Air pollution only PM2.5? Buy empty need to pay attention to this point

Although the heating season has not yet officially arrived, air quality has begun to worry, and soon, the air quality problem will become the focus of attention, PM2.5 index will be Become the number that must be understood every day.Every year to this time, can remove PM2.5 air purifier sales growth, but now troubled by our air quality problem is not just PM2.5.

PM2.5 major hazards

PM2.5 refers to the particles in the atmosphere less than or equal to 2.5 microns in diameter, according to the particle aerodynamics, also known as the particles into the lungs, because the particle size is small, rich in a large number of toxic substances and stay in the atmosphere Relatively long, distant transmission distance and other factors, the human health is no small threat.

PM2.5 is the main source of industrial production and automobile exhaust emissions, they are in the window ventilation or through the doors and windows gap can easily enter the room, but even without their presence, the same indoor there are a variety of harmful substances:

1, formaldehyde

Formaldehyde is the most harmful pollutants in the room, its main source is a variety of interior decoration materials, including paint, paint, man-made sheet, etc., even after several months of renovation ventilation, formaldehyde is still stubborn, because it Will continue to release 3 - 5 years or even up to ten years, the harm on formaldehyde here is no longer described in detail.

2, common bacteria and viruses

Bacteria and viruses can be attached to the dust in the air particle diameter of less than 5 microns, people through speaking, coughing, sneezing and other behavior is easy to mouth, throat, trachea, lung pathogenic microorganisms through the air to others, There is a potential threat.

3, all kinds of smell

There are many kinds of smell, including cigarettes, kitchen odor, musty, bathroom odor, pet smell, etc., for a long time to stay in such an environment may not feel, but they do exist, if the home to the guests, these smell It is easy to leave a bad impression.

Because the air pollutants not only PM2.5, so in order to deal with indoor air pollution to buy the purifier can not just look at its PM2.5 removal capacity, in addition to formaldehyde, odor removal, sterilization and other functions should also be taken into account, the air to achieve Comprehensive purification, such as Sharp's unique net ion group technology, which allows the purifier in the removal of PM2.5 and formaldehyde at the same time on bacteria, viruses, odor, static also have a good ability to remove.

Sharp's unique net ion group technology

Sharp's net ion group technology is based on the water molecules and oxygen in the air as the material, by applying positive and negative high voltage to produce positive and negative ions, compared to negative ions, ultraviolet, ozone, photocatalyst and other means of sterilization, positive ions + As well as sterilization are higher, but also for the human body will not have a negative impact. Positive ions + negative ions can be attached to the air in the floating bacteria, viruses and other surfaces, the formation of CH free radical decomposition into water and evaporation, its role Mainly reflected in the following three aspects.

1, bactericidal deodorant.Net ion group technology can be a good inhibition of allergen substances, planktonic virus, floating bacteria, deodorant, remove the role of phytoplankton, which is mainly the use of CH free radical oxidation.

2, remove the static. Winter dry climate, and sometimes the body will accumulate a lot of static electricity, to cause a lot of trouble, can release the positive and negative ions of the two groups of ions to produce a neutral role.

3, the skin moisturizing. Surrounded by the net ion group 'water molecules' can be attached to the skin performance, the formation of an isolation layer, so it has the effect of moisturizing.

Sharp in 1987 launched the first air purifier products, has been 30 years of history, during this period has the purifier and clean ion group technology, humidification, intelligence, mosquito and other functions combined, has not only to Clean indoor air, but to enhance the quality of life to enhance the quality of such a cleaner products more in line with the people now the pursuit of quality of life.

For another major source of pollution - formaldehyde, it is removed by the purifier in addition to the formaldehyde filter.

Judge a purifier in addition to formaldehyde capacity can see its formaldehyde CADR value of this indicator. CADR refers to the clean air output ratio, the air purifier per unit of time the amount of clean air output, the greater the value that the better performance. (PM2.5) and gaseous pollutants (formaldehyde, etc.) of these two indicators of the CADR value, the general manufacturers have the particulate matter CADR value as a publicity focus, in fact, formaldehyde CADR Value is also an indicator that can not be ignored.

Sharp air purifier FP-CH70-W

Deodorization in addition to formaldehyde one filter can effectively remove formaldehyde

For example, this Sharp air purifier FP-CH70-W, the middle of the black layer of the filter is based on activated carbon, will be able to adsorb formaldehyde on the catalyst can play in addition to the role of formaldehyde in this machine formaldehyde CADR Is 196.5m3 / h, to meet the basic needs of aldehyde, other brands have a lot of models of formaldehyde CADR value is very low, usually simply can not play a great use.If you are just renovated house, you can buy those main in addition to formaldehyde Of the purifier products.

Said these just want to tell you that the air purifier can not just stare at PM2.5 this data, because now there are many air pollution sources at home, PM2.5 is only one of the other there are formaldehyde, bacteria, odor, etc. And so on, these are also in the scope of the purifier, so when the best choice in the purchase of cleaners like Sharp net ion group technology and other air purification capacity of the product, so breathing health is more assured.
