Exhaust charcoal filter: design, function and replacement technology

Let’s find out what work the filter does, how to choose the right replacement element and how to install it. The above information will be useful for those who are just considering the purchase of a recirculation type hood and those who are already using such a unit.

How to install a new replacement unit

The most important recommendation when installing a new or an old cassette is to read the manufacturer’s instructions carefully. It specifies the procedure and some important nuances that apply to specific models.

For example, a simple charcoal cartridge installed the wrong way round will not work properly, and instead of clean air you get a waste of energy.

Instructions are often presented in the form of a plan. a step-by-step description of actions, sometimes accompanied by pictures. Responsible manufacturers supply discs with video-instructions or just give a link to the producer’s site where you can find all the necessary information.

Here are examples of instructions that will help you to install the filters for different models.

How to install and how often to change

Charcoal and grease disposable cleaners need to be replaced quite often to keep the ventilation in the room at the proper level. The frequency of cassette changes depends primarily on which company is listed as the manufacturer.

The simplest extraction units operate with filters, which should be changed at least once every three months. Bosch replacement extractor filters are the most resistant to external influences and allow the cassettes to be changed once a year.

It happens that there is no time or opportunity to find a suitable cleaner for the exhaust unit. Given the rapid rate of obsolescence of today’s technology, it is not surprising that the cassettes for some exhaust units are no longer available. The situation would be absolutely hopeless, if not for two solutions:

Universal filter for kitchen hood. Presents a unique opportunity to use a cassette that is compatible with many other models of extraction devices. The main feature of this product is the same dimensions as other filters. But we have to accept the fact that these models are not the original products of manufacturers. You can make a filter for the hood with your own hands. But the limitation of freedom of action in this case is the very design of the purifier, as well as its type. Thus, a homemade product can only be created on the basis of a carbon core. The grease filter must be the same as the one supplied with the hood. If you take a closer look at the body of the charcoal cleaner, in some models you will see a connecting seam. After opening it, the user can replace the spent activated carbon with a new one

It is important to leave the form of the contents unchanged. granular charcoal.

The grease filter for a single-use hood has its own advantages: the ability to adjust the size of the sheet for a particular hood, as well as the patterns that appear on it, which allows you to control the level of contamination of the filter. But reusable metal cleaners are more reliable in operation. Do not be afraid that the process of changing the cassettes is complicated. If you have to find out how to change the filter in the cooker hood, first unplug the appliance from the mains to protect yourself against any embarrassing or inexpert actions. Then the grease cleaner is removed.

After removing the grease trap, the activated charcoal filter cassette can be removed. This action is accompanied by a “click” sound. The same sound should be heard when inserting the new cassette. As you can see, the principle of filter replacement is extremely simple, so when choosing a model of exhaust unit, the argument about the complexity of the process and the high cost of replacement filter cassettes is irrelevant. To try to prolong the life of the cleaner, leave the hood on for a short period of time after you have finished using it. It allows you to remove excess moisture from the charcoal filter core.

Suggestions for replacement

Combination and disposable products can not be restored by washing or drying. A contaminated component should be changed when certain signs are detected. First of all, it is a change in the color of the indicator mark. The same can be said about the filter strip, which usually takes on a red tint. It is applied by the manufacturer. Also a sign that indicates the need for replacement appears to be a decrease in draft.

At the same time the fan noise increases. After all, you have to buy new filters if the cartridge has reached the end of its service life. Some brands have special sensors for differential pressure. They emit special signals as soon as the charcoal cassette or filter cloth gets dirty. Attempts to wash the filter will not give any result.

It is impossible to remove the absorbed grease from the fibers. The synthetic filler will clog again after washing, and this will happen much faster than in the case of a new product.

At first it is necessary to buy elements for cleaning the air for a certain hood. In this regard, you should give preference to parts made by the same brand as the appliances. Otherwise it does not make a great deal of difference. If it is not possible to find an appropriately sized element, a universal grease filter can be purchased. It is suitable for use on most models of hoods.

Instructions for changing

  • The color of the indicator mark or the inscription on the grease fine filter, applied by the manufacturer (usually becomes red), has changed;
  • The draft significantly decreased, the noise of the fan noticeably intensified;
  • the lifetime of the carbon cartridge has expired;
  • Some brands of hoods are equipped with differential pressure sensors, which signal the complete clogging of the filter cloth or carbon cassette.

To remove the outer grease insert, simply unlock the 2 latches mounted on the edges (some models use a single latch)

Attempts to wash a clogged disposable filter, of course, have been made by many users. The result is negative, it is unreal to remove the absorbed fat from the fibers. Laundered synthetic filler rather quickly clogs again.

First you need to buy an air cleaning element for a particular hood. It is better to give preference to the original filters of the same brand as your appliances. In other cases the manufacturer does not play a major role. If you are unable to find a product of the size required, use a universal grease filter that fits most hoods.

Types of grease filters

There are three types of kitchen hoods: flow-through, recirculation and combination hoods. Depending on the type of appliance that catches fumes above the stove, it has a grease or grease charcoal filter element.

A single filter is sufficient for the proper operation of a flow hood; the grease filter takes the “first hit”, trapping the grease particles and preventing them from penetrating the cabinet.

The intake air in a flow-through hood passes through the grease trap and is then ducted to a ventilation system or passed through a gravity filter and returned to the room clean.

FYI. The grease trap requires periodic cleaning. The sticky residue layer is easy to remove and wash.

Grease traps can be disposable or reusable:

  • The disposable grease trap grid for kitchen hoods is used in cheap extraction units once and for all, until it gets completely fouled. It is made of synthetic material (synthetic, acrylic, fleece) and looks like a small mat. When it gets dirty it is replaced with a new one. Washing is not an option in such cases: after water procedures the grease trap’s effectiveness is reduced to almost nothing.
  • Reusable grease traps have no expiration date. This element is a kind of grid made of aluminum, stainless steel or galvanized steel. Passing through such a filter element, the contaminated air is cleaned of greasy particles, leaving them on the mesh. It can be cleaned very easily with detergents.

Exhaust grease traps vary in size, shape, materials and efficiency. There are metal filters with different numbers of mesh layers.

Grease traps made of synthetic and organic fibres

Filter elements of the disposable category are made of polyester, acrylic, synthetic or fleece with reinforcing adhesive. Mostly all fiber grease traps are disposable and the cheapest.

For your information. There are reusable models of acrylic grease traps. Once dirty, they can be washed and reused. But sooner or later they wear out. After each wash their efficiency gradually decreases. So they can not be called full-fledged filters of multiple use.

It is not recommended to prolong the life of disposable grease traps with different types of cleaning, because cheap products are not provided for this purpose. Washing will damage the fibre structure, making it impossible to clean the air properly and increasing the chance of premature wear and tear.

Metal grease filters

The metal cassette supplied with the extraction unit is used throughout the life of the hood. In fact, such an element is a frame with several thin mesh sheets of steel, foil or aluminum, which are responsible for the primary purification of air.

All cells of the filter cassette are turned at an angle for efficient operation of the filter. The more layers of mesh in the filter frame, the more often the direction of air entering the hood is reversed. Its streams are better cleaned of dirt, grease and combustion products.

Materials of manufacture of the reusable filter:

In the case of foil, several layers of material are used to produce the filter element. To increase the productivity of the grease trap, peorization is used: holes in the material make the filter more efficient. The reusable foil element cleans the air but has a shorter shelf life. They are also less durable than other materials.

Steel grease traps last as long as the hood itself, if not longer. Products made of stainless steel or galvanized steel are durable and safe, cope with the primary air purification and are not prone to corrosion.

Attention! Improper maintenance of the steel grease trap will result in rusting.

The key disadvantage of the steel grease trap element. high cost. They are therefore suitable for use in medium- and premium ranges of cooker hoods.

The aluminium hood filter is efficient, durable and long-lasting. Anodizing is used in the manufacture of some models, so grease traps do not oxidize. The drawback of the aluminum element is the high price, especially for non-oxidizing models.

For ease of maintenance, manufacturers divide one cassette into 2-3 smaller ones. Smaller elements are easier to remove and easier to clean.

Standard filter sizes

Reusable grease filters are durable and can be used throughout the life of the hood. The dimensions of the air-cleaning elements are listed in the machine’s data sheet. If the hood is equipped with non-standard removable elements, you will have to order new ones from the manufacturer.

In the case of the disposable grease trap, the size issue is solved simply. If you cannot find an item of suitable length and width on sale, you can buy a grease trap of a larger size and cut off the excess.
