If you are thinking about buying a hood, you'll probably come across the question of which model is better - with tap or circulation. Both methods of removing polluted air are practical and effective. But what is right for you, we will try to decide.
Extract hoods - how they work and what is the advantage of
Such a model works on an air replacement system - contaminated "drawn" into the pipe, and then this air is vented to the ventilation system( or to the street).Thus, smoke and pollution products will be completely removed from the premises. These extracts are equipped with a special fat filter, which protects the parts of the device and the engine from soot, grease and dust. What is the advantage of drain hoods?
- They effectively and qualitatively purify the air;
- High power;
- Differs high performance( due to the fact that the models are not equipped with a carbon filter, and there is no pressure loss when working through this filter).
There are such drawbacks and their disadvantages, which are directly related to the merits. For example, next to high power is increased noise, especially if the device will work at maximum mode.
Next to high-quality cleaning is the process and technology of mounting the hood. Such a model requires installation of a vent system and strict compliance with technical requirements( for example, if the ventilation of your apartment is not designed for high load, then the device simply does not meet its characteristics during operation).
Recirculation hood - another operating principle, other advantages of the
This model will work on a different principle - first the device sucks the polluted air inwards, where there are two degrees of purification. Rough cleaning is carried out through a simple fat filter, and more delicate cleaning is carried out through a sorption filter in which activated carbon is used.
This air, cleared of soot, fumes and grease, is then returned to your kitchen. That is, there is a process of air circulation. There are several advantages to this model:
- It is compact, light and has a neat appearance;
- It is easy to install and does not require the installation of a vent;
- It effectively cleans the air and does not create much noise.
As for the shortcomings, it is worth noting the requirements for replacing filters. The carbon filter will need to be changed once in 4-6 months( the more exhausting the filter works, the faster the filter becomes dirty), and the fatty filter should be cleaned and washed ideally - once a month. Otherwise, your hood will lose its effectiveness.
Which model is better? Choose based on the power you need and the installation requirements. More powerful, but more demanding for installation - the draw-off model is useful for those who often cook a large number of dishes and smokers( the hood will cope with tobacco smoke perfectly).
The recirculation model will like its compactness and ease of installation, though, the filter state will need to be monitored.
