Any educated person understands that city air far does not correspond to ideals of natural purity. Often it is simply dangerous to human health. To protect the family from harmful impurity in the inhaled air, people use the special cleaning equipment. How it is correct to choose the air purifier, without having lost in their variety? Let's consider all nuances of this action.
The industrial revolution which has appeared on the European continent in the 18th century has made big changes to relationship of Homo sapiens and nature. With advance of technical progress the homo sapiens had had benefits allowing it to live comfortably. But at the same time also the environment ecology has considerably worsened. Air became polluted.
Today in the solution of this problem household air purifiers have come to the rescue. Task of devices – elimination of dust, small pollution, pincers, mold from surrounding space.
Types of cleaning
The systems of cleaning happen two types:
- water;
Each option has the design features. What cleaner is considered the best? The multipurpose device possessing the big list of merits.
How to choose good cleaner
Correctly to choose the device for the dwelling, it is necessary to study characteristics of the equipment and to understand the principle of its action. The air cleaner is the fan having the filter which carries out giving to the room of air in the design, making in passing its cleaning. At the expense of it it is possible to block dust, small particles of dirt, unpleasant smell, to carry out disinfecting of the arriving air, to get rid of the industrial smoke which is present at big cities.
Such duster will become useful allergic persons who need to breathe clean air. Also similar ionizer perfectly will be suitable for families with little children as need daily disappears to carry out damp cleaning.
Main characteristics of models
Choosing the device for cleaning of the house, preference should be given to samples with air ozonization function, otherwise indoors there will be "dead" microclimate which has lost the natural net charge and is unhealthy. Before buying ozonizer, it is necessary to pay attention to the following characteristics:
- device power;
- quality of air exchange;
- noise level.
Power of the air cleaner determines device performance – as it is capable to expedite the function assigned to it qualitatively. At selection of the equipment by all means consider the room space for which high-quality air purification is necessary. The choice of units for the apartment should be limited to models which ensure functioning with the square area of 20-40 meters. Big indicators of power are characteristic of the device of industrial function.
When the room big, it is necessary to choose the equipment with high power. When it comes to air exchange, it is extremely important to consider degree of pollution of the air arriving from the outside. If this high rate, the equipment becomes better to carry out own functional duties. The following important selection criterion – the noise level made by the equipment. When children or people working at the nights indoors live, it is more reasonable to buy almost noise-free model of the unit.
Then by all means pay attention what the device has operating modes besides the basic:
- with air ionization;
- with the ultra-violet lamp.
Solve before purchase whether additional devices in the form of the timer or the remote controller providing distant control are necessary. Choosing indoors the place for expected placement of the device, by all means evaluate its dimensions and design. Usually household air cleaners are compact, they do not demand a lot of place for mounting.
The good device at which there is effective air purification has to perform the following functions:
- to delete dust, flower pollen, unpleasant smells;
- to clean space from cigarette smoke, viruses and bacteria;
- to detain small particles and hair of pets.
The air purifier is rather difficult device therefore important the nobility what filter is installed on model and how many such filters is present.
The overview of filters for air cleaners
There are different types of these devices:
- Coal (adsorptive, deodorizing). By means of this filter there is removal of various gas impurity and smells. In its basis the effect of activated carbon is put. Carry adsorbiration of volatile gaseous compounds of air, high efficiency of removal of smells to advantages of the device.
- Nir the filter possessing large-scale of catching of small particles. The device is executed from cellular material as a part of which there is fiber glass. Standard filters of this type are capable to block receipt to 90% of all pollution. Advantages – simplicity of mounting and use and also availability. The ability to do not miss only mechanical mud connections belongs to shortcomings. Gaseous substances do not accumulate in the NERA-filter. Dirt collects on filters and at untimely leaving acts as pollution source. When removal of the filtering element is carried out – it is required to be carried out carefully as it is dangerous to all people around, on it various pathogenic microorganisms actively breed. It is necessary to organize special utilization of the NERA-filter. When high-quality extent of filtration is provided, the device creates the considerable resistance to the air stream coming to the room. NERA-filters are equipped with small capacity for the caught pollutants therefore need frequent replacement.
- The electrostatic filter provides removal of dust from air. The principle of operation of the device is based on pulling of charges of opposite polarity. Moving on the camera where there is ionization, particles of dirt are loaded positively, then settle on plates with negative charge. Advantages of the electrostatic filter consist in high efficiency of removal of liquid aerosols and firm connections. The device does not need change of consumables and elements. Has the long period of operation. Like the filter carry to shortcomings of it that pollution settle on junction plates, frequent service is required, in technological process of work ozone and oxides of nitrogen which are considered as very toxic agents get into air.
- The mechanical filter is ordinary small grid which carries out preliminary air purification. By means of the device, hair of animals and large particles of dirt are removed.
- The photocatalytic filter is based on action of photocatalysis. The main advantage of process – full disintegration of the toxic connections which are present at the environment to oxygen, water and also carbon dioxide. In comparison with other air cleaners which just detain in time dirt in big sizes the photocatalytic models destroy dust up to 0.001 microns in size. Cleaners of this kind effectively cope with such air pollutants: tobacco smoke; mold; volatile chemical compounds; carbon monoxide; exhaust gases; bacteria; viruses; dust tick.
- Ultra-violet filter. The principle of its work and design features are based on action of UF of the radiation of the quartz lamp which is perniciously influencing pathogenic microorganisms. Modern air purifiers on the basis of this device are capable to resist both to microorganisms, and any organic infections. And they are capable to decompose organic chemistry to safe substances: water and carbonic acid. Especially involves opposition of ultraviolet against fungus and mold as disputes which are airborne are destroyed. Advantages of UF of cleaners: usability, low cost. Such devices have no replaceable filters therefore do not demand regular and expensive service. Have the small weight and the sizes, differ in small energy consumption.
- Washing of air – one of types of air cleaners. These devices have no filter, but purify air by means of water with its simultaneous moistening.
Service regulations
Choosing air cleaner model, it is necessary to consider the next moments:
- in the device washing air it is necessary to add water as often as possible;
- in the electrostatic device of times a week it is necessary to wash out electrostatic plate;
- in the ionizer and cleaner ozonizer it is possible to vacuum filters once a month;
- NERA-filters demand frequent replacement of filters.
Producers of air cleaners
In the market of the climatic equipment models of firms enjoy wide popularity:
- Panasonic;
- Ballu;
- Daikin;
- Plaston;
The offered designs are characterized by excellent technical and esthetic characteristics.
Design of air cleaners
When choosing model important point for many consumers is the question of design execution and its harmonious combination to the general registration of the room. Modern producers release air purifiers of the various sizes. There are samples:
- floor;
- wall;
- the incoming.
Each of the listed models has number of undoubted positive technical qualities. As for esthetic characteristics, all designs possess in imperceptible gray color. It allows filters to fit ideally into interior of any space, without attracting to itself(himself) close attention of strangers.
