How to choose a carbon filter for your hood

Exhaust charcoal filter. operation and installation features

As we have already mentioned, the recirculation device cleans the air by using a carbon filter for the hood for this purpose. The principle of operation of such devices is somewhat more complicated than that of devices ensuring removal of exhaust air from the room. In the latter case, the air is simply discharged outside the kitchen through the ventilation shaft.

Such devices have no need to clean the extracted air, but, nevertheless, the motor protection from grease particles is still present in the form of a grease filter. The same element is equipped with hoods with charcoal filter without exhaust air (recirculation).

It turns out that in such devices, in addition to the charcoal filter, there is also a grease filter. The need for such a variety of cleaning elements is explained quite simply: the grease filter is aimed at high-quality purification of air flows from impurities grease particles, which, with a long-term accumulation on the motor will lead over time to its failure. Charcoal filter for the kitchen hood additionally cleans the air from the remaining impurities of grease, odors and other pollutants.

The result is the combined work of several purifying elements, which allows you to return the air into the room as clean as possible. However, the disadvantage of this scheme is the lack of fresh air supply.

But the price range of such devices as a kitchen hood with charcoal filter is very acceptable for any category of consumers. In addition, when replacing the cleaning elements does not have to pay an impressive amount, since their cost is more than affordable.

The comparative cheapness of such cleaners is explained by their design. The core of the filter is made of activated or chemically treated charcoal, which allows it to remove impurities, the volume of which is five times greater than the amount of the coal itself. But this is not all the advantages of such equipment, as in addition to full-size devices, you can also opt for such a model as a recessed hood with a charcoal filter. In this case, overhanging cabinets over the stove will hide the hood device inside. As a result, the kitchen interior is not damaged and the air is purified regularly.

Why do we need them: principle of operation

Coarse filters are also called grease filters. They are a must for any air purifier. This device is designed to purify the air masses that are sent directly to the unit.

First of all the small suspended particles of grease are sifted out. If such a filter is missing, after a few months you would notice that the outer and inner surfaces of the device are covered with an oily liquid with bits of dust.

Manufacturers offer disposable and reusable grease filters. The most practical is the latter type.

choose, carbon, filter, your, hood

Disposable models are made of sintepon, fleece or acrylic. They are installed in the most budgetary hood designs. They are called mats, and are thrown away after a couple of months of work after the surface is completely dirty.

Important! Such single-use grease filters must not be washed, otherwise they will lose their properties.

Reusable” refers to metal filtering that lasts as long as the hood itself. The use of reusable metal construction does not reduce the quality, reliability, durability and safety of the entire unit.

Such devices do not need to be replaced, you only need to remember about hygienic procedures in the form of washing and cleaning the surface. Such a filter is made of stainless steel, galvanized steel or thin aluminum.

Important! If aluminum was used in the manufacture, it is likely to have undergone an anodizing procedure additionally. It protects the device from the oxidation process.

Depending on the model, the metal filter system may have several layers and modules at once. The best durable one is a metal frame made of stainless steel.

Types of grease filters

In addition to the classification on the metal reusable and disposable, there are other types and subspecies of such devices.

Filters can be single or multilayer. Of course, the multilayer filtration system is more expensive. There is also a difference in shape. For example, rectangular, round and square.

The filtration systems also differ in terms of material. Are made of fleece, acrylic, stainless steel, galvanized steel, aluminum and so on.

Reviews of grease filters: pros and cons

They are invaluable for your kitchen. Buyers have long noted a number of advantages that are inherent in these devices.

Before buying it is advisable to get acquainted with the reviews, because each manufacturer uses its own technology to manufacture products from metal.

  • The advantage of the grease trap filter is that it prevents oily liquids from getting into the hood body.
  • The grid prevents dust from the hood from settling on the food.
  • Reusable filters last a long time, do not fail.
  • Panels are easy to remove for hygienic procedures.
  • Partially muffle the sound of the appliance in operation.
  • Some models of hoods are not equipped with a convenient way to remove the panels.
  • If you own metal panels, every few months you need to remove them and clean them thoroughly. However, the procedure is much easier if you have a dishwasher.
  • If you bought an inexpensive model, you might find that it has disposable filters. And they need to be replaced every few months.
  • Some panels are made of such materials from which grease is difficult to clean. By washing it off as well, you can simply leave a mark on the panel.

Instructions for replacing the element

If you are faced with the need to replace the filter, you will probably need a step-by-step guide on how to do it quickly and easily.

Familiarize yourself with the instructions that tell you how to remove the accessories from the hood. If there is no manual or there is no separate section on this subject, then go to the next step.

  • Approach the hood and take a close look at the mounting system. Some panels simply fit into the grooves. Others are attached by pressing a special button. Third panels are simply plugged in.
  • Decided on the method of attachment, try to carefully take out the accessories. Move carefully so as not to damage the filter or hood.
  • After taking the appliance out, place it in the sink. Now you can carry out hygienic procedures that aim to clean the grid.

Types of filters in hoods

There are three types of filters used in modern hoods:

Let’s take a closer look at each type of filtration system.

Grease filter for the hood

A grease filter is a mandatory component of any hood. It traps vapors, grease and all kinds of food spills and prevents them from depositing on the internal walls, the fan and the motor. Without this filter already in 2-3 months all inside of the hood would become greasy, sticky and very dirty, and the motor would most likely burn out in a short time.

The grease filter can be disposable or reusable. It is installed in a flat bottom panel, through which the air intake.

Non-disposable filters for the hood

Disposable hood filters are mostly found in inexpensive models. They are a layer of synthetic material: synthetic, fleece or acrylic. The life of these filters depends on how often you use your stove. On average, it is 1-2 months.

These filters cannot be cleaned. As they get dirty, they must be removed and replaced with new ones. In some models of hoods spare disposable “mats” are included. Otherwise you have to buy them separately, which means you have to pay for them on a regular basis.

But it also has the advantage that you don’t have to spend time and effort cleaning.

Reusable hood filters

The reusable hood filter is a fine mesh metal filter made of galvanized steel, aluminum or stainless steel. Such structures are durable and do not require replacement.

As they get dirty they need to be removed and washed. As a rule, they have special locks for easy removal and fastening.

The best quality are considered grids of stainless steel. They do not oxidize, do not deform. Depending on the specific hood model and size, the reusable grease filter can be a single filter (one piece) or made up of 2 or 3 individual cassettes.

Exhaust charcoal filters

Kitchen hood charcoal filters are built into all recirculation units. Their main task is to clean the air of impurities and odors. Visually, it is a plastic cassette consisting of several cartridges filled with activated carbon.

The air passing through all the charcoal compartments is completely cleaned and comes out fresh and disinfected. The charcoal filter must always be installed after the grease filter. If you do not protect it with a grease-absorbing mesh, it will quickly fall into disrepair, clogged with food sticky particles. The cartridges become soiled with use that they must be replaced. Depending on the manufacturer, they have a service life of 3 to 4 to 6 to 7 months. If users cook on the stove infrequently, the charcoal filter can last even a year.

Carbon cassettes are seldom used in conventional air extraction hoods. But if you wish you can buy such a filter separately and install it in the air exhaust pipe.

If a dirty carbon filter is not changed in time, the airflow will be more difficult to pass through it, which will increase the load on the engine.

Universal filters for a cooker hood

Universal hood filters are a more advanced type of filter that combines a carbon cartridge protected by a grease-absorbing material. Universal cleaning systems are relevant for recirculation hoods, when the most effective air purification is required.

The additional grease-absorbing material layer is also disposable and may require several replacements over the life of the carbon cartridges.

There are also universal filters in which the walls of the cartridges themselves consist of a special material that increases the filtration efficiency.

On average, it lasts between 6 and 12 months, after which it must be replaced.

Which is better: charcoal or grease hood filter

Both varieties provide a similar effect. Whatever type of hood is used, you must install a grease filter in your kitchen. This is due to the fact that in its absence the activated carbon filter element located in the housing will be contaminated faster. The size of the grease filter is larger than that of the charcoal filter. This feature helps to increase the coverage area, which improves the efficiency of the extraction system.

The grease filter is represented by different types:

Anodizing method is used to improve the quality of the filter element. However, such products are installed on expensive hoods. The aluminium filter is the preferred option. They are rugged, durable and not prone to corrosion.

The carbon analogue is inferior to these variants in terms of durability, reliability. These components are often replaced in the hood, the disadvantage is the need to control the life span of the filters. If we compare the different types of products, it is noted that the charcoal version can replace the grease trap as well. The design has two different functions: it removes grease from the air flow and cleans the air of smoke and odors. By comparison, a grease trap will not provide the desired result, t. к. The mesh size of the grid is big enough.

Note that the grease filter can also be disposable, but it has a shorter lifespan compared to its charcoal counterpart. For this reason, they use reusable designs more often. There is also a combination filter for the hood. It contains carbon fibers, but the outside of the product is protected by a synthetic material, while the outer layers retain grease. The contents of the package remove contaminants from the air stream. But the price of such products is high.

Specification

Technical specifications depend on the type of activated charcoal filter. Here are the features of the Folter filter as an example:

  • Capacity: 2500 to 22500 cubic metres per hour.
  • Aerodynamic resistance (initial): 120 Pa (plus or minus 10 Pa).
  • Temperature for operation: not exceeding 60 degrees Celsius.
  • Operating humidity: max. 70 %.
  • Weight: 87 to 554 kg.

Filter replacement time depends on the capacity of the fixture. Normally 3 to 12 months (consult manual). Many manufacturers sell the filters in kits: two by two.

Before you buy a hood, it is advisable to ask the salesperson if there is a need to buy a charcoal filter for it or if it is already in the design.

The filter device is based on an absorbent that absorbs and traps pollutants. The absorbent can be in pellet or powder form. The filter housing is usually plastic.

A motor directs the air into the hood with a fan and drives it through the charcoal filter. Over time the filter becomes dense, thus reducing its absorption capacity.

Tip: In a room with a carbon filter hood, it is recommended to install an air ionizer. Passing through the charcoal, the air loses light ions, and ozone is no longer formed in it. Air without ozone can be called dead air.

Grease filters can be specifically designed for a particular manufacturer’s hood, or they can be universal, with the ability to adjust the size for any unit. Below is a ranking of the best universal disposable particulate filters.

Choosing such a hood, you should pay attention to the motor power. It is the one that will determine the efficiency of the appliance.

If we consider the quality of reusable grease filters, the first place is taken by stainless steel grids, the second by galvanized steel and the third by aluminum alloy. It is better not to take hoods with disposable filters, otherwise you will have to constantly monitor their frequency and the availability of replacement plates.

Recirculation models with charcoal filters are suitable for kitchens where it is difficult to vent to a shaft or outdoors.

The quality of the filter itself is important in selecting such a filtration system. The higher it is, the better will be the microclimate in the room. It is worth giving preference to proven brands, such as:
