In the summer, many people believe that the air quality is relatively good. However, this is not the case; for example, formaldehyde, which everyone talks about, evaporates more in the summer. The concentration of indoor formaldehyde content increases by 0.15-0.37 times for every 1 °C rise in room temperature at home, and when the room temperature reaches 34 °C and the relative humidity of the air reaches 50%, the concentration of formaldehyde volatilized exceeds the national Indoor Air Quality Standards by 5.53 times.
Formaldehyde is an unavoidable topic when it comes to indoor air pollution. So, how can we get rid of formaldehyde more effectively?
In general, the most common methods for removing formaldehyde are ventilation, plant adsorption, and charcoal adsorption. The ventilation method has a certain effect, but it is subject to greater restrictions; the plant method is weak; charcoal, although it can adsorb a lot of formaldehyde, but the use of about 8 days saturated, need to be replaced diligently, or adsorption into the formaldehyde will not only overflow, but also may produce new pollutants. So, what kind of air purifier is capable of effectively removing formaldehyde?
In fact, the state has given the answer as early as March 2016, the new national standard of air purifier clearly affects the air purifier purification effect of the four core indicators, namely CADR (clean air volume), CCM (cumulative purification volume), energy efficiency level, and noise standards. is an important parameter indicator in the new national air purifier standard.
CCM indicator: the total weight of pollutants (particulate matter or formaldehyde) purified when the CADR value reaches 50%, measured in milligrams. The CCM of particulate matter is expressed by P, the highest level is P4, and the total weight of purified particulate matter is 12,000mg or more. The highest level of formaldehyde CCM with F is F4, corresponding to a total weight of purified formaldehyde of more than 1500mg.
CCM represents pollutant purification capacity; a high CADR alone does not imply that an air purifier is effective; only when the CCM is also high, does it demonstrate that the air purifier is not only fast purification efficiency, but also strong purification capacity, and the longer the life of the filter. Energy efficiency rating index: It refers to the ratio of CADR to rated power, which is the standard for power consumption. For particulate matter purification, a value of 2 indicates a qualified level, a value of 5 indicates a high efficiency level, and a value of 0.5 indicates a qualified level, a value of 1 indicates a high efficiency level for formaldehyde and other purification.
Therefore, for this review, Tianyi Home Appliance discovered the AirProce Air Purifier AI-700 upgrade model that can provide solutions for dealing with indoor formaldehyde and other gaseous pollutants, as a series of AirProce’s professional treatment of gaseous pollutants, it has a heavy 9.4 kg filter material and large air volume to ensure that the adsorption speed exceeds the CADR value. Let’s see how it turns out in the end.
So, can the AirProce Air Purifier AI-700 upgrade model effectively purify indoor air, and how effective is it? Let’s take a look at the first chapter of the review!
The experimental environment is a special transparent plexiglass test chamber (80mm*100mm*160mm) with an actual test space of approximately 2 cubic meters.
We will make the box filled with PM2.5, large particles of smoke through the cigarette lighter in the center of the box, turn on the cigarette lighter, about 4 minutes after the glass box filled with smoke, when a cigarette burned out, we measured the internal PM2.5 straight up, reaching the state of the explosive table.
At this point, we activate the purification mode via the cell phone APP and set the wind speed to 6 gears; the smoke in the box quickly dissipated, and the PM2.5 value detected by the testing instrument dropped to 0.
The graph below depicts the PM2.5 purification process that we documented.
