Hood Fan Filters & Commercial Grease Filters for Kitchen Exhaust Hoods
Baffle, mesh and Nano hood filters in 201/304/430 stainless steel — Type U series UL certified, OEM sizes and handles, supplied factory-direct and at wholesale from Foshan, China.

Three structures, one job: keep grease out of your ductwork
Cooking grease that escapes the hood settles in fans and ducts, raising fire risk and maintenance cost. Choose the structure that matches your cooking load.

Baffle (Z-type)
Z-profile baffles spin grease out of the airstream. Best for heavy frying and grilling lines; easy to run through a dishwasher.

Mesh / Louver
Layered mesh panels for moderate cooking loads and light-commercial hoods, with low airflow resistance.

Nano
Fine nano mesh media captures finer grease particles for cleaner ducts where filtration efficiency matters most.

Kitchen Exhaust Filters: Sizing, Replacement and Wholesale Buying
Practical guidance from our export team for hood OEMs, kitchen contractors, restaurants and equipment distributors.
Kitchen exhaust filters are specified by three numbers: the hood channel length and width the panel must fill, and the frame depth that matches the filter track. Measure an existing panel or the empty channel — our standard grid covers the common 20x16, 20x20 and 25x20 inch formats used on hoods worldwide, and non-standard sizes are cut to order as OEM production.
Filters for commercial hoods: which structure
For filters for commercial hoods over solid-fuel grilling or heavy wok lines, baffle (Z-type) panels are the code-preferred choice: they spin grease out of the airstream and tolerate daily dishwasher cleaning. Light-to-moderate cooking suits mesh/louver panels, and where duct cleanliness is critical, Nano media captures finer particles. The Type U series is UL certified for North American inspections.
Grease filter for vent hood replacement
Looking for a grease filter for vent hood replacement? Send the model stamp, a photo with a tape measure, or the hood brand and channel size. Most replacements ship against our standard tooling, so lead time stays short; mismatched panels leave gaps that let grease bypass into the duct, so exact sizing matters more than price.
Wholesale and OEM supply
We supply hood manufacturers, distributors and wholesalers at factory-direct pricing, MOQ 100 pieces per model with mixed sizes allowed. OEM options include custom lengths, handle positions, finishes and private-label packaging, with export cartons and full shipping documents from our Foshan, China factory.
Hood Fan Filters & Hood Filters FAQ
The questions buyers, distributors and hood OEMs ask us most often about kitchen exhaust hood filters and hood filter replacement.
What is the difference between baffle and mesh grease filters?
Baffle filters use Z-shaped channels that spin grease out of the airstream and are the standard for heavy commercial cooking. Mesh filters use layered mesh panels, suit lighter cooking loads and cost less, but need more frequent cleaning.
Are your grease filters UL certified?
The Type U series is UL certified for the North American market. Other models are built to the same production standards; tell us your market and we will confirm the certification package you need.
Which stainless steel grade should I choose?
201 for cost-sensitive dry environments, 430 for typical commercial kitchens, 304 for coastal or high-salt, heavy wash-down environments. Send us the kitchen environment and we will recommend a grade.
Can you make filters in custom sizes?
Yes. Length, width, frame depth, handle position and finish are all customizable. Send hood dimensions or a sample and we will quote within 24 hours.
How do I clean a baffle grease filter?
Remove the filter by its handle, soak in degreaser or run it through a commercial dishwasher. Baffle filters tolerate daily machine washing; mesh filters should be soaked rather than scrubbed.
What is the minimum order quantity?
MOQ is 100 pcs per model, mixed sizes allowed. Sample orders are accepted before bulk production.
Need filters sized to your hood?
Send us hood dimensions or a sample — we manufacture baffle, mesh and Nano filters to your sizes, with handles and frames to match.
