffle pattern while catching 92% of the grease particles. This allows the grease to depth load which gives you a longer time span between cleanings, keeps your cooking surface cleaner and prolongs the life of your range hood. Simply clean using warm water and dish soap.
These are replacements for Broan, NuTone, General Electric, Gremline and Rangeaire range hoods.
