How To Measure Range Hood Filter? Inspiring 2023 Guide

Measuring range hood filters is important because it is an essential component of a kitchen range hood. In cooking, filters trap grease, smoke, and other particles. As a result of dirt and clogs, the filter loses its efficiency over time. Range hood filters need to be cleaned or replaced regularly in order to maintain optimal performance. Cleaning or replacing the filter, however, requires measuring its size correctly. In this article, we will discuss how to measure range hood filter in detail.

How To Measure Range Hood Filter| Disconnect The Range Hood

In the first step of measuring the range hood filter, it is important to turn off the range hood and unplug it from the electrical outlet to prevent any accidents.

Look for the Range Hood Filter

Range hood filters need to be placed in the subsequent step. The location may vary depending on your range hood brand and model. There are typically two types of filters: metal mesh and baffle filters, which are located underneath the range hood. You will find detailed instructions on how to locate the range hood filter in the user manual for the range hood.

Measure the Filter

In order to determine the size of your range hood filter, you need to measure its length, width, and thickness.

  • Measure the filter’s length. From end to end, this is the longest side of the filter.
  • Measure the filter’s width. From end to end, this is the shortest side of the filter.
  • Measure the filter’s thickness. From front to back, this is the depth of the filter.
  • Use a measuring tape to measure all dimensions accurately.

Note the Filter Size

Make a note of the filter size in inches or millimeters after you have taken all the measurements. You can use this information to determine what size replacement filter you will need for your range hood.

Clean or Replace the Filter

Now, you should know the answer “how to measure range hood filter.” As soon as you have measured and noted the size of the filter, you can proceed to clean or replace it.

Types of Range Hood Filter

Following are the filter types that can be helpful in measuring range hood filters:

1-Stainless Steel Baffle Filters

Stainless Steel Baffle Filters

A stainless steel baffle filter is one of the most effective filters on the market. What makes them so effective? 

When your range hood is running, these grease filters feature alternating three-sided baffles that improve airflow and grease filtering. A quick change in direction occurs when air strikes the top baffles, aiding in the collection of undesirable contaminants on the bottom baffles of the filter. Range hoods of all sizes and styles benefit from stainless steel baffle filters due to their unique design. They are the best at capturing grease, dirt, and other contaminants from the air in your kitchen. A stainless steel baffle filter is standard on most ducted range hoods.

2-Stainless Steel Mesh Filters

Stainless Steel Mesh Filters

There are some range hoods that come with stainless steel mesh filters. There are four different Proline models with mesh screen filters: two wall-mounted range hoods and two island-mounted range hoods.

  • Wall hoods: PLFW 520, PLFW 544
  • Island hoods: PLFI 520, PLFI 544
  • The grease traps included with some mesh filters prevent grease from building up too quickly.

In the case of a mesh filter that is flat or level, no grease trap will be included with the hood. To capture unwanted contaminants more effectively, some Proline models feature a plastic grease trap. Stainless steel and aluminum mesh filters are both available. Stainless steel filters are more durable and more effective at removing grease than aluminum filters.

3- Charcoal Filters

Charcoal Filters

Charcoal filters are most common in ductless and recirculating hoods, while stainless steel baffles and stainless steel mesh filters are most common in ducted hoods. In contrast to ducted hoods, which exhaust air outside the house, recirculating hoods circulate air back into the kitchen from the stovetop.

A ducted hood can be converted to a recirculating hood using a recirculating kit. Besides baffles and aluminum filters, the hood will also use charcoal filters. A recirculating kit can be used to convert Proline’s wall-mounted and under-cabinet range hoods to ductless.

How To Choose The Best Range Hood Filter

A good range hood filter keeps your kitchen ventilator running efficiently and maintains clean indoor air. How to pick the right one:

Understand Filter Types:

Grease Filters: 

During cooking, these filters capture grease and oil particles. They’re usually made of aluminum or stainless steel mesh. You can reuse grease filters, but you have to clean them regularly. Soak them in hot, soapy water, scrub gently, rinse well, and let them dry completely before reinstalling.

Charcoal Filters: 

Smoke and odors are trapped by charcoal filters. The granules adsorb and neutralize odorous molecules. Range hoods with ductless or recirculating filters usually have charcoal filters. The charcoal filters don’t last forever and need to be replaced every few months, depending on how often you cook.

Baffle Filters:

Filters with baffles are great for removing grease and are durable. They’re made of multiple layers of metal panels with strategically placed curves and ridges. With these curves and ridges, airflow is redirected, and grease is trapped. Filters with baffles are great for capturing grease and are easy to clean. It’s easy to clean them by hand or in the dishwasher.

Consider Hood Type:

Ducted Hood: 

If Cooking odors and grease are removed from the kitchen by your range hood, which is ducted to the outdoors. The best option here is a baffle or combination filter that filters grease and charcoal. A baffle filter will trap grease, while a charcoal component will get rid of odors.

Ductless Hood: 

Range hoods with charcoal filters do a great job of removing cooking odors. Make sure the filter you choose is compatible with the model of your ductless hood. For optimal performance, keep an eye on the charcoal filter’s condition and replace it when necessary.

Filter Size and Compatibility:

Choosing replacement filters requires accurate measurements. Your range hood’s filter slot or existing filter should be the right size. Because filters come in different sizes, you need to choose one that fits snugly without gaps or protrusions. For filter compatibility recommendations, check your range hood’s manual or contact the manufacturer. Using the right filter size and type ensures proper airflow.

Maintenance and Replacement:

Think about your maintenance preferences and schedule. You don’t have to replace grease filters because they’re reusable. When budgeting for filter maintenance, remember that charcoal filters need to be replaced periodically.

Filter Efficiency:

Choose high-efficiency filters if you cook a lot at high temperatures. A filter that captures grease and smoke particles keeps your kitchen cleaner and reduces grease buildup in your ductwork. Filters with high efficiency are often labeled with their effectiveness percentage.


Depending on the type, brand, and quality of the filter, prices can vary a lot. If you’re tempted to go for the cheapest option, think about the long-term savings. A high-quality filter may extend filter life, improve filtration, and save you money in the long run.

Brand and Quality:

The best filters should be chosen from reputable brands that have a reputation for quality and durability. Using high-quality filters will increase the likelihood that the filters will last longer and have less chance of deteriorating prematurely.

Replacement Schedule:

Depending on your cooking habits, make a regular cleaning or replacement schedule. A monthly grease filter cleaning is a good starting point, but you can adjust it as needed. Typically, charcoal filters need to be replaced every three to six months, but check the manufacturer’s guidelines.

User Reviews:

Users’ reviews and recommendations can give you valuable insight into filter performance, longevity, and overall satisfaction. You can make an informed decision if you read real-life experiences from fellow users.

When you take these factors into account and know the types of filters available, you can choose a range hood filter that ensures effective ventilation, clean indoor air, and a healthier cooking environment.
