How to choose a kitchen hood without an air duct

The hood in a modern house is a necessary element, since the level of comfort in its presence increases significantly. All such devices are divided into exhaust and circulation. Hoods with the removal of polluted air outside the premises are more efficient. But what if it is impossible to equip such an air duct? In this case, hoods without venting are used, which pass air through the filter system, returning it to the kitchen already cleaned.

Cooker hoods fall into two broad categories:

1. With air extraction (flow-through). In such devices, the fan draws in air, passes it through the grease trap, and then directs the polluted air into the duct. Through the channel, it is thrown out of the room. If the ventilation duct is functioning properly, the air in the kitchen is constantly updated. Instead of exhaust air, fresh air enters the kitchen. To ensure high-quality operation of the supply hood, a constant air flow into the kitchen from the street.

2. Without air extraction (recirculation). Such devices are not connected to air ducts. They work on the principle of air recirculation. The engine uses a fan that drives air through two degrees of filtration. The first stage is a grease trap, which, in addition to grease, also traps dust particles, soot, and heavy types of fumes. Next comes the carbon filter, which purifies the passing air from foreign odors and the smallest particles that have passed through the grease trap.

The circulation hood does not require air to enter the kitchen. It only needs to be connected to the mains for its operation.

There are also types of hoods for the kitchen without an air duct:

When does it make sense to install a recirculation hood?

There are many reasons why the installation of a flow-through exhaust device is not recommended:

  • in a studio apartment. Additional air ducts that will be in plain sight will not add to the aesthetics of such a stylish apartment;
  • if the stove is located very far from the entrance to the ventilation;
  • if the kitchen was originally designed without taking into account the exhaust hood;
  • air ducts laid through the entire room can spoil the overall look of the kitchen;
  • ventilation ducts are not functioning properly. The air does not leave them, but returns back to the kitchen with all the available smells;
  • air outlet channels, as well as the hood itself, do not fit into the interior of the kitchen.

We also note that kitchen hoods without a vent to the ventilation are much easier and faster to install.

Tip: If there is a geyser in the house, the circulation hood would be an ideal option, since the flow system can create reverse draft in the ventilation shaft.

Pros and cons of hoods without air extraction

Before choosing a kitchen hood without an air duct, we recommend that you familiarize yourself with the positive aspects of these devices, as well as find out their negative points. With this knowledge, you will be able to choose for your home a device that would completely suit you.

Let's start with the positives:

  • the hood without a vent to the ventilation can be mounted not only in kitchens, but also in any premises, regardless of the presence of ventilation ducts in them;
  • there is no need to ensure the flow of air into the room. This is especially important for kitchens in which sealed double-glazed windows are installed, plus, cold air from the street in winter will significantly cool the room;
  • the circulation hood will perfectly fit into the interior of any kitchen;
  • requires little space, does not clutter up even small kitchens with its presence;
  • simple design that does not require special knowledge to connect. All work on its installation is easily performed independently;
  • practically does not require maintenance;
  • replacement of filters is carried out in a short time on their own.

Hoods for the kitchen without an air duct are not without drawbacks:

  • it is necessary to change the active filter element regularly, which leads to additional expenses. Usually the filter lasts for 3-6 months. After this period, the efficiency of the hood decreases;
  • such a device has less efficiency than a flow hood;
  • they are noisier.

What to look for when choosing

To choose the right circulation hood, you need to devote some of your time to get acquainted with the main parameters of this technique:

Dimensions

The device should not be smaller than your stove. Let it be better that its dimensions go a little beyond the dimensions of the hob.

Performance

The higher this indicator, the more air the hood can clean in 1 hour. It is considered normal if the air is replaced in the kitchen 12 times. To determine the required performance of the hood, you need to know the dimensions of the kitchen. The total area is multiplied by the height of the ceilings, and then multiplied by 12. For example, if the area of ​​​​the room is 9 squares, and the height of the kitchen is 3 m, then we get the required power: 9 x 3 x 12 \u003d 324 cubic meters / hour. This indicator is the minimum hood power suitable for installation in a given room, which is recommended to be increased by 30 percent.

Note: If the kitchen is combined with some other room, then the total area of ​​\u200b\u200bsuch an association is taken into account.

Speed ​​control

A high-quality recirculating hood for the kitchen should have at least 3 speeds to ensure the convenience of working with different evaporation rates.

Backlight

This is a very convenient addition that allows you to illuminate the hob. As lighting elements, LED lamps look preferable.

Filters

The filtration system consists of an external filter (grease trap) and a carbon filter. As grease traps, reusable metal meshes or acrylic fiber inserts are used. Disposable filters include sintepon, paper and non-woven filters. It is better to use reusable elements due to their cost-effectiveness.

Additional functions

  • an electronic display on the device panel will give all the necessary information about the performance of the hood without a pipe and its mode of operation;
  • the filter status indicator will remind the hood owner of the need to replace or clean the filter element;
  • automatic on and off sensors will allow you to fully automate the operation of the device;
  • the periodic inclusion mode will allow you to constantly maintain the freshness of the air in the kitchen;
  • The built-in timer allows you to set the hood to work according to a schedule.
