What is a fresh air system, is it better to have a fresh air system or an air purifier

The fresh air system needs to introduce fresh outdoor air into the room through mechanical power, with inlet air and exhaust air, which is divided into ducted installation and ductless installation. Considering the market demand, most of the fresh air systems are now equipped with high-efficiency filters.

Air Purifier vs Fresh Air System——

There is overlap in the market demand of air purifiers and fresh air systems, but there is no contradiction between the two products to meet the different needs of users.

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

If you install a fresh air system in your home, you can purify the indoor air. What are the differences between a fresh air system and an air purifier? PChouse will take you to find out.

1. The method of air purification.

The air purifier is purified by the method of internal circulation adsorption filtration, which can directly filter the particles in the air like a sieve, and then quickly and effectively produce clean air.

The fresh air system uses the method of external circulation and ventilation to complete the purification, inhale the clean air and then discharge the turbid air in the room. The ventilation of the fresh air system is orderly ventilation, through the planning of the air outlet and the air inlet, forming a point-to-point ventilation route, planning the air inlet in the bed, sofa, dining table and other places where the owner needs fresh air the most, and planning the return air outlet in the toilet and kitchen, so that the turbid air can be quickly discharged after the occurrence.

2. Install and use the environment.

The air purifier is flexible and can be moved at will; The fresh air system is based on the decoration status of the room, and selects the ceiling-type full heat exchange fresh air, or the wall-mounted fresh air with holes in the wall.

3. Air purification efficiency.

Air purifiers can quickly purify indoor air, but they have limitations in their use and are more suitable for solo rooms.

The fresh air system can improve the air environment of the whole house, but the efficiency of transporting fresh air into the room and thoroughly improving the air of the whole house is relatively slow, so when selecting the fresh air system, it is necessary to select the system with suitable air volume according to the size of the room.

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.

1. The appearance is different.

In terms of appearance, although the two are somewhat similar, there are still certain differences, for example: there is a hole behind the new fan for inhaling outside air, while the air purifier does not have such a hole.

2. The functions are different.

From a functional point of view, many fresh fans have a heating function, which can heat the indoor air to the right temperature, while air purifiers do not have such a function.

3. The principle is different.

In principle, the fresh air fan has an independent air handling system, which can filter the fresh air from the outside and send it into the room through the pipe, and at the same time exhaust the dirty air with low oxygen content from the outside. In addition, the fresh air without alarm can also discharge the harmful gases that are not released after the decoration to ensure that people's bodies are not damaged, and can also regulate the indoor humidity to avoid mold on furniture and clothes. The purifier can only adsorb, decompose or convert the harmful substances in the air in the indoor air, and then discharge the harmful substances in the room through internal circulation.

But it also has an obvious drawback, that is, it only circulates indoors, and oxygen is constantly being consumed.

4. Noise and energy consumption are different.

From the perspective of noise and energy consumption, the noise and energy consumption of the new fan are larger than those of the purifier, but they are detected within the controllable range and will not affect people's rest.

The fresh air purifier can deliver fresh and clean air to the room after the 24-hour outdoor air is filtered with high efficiency and adsorbs harmful substances in the air. Regardless of indoor formaldehyde, toluene, xylene, and carbon dioxide exhaled by our human body, we all 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 in the indoor air, dust, etc., but the room must be sealed in Luzhou, 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 for a short time, and cannot completely improve the air quality of our living space. And the fresh air system can improve the air quality.

Nowadays, many homes are equipped with air purifiers, but it is not recommended to use air purifiers instead of open windows for ventilation, proper ventilation is better, in addition, fresh air systems are also very popular now, so, is it better to use fresh air systems or air purifiers? I'll introduce you below.

Can an air purifier be turned on instead of opening a window for ventilation?

Most air purifiers have the main function of filtering pollen, formaldehyde and other pollutants in the air, but there is no way to make oxygen and remove carbon dioxide. If you do not open the windows indoors for a long time, the oxygen and carbon dioxide levels in the house will change, which may lead to physical discomfort. It is recommended to open the windows properly when the air quality outside the house is excellent to ensure enough fresh air**.

Is it good to open the windows to ventilate all day and night.

Not very good.

Although it is beneficial to open the windows properly, if the windows are left open for ventilation all day long, then it will also cause the indoor temperature to be too low, and it is easy for the human body to have cold symptoms due to cold.

And once the outdoor air is polluted, it will affect the quality of the indoor air if the windows are opened all day and night for ventilation, so it is not recommended to open the windows at this time, if you feel that the air is too stuffy, then it is recommended to choose an air purifier to purify the air.

It is better to use a fresh air system or an air purifier.

1. Cost. Now the most popular household ** pipe fresh air system, the cost will be relatively high, generally in the range of 10,000 to tens of thousands. For the average family, the cost may be a bit high.

However, in the case of air purifiers, the cost will be relatively low. Generally around 1000-5000. If you don't have the budget, an air purifier is recommended.

Of course, there are many types of fresh air systems, and the same is true for air purifiers. However, it is generally the fresh air system ** high.

2. Functions and effects.

There is a difference between the principle of the fresh air system and the air purifier, the principle of the fresh air system is mainly to replace the outdoor air with the indoor air, discharge the indoor air outdoor, and then pump the outdoor air into the room to form an air circulation. An air purifier, on the other hand, purifies the indoor air.

Therefore, if you have a good ventilation effect and the orientation is correct when you open the windows in your home, you don't need a fresh air system. If the outdoor air is poor and the air pollution is severe, an air purifier is more recommended. If the outdoor air quality is very good, but the windows at home do not exchange air well, it is recommended to use a fresh air system.

3. Difficulty of installation.

The air purifier does not need to be installed, but the fresh air system needs to be installed, and the installation process is troublesome, generally before the decoration of the new house, the hard installation link, if it is a well-decorated house, it will be very troublesome to install the fresh air system. Of course, there are many kinds of fresh air systems, and some simple fresh air systems are less difficult to install, but the effect is certainly not so good.

If you find it difficult to install, it is recommended to choose an air purifier that does not require installation.

Personally, I think that if you don't consider the cost, the fresh air system is better.

The fresh air system is the external circulation of air, and the air entering the room is filtered, which not only has the advantages of opening the window, but also avoids the disadvantages of opening the window. It can reduce carbon and enrich oxygen.

The air purifier is the internal circulation of the air, it only filters the indoor air, we can't rely on it too much or pick a good time to open the window for ventilation, because it can't reduce carbon and enrich oxygen.

What the human body needs most for breathing is oxygen, and living in an oxygen-rich environment for a long time will improve the body's metabolism and immunity.

The fresh air system is better.

The fresh air system can comprehensively improve the poor indoor air environment, transport fresh air into the room, and completely improve the overall room, which may be slightly slower than the local improvement. When choosing a fresh air system, it is necessary to choose a suitable air volume system according to the specific room size, because products with large air volume will lead to an increase in cost, the air volume is too small, and the indoor purification effect cannot meet the requirements.

Advantages of the fresh air system:

1. The fresh air system can deliver fresh and clean air to the room after 24 hours of outdoor air filtration and effective adsorption of activated carbon, and the carbon dioxide exhaled by our human body needs frequent ventilation. Therefore, we need a fresh air system for efficient filtration and adsorption.

2. The air purifier can only circulate and purify the indoor air, and can purify the smoke, particulate matter, dust, etc. in the indoor air.

3. However, the room must be closed, 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 for a short time, and cannot completely improve the air quality of our living space.

4. The filter screen of the fresh air system does not need to be replaced for a long time, and the approximate use of the early skin limit is nearly 10 years, which mainly depends on the quality of the fan, so you should still choose the brand when purchasing the fresh air system. <>

In comparison, I am personally more optimistic about the fresh air system.

The fresh air system is more externally circulated.

The air outside the fan is filtered through the filter and sent to the room, and the indoor air is sent out of the exhaust duct to continuously replace the indoor air.

If you don't open the window, you can breathe fresh air.

The air purifier is an internal circulation, which can help us filter large particles such as animal hair, catkins, leaves, pollen, dust, second-hand smoke, that is, haze and other smaller particulate matter, and some can also adsorb gaseous substances, such as formaldehyde, toluene and other compounds.

Some of them also have a secondary negative ion system, which can increase the activity of the air, and then it is also more beneficial to people, it can promote metabolism, improve sleep, and refresh the mind.

It is recommended to use a fresh air system, which can deliver fresh and clean air to the room after absorbing harmful substances in the air after the outdoor air can be filtered for 24 hours. Regardless of indoor formaldehyde, toluene, xylene, and carbon dioxide exhaled by our human body, we need frequent ventilation. Our industrial waste, car exhaust, and dust in the air will enter the room through the air transmitted through the door, so we need a fresh air system for filtration and adsorption.

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.
