Hood Filters & Grease Filters
Commercial exhaust hoods use removable grease filters that you size by width × height to match the filter frames already in your hood, then choose by material — stainless steel lasts longest and washes in the dish machine, aluminum is lighter and cheaper, and galvanized is the budget choice. Baffle-style filters are required over cooking equipment because they separate and drain grease; keep a spare set so you can wash filters nightly without shutting the line down.
Compare commercial hood grease filters by size and material. Every filter here lists its width and height so you can match your hood's frames exactly; pack size is shown where a filter ships in a multi-pack. Confirm your hood requires baffle filters over cooking equipment.
Hood & grease filters: buying guide
Grease filters are wear items — you size them once and replace or wash them forever. The models above filter by size and material.
Get the size right
Filters slot into fixed frames in your hood, sized by nominal width × height (like 16×20″). Measure what's in the hood now and match it exactly.
Material
Stainless steel lasts longest and is dishwasher-safe; aluminum is lighter and cheaper; galvanized is the budget option. Buy a spare set so you can wash filters nightly without downtime.
Fire code
Baffle filters are required over cooking equipment — they drain grease and resist flame spread. Greasy, clogged filters are a leading cause of hood fires and a routine inspection finding.

Frequently asked questions
What size hood filter do I need?
Measure the filters currently in your hood — they're sized by nominal width × height (e.g., 16×20″). Filters slide into fixed frames, so match the existing size exactly; you generally can't mix sizes in one bank.
How often should I clean grease filters?
Baffle grease filters should be washed daily to nightly in heavy use — most are dishwasher-safe stainless or aluminum. Clogged, greasy filters are both a fire hazard and a common health-inspection finding.
Baffle or mesh filters?
Baffle filters are required over cooking equipment: they channel and drain grease and resist flame spread. Mesh filters are only for low-grease applications and are banned over many cooking lines by fire code.
Where do your specs and prices come from?
Specifications are compiled from manufacturer spec sheets and authorized dealer listings; where a value isn’t published we leave it blank rather than guess. “Street price” is the lowest legitimate published price from an online dealer we track for that exact model — equipment only, and it changes often. Many models here have no published online price and show “check dealer pricing.”
Does this equipment need to be NSF listed?
Storage and dish-room equipment used in a commercial kitchen is generally expected to be NSF/ANSI listed for cleanable, food-safe construction — that’s what a health inspector checks on plan review. We don’t assert a listing for a specific model unless the manufacturer publishes it; confirm the exact model’s listing when you permit your kitchen.
About this data
Last verified: August 2026. Specs are compiled from manufacturer spec sheets and authorized dealer listings; where a value isn't published we leave it blank rather than guess.
Methodology: every hood filter model is compared on the same set of specifications, and dimensions are checked (for sinks, overall width must exceed the combined bowl widths) — figures that fail validation are corrected from the manufacturer model number or omitted. “Street price” is the lowest legitimate published price we've found and can change.
Sourcing: product specs come from the manufacturer; regulatory statements link to the source (e.g. the FDA Food Code and NSF). Code requirements vary by jurisdiction — confirm with the authority reviewing your plans.
