Air Purifier Evaluation,Give Consumers Safe and Qualified Products.
How to solve the air formaldehyde, PM2.5 and other pollution, many consumers will think of air purifiers. However, people’s impression of air purifiers, in addition to being able to purify the air, another is that the products are large in size. In addition, the filters for filtering formaldehyde also carry the risk of secondary pollution. Would you believe that we are now going to share an air purifier that is small enough to carry around with us and that can break down formaldehyde without worrying about secondary pollution?
So now, let’s start our air purifier evaluation journey.
Air Purifier Evaluation,Appearance Appreciation
This air cleaner has a white frosted plastic casing and a matcha green air outlet. With its rounded design, the overall look is very simple and elegant. Small enough to fit in a backpack, it takes up no space on your computer desk or bedside table.
The fan blade of the air outlet can be adjusted in the up and down direction, the adjustment angle of 60 degrees, where you want to blow.
There is only one button on the front, all operations are completed with one key. Press once to turn on, and then press again to switch gears.
On the back is a micro USB port. It is a pity that the TYPE-C port is not used. It can work with 5V power supply, as long as there is a rechargeable battery, it can continue to work.
At the bottom is the air inlet.Turn on the bottom cover and you can see the coarse filter.
Air Purifier Evaluation,Purification Principle
This purifier uses photocatalytic technology. Photocatalyst, irradiates titanium dioxide through UVA ultraviolet light to break down water in the air into hydroxyl radicals with strong oxidizing properties. The hydroxyl radicals can break down air pollutants, such as formaldehyde, into water and carbon dioxide. This is compared with ordinary air purifiers that use activated carbon adsorption, not only do not have to worry about secondary pollution of formaldehyde, and consumables are much less.
In addition, the hydroxyl radicals produced by photocatalyst can also kill airborne bacteria, pathogenic microorganisms, etc. Compared to the use of UVC ultraviolet light with a wavelength of 100-280nm, there is no need to worry about the production of ozone, which is harmful to humans.
This air cleaner also filters PM2.5 differently from ordinary air purifiers. It is equipped with a 3 million level of negative ion generator, using the primary filter plus the negative ion sedimentation way to evolve PM2.5. at the same time, negative ions can also make the air fresh, refreshing, as well as improve efficiency.
Air Purifier Evaluation,Performance Test
After understanding the purification principle, we have to carry out some field tests to see if it is really so amazing?
In order to visually detect the purification capacity, we placed the product into a glass box with a length of 50*30*40, and the test gear is a high-speed gear.
PM 2.5 TEST
We let the PM2.5 of the air inside the glass box rise rapidly by burning the cigarette cake and turn on the air purifier for purification. Then use the laser haze meter to measure the change of PM2.5 concentration in the glass box.
As you can see, the initial PM2.5 concentration inside the glass box reached 153mg/m3, which has reached a level where the air quality has reached heavy pollution.
After we turn on the air purifier, we can see that the PM2.5 concentration inside the glass box decreases rapidly. In just two minutes, the concentration of PM2.5 was reduced to 35mg/m3 and the air quality was purified from heavily polluted to excellent. It also took only 4 minutes to purify the PM2.5 concentration to 10mg/m3.
It can be seen that the air purifier’s ability to purify PM2.5 is still quite good.
Formaldehyde test
Everyone is most concerned about the purification ability of formaldehyde. We take a certain amount of formaldehyde solution, put it in a glass box and let it evaporate for 15 minutes. Turn on the air purifier to purify the air, and use the formaldehyde meter to measure the formaldehyde concentration in the glass box.
After the formaldehyde solution volatilized for 15 minutes, the formaldehyde concentration in the glass box reached 0.556ppm(556mg/m3).
The formaldehyde concentration in the glass box dropped to 0.411ppm(411mg/m3) after 5 minutes of turning on the purifier .
After 15 minutes of opening, the formaldehyde concentration in the glass box dropped to 0.152ppm(152mg/m3).
From these two tests, it can be seen that this air purifier is small but capable. The purification ability is really amazing, and we didn’t expect it to have such purification ability. However, it should be noted that this test was carried out in a small and relatively closed test box. If it is actually placed on the desktop, its purification speed may decrease slightly. However, in such a small volume, it is obviously unrealistic to ask it to be able to compare the purification speed with various behemoths. The brand also pointed out that the air purifier is suitable for the space of 8~10m3.
Summary of Air Purifier Evaluation
The small size makes this air purifier suitable for many scenarios, whether it is next to the computer, on the bedside table or in the car, or even carry it around with you, it can easily handle it. Of course, the most important thing is that it does not disappoint in its purification ability, so we can breathe good air everywhere. So what do you think of this air purifier? How many points would you give it?
