About how air purifiers work, or more specifically, how they perceive poor air quality.What we use most is the particle sensor to work as an important part.Particle sensors are not the most exciting thing we can talk about, but they are an important part of the function of the new air purifier.
Simply put, it can sense the small particles in the air that are harmful to you. The technical term is "particulate matter", which varies in size from visible to unconscious inhalation into the lungs. An example of particulate matter is pollen or dust. When inhaled in high concentrations, it can drive your sinuses crazy and worse.
Particles are generally divided into two categories. The first is particles smaller than 2.5 microns, and the second is particles smaller than 10 microns. (a grain of sand is about 90 microns in diameter. )
Without further explanation of the technology, in essence, the sensor reads the air in its room.It then looks for allergens, chemicals, smoke and other irritants in the air that are above normal levels.
In the new air purifier, if the sensor indicates that the air is clean, the air purifier will continue to operate normally at the lowest setting.If the sensor shows an increase in the concentration of pollutants in the air (that is, you burn something in the oven and your dog takes his new friend home), it will speed up the fan to remove the pollutants in the air.The light ring on the air purifier indicates the level at which the air purifier is working to remove the viscous substances in the air.
Visual indicators work well when you are too busy to read sensors.So we need to design a visual function, which means that the color of each halo indicates something different.White light means the air is clean.Blue light means it senses pollution that shouldn't be there and is speeding up the fan.Purple means it's trying to get rid of the irritants.Pink indicates the most serious air pollution and the highest fan speed.
In the new air purifier particle sensor can tell you all about your home air quality.Whether you paint your living room all day long or the construction worker next door is already working, it can feel everything.Real high efficiency particulate air filter and active carbon pre filter lock all pollutants, so that the air you inhale is clean and healthy air.A small sensor does a big job.
