Coal hood: pros, types of filters, myths

August 20, 2020

When it comes to hoods, people immediately imagine a device of the current or combined type, hanging over the tile. However, manufacturers still offer extractor hoods with special carbon filters. Many simply do not know about their existence, others think, that they clean the air worse. Is that really the case?? Let's talk about the benefits of coal hoods, about the principle of their work, and how to choose the right appliance for your home.

Pros of filtration coal hoods

Kitchen hood filtration type undeservedly has a reputation as a useless device. And in vain, because it can be installed even there, where it is not possible to place an ordinary hood. Of its most undeniable advantages can be identified:

  • ease of installation and maintenance (mounted on the ceiling and even on the cabinet);
  • compactness;
  • ease of management;
  • no central vent connection required;
  • cheap filtration cleaner;
  • possibility of placement in the absence of central ventilation.

Based on this, you already have the opportunity to appreciate all the undeniable advantages of coal hoods for the kitchen. If you have ever had to install a hood yourself, then you, probably, remember, how difficult this process is in terms of site selection, installation of a corrugated pipe together with a lattice on a vent. Quite another matter with the hood without a pipe: to fasten a compact rectangular design will not be difficult even for an inexperienced craftsman.

types of filters

The principle of operation of the coal hood is extremely simple: it consists of two filters with different degrees of purification, which provide air recirculation. That is, they do not renew the air in the room, and remove pollution from it in the form of fumes, soot, fat particles. That is why this device can be installed even in rooms, where there is no ventilation window.

The process of air recirculation consists of two stages:

  1. Rough cleaning. The air passes through the first filter, which retains the largest particles of fat and soot.
  2. Fine cleaning. The carbon filter adsorbs the smallest particles of dirt and odor from pre-cleaned air masses. Only clean air comes out.

Both filters must be serviced regularly. The coarse filter requires periodic rinsing using the tool, fat-splitting (more about care - in the article on how to clean the hood from grease). Manufacturers also offer disposable types of such filters, so as not to take away from housewives extra time for washing.

Fine filters also change according to the service life. They are always disposable, however, it is not necessary to look for filters instead of the same manufacturer. In stores you can find universal types, which are suitable for any hoods.

Myths about coal hoods

Because filtration hoods are not common among the townspeople, there are several myths surrounding this technique, which do not correspond to reality. Let's take a look at the most common ones and find out, whether they are true.

productivity

Myth №1: hoods have greater productivity, than coal, as provide an inflow of fresh air. In fact, the performance of both devices will depend not only on the principle of operation. In the case of corrugated hoods, the quality of their work will be strongly influenced by the length of the pipe itself, the number and angle of its bends. The performance of the cleaning filters will be the better, the cleaner and newer they are. Such factors cannot be ruled out, as the traction force of the ventilation system in the house and the types of windows in the room. As you know, wooden windows provide better air penetration from the outside, than plastic.

The human factor also influences: there are kitchens, on which something is constantly fried, and there are lovers of food, steamed.

replaceable cartridges

Myth №2: a replaceable charcoal hood cartridge should only be from the same manufacturer, standing on it. Maybe, it used to be so, but now production is not standing still, focusing on consumer demand in conditions of fierce competition. Universal carbon filters will be offered in specialty stores, which are suitable for any model of cleaners at reasonable prices.

odor removal

Myth №3: hood with ventilation faster and better copes with the removal of all odors. Again, opinion is very subjective and depends on many conditions. But practice shows, that coal hoods clean the air also well and at the same speed, as well as streaming species.

Microclimate in the kitchen

Myth №4: hood affects the temperature in the kitchen. But this is the truth, only it applies to hoods of the current type. Their principle of operation is based on removal of air from a premise together with a smoke and soot and maintenance of inflow of fresh air masses.. Because these masses will come from the street, then they will be cold in the cold, or warm in the heat. In contrast, recirculation, which is carried out by carbon filters, will not affect the temperature of the kitchen.

Choice tips

Rectangular flat hoods without drain differ in the greatest compactness. They operate in recirculation mode and do not require a complex connection. If you are attracted by the unprecedented compactness, then your choice will be obvious. Moreover, you will not need to run around all the shops in search of a suitable filter brand.

If you think so, that the inflow of fresh air from the street is very important in the ventilation system in the kitchen, then you can consider the combined types of cleaners. They can operate in recirculation mode, adsorbing air pollution, and in flow mode. Such hoods are connected to the ventilation system and ensure the circulation of air masses, which is so liked by housewives.
