Filtration is almost always used to purify the air. It usually requires pumps and fans to force air through filters. They contain components that are in the air. The photocatalytic filter located in air purifiers decomposes organic pollutants into harmless substances. This is its advantage over its predecessors: no replacement is required, and the performance does not change over time. This device will be discussed in the article.
Design features and principle of operation
Photocatalytic purifier includes catalyst and UV lamp. The material of the device can be porous glass - a substance with a high absorbent effect. With it, even small particles are kept in the air. Titanium oxide is applied to glass that transmits light. He is the catalyst.
UV rays enter the catalyst layer, and under their influence, titanium oxide becomes a strong oxidizing agent that can decompose organic components into harmless substances - water and carbon dioxide. The water evaporates and therefore the air in the room is humidified. The carbon-photocatalytic filter works the same way. Reviews confirm that the device makes living in an apartment more comfortable.
Efficiency
Photocatalytic filter eliminates contaminants. With it, you can get rid of:
- dust and dust mites;
- carpet and fabric pile, animal hair;
- skin flakes;
- spores of mold, pollen, other allergens;
- tobacco smoke, formaldehyde, soot, carbon monoxide and exhaust gas;
- odors of spoiled food, fumes;
- toxic organic ingredients.
In addition to the above, the device is able to purify the air from bacteria and viruses, as it becomes disinfected. Numerous reviews testify to the effectiveness of the device, since it performs many different functions, and does it well.
Benefits
The photocatalytic filter air purifier has the following features:
- Excellent level of cleaning. The device eliminates viruses and bacteria by approximately 99%. The efficiency of the device is many times higher in comparison with the carbon filter.
- Elimination of delayed rubbish. Inside the instrumentthere will be no dust and bacteria like other devices, so the equipment cannot infect.
- Self-cleaning function. Since dirt does not accumulate in the device, there is no need to change filters, there is no need to spend on consumables, maintenance of the device. You just need to regularly (every 1-3 years) change the UV lamp.
- Fast odor-free air purification.
- Economical power consumption - only 30-65 Wh. In other types of apparatus, a jet of air is driven under great pressure in order to penetrate into a dense filter. This is not required by the photocatalytic device.
- Environmental friendly and safe. Pollution breaks down into safe components that are not harmful to humans and the environment.
- Ease of maintenance. Vacuum the device once a year.
Thanks to these advantages, many people choose this device for their homes. Given the reviews, many people prefer to purchase this particular device. Then the room will have a favorable microclimate.
Flaws
But the photocatalytic filter also has disadvantages:
- Does not remove inorganic contaminants. For example, it practically does not reduce construction dust, and it is advisable to choose another device for a room with a long repair.
- Air purification from bacteria can adversely affect the child's immunity, so the device should not be installed in the nursery. It does not affect adults.
Scope of application
Photocatalyticthe filter in the air conditioner or purifier is designed to protect the space of the room from contaminants that adversely affect human he alth. It is used as a prophylaxis to fight infections and allergies. Reviews confirm the need for devices in residential areas, since there is usually dry air. The device is suitable for domestic premises, offices, hospitals, kindergartens and other institutions. Installation of the device is simple, it does not require special skills. The device is installed on a dry surface out of the reach of children. It is advisable to place such equipment in an area of heavy pollution.
Compared to traditional devices, these filters do not accumulate pollution, but destroy them. This is due to photocatalysis - the acceleration of ongoing reactions due to the catalyst and the light flux of different spectra. The air in the room where there is such a device will be clean.
Functions
The cleaner may have additional features:
- The timer is used to set the operating and shutdown times.
- The remote control allows you to switch modes remotely.
- Setting the fan speed allows you to switch the device to different modes, which determines the speed and noise level of the fan.
- Pollution detectors measure the amount of dust and gas in the air. When the preset level is exceeded, the purifier switches itself off. This function allows you to control the intensity of work.
- Display. Many cleanersliquid crystal screen, which contains information about the modes and operating time.
- Indicators reflect information about the operation of the device.
- Fragrance. Such a device will emit a pleasant aroma.
Operation
Manufacturers advise regular replacement of filters for normal operation of devices. This will extend the life of the device. If unpleasant odors appear, the filter should be changed before the end of its useful life.
To ensure that the air is always clean, it is desirable that the entire volume be processed at least 2 times per hour. The use of even the best air purifiers does not saturate the air with oxygen, so it is necessary to ventilate the room regularly.
Choice
To choose a suitable device where a photocatalytic filter is present, some nuances must be taken into account:
- Power. This indicator determines for what area the device is intended. If the power is insufficient, the air will not be cleaned properly, and an apparatus that is too strong will consume a lot of energy. When planning to use the device around the clock, it is advisable to select low power consumption.
- Presence of HEPA filters. The equipment captures even small solid contaminants. It can trap pollen, pet hair, and dust. Such filters are not always available in photocatalytic cleaners, but such a device is needed if there is an allergic person in the room.
- Functions. Before purchasing a purifier, wherethere is a photocatalytic filter, you need to find out about the type of pollution in the room. If it contains inorganic impurities, then a device with an additional degree of purification is necessary. It is advisable to purchase a purifier with a hygrometer, a pollution sensor and an automatic cleaning function.
If the device will be used infrequently, you should not purchase it with a humidification function, because the water filled in the tank stagnates, blooms, and there will be plaque inside. Some manufacturers combine 2 devices in the device. A photocatalytic purifier may have an ionizer, additional filters, air humidifiers, a hygrometer that allows you to control humidity. There is a possibility of other functions being present. Before buying, you should familiarize yourself with the characteristics of the selected device, as well as find out everything about it from the sales assistant.
