All air purifiers have consumables, which are the filter elements inside. The suggestion in the instruction manual of the purifier is to replace it once every six months. Different types of filter elements have different prices. The most common filter element can only filter PM2.5 and PM 10, and its price is low. A better filter element can filter pollen and bacteria at a moderate price; The better one can filter formaldehyde and the price is higher.
If the filter element is not replaced, it will be covered with dust, which will not only have no filtering effect, but also cause secondary pollution to the air. Bacteria, dust and pollen hidden on the filter will return to the room. The same is true of in addition to formaldehyde filter element, in which activated carbon is added.
Activated carbon can adsorb formaldehyde, but it will be saturated one day. When activated carbon is saturated, it will stop absorbing formaldehyde. When the indoor formaldehyde content decreases (lower than that in activated carbon), the formaldehyde hidden in the filter will be released again and become a new pollution source.
Air purifier recommendation
1, Shule A 10
In the actual measurement process, the purification effect is the best. In just 8 minutes, a room with a VOC value of thousands can be purified to single digits, which can quickly make the air in the room and bedroom look brand-new. The bottom is also equipped with a four-corner universal pulley, which can be easily moved to the designated position by the user.
In addition, Shule's A 10 has reached the national disinfection and purification standard, has the qualification of "Xiao", has advanced technology and precise equipment, and can effectively disinfect and purify some household formaldehyde gas, infectious bacteria and PM2.5 particles invisible at home.
Dual-core BLDC dual motors can increase the air inlet/outlet area, purify the air with high horsepower, adsorb dust and improve the purification CADR value. As mentioned earlier, the higher the CADR value, the higher the purification efficiency, which means the better the air purification degree of the environment.
2、IAM KJ800F-M8
This design is very atmospheric. In the design of the air duct, it also adopts two-side simultaneous air intake purification similar to Shule, and the purification efficiency is twice that of the traditional single filter. Multi-depth filtration makes the purification step by step, from HEPA net to MHCC honeycomb carbon block to ultraviolet sterilization and finally negative ion purification, and natural air purification is more effective.
Ultraviolet lamp can effectively sterilize, and the sterilization rate reaches 99.99%. Negative ions can effectively combat tiny particles such as PM2.5. LED display makes indoor formaldehyde, PM2.5, temperature and humidity values more intuitive, and you can rest assured when you see them. Mobile App control and other functional configurations are very complete.
3、352 X86C
The exterior design of 352 X86C air purifier adopts tower structure, and its fan adopts ebmpapst imported from Germany, with a 5-year warranty. Seven-layer progressive filtration, each layer of purification structure has been scientifically and rigorously designed, which can achieve multiple purification for different pollutants, but in actual purification performance, the purification speed is slightly slow and the measured wind speed is also very general.
It takes the modified activated carbon with micropores as the carrier, which can strengthen the adsorption capacity of formaldehyde. Through the locking of activated carbon and the volatilization of trace water molecules with the flow of air, the purpose of decomposing and purifying formaldehyde is achieved, and the formaldehyde removal rate of 1 hour reaches 96.9%. At the same time, the LED screen displays real-time values such as temperature and humidity, PM2.5, formaldehyde, TVOC, etc., and users can see at a glance.
