Some friends may have noticed that we often write articles about air purifiers, because the truth-seeking labs have received professional training from third-party authoritative testing organizations, and the most transparent one is the air purifier ( Hereinafter referred to as empty net).
We can't recommend which brand which model is better than the net. After all, we have limited products, but we can talk about the net purchase skills in principle and standards, and guarantee a dozen.
Some air-cleaning products have been added to the air humidification function in the market. The two-in-one design seems to save trouble, but the technicians who have tested thousands of empty inspection agencies told us that purification and humidification cannot coexist.
Is the empty net humidification function not necessary?
Empty net is really not suitable for adding humidification function, not because the humidification function itself is not reliable, but the addition of moisture will make the HEPA filter in the empty net become damp or even mildew, which will breed mold bacteria and cause two indoor air. Secondary pollution.
Empty net HEPA filter is easy to mold in high humidity environment
At present, the air purification function of the humidification function is based on the principle of physical evaporation. The air in the humidification filter (not the filtered HEPA filter) is sent to the ambient air through the fan air supply, and the woven filter is originally a dense one. The water collecting structure, which is located close to the HEPA filter, can easily cause mold to breed bacteria.
Humidifying woven filter commonly used in air cleaning, generally located between HEPA filter and fan
Therefore, the humidification function in the empty net will make the woven filter and the purified HEPA filter responsible for humidification moldy under the action of water vapor and temperature. Although some manufacturers will use the dehumidification material to adsorb too much moisture, it is also a glass of water, the effect is limited.
Similarly, if you want to use both air and humidifiers, try not to use foggy humidifiers, and don't put them too close together, and pay attention to the indoor relative humidity should not be too high, otherwise the net HEPA filter may also have influences.
By the way, talk about the humidifier.
The working principle of the humidifier mainly includes ultrasonic vibration and physical evaporation. The former uses vibration to atomize the water vapor, and then sends the mist to the ambient air through a fan. The humidifier is characterized by obvious water mist from the work. Sprayed out of the machine.
Ultrasonic vibration humidifier has water mist spray when working
The physical evaporative humidifier uses a fan to send the naturally evaporated moisture attached to the humidifying filter to the air. This humidifier does not have water mist, but the filter may be moldy in a hot and humid environment.
The humidifier that uses ultrasonic vibration humidification humidifies quickly, but since the vibration will bring the calcium and magnesium ions in the water to the air at the same time, white spots will appear on the furniture floor after a period of time, which are precipitates of metal ions in the water.
The physical evaporation humidifier has a slower humidification rate, but natural evaporation can avoid the generation of white spots. Regardless of the type of humidifier, the water source used should be as clean as possible to avoid secondary pollution of the air.
Physical evaporation humidifier does not produce water mist, but is less efficient
Ultrasonic vibration and physical evaporation humidifiers have their own advantages and disadvantages, and manufacturers basically add disinfection and filtration and purification functions to these products to ensure the hygiene of water vapor, but for the sake of caution, it is recommended to use a physical evaporation humidifier, but also pay attention to regular replacement. Humidifying filter.
I have a rough explanation of the grudges between empty net and humidification. I believe that when you buy empty net, you will not be dehumidified. This additional function blinds your eyes. The so-called industry has specialization. The all-in-one product may not necessarily be Ok.
Silicon Controlled Rectifier (SCR)
Silicon Controlled Rectifier (SCR) is short for silicon controlled rectifier. SCRs are available in one-way, two-way, turn-off, and light control types. It has the advantages of small size, light weight, high efficiency, long life, easy control, etc. It is widely used in occasions such as controllable rectification, voltage regulation, inverter, and non-contact switches and other automatic control and high-power electric energy conversion.
