1. Purification Technology
Purification technology refers to a series of techniques used to address indoor air pollution. Currently, the mainstream purification technologies used in air purifiers include photocatalytic technology, negative ion purification technology, ozone purification technology, and ionized cluster air purification technology. Photocatalytic technology products have a lower cost, but their disadvantage is that the free radicals' activity causes them to remain in the air for a shorter time, and their killing effect on viruses and bacteria is also limited. Negative ions are very beneficial to the human body and help with health maintenance, but due to the unstable technology of negative ion air purifiers, the released negative ions within 30-35 centimeters are the best distance for breathing. Beyond this range, it loses balance, and when the concentration is too high, it can kill some viruses and bacteria while also killing human white blood cells, potentially causing cancer, and thus becoming a killer of life. Sharp's net ion cluster technology works by ionizing water molecules in the air to become negative oxygen ions and positive hydrogen ions, which are balanced and stable and are unlikely to form ozone. It is the same as the negative oxygen ions and positive hydrogen ions in nature forests, which can effectively increase the oxygen content in the room and is the most effective in eliminating odors, bacteria, viruses, and dust mites.
2. Rated Power
The variation of rated power directly affects the power consumption of the air purifier per hour, which is also the cost of air purification. Of course, rated power is also related to the purification area and the amount of function. Generally, the air purifier with a larger purification area has a higher rated power. When considering rated power, it is necessary to combine it with the applicable purification area and function for comprehensive consideration.
3. Formaldehyde Removal Rate
Formaldehyde gas is a carcinogenic gas released from indoor decoration materials and furniture. However, it can cause nasal cancer, throat cancer, skin cancer, leukemia, heart and blood vessel diseases, etc. Therefore, formaldehyde is also one of the most important pollutants in indoor air pollution. The level of formaldehyde removal rate is the effect of this air purifier in removing formaldehyde. Thus, it can be regarded as an important reference factor.
4. Noise
To maintain indoor air quality, air purifiers often operate for a long time. If the noise is too high, it will cause certain noise pollution indoors and may affect normal sleep. Therefore, choosing an air purifier with low noise is also crucial.
In addition, the applicable area, air volume, and the type of filter used by the air purifier are also important reference standards. Therefore, a simple understanding of these primary parameters and their comparison will be very helpful when choosing the most suitable air purifier for yourself.
When choosing an air purifier that suits you, it is necessary to consider factors such as brand, price, purification ability, and service life. To fully understand an air purifier, we need to understand its important parameters and analyze them. This includes purification technology, rated power, formaldehyde removal rate, noise, etc. Consumers choose their own air purifier based on the above several factors.
