First, look at the brand.
Choosing a brand is a key step. There are many brands at home and abroad, such as Desen, Mindray, Panasonic, Philips and Yuyue. The first thing to look at is brand reputation. It is safer to choose a big brand, but the price is also higher.
Here, Bian Xiao suggested choosing a joint venture brand for the following reasons:
1. The joint venture brand has a better reputation in the domestic market and can better solve the problems of quality and after-sales.
2. There are many sales channels for joint venture brands, which are more convenient to purchase and relatively more competitive in price.
3. The technology of joint venture brand is more suitable for domestic climate, environment and other conditions.
Second, look at the applicable area.
The applicable area of each air disinfection machine is different. When buying, you should choose the corresponding products according to your own housing area. If the area is too large, the use effect will be discounted; The area is too small to achieve sufficient disinfection effect.
Third, look at the price.
Prices are everywhere, and the prices of disinfection cabinets are also uneven. Although the price of choosing domestic brands is relatively more close to the people, there is still a big difference in price. For the same model of air disinfection machine, there may be a price difference of several hundred yuan between different manufacturers. Therefore, when purchasing, you need to compare the prices and be aware of them.
Fourth, look at the filtering method.
As we all know, the core function of disinfection cabinet is to filter harmful substances in the air, so the filtering method is a very important factor when purchasing. At present, air disinfection machine filtering methods in the market can be divided into three categories.
1. Physical filtration: the harmful substances in the air are blocked in the filter by using physical filtration methods such as screen filtration, which has the advantages of fast filtration speed, easy cleaning and low power consumption.
2. Chemical adsorption: Using activated carbon and other materials to adsorb harmful substances in the air has the disadvantages of limited adsorption capacity, irregular replacement and high maintenance cost.
3. Photocatalyst filtration: Photocatalyst materials are used to accelerate the oxidation reaction in the air through ultraviolet rays or infrared rays, and the harmful substances in the air are converted into harmless substances, which is more environmentally friendly, but the filtration speed is slower.
Fifth, look at disinfection methods.
Disinfection method is one of the main factors to judge the quality of air disinfection machine. At present, there are many disinfection methods in air disinfection machine on the market.
1. ultraviolet disinfection: ultraviolet rays are used to kill harmful microorganisms in the air, which has a strong sterilization effect, but it needs to be used safely.
2. Ozone disinfection: microorganisms are decomposed by ozone oxidation, and bacteria and viruses in the air are completely killed, but ozone is harmful to human body.
3. Plasma disinfection: releasing high-voltage ions into the air for disinfection has a good effect, but the price is relatively high.
Sixth, look at the additional functions.
Some air disinfection machine also have the function of deodorization and humidification, which can be purchased according to actual needs. However, it should be noted that the more functions air disinfection machine has, the higher the price will be.
The above six points are the factors that should be paid attention to when purchasing air disinfection machine, hoping to help friends who need to purchase air disinfection machine.
