Find the perfect filter to meet your needs.
Restaurants face a unique air quality challenge. In the kitchen, cooking generates heat, grease, smoke, and odors that need to be vented out safely.
In the dining area, the focus shifts to comfort—removing dust, allergens, and lingering smells to keep guests happy. This split demands two filtration approaches: HVAC filters for circulated air and exhaust filters for kitchen hoods.
Each type of restaurant filter is designed to tackle specific contaminants, from fine particles to oily vapors, ensuring compliance with standards.
The HVAC system is the heart of a restaurant’s indoor air quality, and the right filters make all the difference. Here’s what’s commonly used:
Crafted from polyester or cotton, pleated filters are a staple in restaurant HVAC systems. Their folded design boosts surface area, letting them trap dust, pollen, and even some grease particles. With MERV ratings of 8 to 13, they’re efficient enough for dining areas without choking airflow. Restaurants love them for their durability—perfect for humid conditions near kitchens—and affordability. A busy café might swap these out monthly to keep air crisp.
Also called bag filters, these feature multiple “pockets” of synthetic or microglass media.
Rated MERV 8-14, they’re built for high dust-holding capacity and low pressure drops, meaning your HVAC runs efficiently even during peak hours.
Pocket filters shine in restaurants with heavy foot traffic—like a downtown hotspot—where dust and odors need constant control.
One of our clients cut energy costs by 15% after switching to Clean-Link’s pocket filters, thanks to better airflow.
These disposable filters are the budget option, rated MERV 1-4. They catch larger debris but falter against fine particles or cooking odors.
While rare in modern restaurants, you might spot them in smaller, low-budget setups. They’re a starting point, but not a long-term fix for serious air quality needs.
High-Efficiency Particulate Air (HEPA) filters snag 99.97% of particles down to 0.3 microns—think bacteria or smoke.
They’re uncommon in standard restaurant HVAC due to high resistance (which strains systems), but you’ll find them in niche cases, like eateries in healthcare facilities.
For most, they’re overkill—pleated or pocket filters handle the job at a lower cost.

Kitchen exhaust systems are a different beast, designed to vent heat, grease, and odors safely outside. The restaurant filters here focus on fire safety and odor control:
Made from stainless steel or aluminum, baffle filters use overlapping vanes to force air through a maze, trapping grease as it cools.
They’re the gold standard in commercial hoods—reusable, fire-resistant, and easy to clean with a degreaser. High-volume kitchens, like those frying up burgers or wings, rely on baffles to keep ducts safe.
They don’t carry a MERV rating (they’re grease-focused), but they’re a must for compliance with fire codes.
These lightweight grids of aluminum or steel catch grease with a fine weave.
They’re less efficient than baffles—better for low-grease setups like bakeries or sandwich shops—but they’re cheap and simple to maintain.
A quick rinse keeps them going, though they clog faster in heavy frying scenarios.
Often paired with baffles or mesh, carbon filters tackle odors and smoke.
Their activated carbon absorbs cooking smells, making them ideal for open-kitchen restaurants where diners sit close to the action.
They’re disposable, swapped out every few months, and add an extra layer of comfort to the dining experience.
Using an electric charge, these filters attract grease, smoke, and dust to collector plates.
They’re reusable (just wash them) and highly efficient, gaining traction in high-smoke kitchens like BBQ joints.
Pricier upfront, they save money over time—perfect for restaurants prioritizing sustainability.
Choosing the right restaurant filters depends on your setup. For HVAC systems, consider:
For exhaust systems:
