1. Clean or replace filters as necessary
By cleaning or replacing your range hood's filters monthly (or as needed), you can help extend its lifespan and prevent any potential issues that may affect its performance. Whether you need to clean or replace the filters will depend on the type of range hood you have, especially if it's a ducted or recirculating model. 

Range Hood Filter
Most ducted range hoods feature a mesh filter that captures grease and prevents excessive contamination of the outdoor air being exhausted. Mesh filters do not need to be replaced but should be cleaned monthly to prevent buildup.

Here are the steps for cleaning your range hood filter:
Remove the Filter: Most range hood filters can be easily removed by pressing or pulling on tabs or latches. Refer to the manufacturer's instructions for your specific model.

Soak: Fill a sink or bucket with hot water and add a degreaser or neutral detergent. Submerge the filter in the water for 10-15 minutes.
Scrub: After soaking, scrub the filter with a soft brush or sponge, paying special attention to areas with heavy grease and dirt buildup. Use gentle motions and avoid abrasive materials that could damage the filter.
Rinse: Thoroughly rinse the filter with hot water to remove any remaining grease and detergent. Ensure all soap residue is removed.
Dry: Shake off excess water and lay the filter on a towel overnight to dry completely before reinstalling it on the range hood.

Recirculating Filter

If your range hood is a non-ducted model that recirculates air (also known as a recirculating range hood), it likely has a replaceable charcoal filter. This charcoal filter needs to be discarded and replaced monthly, or whenever you notice odors or reduced airflow in your kitchen.

The recirculating range hood filter cleans the air before pushing it back into your home, which means it accumulates buildup faster than ducted filters. Please follow the user manual of your range hood to remove and replace dirty filters. Most disposable filters can be purchased online from the manufacturer or at local hardware stores.

2. Cleaning the Exterior of Your Range Hood
It is crucial to wipe down the exterior of your range hood weekly to maintain its appearance and functionality. Over time, grease, smoke, and dust can build up on the surface of the range hood, making it look dirty and dull. Wiping down the exterior can remove these accumulations, helping restore the range hood's original look and preventing any damage to the surface.

Regularly cleaning the exterior of your range hood also helps prevent the buildup of grease and other debris, ensuring that the ventilation system
 operates properly and keeping the air in your kitchen clean and healthy.

To properly clean the exterior of your range hood, follow these steps:

Unplug the Range Hood: Unplug the range hood to avoid any risk of electrical shock.
Prepare the Cleaning Solution:
Mix a small amount of mild dishwashing liquid or non-abrasive cleaner with warm water in a bowl.

Wipe Down the Exterior: Dip a sponge into the cleaning solution, wring out excess water, and gently wipe down the exterior of the range hood, starting from the top and working downwards.
Clean Knobs and Buttons: Use a damp cloth or cotton swab to clean knobs, buttons, and other hard-to-reach areas.

Rinse with Water: Wipe away any soap residue with a clean, damp cloth. Frequently rinse the cloth in clean water to avoid spreading dirt.

Dry the Exterior: Use a dry cloth or paper towel to wipe away any excess moisture to prevent streaks or watermarks.

Polish (Optional): Depending on the surface finish of your range hood, apply a small amount of stainless steel polish to a clean cloth to achieve a shine.




3. Inspecting the Fan Blades
It's essential to inspect the fan blades of your range hood approximately every six months to ensure they are functioning properly. The fan blades play a crucial role in the performance of your range hood, as they are responsible for drawing in air and removing smoke, grease, and other particles from your kitchen. If the fan blades are dirty or damaged, it can compromise the effectiveness of your range hood.

Depending on the design of your range hood, you may need to remove the filter or cover to access the fan. Once you've unplugged the range hood and removed any hardware, check the fan for buildup or damage. Use a microfiber cloth to wipe away dust or grease on the fan blades, but avoid using any liquid cleaners that could damage the internal electrical system of the range hood.

4. Inspecting Ventilation Ducts
If you own a ducted (or vented) range hood, it's crucial to inspect the ventilation ducts at least once a year to ensure they are clean and functioning properly. The ventilation ducts play a vital role in the performance of your range hood, as they are responsible for carrying air and contaminants out of the kitchen and discharging them outdoors.

While filters can remove some contaminants from the incoming air, over time, grease and dust can still accumulate within the ventilation ducts. Since ventilation ducts are exposed to the outdoors, there's also a risk of pollen or other external debris entering the ducts.

If your ventilation ducts are installed in the wall, you can easily access them by unscrewing the vent cover (refer to the instructions in your user manual based on your model). Use a flashlight to inspect the inside of the ducts for any signs of damage or debris, including cracks, holes, dust, or grease. To remove buildup and improve the functionality of the ventilation ducts, use a cloth or vacuum cleaner hose to clean hard-to-reach areas.

5. Seeking Professional Services as Needed
In general, it is recommended to have your range hood professionally serviced at least once every 1-2 years. The exact frequency of professional maintenance for your range hood depends on several factors, such as the frequency of your cooking, the types of food you prepare, and the type of range hood you own.

To arrange for professional service for your range hood, follow these steps:

Check Your Warranty: If your range hood is still under warranty, review the terms and conditions to determine if repairs are covered.

Contact the Manufacturer: If your range hood is no longer under warranty, contact the manufacturer to inquire about their repair services or if they can recommend qualified technicians in your area.

Search for Local Appliance Repair Services: Conduct an online search for appliance repair services in your area that specialize in range hood repair and maintenance. Be sure to check reviews and ratings to hire a reliable and experienced technician.

Obtain Quotes: Contact several technicians to obtain quotes for the services you need. Compare prices and services to find the best option for you.

In conclusion, regular inspection, cleaning, and maintenance of your range hood are essential components of keeping your kitchen environment clean and healthy. By ensuring that your range hood operates efficiently, you can enjoy a safer, more comfortable cooking experience and protect the health of your family and yourself.

Is my range hood the right size?
To determine the appropriate size of range hood for your needs, consider the dimensions of your stove or cooktop, as well as the size of your kitchen. If you notice that your range hood is not operating optimally even after maintenance, it might be because the previous owner or landlord installed the wrong size.

Here are some guidelines to help you ascertain if your range hood is the right size:

Measure the stove or cooktop: Measure the width of your stove or cooktop to determine the minimum size of range hood you require. Generally, the width of the range hood should be at least equal to, and preferably a few inches wider than, the width of your stove or cooktop.

Consider the kitchen size: The size of your kitchen will also play a role in determining the appropriate size of range hood. For instance, if you have a smaller kitchen, you may need a less powerful range hood, whereas a larger kitchen may require one that can handle higher volumes of air.

Determine the appropriate CFM rating: CFM (cubic feet per minute) is the standard for measuring the amount of air a range hood can draw in. Typically, the CFM rating of your range hood should be at least half the size of your kitchen area. For example, if your kitchen is 200 square feet, you would need a range hood with a CFM rating of at least 100.

Check the manufacturer's guidelines: The manufacturer's guidelines for your range hood should provide information on the dimensions and CFM rating for specific models. Refer to these guidelines to ensure that your range hood is the right size for your kitchen.


In summary, a properly sized range hood should efficiently capture and remove smoke, grease, and other contaminants from your kitchen.
