Range Hood Filter Replacement

Keeping your kitchen clean and odor-free starts with maintaining your range hood. One of the most important aspects of this maintenance is range hood filter replacement. Filters trap grease, smoke, odors, and harmful particles, preventing them from spreading throughout your home. Understanding the types of filters and how to replace them ensures your range hood operates efficiently, and your kitchen stays fresh. 

Types of Range Hood Filters

Range hoods typically come with three main types of filters:

1. Grease Filters

Grease filters trap oil and grease particles produced during cooking. Most modern hoods use metal mesh filters made from aluminum or stainless steel, which are durable and reusable. Some premium models use baffle filters, which allow air to pass while efficiently trapping grease.

2. Charcoal (Carbon) Filters

Charcoal filters remove odors and smoke, especially in ductless or recirculating range hoods. These filters are made from activated carbon and cannot be washed, so they need

 regular replacement. Carbon filters come in different shapes, and each has its own installation method:

• Square Mesh Filters: These are the most common. They usually slide into a slot behind the grease filter. Some models have clips or tabs to hold the filter in place.
• Round Filters: Often used in smaller hoods or specialty models, these circular filters typically twist and lock into the mounting bracket.
• Solid Block Filters (Large Rectangular): These filters are a single block of activated carbon, usually designed for high-capacity hoods. They may require screws or a dedicated housing tray for secure installation.

 

3. Plasma⁺ or Advanced Purification Filters

Some high-end hoods use Plasma⁺, UV, or ionization filters to eliminate bacteria, germs, and fine smoke particles. These filters often last longer than standard carbon filters but still require periodic replacement according to the manufacturer’s instructions.

Range Hood Filter Sizes

Range hood filters come in various sizes to fit different models:

Grease Filters: Typically 10–20 inches wide and 12–18 inches long, depending on the hood size.

• Square Carbon Filters: Usually 8×8 inches to 12×12 inches.
• Round Carbon Filters: Common diameters are 6–8 inches.
• Solid Block Carbon Filters: Often 10–14 inches wide and 5–8 inches thick, designed for high-capacity hoods.

Sizes can vary by brand, so always check your hood’s manual before buying replacements.

Range Hood Filter Replacement

Replacing your range hood filters is essential to maintain proper airflow and keep your kitchen fresh. The replacement method varies depending on the type and shape of the filter. Here’s a detailed guide for different types of filters:

1. Round Carbon Filters

Round filters are commonly used in smaller or specialty ductless hoods. These filters usually twist and lock into place.

Steps:

• Turn off the range hood and remove the grease filter if applicable.
• Locate the round carbon filter in its housing.
• Twist the filter counterclockwise to unlock and remove it.
• Insert the new round filter and twist clockwise until it locks securely.
• Replace the grease filter if it was removed.

 

2. Square Carbon Filters

Square carbon filters are often small, lightweight panels that slide directly into a slot behind the grease filter.

Steps:

• Turn off the hood and remove the grease filter.
• Slide the old square carbon filter out of its slot or release the clips holding it.
• Slide the new square filter into the same slot until it fits snugly.
• Reinstall the grease filter.

 

3. Solid Block Carbon Filters (Large Rectangular)

Solid block filters are larger, high-capacity filters designed for powerful hoods. They are usually inserted as a single unit into a housing tray.

Steps:

• Power off the range hood.
• Open the filter housing tray, sometimes secured with screws.
• Remove the old block filter.
• Place the new solid block filter into the tray, making sure it sits evenly and securely.
• Close the housing tray and reattach any screws if necessary.

Tip: Always check your range hood’s manual for the recommended replacement frequency—usually every 3–6 months for carbon filters, depending on usage. Regular replacement ensures your hood removes smoke, grease, and odors effectively.

 

How to Clean a Range Hood Filter 

• Carbon (Charcoal) Filters: Cannot be cleaned. Simply replace with a new filter when it becomes saturated, usually every 3–6 months.
• Aluminum or Stainless Steel Baffle/Mesh Filters: Can be cleaned and reused.

Cleaning Steps:

• Turn off the range hood and remove the filter.
• Fill a sink or basin with hot water and a few drops of dish soap. Add a little baking soda for tough grease.
• Soak the filter for 10–15 minutes to loosen grease and debris.
• Use a soft brush or sponge to scrub away remaining grease.
• Rinse thoroughly with warm water.
• Let the filter air dry completely before reinstalling.
• Tip: Some metal filters are dishwasher-safe, but always check the manufacturer’s instructions first.

How to Clean a Greasy Range Hood Filter

Keeping your range hood filter clean not only improves airflow but also prevents lingering odors and fire hazards. Here’s how to handle it:

Daily / Regular Maintenance Tips

• Wipe down the exterior of your range hood after cooking to prevent grease buildup.
• Rinse or lightly wash metal filters every 2–4 weeks if you cook frequently.
• Avoid letting grease accumulate for months, as heavy buildup makes cleaning much harder.

Cleaning a Heavily Greased Filter

For filters with stubborn, caked-on grease, follow these steps:

• Remove the Filter: Turn off the hood and carefully remove the filter.
• Prepare a Soak: Fill a sink or large basin with hot water, add a few drops of dish soap, and 2–3 tablespoons of baking soda.
• Soak the Filter: Submerge the greasy filter in the solution for 10–15 minutes to loosen tough grease.
• Scrub Gently: Use a soft brush, sponge, or cloth to scrub away remaining grease. Avoid abrasive tools that could damage the metal.
• Rinse Thoroughly: Rinse with hot water to remove soap and grease residues.
• Dry Completely: Let the filter air dry fully before reinstalling it into the range hood.

Extra Tip: Some metal filters are dishwasher-safe, which makes cleaning easier. Always check the manufacturer’s instructions before using a dishwasher.

This routine keeps your range hood operating efficiently and extends the life of your filter.
