A well-maintained range hood ensures your kitchen remains fresh, with clean air and optimal performance. Regular cleaning of the filters, light bulb replacements, and basic troubleshooting are essential tasks that can prolong the life of your range hood and keep it functioning like new. This guide will walk you through the key steps of maintaining your range hood, from cleaning the filters to replacing light bulbs and addressing common performance issues.

How to Clean Baffle vs. Mesh vs. Charcoal Filters
Filters are at the heart of your range hood's functionality. They capture grease, smoke, and other particles that are released during cooking. The type of filter in your range hood will determine how you clean it. The three most common types of filters are baffle, mesh, and charcoal. Each requires a slightly different approach to cleaning.
Baffle Filters
Baffle filters are typically made from stainless steel and feature angled plates designed to trap grease and oil. These filters are durable and highly effective, making them a popular choice in high-performance range hoods. They are especially favored for their efficiency in capturing large particles, and their sturdy design makes them long-lasting.
How to Clean Baffle Filters:
- Frequency: Clean every 1 to 3 months, depending on how often you use your range hood.
- Cleaning Method: Soak the baffle filter in warm, soapy water or use a grease-cutting degreaser for tougher grease buildup. Many baffle filters are also dishwasher-safe, offering a convenient cleaning option. For example, ROBAM range hood's baffle filters are designed to be easily cleaned in the dishwasher, making maintenance quick and simple.
- Tip: Use a non-abrasive sponge or brush to avoid scratching the stainless steel. If hand-washing, a soft brush will help to remove stubborn grease without damaging the surface.

Mesh Filters
Mesh filters are made of a fine metal mesh that traps smaller grease particles. They are commonly found in more affordable range hoods and need regular cleaning to maintain their efficiency. Though not as durable as baffle filters, mesh filters still offer decent grease-capturing performance.
How to Clean Mesh Filters:
- Frequency: Clean every 1 to 2 months.
- Cleaning Method: Soak the mesh filter in warm, soapy water, or simply place it in the dishwasher for a thorough clean.
- Tip: Ensure the filter is completely dry before reinserting it into the range hood to prevent moisture buildup.
Charcoal Filters
Charcoal filters are used in ductless or recirculating range hoods. Unlike the other types of filters, they cannot be washed. Charcoal filters are designed to absorb odors and trap fine particles, but over time, their effectiveness diminishes. They need to be replaced every 3 to 6 months, depending on usage.
When to Replace Charcoal Filters:
- Frequency: Replace every 3 to 6 months or when you notice a decrease in air quality or suction power.
- Tip: Make sure to always use compatible charcoal filters recommended by your range hood manufacturer for optimal performance.
Step-by-Step Deep Cleaning Guide for Your Range Hood
A deep cleaning is essential to keep your range hood performing at its best. Follow these steps to ensure it works like new.
What You’ll Need:
- Dishwasher (if applicable)
- Dish soap, baking soda, white vinegar
- Microfiber cloth & soft brush
- Screwdriver (for older models)
Step 1: Turn Off Power & Let It Cool
Before cleaning, ensure the range hood is unplugged or turned off at the circuit breaker. Allow it to cool down completely to avoid any burns or accidents.
Step 2: Remove the Filters
Carefully remove the grease filters. Depending on your model, filters can either slide out or be unclipped with small tabs or screws.
Step 3: The Easiest Way – Put Them in the Dishwasher
The most convenient way to clean mesh filters and baffle filters is by placing them in the dishwasher. Many modern filters are dishwasher-safe. For best results, place them on the bottom rack with the opening facing down. Choose a heavy-duty cycle or pots and pans cycle to clean thoroughly.
Tip: If your filters are stainless steel, they should come out looking shiny and clean. Just let them air-dry before reinserting.
Step 4: No Dishwasher? 15-Minute Manual Method
If you don’t have a dishwasher, you can still clean your filters manually. Here's how:
- Boil a large pot of water.
- Add ¼ cup baking soda and a small amount of dish soap to the water.
- Place the filters into the boiling water and let them soak for 10-15 minutes.
- After soaking, scrub lightly with a brush if necessary, then rinse and dry completely.
Step 5: Clean the Hood Body
Once the filters are clean, move on to the body of the range hood. Spray the interior with a 50/50 mixture of white vinegar and water or use a degreaser. Let it sit for about 5 minutes before wiping it down with a microfiber cloth. For tough corners or buttons, use a soft toothbrush.
For a final touch, polish the stainless steel surface with a small amount of olive oil on a dry cloth to restore its shine.
Step 6: Replace Charcoal Filters (If Applicable)
If your range hood is ductless, make sure to replace the charcoal filter. These filters cannot be cleaned, so they need to be swapped out every few months. This ensures that your hood continues to filter out odors effectively.
Step 7: Reinstall Filters and Test
Once the filters are dry, reinstall them in their proper places. Turn the power back on and run the fan for about 30 seconds to ensure everything is working properly. Your range hood should now be as good as new, with improved performance.
