How To Clean Or Replace A Dirty Range Hood Vent Filter

Do you frequently cook on your stove or range? Notice a strange grease smell from around the stove area? When you are cooking on your range and you have the vent turned on, all the smoke and grease that is pulled up through the air goes through the vent filter and up and out of your home. Over time this range hood filter will become HEAVILY caked with grease. This grease can begin to stink and the filter itself can get clogged up which can become a safety hazard. If you have not cleaned your range hood filter for years, it may be best to replace it. Here we will show you how to either clean your oven range vent filter or replace it (depending on how bad it is). Our “How-To” on cleaning a greasy oven vent filter is EASY!

I’m having a hard time finding a replacement vent. My Vent is rectangular in shape but then both sides of it turn up. I can’t find any names or numbers on it. What should do.
