Why is it said that the fresh air system and air purifier are not suitable for negative ion technolo

Negative ion technology has been discovered and used as early as the last century, but the technical limitations, while producing negative ions, will produce a concentration of ozone that is not low, the excessive ozone smell is very terrible, and the harm to the human body is also very great, so the negative ion technology once fell into a low ebb.

Negative ion technology is now more and more advanced, there is already a negative ion new fan, and it is developed by Tsinghua University, small particle size negative ion technology, low voltage, long migration distance, high activity, and no ozone production.

1. The negative ions of most air purifiers are ordinary negative ions, at most they are a little purifying effect, the smaller the particle size of the negative ions, the higher the activity, the farther the migration distance, the better the purification effect, and can directly enter the human body (well documented, not explained here).

2. Simply speaking, the generation of negative ions, no matter which way is used, requires high-voltage discharge, the smaller the particle size, the higher the required voltage, and the high voltage will have an electrostatic reaction, and at the same time will produce ozone.

1) The hazards of high-voltage discharge: affecting electrical appliances (such as screen blurring, mobile phone answering ** interference, etc.); Harmful to the human body (such as friends with pacemakers, will make the pacemaker arrest, very dangerous!) ）

2) The harm of ozone: ozone can be sterilized and disinfected, but exceeding the standard will affect human health. Some ionizers will smell of rotten eggs when used, which means that the ozone produced exceeds the standard.

Therefore, negative ions are generally only an auxiliary role, not all electrical appliances have, the larger the electrical appliances most of them do not have negative ions, and small electrical appliances have negative ion function is also more common.

Now Tsinghua University's small particle size negative ion technology has come out, which solves this problem, the voltage can be controlled at a few hundred volts to produce a high concentration of small particle size negative ions, and it is also combined with air purifiers and fresh fans to benefit the public, so that every family can enjoy the healthy air brought by small particle size negative ions.

Choosing a fresh air system? It purifies the air and makes it comfortable for people to breathe for the following reasons:

Choose a fresh air system to keep the fresh air indoors 24 hours a day without opening the windows. The indoor air is no longer polluted, ensuring the function of ventilation and ventilation, and meeting the health needs of the human body.

The fresh air system can also discharge the bad indoor air, such as oil smoke odor, carbon dioxide, smoke smell, bacteria, formaldehyde, etc., into the fresh air after filtration and purification, so as to avoid a large amount of dust and harmful grinding and collapsing substances brought by opening the window, so as to achieve the purpose of replacing and purifying the indoor air. The heat and cold of the exhaust dirty air are retained and transferred to the fresh air that enters the room. The Rolet fresh air system sends the outdoor air into the room through coarse filtration, medium filtration, H13 high efficiency, UV lamp, negative ions, and exhaust air coarse filtration, purifying high blind and ozone-free.

Through heat, the temperature of the fresh air entering the room is close to the room temperature, which is energy-saving and comfortable.

When people use air conditioners indoors, they are generally reluctant to open windows for ventilation for energy saving or comfort reasons, which will lead to a decrease in indoor air quality. Choose a fresh air system with heat exchange function, even if the windows are not opened all year round, it can maintain good indoor air quality, creating a fresh, comfortable and healthy indoor space for you.

Because the fresh air system is cost-effective, the effect is good, and the effect is good.

The air purifier is an internal circulation system, simply put, it is to filter the indoor air over and over again, the international standard is to filter at least 5 times per hour, and can solve the problems of harmful particles, harmful gases, bacteria and other problems through a variety of different technologies, but because it is an internal continuous circulation can not solve the problem of oxygen content and carbon dioxide concentration.

The fresh air system is mainly to send fresh air to the room and discharge the dirty gas in the room. Combined with the four problems mentioned above, the fresh air system can provide fresh air, solve the problem of oxygen content and carbon dioxide concentration, and theoretically solve the problem of harmful gases and harmful particles, but from a pragmatic point of view, the number of air changes generally taken by the household fresh air system in the design is 1 time, and the solution ability is definitely not as advantageous as the air purifier.

In this way, the fresh air system and the air purifier have their own advantages, and they can complement each other when combined. After consulting many industry experts and consulting relevant literature, everyone's opinion on creating high-quality indoor air quality is that the fresh air system and air purifier work better together.

Vollara is the creator of quality life, and Vollara is the world's top high-end purification equipment brand. Vollara purification equipment provides home air purifiers, car air purifiers, portable air purifiers and water purifiers for homes, shopping malls and other occasions. Lay a solid foundation for the health of you and your family, and create a comfortable and clean working and living environment!

First of all, it is necessary to clarify the main difference between the two: air purifiers are indoor air circulation filtration; The fresh air system is a circulation filter of indoor and outdoor air.

Second, it's important to make it clear that we need filtered fresh air more than filtered air that is circulated repeatedly.

Now let me explain why you should choose fresh air over an air purifier

1. The air purifier needs to be used in a relatively closed space, and the use of open windows will reduce the effect;

2. The indoor air that is repeatedly filtered is indeed clean air, but the most obvious disadvantage is that the carbon dioxide concentration will continue to rise, making us feel stuffy and unable to breathe.

3. The most basic function of the fresh air fan (fresh air system) is ventilation - the introduction of outdoor fresh air; There are also filters that filter the outside air and bring it indoors – keeping the air clean.

Summary: If you really want to achieve a good indoor air environment, it is recommended to consider installing a negative ion fresh fan and choosing a negative ion purifier to assist. Tsinghua University's small particle size negative ions themselves have the effect of smoke and dust removal, sterilization and disinfection, and are also beneficial to human health

The air purifier is a closed circulation of indoor air to filter harmful substances such as indoors, which cannot solve the problem of increased carbon dioxide content and low oxygen content faced by people in confined spaces. Through the exchange and purification of indoor air and outdoor air, and at the same time realize external circulation and internal circulation, it solves the comprehensive air problems of indoor particulate matter, formaldehyde, volatile organic compounds, bacteria, formaldehyde, carbon dioxide, oxygen, etc., so that the indoor air quality is maintained at a level that meets the World Health Organization (WHO) human health breathing standards.

There are three main differences.

1.Comfort

The fresh air system introduces fresh air into the room through ventilation and supplemental oxygen, thereby improving the comfort of the living space and reducing the content of pollutants in the air. The advantage is that there will be no mixing of fresh air and dirty air, and the noise is relatively low when used. The space of the fresh air system generally includes bedrooms, living rooms, etc., but each space needs to be installed with separate equipment.

Air purifiers can only circulate the indoor air and do not bring fresh air from the outside into the room, so their comfort is reduced compared to fresh air systems. In addition, some air purifiers are noisy and can easily affect people's sleep when they are used.

2.Conditions of Use

Both the fresh air system and the air purifier have their own applicable conditions, and the fresh air system is suitable for the living room that needs to be ventilated but it is inconvenient to open the window. However, although it can be ventilated, it needs to be designed as a whole in the decoration stage of the room, and the professional requirements for design and installation are high, and must be completed by professionals.

The air purifier is suitable for the living room that needs to purify the air in a short time, and has the advantages of multiple purchase channels, no need for professional construction and installation, and plug and play.

3.Cost of use

The initial installation cost of the fresh air system is high, and it needs to be designed and wired by professionals, and the cost is generally calculated according to the actual indoor use area, about 200 yuan per square meter, including design, construction and purchase of fans, pipes, accessories and other expenses. The ** of the online shopping fresh air system is similar to that of buying in a physical franchise store, and the ** will be lower.

The ** of air purifiers varies greatly according to different brands, ranging from a few hundred yuan to thousands of yuan per unit. Although it cannot be generalized, it is generally cheaper than the fresh air system.

First, from the perspective of working principle.

The function of the fresh air system is to purify the outdoor air and introduce it into the room, and at the same time discharge the indoor dirty air to the outdoors, so as to continuously complete the replacement of the indoor air; The air purifier relies on the fan to suck the indoor air into the machine and then release it into the room after filtration and purification, and the air is still the original air, but some pollutants in the air are removed.

Second, from the perspective of the filtration system.

The filtration system is divided into three types from the perspective of filtration, screen filtration (filtering large particles), adsorption (mass and volume determine adsorption capacity), decomposition (some chemical reaction occurs); From the perspective of filtration methods, it is divided into filter screen (primary and medium effect mainly filter large particles to improve the efficiency of the later filtration system), electrostatic dust collection (high-voltage static electricity sticks to small particles), HEPA activated carbon (adsorption), photocatalyst (nano-level titanium dioxide produces photocatalyst action under the action of light source, which can effectively decompose small particles, organic gases, viruses and germs, etc.), general air purifiers are three to five layers of filtration, two-layer filter screen plus activated carbon plus electrostatic dust collection, etc., The Haoting fresh air system has a six-layer filtration system, including electrostatic dust collection, HEPA filtration, photocatalyst and other filtration systems, and because the air purifier is small, its adsorption capacity is limited, and the filter element often needs to be replaced more frequently.

Third, from the point of view of the use effect.

1.The effective purification area of a fresh air system can reach 200 square meters, while the purification area of an air purifier is often no more than 20 square meters.

2.An air purifier can't solve the problem of excessive carbon dioxide when sleeping at night, while a fresh air system can solve this problem.

3.Air purifiers can't solve the problem of bacteria and viruses breeding caused by air conditioners, etc., and fresh air systems can solve this problem.

Therefore, there is still a big difference between the fresh air system and the air purifier, and the fresh air system is better than the air purifier in terms of functional attributes.

1. The air purifier is useful, mainly for indoor air circulation filtration, which can only be said to treat the symptoms but not the root cause.

2. It may cause indoor secondary pollution. Some of the filters have activated carbon for physical adsorption and some chemical decomposition of formaldehyde removal, which may cause secondary pollution.

3. If you use an air purifier, first of all, on the basis of abiding by the time of replacing the filter, see if you want to replace the filter in advance according to your indoor situation to avoid secondary pollution; Second, it is best to use the air purifier with doors and windows closed, otherwise it will reduce the purification effect; Thirdly, the purifier is mainly based on the CADR value to judge the applicable area, and based on the above, the purifier is mainly used in stages, or as an auxiliary product of Shenghuan fresh fan for indoor air treatment.

Summary: If you really want to achieve a good indoor air environment, it is recommended to focus on Shenghuan fresh fans, supplemented by air purifiers, and the new fans can meet the root causes, and the air purifiers can meet the standards in the short term.

To put it simply, the essential difference between an air purifier and a fresh air system is that the air purifier is an internal circulation, and the fresh air system is an external circulation.

If the weather is bad, we generally choose to close the doors and windows, open the indoor air purification equipment, at this time if the home is an air purifier, its working principle is to purify the air in the closed room, the indoor air through the built-in filter of the machine to purify and filter again and then release, to ensure that the indoor air quality is excellent, the disadvantage is that there is no fresh oxygen release, the family has been in this environment for a long time, although the air is reduced, but it will cause excessive carbon dioxide accumulation, lack of oxygen, not good for health.

The working principle of the new fan is to introduce the outdoor oxygen-filled air into the room after purification through the filter screen of the fresh fan itself, and at the same time discharge the indoor dirty air to the outside through the exhaust outlet of the fresh fan, which can form a fresh and clean oxygen circulation in the indoor confined space to meet the human body's demand for oxygen, and the air quality is clean and full of oxygen. Better fresh air also has the function of negative ions, and at the same time can release small particle size negative ions, which not only have the function of purifying the air, but also have a good auxiliary effect on the human body's muscles. Tmall Shangsheng Fresh Air is the technology used, which was jointly developed by Tsinghua University.

Depending on your specific needs, the air purifier is the internal circulation, and the fresh air system is the external circulation.

The fresh air purifier can deliver fresh and clean air to the room after 24-hour outdoor air can be filtered with high efficiency and adsorb harmful substances in the air. Regardless of indoor formaldehyde, toluene, xylene, and carbon dioxide drawn by our human body, we need frequent ventilation. Our industrial waste, car exhaust, and dust in the air will all enter the room through the air transmitted through the door, so we need a fresh air purifier to filter and adsorb.

The air purifier can only circulate and purify the indoor air, which can purify the smoke and particulate matter, dust, etc. in the indoor air, but the room must be sealed, and we all know that the carbon dioxide exhaled by the human body cannot be purified by the purifier, so the air purifier can only solve the indoor air in a short time, and cannot completely improve the air quality of our living space.
