Hood Filter Cleaning in Bradford
Bradford Hood Cleaning Pros is a hood filter cleaning contractor working on the baffle filters that sit across the front of a commercial exhaust hood and separate grease from the airstream before it reaches the duct. Every filter is pulled, degreased, checked for warping and correct sizing, then refitted the right way up. Anything warped, corroded, wrongly sized or made of mesh is reported rather than quietly put back. Included in the full-system visit from $385.
The filter bank is the only thing standing between your cook line and your duct
Baffle filters work by forcing the airstream to change direction sharply, so grease droplets hit metal and drain rather than travelling on into the duct.
That mechanism is entirely mechanical. There is no medium to wear out and nothing to power. What there is, is a set of conditions the filter needs in order to work: it has to be the right size for the track, seated at the correct angle, fitted the right way up so the drain channels point down, and clean enough that air still passes through it.
Break any one of those and grease goes up the duct instead of into the trough. That is why the filter bank is the highest-leverage part of the system and the part most often found wrong on a first visit. A gap of even an inch beside a wrongly sized filter is a bypass, and air takes the easy route every time.
Baffle filters vs mesh filters: only one belongs over a cook line
Baffle filters are the correct grease filter for a commercial cooking hood, and mesh filters are still found in Bradford and York Region kitchens where someone bought on price.
| Aspect | Baffle filter | vs. mesh filter |
|---|---|---|
| How it separates grease | Forces sharp direction changes so droplets strike metal and drain to the trough. | Traps grease in layers of wire mesh, holding it in the airstream rather than draining it away. |
| Behaviour in a flare-up | Designed to resist flame passing through into the plenum and duct. | Holds saturated grease directly above the cook line. This is the reason they are not used. |
| Cleaning | Degreased and reused for years. A baffle filter is a long-life component. | Difficult to clean through, and mesh degrades and sheds with repeated cleaning. |
| Where it belongs | Every Type 1 hood over grease-producing equipment. | Not over a cook line. Where one is found, it is reported for replacement. |
Mesh filters over a fryer or char grill turn up more often than you would expect, usually bought online by size and price without anyone checking the type. Where they are found, they are flagged in the written report, because refitting one is not a defensible thing to do. The hood type question is covered on the NFPA 96 guide.
The four filter faults found most often on a first Bradford visit
Wrong size, wrong orientation, warping, and a track packed hard enough that nothing seats properly.
Wrong size. Filters are bought by whoever was there at the time, and a 20-inch unit in a 16-inch track leaves a gap that air pours through. Every filter gets measured against its track on the first visit, and the correct sizes are listed in the report so the next reorder is right.
Upside down. Baffle filters have a top and a bottom, because the drain channels have to point down into the trough. Inverted, the filter still looks fitted and still catches grease, but it holds it instead of draining it. This is the single most common fault, and it costs nothing to fix.
Warping and corrosion. Repeated heating and cleaning eventually bows a filter frame, and once bowed it no longer seals against its neighbours. A bowed filter is not repairable and gets reported for replacement with the measurement attached.
A packed track. If the baffle track is full of hardened grease, filters sit proud of where they should and lean at the wrong angle. Cleaning the track is part of the hood clean, and it is the reason filters that have been "cleaned" repeatedly can still be sitting wrong.
How much do hood filters cost to clean or replace in Bradford in 2026?
Filter cleaning is included in the full-system visit from $385, and replacement filters are quoted per unit by size after measurement.
Cleaning is not charged separately, because pulling the filters is how the plenum behind them gets reached. Any visit that cleans the plenum has already handled the filters.
Replacement is different, and it is quoted per unit against the measured size rather than estimated. That matters because the wrong size is the fault being corrected, so guessing at it would repeat the original mistake. The report lists every position, the size that belongs there, and which units need replacing, which also means the kitchen can order its own if it prefers.
Some heavy fry lines benefit from a mid-cycle filter service between full visits. That is a genuine option rather than an upsell, and it only makes sense where the filter bank is the constraint. The walk-through will say whether that applies. Call 365-809-0864 or use the contact page, and see the cost guide for the full breakdown.
Hood filters: frequently asked questions
What kitchens ask about the filter bank.
Can my staff put the filters through the dishwasher?
Many kitchens do, and it helps between professional visits, though it has limits. A commercial dishwasher shifts surface grease but does not reliably clear the internal channels where a baffle filter does its actual work, and repeated hot cycles accelerate warping. The bigger risk is what happens next: filters come out of a rack and go back in whichever way round they land. If your team does wash them, the one thing worth training is the orientation.
How do I know if my filters are the right size?
If you can see daylight or a gap between filters when the bank is fitted, they are not. On a first visit every filter is measured against its own track and the correct sizes are listed in the report, so the next order is right. Sizes vary along a single hood more often than people expect, which is how mismatched banks accumulate over the years.
How often should filters be cleaned?
The professional clean follows the system interval, so quarterly on a heavy fry line and semi-annual on a moderate kitchen. Between those, in-house washing on a weekly or fortnightly rhythm keeps the bank breathing on a high-volume line. A blinded filter bank reduces the air the hood moves, which shows up as poorer capture and a warmer kitchen before anyone thinks about compliance.
Do I need to replace filters, or can they just be cleaned?
Baffle filters are long-life components and most clean up indefinitely. Replacement is for physical faults: a bowed frame that no longer seals, corrosion, a damaged baffle, or a unit that is simply the wrong size for its position. Those are reported with photographs and measurements rather than replaced automatically, because it is the operator's call and the filter is theirs.
Are mesh filters actually against the rules?
Mesh filters are not the correct grease filter for a Type 1 hood over grease-producing equipment, and a fire inspector who sees one will raise it. The practical problem is simpler than the code question: mesh holds saturated grease in the airstream directly above the cook line, which is the one place you least want it. Where a mesh filter is found, it is flagged for replacement and not refitted.
