Do I need a range hood filter?

Yes, your range hood will not work without a filter. A range hood with good filters will greatly enhance your interior air quality. 

A good filter can also protect you from other indoor air pollutants, such as paint and strong home cleaning products. Don’t overlook the importance of interior air quality. According to the EPA, Americans spend almost 90 percent of their time indoors, where some contaminants are five times higher than outdoors.

What are the different types of range hood filters?

Range hood filters come in a variety of shapes and sizes, including:

  • Baffle filters
  • Aluminum mesh filters
  • Carbon
  • Wool

Baffle filters

Stainless steel baffle filters are the most efficient vent filters on the market. They’re the best for capturing oil, grease, and other impurities from the air in your kitchen. 

These grease filters are made with three-sided baffles that maximize airflow and filter efficiency. When air hits the top baffles, it sharply changes direction, collecting any undesired pollutants on the filter’s bottom baffles. 

Stainless steel baffle filters are a terrific solution due to their innovative design. Baffle filters are standard on most ducted range hoods. If you bought a range hood in the last five years, chances are it came with its own set of baffle filters.

Mesh filters

Mesh Filters are often made of aluminum and stainless steel. You may find them with a honeycomb pattern. Filters made of stainless steel will last longer and filter grease more effectively than filters made of aluminum. 

Some mesh filters include a grease trap to prevent grease and oil from building up too quickly. To catch infections more efficiently, some range hoods have a plastic grease trap inside the blower.

Carbon filters 

Ducted hoods typically use baffle or mesh filters. However, most ductless or recirculating hoods utilize carbon (sometimes called charcoal) filters. The air that is pulled from the stovetop is recirculated back into the kitchen by recirculating hoods.

They are inexpensive, lightweight, and easy to replace. Carbon filters are not washable and always need to be replaced. 

A ducted range hood may be converted into a ductless hood with a recirculating kit, usually sold separately. These kits use mesh or carbon filters to filter the air.

Wool filters

Some people utilize disposable wool filters. These filters are not very common. These filters take only seconds to install. They don’t need to be cleaned or maintained; they may be thrown out and replaced as they get soiled. Disposable hood filters are made of wool and are fully biodegradable. They’re employed in commercial kitchens all around the world. They also meet the National Fire Protection Association’s safety guidelines when utilized appropriately.

What is the best filter?

Stainless steel baffle filters are the most efficient and cost-effective option. They are dishwasher-safe and durable. Baffle filters are the best solution if you do a lot of cooking or enjoy fatty or Asian cuisine. Baffle filters are also a good deal because they can be cleaned in the dishwasher and don’t need to be replaced often. 

If baffle filters are unavailable for your model, mesh filters are a great second choice. Mesh filters are a good option for less frequent chefs. However, the ideal range hood filter is determined by your cooking habits and the hood type.

How to choose the right range hood filter?

Choosing the right filter is critical for ensuring proper ventilation and functionality. The size of your range hood filter will vary by range hood type and model. The narrower your hood is, the smaller your filter will be, and the fewer filters you’ll need.

Align the baffles vertically and use a tape measure to determine the length of your range hood filter. The width of the filter is then determined by measuring the other two sides of the filter. When in doubt, consult your range hood manual or contact the manufacturer. They will guide you in the right direction.

Frequently asked questions (FAQ)

Do you still have questions? Below are some of the most commonly asked questions about kitchen ventilation filters.

When should I replace my carbon filters?

How often you need to replace a filter depends on how often you cook and the type of cooking you do. For optimal performance, carbon filters should be replaced every three to four months.

How often should I clean my range hood filter?

To keep your range hood in good condition, it is recommended to clean your filters every one to three months. If you cook frequently or your cooking is spicy or fatty, you may want to clean them more often.

Are carbon filters effective?

Carbon filters are also less efficient than metal filters because they create more resistance for the air to pass through. Carbon filters are a carbon-based substance that collects impurities while also neutralizing grease and odors caused by your cooking. However, If you don’t have the option of ducting your hood to the outside, carbon filters are the way to go.


Baffle, aluminum mesh, and carbon filters are good filters. Choosing the right one depends on how often you cook, your budget, your cooking style, your hood style, and your kitchen ventilation setup. Nevertheless, range hood filters are essential for keeping your kitchen clean and safe.

Now that you know what hood filters are and how they work, it’s time to choose one that suits your needs. Ensure the filter is regularly washed and replaced as required so you can enjoy a safe cooking experience.
