What is an air purifier？
A brief introduction to the air purifier
Air purifiers are generally made of filters, filters, motors, built-in fan motor filters filters, and other elements of the air cycle inhalation, through a specific cartridge on the adsorption of pollutants, decomposition, and purification, while some will also release ions, to achieve the purpose of the whole house cycle purification.
Role of air purifier
Air purifiers as a new type of household appliance, with regulation of stability, automatic detection of smoke, filtering dust, eliminating odors and harmful gases, double sterilization, release of negative ions, and other functions.
The micro-fan in the conventional type purifier makes the indoor air circulate. The polluted air will be removed or adsorbed by various pollutants after passing through the air filter inside the machine. Then through the anion generator installed in the air outlet, the air will be ionized continuously to produce a large number of negative ions, which will be sent out by the breeze to form the anion airflow, so as to achieve the purpose of cleaning and purifying the air.
Product Classification
Although the name, type, and function of the air purifier claimed in the market are not the same, tracing back to the working principle of air purifiers, it is roughly divided into three types: passive, active, and active-passive hybrid mode.
Pros and Cons of Air Purifiers
Advantages of air purifiers
Filter out harmful substances in the air:
The air contains a large number of particles and harmful substances, which have a greater impact on people with weakened or sick bodies.
Pollen, dust, pet dander, and the invisible PM10 and PM2.5 can all be blocked. Air purifiers can effectively filter them out through purification filters, reducing the harm to the human body.
Remove odors and harmful gases:
Some air purifiers are equipped with activated carbon or adsorption layers, which can effectively remove indoor odors and harmful gases, such as formaldehyde, benzene, ammonia, and other harmful gases.
Bacteria and aldehyde removal:
Some high-end air purifiers are also equipped with ultraviolet light or biocidal activated carbon filters to remove airborne bacteria, viruses, and other pathogens, to ensure that the indoor environment is hygienic and healthy.
Disadvantages of air purifiers
Noise problem:
As the air purifier needs to circulate the air through the fan during the working process, it will produce a certain noise, especially when it is more obvious in the high-speed gear.
Low energy efficiency:
Some air purifiers have relatively high energy consumption, which increases the burden of household electricity consumption and does not conform to the concept of energy saving and environmental protection.
Filter replacement cost:
The air purifier filter replacement cycle is more frequent, and the price of the filter is relatively high, which will increase the economic burden for some users with limited financial conditions.

Good filter material (such as HEPA high-density filter material) adsorption 0.3-micron pollutants above the ability of up to 99.9% or more; if the indoor smoke pollution is heavy, you can choose to remove the dust effect of the better air purifier.
3. Cleaning, maintenance convenience
Filter cleaning and replacement of the purification effect on the role of obvious. In the purchase of air purifiers, one must also pay attention to the product cleaning, and maintenance convenience. Specifically: first look at the base of the air purifier is removable because the removable base is simpler to clean; secondly, we must also pay attention to the replacement of the filter operation is convenient.
4. Silent effect
Air purifier silent performance is also a very key indicator, high-grade noise value should be less than 55 decibels, low-grade should be less than 30 decibels, high-grade (strong gear) is generally dirty indoor air when open, usually open strong gear ten minutes later, indoor air quality will be significantly improved; low-grade basically open, if the purifier has a noise, sleep will certainly be affected. Do not just focus on the noise indicators on the product manual when shopping, it is best to personally try and experience the quiet ability of the product.
