[Bestbuy618 Home Appliance Channel] There is a saying in the evaluation of air purifier products: “Air purifier is good, the cartridge accounts for half.” This demonstrates the importance of the cartridge for the air purifier. The air purifier’s purification principle is to pass polluted air through the cartridge, which will adsorb and decompose the harmful substances in the air. As a result, the cartridge directly determines the purification capacity of an air purifier; if the cartridge of an air purifier is not good, then the air volume and wind speed are meaningless.
Today, I will take you to decipher why the filter of a Houser air purifier can make it reach the medical grade purification level.
First, we open the cartridge compartment; keep in mind that the cartridge cannot be removed directly; instead, you must “slide to unlock” at the bottom of the cartridge bin to remove the cartridge.
The Houser air purifier’s filter is circular in shape. When compared to the traditional flat filter, the ring filter has a larger filtration area in the same space and a larger contact area with the air, allowing for more indoor air to be purified at the same time. The ring filter, on the other hand, has a more dense structure, higher filtration efficiency, and a longer service life.
The Houser air purifier’s filter element is a composite filter that combines an effective anti-bacterial filter, an HEPA filter of H13 level, and coconut shell activated carbon.
The green filter on the cartridge’s surface is an effective antibacterial filter; its surface is a layer of antibacterial fibers, which can perform sterilization, antibacterial, and initial filtration of larger particles in the air to extend the life of the internal filter.
The middle layer is an H13 HEPA filter, whose primary function is to filter fine particles of 0.3 microns in diameter from entering the human alveoli. The diagram above shows that the HEPA filter of H13 level does not have the highest removal rate, but the removal rate of the filter is not the higher the better, the removal rate of the filter is too high also means that the resistance of the filter is greater, the ventilation will be reduced, resulting in low purification efficiency. If a higher level filter is used, a stronger fan is required to ensure purification efficiency, which will produce more noise.
As shown in the chart above, the Houser air purifier can remove 99.9 percent of PM0.3 by relying on the H13 HEPA filter.
The HEPA filter, on the other hand, is incapable of removing volatile organic compounds such as formaldehyde, benzene, toluene, xylene, TVOC, and so on. At this point, the innermost layer of the coconut shell activated carbon filter enters the picture. Coconut shell activated carbon is a type of broken carbon with irregular particles that has been specially treated to increase the contact area between the activated carbon and the particles, resulting in high adsorption capacity and low resistance.
The volatile organic compounds in indoor air can be reduced by 97 percent after this layer of coconut shell activated carbon is purified. The cartridge length of the Houser air purifier is 36.6cm with a diameter of 23.1cm, which translates into a traditional flat filter with an area of roughly 2654.74cm2, or 0.27 The previous review’s air velocity of 7.34m/s (the wind velocity of strong mode is selected) can be roughly calculated to have 1.95m3 of air in contact with it per second for purification.
Take, for example, a room 80m long and 3m high; it only takes 124 seconds for the air purifier to purify all the air inside. Of course, this is only a theoretical value; the air purifier is circulating to purify the air and cannot immediately purify the air in the distance. However, the purification power of the Houser air purifier is obvious.
The filter’s thickness is 3.64cm; generally speaking, the thicker the filter represents, the more air is in contact with the filter, the more contact area, the more contact area, the better the air will be purified. A thicker filter, on the other hand, will impede wind speed, affecting airflow and reducing purification efficiency. The filter thickness is about 3-6cm is more appropriate, this thickness range of the filter in the purification efficiency, purification effect, and noise to achieve a balance between. The cartridge weighs 1.68kg, which means that the material used in the cartridge is very solid, the solidity of the material used in the cartridge is related to the service life of the filter, normally the heavier the filter, the longer the service life.
1.68kg is still a good filter, making it easier for users to move the air purifier while also ensuring the filter’s service life.
Summary: The Houser air purifier cartridge employs a triple composite filter that not only effectively removes particulates and VOCs, but also bacteria and inhibits bacteria; the thickness is moderate, achieving a balance between purification efficiency, purification quality, and noise; and the solid material ensures its service life. As a result, it is not a boast that the Houser air purifier can achieve medical grade air purification; it can indeed remove more than 99.9% of PM2.5 and PM0.3, as well as 97 percent of volatile organic compounds.
