RANGE HOOD · REPLACEMENT IDENTIFICATION
How to measure and identify a replacement range hood filter
Grease filters and charcoal filters have different jobs. An exact-looking frame can also have the wrong latch or attachment tabs. Record what is actually installed, then check the hood maker’s replacement parts list before ordering.
Start with the full hood model and any part number stamped on the old filter. If those are missing, note the filter material, frame dimensions and fastening system. A measurement alone cannot establish a compatible replacement.
Use the identification worksheetWhich filter are you trying to replace?
Do not assume a charcoal filter is present just because the hood is sold as “ductless capable”. The actual installation, conversion kit and manufacturer instructions determine the required parts.
Metal mesh or baffle grease filter
Captures cooking grease. Many metal filters are designed to be cleaned and reused, subject to their manual. A bent frame, missing latch or damage may require replacement.
Record: width, height, frame thickness, latch/tabs and count.
Charcoal / carbon filter
Used in specified recirculating configurations to reduce odors. It is not a substitute for a grease filter and is generally replaced rather than washed.
Record: maker’s part number and whether the hood has the required recirculation kit.
Combination or unknown filter
Some designs combine functions, while others use separate metal and charcoal elements. The visible panel alone does not establish which configuration your hood uses.
Record: all markings and check the exact installation manual.
How to measure the old range hood grease filter
- Confirm safe access. Let the cooktop and hood cool, switch the hood off, and follow the user-maintenance instructions. Do not remove electrical covers or work on wiring.
- Measure the complete outer frame. Record the filter’s actual external width, height and thickness, including its permanent frame, not just the inner mesh or the hood opening.
- Inspect the fastening. Photograph or describe spring tabs, slide-in edges, handles and which side latches. Similar dimensions with different attachment mechanisms do not prove a fit.
- Check how many panels are installed. Record the count and whether they are identical; the hood’s advertised 30-inch or 36-inch width is not the individual filter’s width.
- Confirm against documentation. Find the manufacturer’s exact parts drawing for your full model. If a listing’s dimensions or latch differs, stop and ask the manufacturer or a qualified parts supplier rather than forcing it.
Never cut, bend or force an incompatible replacement to make it fit. If the existing part is missing or was previously installed incorrectly, measuring that old part is insufficient: prioritize the hood’s model-specific parts list.
STEP-BY-STEP IDENTIFICATION TOOL

Use the existing filter and the range hood’s own model label. Your answers stay in this browser tab; the form does not upload or save them. Leave unknown information blank.
YOUR NEXT CHECKS
What you can establish from these observations
Current measurement state: not recorded. This tool does not select or certify a replacement.
- Find the full hood model number on its label or in its manual; the hood width alone does not identify its filter.
- Look for a manufacturer part number on the existing frame or in the parts diagram.
- Record the existing filter’s external width, height and frame depth, without assuming a rounded nominal size.
- Identify the latch, tabs and frame geometry, not just the width and height.
- Record the actual number of filters in the installed assembly rather than guessing from the hood width.
- Check the hood manual to establish whether your actual installation exhausts outdoors or recirculates.
- Compare your recorded observations with the manufacturer’s exact replacement parts list. Size or appearance alone never proves fit.
Copy the record when asking the manufacturer or a repair-parts supplier about an exact OEM replacement. Do not send serial numbers, addresses or payment details.
Check these four things before ordering
1. Hood model: not just the brand or nominal hood width.
2. Filter function: grease, carbon, combination, and actual ducted/recirculating setup.
3. Physical detail: actual outer frame, fastening geometry, orientation and quantity.
4. Manufacturer evidence: exact replacement number or an explicitly documented equivalent.
Not sure how to identify a part on a furnace or air-cleaner cabinet instead? Use our HVAC identification guide. That service does not verify range hood filter fit.
