Selection of household air filter;
First, you need to define the use area of the air filter.
Because the air volume of different air filters is different, there will be some differences in purification efficiency and applicable area, so when choosing an air purifier, we should consider it according to our own situation.
Defender air purifier adopts 360-degree air inlet and 360-degree cyclone air outlet design. No matter it is placed in any corner of the room, it can purify the air in a large range. Generally, it can purify the space environment of 50 to 100 square meters.
Second, it is necessary to clarify the filtration technology of air filters.
According to the different places of use, it can be generally divided into household air filters, commercial air filters, medical air filters and so on. For household air filters, HEPA filters and other filtering materials are generally used (this chip can generally filter 99.7% of pollutants as small as 0.3 micron in the air), and only in this way can the indoor air be truly filtered.
Defender air filter can filter 99.98% pollutants as small as 0. 1 micron.
The exhaust port of Defender air filter is a patented and unique technology, which increases air flow and exerts stronger air purification ability.
Third, it should conform to the intelligent and humanized design.
With the continuous development of science and technology, household appliances are becoming more and more intelligent and humanized. When purchasing air filters, we should also start from this aspect to see if it is easy to operate, low noise and energy saving.
Defender air filter has three speed gears and can be programmed. Simple top disassembly device releastm full packaging technology releastm; The running sound is low (generally around 47.6dB); Energy saving (compared with other air purifiers, it can save 40-75 watts)
