Replacing and Purchasing Hood Filters: A Comprehensive Guide

Modern kitchen range hoods (also known as cooker hoods) play a crucial role in keeping our kitchens free of grease and odors. Central to a range hood’s effectiveness are its filters – typically either metal grease filters or carbon filters. Replacing these hood filters regularly is essential for optimal performance and kitchen safety.

Why Hood Filters Are Important

Hood filters are the unsung heroes of kitchen ventilation. As you cook, especially when frying or sautéing, the range hood’s fan draws up smoke, grease droplets, steam, and odors. The hood filter traps grease and particulates and (in the case of carbon filters) helps eliminate cooking odors from the air.

Modern kitchen range hoods (also known as cooker hoods) play a crucial role in keeping our kitchens free of grease and odors. Central to a range hood’s effectiveness are its filters – typically either metal grease filters or carbon filters. Replacing these hood filters regularly is essential for optimal performance and kitchen safety. In this comprehensive guide, we’ll explore everything you need to know about hood filters, from understanding the types and when to replace them, to how to purchase the right replacements. Our focus will be on metal grease filters (of which there are over 150 types available on OZBA Spare Parts) and carbon filters (around 50 types available). Let’s dive in!

Key Takeaways:

• Metal grease filters trap grease and particles; they are usually washable and reusable, but should be cleaned often and replaced if damaged or overly dirty.

• Carbon (charcoal) filters absorb odors in recirculating (ductless) hoods; they are not washable and must be replaced periodically (generally every 3–6 months for best performancebroan-nutone.combroan-nutone.com).

• Replacing hood filters on time improves ventilation efficiency, prevents grease build-up (a potential fire hazardbroan-nutone.com), and keeps your kitchen smelling fresh.

• When purchasing replacement filters, match the type (grease vs. carbon), size, and model compatibility. OZBA Spare Parts offers a wide range of filters for various brands and models (over 200 hood filter products in total).

• Replacing filters is usually a quick DIY task: metal filters often pop in and out easily, and carbon filters can be swapped in a few simple steps (as shown in videos and steps below).

Why Hood Filters Are Important

Hood filters are the unsung heroes of kitchen ventilation. As you cook, especially when frying or sautéing, the range hood’s fan draws up smoke, grease droplets, steam, and odors. The hood filter is the barrier that traps the grease and particulates and (in the case of carbon filters) helps eliminate cooking odors from the air. By doing so, filters protect the internal parts of your hood (fan, motor, ductwork) from grease build-up and improve the air quality in your homebroan-nutone.com. Regular maintenance of these filters is not just about cleanliness – it’s also about safety and performance. Grease accumulation in filters can become a fire risk and can drastically reduce your hood’s airflow efficiency if not addressedbroan-nutone.com. In short, clean and effective filters mean a cleaner, safer kitchen.

Types of Range Hood Filters

Caption: The three main types of range hood filters: Charcoal filters (left) for odor absorption, aluminum mesh filters (center) for grease trapping, and stainless steel baffle filters (right) for heavy-duty grease removal. Most home kitchens use either mesh grease filters or disposable charcoal filters (or a combination in recirculating hoods).

Range hood filters come in a few different types. The two most common categories – and the focus of this guide – are metal grease filters and carbon filters:

Metal Grease Filters (Aluminum or Stainless Mesh)

Metal grease filters are usually made of aluminum or stainless steel mesh. They are designed to capture grease and food particles from the cooking vapors. These filters often consist of multiple layers of fine metal mesh or expanded aluminum, which present a large surface area for trapping grease. Metal filters are found in almost every range hood – whether your kitchen is vented to the outside or recirculating internally, there will be a metal grease filter at the intake.

Key features of metal filters:

• Durability & Reusability: Metal filters are built to last and are washable. You don’t throw them away when they get dirty (at least not initially); instead, you clean them and put them back. In fact, aluminum filters are unique in that they can be cleaned by the user, a self-maintenance feature not shared by other filter typesbroan-nutone.com.

• Maintenance: It’s recommended to clean metal filters regularly – many manufacturers suggest cleaning them about once a month or whenever you see grease buildup. They can often be cleaned with warm soapy water or run through a dishwasher (check your hood’s manual to be sure it’s dishwasher-safe). Regular cleaning keeps airflow strong and reduces fire risk by preventing excessive grease accumulation.

• Replacement Interval: While metal filters can last a long time, they may eventually need replacement if they become permanently discolored, warped, or the mesh is damaged. There isn’t a fixed timetable for replacing a metal filter – it depends on usage and care. Some experts suggest that if a metal filter is kept clean, it might only need replacing every few years or only if damaged. Always inspect the filter for wear and tear; if the mesh has holes or the frame no longer fits snugly, it’s time to replace it. (We’ll cover how to replace it in a later section.)

• Examples: We carry a wide variety of metal grease filters. For instance, the Whirlpool W10169961A range hood grease filter is a popular model for certain free-standing hoods – a sturdy aluminum filter that fits many Whirlpool models and keeps them running efficiently. Another example is the Bosch 11010157 Hood Grease Filter, a metal filter compatible with select Bosch models, measuring 345x200mm – ideal for maintaining clean airflow in those units. Each model of hood has specific dimensions and fitting for its metal filter, so it’s important to get the right one.

Carbon Filters (Charcoal Filters for Odor Removal)

Carbon filters (also called charcoal filters) are made of activated carbon and are used to neutralize odors and smoke. Unlike metal filters, which capture mainly grease, charcoal filters are all about scrubbing odors from the air. They are used in recirculating range hoods – that is, if your hood does not vent to the outside but instead recirculates the air back into the kitchen after filtering, it will use a carbon filter in addition to the metal grease filter. The air passes through the grease mesh first, then through the carbon filter which absorbs odors and any remaining impurities.

Key features of carbon filters:

• Odor Absorption: Activated carbon has a porous structure that traps odor molecules. This helps remove cooking smells (like frying odors, spices, etc.) before the air returns to your kitchen. If you’ve ever noticed a recirculating hood not completely removing a fishy or spicy aroma, the carbon filter likely needs replacement or is missing.

• Not Washable: Carbon filters cannot be cleaned or washed. When they become saturated with odors and grease, their effectiveness drops and they need to be replaced. Attempting to wash or rinse them will ruin the activated carbon’s structure and won’t restore odor-absorbing ability. This is a major difference from metal filters – carbon filters are disposable.

• Replacement Interval: Most manufacturers recommend replacing carbon filters on a regular schedule. A common guideline is every 3 to 6 months, depending on how often you cookbroan-nutone.com. Heavier cooking (especially frying or strong aromatic cooking) will saturate a carbon filter faster. Some high-end ranges have indicator lights or reminders for filter replacement after a certain number of hours of use. For instance, Broan-NuTone advises that charcoal filters should be replaced at least every six months to ensure they continue to perform efficientlybroan-nutone.com. Bosch’s guidance is even more frequent – about every 3-4 months under normal usagebosch-home.com. In practical terms, check your carbon filter every few months; if you notice it’s grayish, has lost its charcoal odor, or your hood isn’t controlling smells as well as before, it’s time for a new one.

• Usage: Carbon filters are only needed for ductless (recirculating) hoods. If your range hood is vented outside, you might not have a carbon filter at all (just metal filters). In ducted setups, odors are expelled outdoors, so charcoal filters are unnecessary. However, even ducted hoods have metal grease filters – so remember, carbon filters add odor removal but do not replace the grease filter.

• Examples: We stock dozens of carbon filter models. For example, the Elica CFC0140343 Carbon Filter is a round charcoal filter cartridge designed for certain Elica brand cooker hoods (a well-known range hood manufacturer). It contains activated carbon to refresh the air and typically comes in a set of two for a hood. Another example is a Hoover replacement charcoal filter set (16 cm) for Hoover recirculating hoods – these are easy to install snap-in carbon pads that fit into the hood fan. We also carry charcoal filters for brands like Bosch/Siemens (e.g., the Bosch DWA0LK6A carbon filter replacements) and many others. Always get the carbon filter specified for your hood model or an OEM-compatible substitute of the same dimensions.

Internal product links (carbon filters):

• Elica CFC0140343 Carbon Filter – an activated carbon filter cartridge for select Elica range hoods (commonly used in recirculating setups). Sold typically as a set, it effectively absorbs odors to keep your kitchen smelling fresh.

• Hoover Ductless Charcoal Filters (16cm, Set of 2) – example of a universal replacement for certain Hoover (and compatible) recirculating hoods. Easy drop-in installation and restores odor absorption in your hood.

(Note: Some other types of filters exist, such as foam grease filters or paper filters, mostly in older or budget hoods. These serve the same purpose of trapping grease. Foam filters are washable a few times and then need replacing; paper filters are completely disposable once clogged. However, nowadays, aluminum mesh filters and charcoal filters are far more common, especially in newer modelsozbaspareparts.storeozbaspareparts.store. For the scope of this guide, we’ll stick to metal mesh and carbon filters.)

When to Replace Your Hood Filters

Knowing when to replace the filters is key to maintaining performance. Here are some guidelines on replacement frequency and signs that it’s time:

• Metal Grease Filters: These don’t have a set “expiration” but look for signs of wear. Clean your metal filter regularly (e.g. monthly). Over time after many cleanings, the filter may still look greasy or discolored even after washing, or the mesh might start separating. If the filter has any rips or holes, or if it remains noticeably greasy/dirty after cleaning, you should replace it. Even if it looks okay, consider a replacement every couple of years for heavily used hoods, as the mesh can gradually clog in areas you can’t easily scrub. Also, if you accidentally damage or bend the filter during cleaning, get a new one to ensure a proper seal and fit.

• Carbon Filters: Replace on schedule. As mentioned, usually every 3–6 months is recommended for active cooks. At minimum, replace a carbon filter twice a yearbroan-nutone.com. If you do a lot of frying or spicy cooking, every 3 months might be better. A telltale sign is if cooking smells that used to be absorbed are lingering more than before – that indicates your charcoal is saturated and no longer effective. Also, the carbon filter might visibly change color (often darkening) as it gets used; some have an indicator stripe that changes when spent. Always replace after deep cleaning the hood (for example, if you do a seasonal deep clean of your kitchen, put a fresh carbon filter in afterward). Pro tip: Keep a spare carbon filter on hand so you can swap it out on schedule without waiting to order a new one.

• Other Signs It’s Time to Replace:

  • Reduced Airflow: If you notice the hood isn’t pulling air like it used to, first check if the grease filter is clogged. After cleaning the grease filter, if airflow is still weak, a saturated carbon filter could be impeding air (in recirculating models). Replacing the carbon filter can help restore airflow.

  • Visible Damage or Warping: Any cracks in a carbon filter housing or warping of a metal filter are signs for immediate replacement. Filters must fit snugly; damage can create gaps for grease to pass through or air to bypass the filter.

  • Grease Drips: If grease is dripping from the hood or edges of the filter, the metal filter is overloaded with grease. Clean it promptly – if it’s been a long time or it’s very gunked up, you might opt to replace it entirely.

  • Odor Returns: With a recirculating hood, if you start smelling last night’s dinner the next day, your carbon filter is likely past its prime.

In summary, metal filters: clean often, replace when damaged or ineffective. Carbon filters: replace often (3-6 months) as a routine maintenance itembroan-nutone.com.

How to Replace Hood Filters (Step-by-Step)

Replacing hood filters is usually straightforward and does not require any special tools in most cases. Always refer to your hood’s instruction manual for specifics, but here are general step-by-step guides:

Replacing a Metal Grease Filter (Mesh Filter)

Most mesh grease filters are held in place by a latch or spring clip. Here’s a general process:

1. Power and Access: Turn off the range hood (and stove) for safety. You don’t need electrical access in most cases, but ensure the fan is off. If your hood has a light, turning it on can help you see. (Tip: as shown below, turning on the hood light can illuminate what you’re doing.)

   Caption: Before removing the filter, turn on the hood’s light (if available) to better see the clips and any grease. Ensure the hood fan is off and the area is well-lit and safe to work in.

2. Release the Filter: Locate the filter latch or push-button. Most modern hoods have a little finger tab or knob you push or slide to unlock the filter. Push the latch in or slide it as indicated – you’ll feel the filter disengage. Support the filter with your other hand while you do this so it doesn’t fall out suddenly.

   Caption: Press the spring-loaded filter latch to release the grease filter. Most under-cabinet hoods have a tab like this: push or pull it and the filter will pop loose. Be ready to hold the filter as it drops down.

3. Remove the Filter: Tilt the filter downward from the back, then pull it out. It may have to angle out of a slot. Carefully remove the metal filter from the hood. (If there are multiple filters side by side, remove them one at a time in the same way.)

   Caption: Once unlatched, slide the grease filter out from the underside of the hood. Here you can see the filter partly removed – behind it is the blower fan. Take this opportunity to also wipe the inside of the filter housing while the filter is out.

4. Clean or Discard: If you are replacing the filter with a new one, set the old one aside (you can clean it later or dispose of it if it’s beyond use). It’s a good idea to clean the surrounding area while the filter is out – wipe down the edges of the hood opening and any accessible fan surfaces to remove built-up grease. A paper towel or cloth with a degreaser works well for this.

5. Insert New Filter: Take your new metal filter (make sure it’s the correct size and orientation). Angle it into the slot the same way the old one came out. Typically, you insert the front edge in first into a groove, then push the back up. Press until the latch or clip snaps into place, securing the new filter. It should sit firmly with no wobble.

6. Test Fit: Give the new filter a gentle tug to ensure it’s locked in. It shouldn’t pop back out unless you release the latch. Also, turn on the fan briefly to make sure everything sounds normal (no vibration or rattling from a loose filter).

That’s it – your grease filter is replaced! Most can be swapped in a matter of minutes. Remember to reset any filter replacement reminders your hood might have (some hoods have a timer indicator that you can press and hold to reset after cleaning or replacing filters).

For visual learners, here’s a quick video demonstration of replacing (and cleaning) a mesh grease filter, courtesy of Hotpoint:

(Video: Hotpoint Service guide on how to remove, clean, and replace a cooker hood grease filter. Notice how the technician presses the filter clip to pop it out, then washes the filter.)

Replacing a Carbon Filter (Charcoal Filter)

Carbon filters in a hood are usually located behind the grease filter or in the center of the blower. The exact mechanism can vary: some charcoal filters are round discs or cartridges that twist into the blower; others are rectangular pads or frames that clip in. Here’s a general guide:

1. Remove Grease Filters First: In almost all cases, you must take out the metal grease filters to access the carbon filter. So follow the steps above to remove the mesh filters; behind them you will see the blower opening or the area where the carbon filter sits.

2. Locate the Carbon Filter: Many hoods use round carbon filter cartridges that attach directly to the motor or fan. Others might use one or two flat carbon pads that slide in behind the mesh. Inspect your hood – you may see a round plastic disc in the center (that’s the charcoal filter) or slots where a rectangular filter sits. Check your manual for the exact location if unsure.

3. Remove the Old Carbon Filter: For round filters, they often have a twist-lock or simple catch. Typically, you grasp the filter and rotate it about a quarter turn counter-clockwise to unlock, then pull it out. Some have tabs you press to release. For rectangular carbon filters, they might slide out or be held by clips – undo any clips and pull the filter out. The filter could be dirty, so consider wearing gloves or have a trash bag handy to place it in, as it may shed carbon dust or grease.

4. Clean Surroundings: While the carbon filter is out, wipe around the area, as this spot can accumulate fine grease and dust. Ensure the fan blades or housing are relatively clean.

5. Install New Carbon Filter: Take your new carbon filter (make sure it’s the correct model for your hood – shape and size should match the old one). Install it in reverse of removal. For round filters, align the filter’s tabs with the slots on the blower and twist clockwise until it locks in place. It should feel secure and not wobble. For panel filters, slide or clip the new filter into position exactly as the old one was, and re-engage any latches or clips to hold it. It should cover the entire opening without gaps.

6. Reinstall Grease Filters: With the new carbon filter in place, put your metal grease filters back in (as per the previous section). The grease filters will hide the carbon filter from view again.

7. Test: Turn on the hood briefly to ensure there are no unusual noises. You won’t immediately see a difference, but you should notice in subsequent cooking that odors are reduced – a sign your new carbon filter is doing its job.

For a demonstration of how a typical round charcoal filter is replaced, see the video below (by Hotpoint, demonstrating carbon filter replacement in a recirculating hood):

(Video: Hotpoint Service guide showing removal of the metal filters, then twisting off the old round carbon filters and installing new ones in a cooker hood. This process is very similar for many brands.)

As you can see, these are relatively simple maintenance tasks. By regularly replacing your filters, you ensure your hood runs quietly and efficiently. It’s a small effort that makes a big difference in kitchen air quality.
