How to Clean Filter Screen of Range Hood: 5 Self-made Methods

How to Clean Filter Screen of Range Hood: 5 Self-made Methods

Five Reasons for Cleaning the Filter of Range Hood

Even if this doesn't seem to be the best way to kill time, you still need to make sure your range hood filter is well maintained. Top manufacturers such as Braun recommend that you clean the filter at least once a month.

If you are like every ordinary homeowner, it is definitely a big clean-up. Most people have not cleaned the filter for many years, and some have not even cleaned it for ten years. However, as a self-proclaimed expert on range hood, I must support what my brothers told you. The filter must be cleaned continuously for the following reasons:

1. The power efficiency is improved.

2. The service life of the blower is longer.

3. Effectively remove grease and smoke.

4. Easier to clean.

5. Safety

Regular cleaning makes things simple.

Can all filters be cleaned?

There are basically three types of filters on most range hoods:

Fabric grease filter

Metal grease filter

Charcoal filter

As the name implies, the only purpose of the grease filter is to filter out oil smoke and grease. They appear in all range hoods and are different from some models in the past.

Fabric grease filters work by absorbing smoke and grease (much like sponges) and cannot be cleaned, but need to be replaced.

Metal grease filters can and must be cleaned frequently. They are usually aluminum or in some cases stainless steel. They can be screen filters or baffle filters, which can usually be seen at the bottom of the range hood.

Charcoal filters only appear in ductless models because their main purpose is to eliminate odors and smoke. If you want to circulate the air back to the kitchen, this is only a necessary step. These filters cannot and cannot be cleaned. On the contrary, they need to be changed every three to four months, depending on the frequency and type of dishes you prepare.

How to Clean Range Hood Filter in 7 Simple Steps

This may seem like a long process, but depending on how dirty your range hood filter is and the method you choose to follow, the total time may be as high as one hour, while the actual cleaning time will be less than 15 minutes.

1. Remove the metal grease filter

2. Place the filter in the cauldron/sink

3. Prepare cleaning solution

4. Immerse the filter into the solution

It is easy to remove grease with a brush.

6. Let them dry

7. Insert them back into the range hood.


Separate the filter to be cleaned

This will vary depending on your model. However, in all models, the filter is easy to disassemble. But before you start fidgeting and trying to find a way to separate it from your hood, be sure to turn off the appliance.

Take a moment to look at the overall setting of the range hood. Is your metal filter clearly visible or mostly hidden? The first step is to make sure you see the filter clearly. Use a screwdriver to remove any protective plastic or metal housing around the bottom of the cover. In 95% of cases, there will be no protective cover.

Once you have a clear understanding of filters, you will want to know how they connect to the rest of the device. You will notice any of the following:

The screws hold them in place and need to be loosened.

T-locks or similar mechanisms hold them in place.

Metal/plastic fasteners requiring lateral rotation.

Easy to operate latch mechanism, you can press the lever and lift it to separate.

Rim support, just push up and rotate to release the filter.

Fortunately, the most difficult type of connection you will encounter is one that combines support and fasteners. I said the only reason why this is difficult is because some types of rotating flaps are placed in such awkward positions that you will find it difficult to put your fingers in the right position. On the contrary, you may need to turn it with a spoon or screwdriver.

Prepare cleaning solution and filter

We will now introduce steps 3 to 5 of the cleaning process. There is no obvious difference between these steps because each of the five methods is independent and some steps may be skipped.

Note: I will use the most effective cleaning method to achieve the most ineffective. This is done to save reading time, and you will only continue to use another method if some supplies are out of stock and/or you prefer another method because of simplicity.


Method 1: Use dishwasher cleaner

You will use dishwashing detergent to finish this work, not dishwashing soap or grease remover.

1. Wet the filter with a blower hose or under the faucet (hot water is preferred because it can remove some grease).

2. Place the wet filter in a pan or sink (remain free for the next hour).

3. If you want to clean the filter thoroughly, please apply a large amount of dishwasher detergent around the filter, including the metal edges. Don't let any surface stand still.

4. Let the filter stand for one hour.

5. Put it in a sink under hot water to wash away detergent and grease.

6. Apply more detergent and brush away a small amount of grease in the corner.

7. For extremely greasy filters, you may need to repeat the process and let it stay for another hour.

Method 2: Use degreasing agent

Compared with the first method, this method involves a lot of scrubbing. It may not be as effective, but the filter is still very clean.

1. Find a pan large enough to hold the grease filter.

2. Fill it with water so that the filter can be completely submerged (do not put the filter in the pan for the time being).

3. Heat the water, but not enough to boil it. Spray a large amount of degreasing agent into the water. If a large amount of grease needs to be removed, about 20 sprays are required.

4. Place the filter and ensure it is submerged. Don't let your bare hands touch this mixture, because it is a little sour.

5. Leave the filter in solution for 30 minutes to 1 hour.

6. Remove the filter with pliers, put it into the water tank, and scrub both sides hard.

Method 3: vinegar and sodium bicarbonate solution

As an alternative to method 2, you can also use vinegar and baking soda to do the job.

1. Find a jar large enough to fill the filter with water.

Boil the water.

3. After boiling, add 3 tablespoons vinegar and 2 tablespoons baking soda to the solution in turn. Slowly add baking soda, not all at once.

4. Place the filter and let it stay for 30 minutes to 1 hour.

5. Remove the filter with pliers, put it into the water tank and scrub both sides.

Method 4: Hot soapy water+ammonia water

If you always follow your cleaning schedule and clean every other month, this simple method is sufficient only with soapy water and ammonia (not always necessary).

1. Block the kitchen sink and add water+dishwashing soap. You may also want to add some ammonia to make work easier.

2. Mix the solution and put it into the filter.

3. Scrub the filter with a brush.

Method 5: Place in dishwasher

Most modern range hoods are equipped with dishwasher-friendly aluminum or stainless steel grease filters. You need to check the product specifications to determine whether the filter is suitable for the dishwasher, or you can review the product comments or contact customer support.

If your filter is dishwasher friendly, you should make sure to clean it every other month. Because, if you insist on doing this, you don't have to worry about scrubbing and using special solutions to clean them.

However, if you do not clean them regularly, your filter may have accumulated a lot of grease and dirt. In this case, just putting them in the dishwasher will have no effect. Instead, you must follow one of the first three methods explained above.

Air drying and reattachment

Since the filter is made of metal, I do not recommend the use of a hair dryer, as this will lead to electric shock under unfortunate circumstances. Therefore, the best thing you can do is to let them dry in time. Before you put them back in place, make sure they are completely dry, because you don't want the wires of the range hood to get wet.

Dirty range hoods can be dangerous.

Dirty range hoods will not only damage the range hoods, increase electricity bills, but also endanger health and fire.

Health hazards

The dirty range hood is greasy, sticky and warm. This is an environment where some pathogens (bacteria, etc.) breed. In addition, fine food particles are carried along with the smoke and deposited on the filter, which is helpful for culturing bacteria.

Fire risk

Oil and grease deposited on your range hood above the stove is a potential fire hazard waiting to happen. It is not common to cause a fire in this way, but in some cases, the uncontrolled flame on the stove rises and ignites the residue on the filter of the range hood.

Clean the area around the filter

Some parts of the range hood immediately above the stove and around the grease filter will definitely have grease deposits. These areas can be easily cleaned with mild degreasing agent.

All you need to do is use your napkin, spray some detergent and wipe it off. Be sure to read the instructions before spraying, as some of them are concentrated and need to be mixed with water before use.
