More and more serious air pollution is endangering human health, at this time you need an air purifier to improve air quality.However, there are so many air purifiers on the market, how to choose a good quality? Here are some indicators:
CARD refers to the ratio of air purifier output to clean air as measured by the American home appliance manufacturers association (AHAM) according to strict test standards. The higher the value, the higher the purification efficiency of the purifier. Guanglei’s air purifier has a CADR value of 420 m3/h, which can clean the air quickly.
2.HEPA Filter & Honeycomb Active Carbon Filter
The filter device is the core of the purifier, Guanglei air purifier mainly uses HEPA filter and honeycomb active carbon filter.
Activated carbon filter can effectively absorb formaldehyde, odor, second-hand smoke and other organic gases and odorous gases of various gases. The waste gas can be discharged directly after absorption concentration and purification. Activated carbon has a service life, absorption saturation will lose function, need to be replaced. But don’t worry, the air purifier of guanglei has a service life of 2000 hours, which will remind you when the value is reached, so don’t worry about the ineffective work of the filter.
The HEPA filter can effectively filtrate hair, pollen, dust and other large particles in the air. HEPA filters are classified into different levels. Filters up to the HEPA standard can filter PM2.5, which is particles with a diameter of 2.5 microns or less in the air. The higher the filter level is, the higher the purification efficiency will be, but the resistance will also increase, which will lead to the reduction of air volume. The air purifier of guanglei use H11 HEPA filter, which can remove rate up to 99%, but does not affect the air volume.
Negative ions are abundant in our natural environments such as forests, waterfalls, mountains and beaches, Negative ions are useful for enhancing the metabolism and homeostasis of the human body. effective in removing pollen,dust,mold spores and other harmful particles from the air. People need about 13 billion negative ions per day, while our homes, offices, entertainment venues and other environments can only provide about 1-2 billion, which is often prone to respiratory diseases such as pneumonia and tracheitis. The negative ions of Guanglei’s air purifier is up to 2*10^7pcs/cm3 and are able to improve mood.
When CADR goes up, the fan inside the machine must rev up, the noise goes up. So the noise is related to CADR. A good air purifier has a minimum working noise of 30-40db and a maximum working noise of no more than 70dB.
Air purifiers noise standards:
150 m³/h <CADR≤300m³/h，Noise≤61dB；
300h m³/h <CADR≤450m³/h，Noise≤66dB；
Guanglei air purifier noise standards:
Sleep mode, Noise≤35dB
Guanglei air purifier is the right choice for you.
