Air Purification - Health Care
We especially thoroughly clean the water we drink, we discard food with additives harmful to our health, we dress in breathable clothes, we build houses from environmentally friendly building materials, but we forget about the air around us. Air is every moment of our life, we will take care of its purity.

Air transparency is an illusion
The air around us seems transparent, as it is clean and safe.
But this is an illusion, if you look at the air through a sunbeam, you will see a huge number of tiny particles of dust.
In addition to dust and dust mites, the air contains the hair of your pets, the smallest particles of the skin of people and animals, the pollen of all kinds of plants, viruses and bacteria, and spores of fungi.
Just scary!
And all this negatively affects the health of a person, especially young children - all this causes allergies, the infection provokes the disease, and as a result, immunity decreases.
Progress has come to the point where the window begins to open is not safe for life.
If there is a car under the window, exhaust fumes from it can poison a person.
Conclusion! To improve the quality of life, you must purchase an air purifier.
Cleaning methods
Since air pollution has various reasons, different filters are used to clean it.
The air purifier itself is, to put it more simply, a box with a set of different filters.
Air passes through these filters before entering the room and leaves all unnecessary on the surface of the filters.
Those. different types of filters are used for cleaning, each filter has its own task.
By combining several filters into a single whole, we get the opportunity to solve several problems at once.
All filters can conditionally be divided into several groups:
-
retarding mechanical particles;
-
disinfecting filters, they destroy or inhibit the development of microorganisms;
-
deodorizing filters - capable of absorbing odor and gas.
Some filters can perform several functions at once.
HEPA - filter for air cleaner
This filter is the most popular filter for mechanical air cleaning.
It is capable of retaining 99% of the contamination of 0.3 microns in size.
This filter traps the most common allergens in the form of plant pollen, animal dander, fungal spores, etc.
HEPA - the filter is designed very simply - it is based on a material similar to paper, the larger the area of \u200b\u200bthis filter - the more effective it is.
To increase the area, HEPA filters are made corrugated.
HEPA - filters cannot be restored, therefore, as they become dirty, they are simply replaced.
Service life directly depends on the place of the multi-stage cleaning system where it is located.
But because this filter is not expensive - it is put as the first stage of cleaning.
It can serve from several months to several years.
Electrostatic air cleaner filters
Electrostatic filters also clean the air of dust and certain allergens.
Their work is based on the physical property of attracting uncharged particles.
Dust particles of air, getting into the filter, are electrified, then stick to a special plate with the opposite charge.
Electrostatic air purifiers are inexpensive because they do not require filter replacement.
From time to time a plate with adhering dirt is removed and washed in water.
Such a filter can work alone or serve as one of the cleaning stages.
Charcoal Air Filter
HEPA - filters and electrostatic filters can clean the air only from mechanical impurities.
From all volatile compounds in the form of odors and gases, other filters protect and the most widespread are coal.
Activated carbon is an excellent sorbent, so in air purifiers it absorbs odors and all kinds of chemicals.
Since during operation the carbon filter is clogged - it is periodically necessary to change it.
Some companies produce models of air purifiers with a washable carbon filter.
Photocatalytic air purifier filters
Photocatalytic filters are very promising.
Their work is based on the ability of certain substances to oxidize and destroy molecules of chemical compounds, remove odors, destroy viruses, bacteria and all kinds of harmful pollution of organic origin.
The additional use of an ultraviolet lamp enhances the operation of this filter.
Under the influence of ultraviolet radiation, the filter restores its oxidizing properties and therefore serves for a long time without replacement.
Disinfecting, other air cleaner filters
For air disinfection filters with various extracts from plants are used.
Filters containing silver are popular.
Air ozonation also kills bacteria.
The life of each filter depends on the installation location inside the cleaner.
To remove part of the load from the main filters, many manufacturers put prefilters on the air purifiers.
Prefilters are pre-filters, they are grids capable of capturing large particles of contamination.
Many models of air purifiers have additional functions, they not only clean, but also moisturize and aromatize the air.
Ionizer air cleaner
It is known that after a thunderstorm it is easier to breathe.
Improving the well-being of a person is explained by the saturation of air with negative ions.
Air cleaners often have ionizers in their device.
An ionizer is a device capable of reproducing negatively charged ions - they are actively involved in the process of air purification.
Ions transfer the charge to the dust particles, they stick together with each other, forming larger particles.
These large particles are well retained by filters.
The use of ionization can destroy harmful microorganisms already in the air.
Air wash or water filter
Air washing is an alternative to a multi-stage air cleaner.
Normal water serves as a filter.
There is a housing with a drum, water is poured into the housing, a fan draws in air that passes through a rotating drum.
Dirt particles in the air are wetted, remain in the water, and clean air enters the room.
Sinks not only clean, but also humidify the air.
When washing, the humidity level in the room is maintained to a comfortable 60%.
Sinks do not need to change the filter, dirty water is drained, the container is washed, filled with clean water and forth.
But the wash can only hold particles larger than 10 microns.
Sinks cannot eliminate odor and gas.
Questions about using an air purifier
Air cleaners work reliably, do not require installation, only if necessary, replace or wash the filters.
Replacement filters are easy to buy in the same place as the air purifier.
Very often, manufacturers assemble filters in a single unit, it can be replaced as a whole.
Filters are easy to change, it does not require special skills.
Air cleaners are usually placed on a table or on the floor, the floor is the best placement.
The place must be open so that the device can freely take and blow air.
Basically, air purifiers can work around the clock, some models have a quiet mode for night time.
The air purifier is a compact device and mobile - it can be moved from room to room.
About the need for ventilation
The operation of the air purifier does not cancel the ventilation mode, since the air purifier can clean the air of any muck, but cannot make up for the loss of oxygen.
Therefore, if the ventilation in the house can not cope, it is necessary to open a window for ventilation.
But everything should be in moderation.
Otherwise, if the window is constantly open, the air purifier will not cope with air purification.
Air purifier operation in automatic mode using a sensor
Modern models of air purifiers are equipped with sensors for the automatic operation of air purification.
The sensor is able to respond to air pollution, to pungent odors.
The sensitivity of the sensor can be adjusted to your preference, i.e. adjust the sensor so that it does not work very often.
