Range Hood Filters (Everything You Need to Know)

Range hood filters are an essential component of any kitchen. They help prevent grease fires, trap smoke and protect your home. 

In this article, we will cover you through the different types of range hood filters. By the end, you’ll be able to weigh the advantages and disadvantages of each filter and determine which is best for you based on your preferences, cooking style, and budget.

What are range hood filters?

A range hood filter is an attachment that fits inside your range hood to filter out grease, dust, smoke, and other impurities from the air above your range or stove. 

Stainless steel baffle filters, aluminum mesh filters, and carbon filters are the three most popular types of filters. You may also find wool filters, which can be placed over a mesh filter for added functionality.

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 two to five times higher than outside.

What are the types of range hood filters

Range hood filters come in a variety of shapes and sizes. Below are some of the most common.

  • Baffle filters
  • Aluminum mesh filters
  • Carbon

Baffle filters

Stainless steel baffle filters are some of the most efficient 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 alternating 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, the majority of ductless or recirculating hoods utilize carbon (sometimes called charcoal) filters. Recirculating hoods recirculate the air they extract from the stovetop back into the kitchen.

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 take only seconds to install. They don’t need to be cleaned or maintained, and 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.

Are carbon filters effective?

While exterior ducted range hoods will always be the best solution, carbon filters are a great, effective alternative for those who can not vent to the outside. Carbon filters are also less efficient than metal filters because they create more resistance for the air to pass through.

carbon filters are constructed of a carbon-based substance that collects impurities while also neutralizing grease and odors caused by your cooking. If you don’t have the option of ducting your hood to the outside, carbon filters are the way to go.

What is the best range hood 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 cost-effective as they are dishwasher safe and do not need to be replaced as frequently. 

If baffle filters are not available 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 as well as the hood type.

How to choose the right range hood filter?

Choosing the right filter is critical for ensuring proper ventilation and functionality. Here are some things to consider. 

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. 

How often should I clean my range hood filter?

Many people struggle with keeping them clean or understanding when to replace them and how often to do so. 

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 wish to clean them more often.
