Filter Cleaning & Replacement

Restore Airflow • Improve Safety • Ensure NFPA 96 Compliance

Your hood system’s baffle filters play an essential role in the performance and safety of your entire kitchen ventilation system. As the first line of defense against airborne grease, smoke, and cooking particles, these filters capture the majority of grease before it has the chance to enter the ductwork. When maintained properly, they reduce fire hazards, protect your exhaust fan, and help keep your kitchen air clean and breathable.

Over time, however, grease accumulates on the surface and inside the channels of the baffle filters. As this buildup thickens, the filters lose their ability to trap grease effectively. Once airflow becomes restricted, your hood system must work harder, leading to reduced ventilation, increased odors, louder fan noise, and heightened risk of a grease-fed fire. This is why regular professional cleaning—and timely replacement when necessary—is crucial for any commercial or residential kitchen.

At Aurora Kitchen Hood Cleaning, our Filter Cleaning & Replacement service ensures that your hood system filters remain clean, functional, and fully compliant with NFPA 96 fire-safety standards. Whether your filters simply need a thorough deep cleaning or are worn out and need to be replaced, we provide the expertise and high-quality products to keep your kitchen protected and operating at peak efficiency.

⭐ Why Baffle Filters Are So Important

Although they might seem like simple metal pieces, baffle filters are one of the most critical safety components in your hood system. Their purpose is not just to catch grease for cleaning convenience—their design helps prevent flames from traveling upward into the ductwork.

Here’s why they matter:

✔ Fire Prevention

Clogged filters allow grease to bypass the baffles and enter the ductwork. Once inside, grease buildup becomes a severe fire hazard. Clean filters drastically reduce the risk of ignition and flame travel.

✔ Improved Airflow

Filters packed with grease restrict air movement. Clean filters restore airflow, allowing your exhaust fan to operate efficiently without strain.

✔ Better Odor & Smoke Control

When airflow is blocked, smoke and odors linger in the kitchen. Clean filters help remove contaminants more effectively.

✔ Protection for Exhaust Fans & Ducts

Dirty filters allow grease to pass through the system, accumulating deeper where cleaning is more difficult and expensive.

✔ Regulatory Compliance

NFPA 96 requires that filters be maintained in good working condition. Clean, undamaged filters help ensure your kitchen passes inspections.

Because filters play such a central role in the ventilation system, their maintenance should never be overlooked.

⭐ Our Filter Cleaning & Replacement Process

We follow a detailed, multi-step process to ensure your filters remain in excellent condition or are replaced when necessary.

✔ Inspection & Evaluation

We begin by inspecting your filters for grease, dents, warping, corrosion, or other structural concerns that may affect performance or safety. This initial assessment helps us determine whether cleaning or replacement is required.

✔ Deep Cleaning of Stainless Steel Baffle Filters

Using commercial-grade degreasers and high-temperature cleaning methods, we break down and remove stubborn grease deposits inside the filter channels. This process restores the filter’s ability to capture grease and improves airflow throughout the hood system.

✔ Removal of Grease, Residue & Blockages

Filters often accumulate thick layers of grease inside the baffles. We use safe but effective cleaning solutions to remove these blockages, ensuring airflow is fully restored.

✔ Inspection for Damage or Fire-Risk Issues

After cleaning, we inspect the filters again to ensure they are structurally sound. Filters showing cracks, warping, folds, or corrosion may need to be replaced.

✔ Recommendations for Replacement (If Needed)

If your filters are beyond recovery or no longer meet safety requirements, we recommend professional replacement with high-quality, stainless steel baffle filters.

✔ Installation of New NFPA 96–Compliant Filters

We supply durable, commercial-grade stainless steel filters designed for long-lasting performance and fire protection. Proper installation ensures correct airflow direction and optimal efficiency.

✔ Final Airflow Check

Once filters are cleaned or replaced, we verify that airflow through the hood system is restored and that ventilation is functioning properly.

⭐ When Should Filters Be Cleaned or Replaced?

Cleaning frequency depends on your cooking volume:

• High-volume kitchens: Weekly or bi-weekly cleaning

• Moderate-volume kitchens: Every 2 to 4 weeks

• Low-volume kitchens: Monthly or as needed

• Residential kitchens: Every 3–6 months depending on usage

Replacement is generally recommended when filters show:

• Warping or bending

• Corrosion or rust

• Broken or loose baffles

• Permanent grease saturation

• Structural damage

• Heat-related discoloration or weakening

Using damaged or clogged filters can create dangerous conditions for your kitchen.
