Grease Lock Slows Grease Buildup

A patented, disposable filter pad and metal frame with a built-in baffle on back. Features unique fire-resistant fiber, delivering exceptional grease filtration efficiency.

Grease Lock is a patented disposable filter pad and metal frame that is used in place of traditional baffle filters. It features a unique heat-resistant fiber, designed to deliver exceptional grease filtration.

Grease Lock is the First Line of Defense

Grease Lock is your first line of defense in reducing risk of flames entering the hood and flue. The patented disposable filter pad and metal frame reduces frequency of hood cleaning, maintenance on the roof, and baffle filter cleaning. It addresses all life stages of grease as it travels through your kitchen exhaust system. Our product is designed to capture and remove a high percentage of the total grease particulate emissions produced during commercial kitchen cooking operations and is constructed of an all-natural, heat-resistant fiber that is sustainable. We have developed the perfect balance between grease filtration and airflow resistance within our Grease Lock product.

Benefits of Grease Lock

Increases Roof Life

Grease Lock captures the grease before it enters the exhaust system, reducing the grease particles emitting through the rooftop fan. The necessity of rooftop containment systems is virtually eliminated. This can result in cost savings while potentially extending the life of the roof itself.​

Increases Fire Safety

Grease Lock filters capture the grease before entering the exhaust system. This greatly reduces the contaminants that enter the exhaust hood, duct work, fans and roofs, helping to reduce the risk of a catastrophic fire.

Saves Labor

Many commercial kitchens clean their baffle filters nightly or weekly. With Grease Lock filters, the metal baffle filters need to be cleaned only once a month.

Compostable & Sustainable

Grease Lock filters are all natural. The filter media is carbon-neutral and will break down in the landfill along with the internal support frame.​

Reduces Hood Cleanings

Hood and duct cleaning is reduced by nearly 75% of the current cleaning frequency…less frequent cleaning means less inconvenience, labor and expenses. For 24-hour kitchens, it also means fewer business interruptions.

Saves Water & Chemicals

Reducing the current exhaust/hood cleaning schedule along with reduced baffle filter cleanings greatly reduces the amount of water and chemicals used to maintain a clean system.

How to Order Grease Lock




Measure your existing hood baffle filters, record the measurements. Grease Lock filters are available in most industry standard sizes.

Configure your order by selecting the correlating sized Grease Lock Frames. Next select matching sized grease lock filters – Filters are sold in a case QTY of 40 filters per case. Reminder – don’t forget to add any additional accessories as needed.

Submit your order once you have selected the QTY and sizes of Grease Lock Frames and Filters. Click on the view cart button at the top of the screen. You will see an order summary and an order form. Complete the order form, then submit your order request.

How to Choose the Right Filter Size

Now that you know why hood filters are needed, the next step is to determine the correct size. If you’re purchasing filters for a new hood system, you will also need to figure out how many filters are required to fill the open hood space. These are the most common questions we receive so we’ve created several tools to make this as simple as possible.

Measuring Existing Hood Filters

Industry standard sizes are stated with the vertical (top to bottom) dimension first and the horizontal (left to right) dimension second. The baffles should run up and down (vertically) when taking these measurements (see diagram below).

Remember: Height First, Width Second.
Trade Size Actual Dimensions
10” x 16” 9-1/2” x 15-1/2”
10” x 20” 9-1/2” x 19-1/2”
16” x 16” 15-1/2” x 15-1/2”
16” x 20” 15-1/2” x 19-1/2”
20” x 16” 19-1/2” x 15-1/2”
20” x 20” 19-1/2” x 19-1/2”

NOTE: Always round up to the nearest ½”. Actual filter size is typically ½” smaller than the stated size. For example, if the actual filter size is 9 ½” x 15 ½”, you would order a 10 x 16 hood filter.

Measure height (up & down with the baffles) and width (across the baffles), then record quantity below.
