With the declining air quality in the modern world, air purifiers have gradually become a necessity for family life. But in the face of the many air purifiers on the market, it has generated a lot of questions, what is an air purifier? What are the types of air purifiers? What is the role? How do we buy a purifier? In the face of these problems, this editorial has a simple answer.
What is an air purifier？
air purifier
Air purifier, also known as air cleaner, or purifier, refers to the ability to adsorb, decompose, or transform a variety of air pollutants (generally including PM2.5, dust, pollen, odors, formaldehyde, and so on), to effectively improve the cleanliness of the air home appliances, mainly divided into domestic, commercial, industrial.
Working Principle of Air Purifier
Air purifier is mainly composed of a motor, fan, air filter, and other systems, its working principle is: that the motor and fan in the machine make indoor air circulation flow, polluted air through the air filter inside the machine after the removal of various pollutants or adsorption, the air is constantly ionized, producing a large number of negative ions, sent out by the micro-fan to form a negative ions airflow, to achieve the purpose of cleaning and purifying the air.
Air purifiers can solve problems
Natural air pollution, Pollen, Dust mites, Second-hand smoke, Formaldehyde
What does an air purifier do?
H3 filters small particles: Pollen, dust, pet dander, and those invisible PM10, and PM2.5, it can all help you block!
Eliminate toxic and harmful gases: formaldehyde, benzene, pesticides, etc., these invisible killers in the home environment, there is no place to hide in front of it.
Specializing in formaldehyde: the formaldehyde problem after the new house decoration is a big problem for many people. Air purifiers can not only adsorb formaldehyde but also decompose it so that you can live in the new home faster.
Neutralize odors: some air purifiers are equipped with materials such as activated carbon, which can adsorb and neutralize harmful gases and odors in the air, such as smoke, kitchen odors, pet odors, etc., so as to make the indoor air fresh and comfortable.
Why do we need air purifiers？
Which groups of people need air purifiers more
Mothers and babies with pets: mothers and babies are weaker, and pet hair, dander, and bacteria are hidden dangers. When choosing an home air purifier, look for one with UV disinfection technology, which is more suitable for mothers and babies. Select particulate matter CADR and CCM value is high, HEPA filter and other J should also be H12 or more, so as to ensure that the air is clean!
Decoration crowd: new home renovation, adhesives release formaldehyde is worrying. Select air purifiers, formaldehyde CADR and CCMz worth high, benzene and VOC parameters can not be less, it is recommended to choose the more appropriate to decompose formaldehyde.
Allergic people: allergic rhinitis, pollen allergy, or asthma, have to prevent dust, pollutants, and allergens. When choosing an air purifier, you need to have the function of removing allergens, picking particles with high CADR and CCM values, as well as HEPA cartridges, H12 or above with disinfection function. In this way, the air is clean and health is guaranteed.
Smoking family: second-hand smoke in harmful substances can be a lot, you have to choose to remove particulate pollution from the air purifier, and CADR and CCM value is high, but also have to look at the TVOC parameters because the second-hand smoke particles and TVOC pollution are very harmful (the higher the value of TVOC, the better the purification effect)
How to buy an air purifier？
1. CADR
CADR value refers to the purification efficiency index of the air purifier, divided into formaldehyde and particles. The higher the value, the faster the purification, and the more space applicable. But don’t blindly pursue the high value, according to the actual area to choose. This can save money and practical
Conversion formula reference: CADR value > maximum room area * 10
2. CCM
CCM value is the key to measuring the purification ability of air purifiers, representing the service life of the filter and the ability to carry pollutants.
CCM value is the key to measuring the air purifier’s purification capacity, which represents the service life of the filter and its ability to carry pollutants, such as J, P1 to P4 for particulate pollutants and F1 to F4 for formaldehyde pollutants, of which P4 and F4 are the highest levels.
(According to the new national standard and other J standard divisions – the larger the number, the higher the grade)
3. Filter material
The filter is the core of the air purifier, but also the key. The general air purifier filter is mainly divided into three parts: primary filter, HEPA filter, and activated carbon filter.
Primary filter: mainly filter dust, hair, and other large particles of pollution, generally as the first layer of the filter purifier.
HEPA filter: HEPA filter air purifier H10-H13 level optional, compared to the primary filter can filter small pollution, household and other J general H11 or more on the line!
Activated carbon filter: there are many kinds of carbon folder steps, granular columnar charcoal, carbon brick, sticky charcoal preferred charcoal brick
4. Filter structure
Tower structure: tower air purifier is used in J independent filters, commonly used for more than 10,000 purification structures, this purification method is sufficiently solid materials, filtering more layers
5. Vertical structure
This structure is currently on the market to use more, vertical air purifiers using a composite filtration system, the advantages of this structure of the purifier is smaller and easy to move, but the relative air ducts are shorter, the filter layer J is generally between 1-3
6. Aldehyde removal technology
Essentially all air purifiers have the ability to aldehyde, but for formaldehyde treatment, only adsorption rather than decomposition! Adsorption of formaldehyde will have the problem of secondary pollution, so give preference to air purifiers that can decompose formaldehyde. Select the curing decomposition of aldehyde + aldehyde dissolution molecular sieve, which can firmly adsorption of formaldehyde and decomposition into harmless carbon dioxide and water, and will not cause secondary pollution!
7. Bacteria removal methods
Bacteria removal methods and comprehensive of course, now popular ozone, plasma, and UVC ultraviolet light these three ways. UVC ultraviolet disinfection has to recognize the UVC lamp beads passive purification method is good, so when you choose an air purifier, it is best to choose a plasma function.
8. Noise
Generally, the lowest gear noise should be controlled below 35dB so that the children’s room will not be noisy when the baby sleeping!
Air purifier tips
1. Placement: the placement should be well chosen, placed in the middle of the room or 30 centimeters away from the wall, so that the air intake is sufficient. Put in the wrong place, dust, and pollutants can affect the life of the purifier.
2. Timing for core: filter element should be changed regularly, generally 6-12 months should be changed once, otherwise the effect will be discounted.
3. Humidifier: do not use a humidifier, the humidifier will make the air damp, and the cartridge easily removes moisture and bacteria, resulting in secondary pollution.
4. Do not open the window: do not open the window when using it, opening the window will let the outdoor pollutants come in, aggravating the burden of the purifier.
5. Electricity safety: remember to cut off the power supply when not in use for a long time, and try to avoid babies close to the process of safe use.
Breathing health starts with choosing a proper air purifier. While enjoying modern life, don’t forget to give yourself and your family a cleaner breathing environment. That’s all for this issue, see you next time!
