Hood Filter Cleaning Service in Concord & the GTA

✔ NFPA-96 Certified   ✔ Before & After Photo Documentation   ✔ Same-Visit Airflow Check   ✔ Serving Concord & the GTA

Hood filters are your kitchen’s first line of defence against grease, smoke, and airborne contaminants — but they’re only effective when they’re clean. Hood Cleaning Masters provides professional grease filter cleaning for commercial kitchens across Concord and the GTA, restoring airflow and keeping your system compliant with NFPA 96. Filter cleaning is included in every full commercial exhaust hood cleaning visit, or can be scheduled as a standalone service between full cleanings.

Why Filter Cleaning Matters in Commercial Kitchens

Filters act as the primary barrier between your cooking line and the rest of the exhaust system. Over time, airborne grease settles on their surface and hardens into thick residue if left unaddressed. That buildup:

  • Restricts airflow — clogged filters make your exhaust system work harder and reduce its ability to clear heat, smoke, and odours.
  • Raises fire risk — grease is highly flammable, and a filter caked in residue is exactly the kind of fuel source fire inspectors look for.
  • Degrades air quality — poor filtration means more smoke and contaminants lingering in the kitchen.
  • Increases operating costs — dirty filters put extra strain on your exhaust fan, leading to more frequent repairs and higher energy use.

Under NFPA 96, filters are one of the specific components inspectors check for grease accumulation, and they’re referenced directly in the Ontario Fire Code, O. Reg. 213/07 as part of a commercial kitchen’s exhaust and fire protection system.

Baffle Filters vs. Mesh Filters

Most commercial kitchens use one of two filter types, and each has a slightly different cleaning approach:

  • Baffle filters — the standard in most commercial kitchens today. Their angled metal design traps grease through directional airflow and holds up well to repeated degreasing and washing.
  • Mesh filters — layered metal mesh that filters grease as air passes through. They require more frequent cleaning since mesh clogs faster than baffle design, and are less common in new commercial installations.

Our technicians identify your filter type during inspection and clean accordingly — baffle and mesh filters don’t respond the same way to the same technique, so a one-size-fits-all approach leaves residue behind.

What Our Filter Cleaning Service Includes

1. Detailed Inspection

We assess your filters’ current condition to determine buildup level and the right cleaning approach for your filter type.

2. Grease & Residue Removal

Using industry-grade degreasers and specialized equipment, we remove grease and contaminants from all filter surfaces to restore proper airflow.

3. Sanitization & Rinse

Filters are rinsed and sanitized after degreasing to eliminate odours and leave a hygienic surface that won’t reintroduce contaminants into the air.

4. Reinstallation & System Check

Cleaned filters are reinstalled correctly, and we check the system for airflow performance before finishing.

5. Maintenance Recommendations

We provide a cleaning frequency recommendation tailored to your kitchen’s cooking volume, so you’re not guessing at your next service date.

Benefits of Professional Filter Cleaning

  • Improved Airflow & Ventilation Efficiency — clean filters let your exhaust system remove smoke, heat, and odours the way it’s designed to.
  • Reduced Fire Hazards — removing accumulated grease lowers the risk posed by highly combustible residue.
  • Better Indoor Air Quality — fewer airborne contaminants means a healthier environment for staff.
  • Lower Maintenance & Operating Costs — less strain on fans and ventilation components extends equipment life.
  • Regulatory Compliance — well-maintained filters support NFPA 96 and fire code compliance, helping you avoid fines or citations.

Who Needs Regular Filter Cleaning?

Professional filter cleaning suits any commercial kitchen where cooking produces grease, smoke, or odours, including:

  • Full-service restaurants
  • Cafés and bakeries
  • Hotels and banquet kitchens — see our commercial exhaust hood cleaning page for full-system service
  • Food trucks and mobile kitchens — see our food truck hood cleaning page
  • Catering facilities
  • Institutional kitchens (schools, hospitals, and similar operations)

How Often Should Your Filters Be Cleaned?

Daily and weekly wipe-downs help maintain filter condition between services, but professional cleaning should follow a set schedule based on cooking volume:

Cooking type / volume

Typical cleaning interval

High-volume cooking (deep frying, heavy grease)

Every 1–3 months

Moderate-use kitchens

Every 4–6 months

Low-volume cooking spaces

At least once a year

A custom recommendation and service schedule is provided after your initial inspection.

Filter Cleaning Cost

Pricing depends on the number of filters, filter type, and buildup level. Filter cleaning is often bundled into a full hood cleaning visit at a lower combined cost than booking separately, but standalone filter service is also available if you need it between full cleanings.

Extend the Life of Your Kitchen Ventilation System

Clean filters are foundational to a clean kitchen ventilation system — they protect your equipment investment and keep your team working in a safer environment. Left unaddressed, filter buildup can damage components further down the system, including your exhaust fan, driving up repair and energy costs over time.

Frequently Asked Questions

High-volume kitchens doing deep-fat frying should clean every 1–3 months, moderate-use kitchens every 4–6 months, and low-volume kitchens at least once a year.

Look for visible grease or dust buildup on the filter surface, reduced airflow, lingering odours, or a smoky smell — all signs cleaning is overdue. Your service sticker will also show your next due date.

Baffle filters use an angled metal design and are standard in most modern commercial kitchens. Mesh filters use layered metal mesh, clog faster, and need more frequent cleaning. We identify your filter type and adjust our technique accordingly.

Yes. We provide an NFPA 96 certificate and sticker confirming your filters have been cleaned to the mandated safety standard.

Standalone filter cleaning is typically faster than a full hood cleaning — most jobs take 1 to 3 hours depending on filter count and buildup, though this can extend to 3-6 hours when bundled with a full system clean.
