Air purifier or fresh fan, which purifies the air better

The purification principle of the new air is to transport the outdoor air purifier to the room and dilute the pollutants in the room to achieve the purification effect. The air purifier achieves the effect by circulating the air in the room. To learn more, check out the reviews.

It is recommended to install a negative ion fresh air fan.

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. Small particle size negative ions themselves have the effects of smoke and dust removal, sterilization and disinfection, and are also beneficial to human health.

The home air purifier is better than the fresh air system, which is a system that treats the outdoor air through purification technology to achieve fresh air that meets the health requirements and is sent to the indoor room. It is mainly composed of several parts, such as purification device, Shiwu fan, pipeline, tuyere, etc.

In terms of purification technology, compared with air purifiers, there is not much difference. It's just that the air purifier deals with the indoor air, but if the air purifier is used for a long time, the freshness of the indoor air, that is, the oxygen content, will not be enough, and the fresh air system can solve this problem.

Purifiers and fresh fans depend on each individual, but there are the following differences.

First, the principle of action is different.

The purifier is a single-room internal circulation purification, which only adsorbs and stores the pollutants in the air in the room, and cannot introduce fresh air, which improves the indoor oxygen content and reduces indoor carbon dioxide. The fresh air system is to filter the harmful part of the outdoor fresh air, and continuously input the fresh oxygen-rich air into the room, and at the same time discharge the dirty air in the house.

Second, the scope of action is different.

The purifier can generally only purify a single room, while the fresh air system can work on the whole room, and the purification area should be large.

Third, the effect of aldehyde removal is different.

The most effective means to remove formaldehyde is to open windows for ventilation, and purifiers are to clean formaldehyde by adsorption, and the effect will get worse and worse over time. The Rolet fresh air system dilutes indoor formaldehyde by exchanging air, and as long as the air exchange rate exceeds the formaldehyde release rate, the indoor air quality can be guaranteed.

If you live in a place where the outdoor environment is very poor and you can't open the windows 300 days a year, it is indeed better to choose fresh air because it can circulate outdoor air. Although an air purifier can solve the problem of indoor air circulation, if you don't open the window, you are still circulating "old air" after all.

However, if the outdoor air quality in the area where you live is not so bad, and you just need to solve the problem of indoor air circulation, then an air purifier will be a better choice. Because it's professional enough! In addition to indoor formaldehyde in my new house, I choose a professional air purifier called B-Mola.

It can literally decompose formaldehyde into water and carbon dioxide, and it is said that more than 70 hospitals in China have used the same technology to treat exhaust gases. This is much more specialized than most methods that only rely on activated carbon adsorption filtration

Air purifiers, also known as air cleaners, air purifiers, etc., are mainly used to filter, adsorb or decompose various air pollutants (provided that they do not contain formaldehyde). Products that improve air cleanliness. The fan in the purifier is the indoor air circulation, and the polluted air passes through the air filter in the machine to filter and adsorb various pollutants, and then sends it out through the air outlet, so as to achieve the purpose of purifying the air.

However, it is limited to remove harmful gases from the room. The effect is related to the size of the room to be purified, the area of the filter screen of the purifier and the air volume. Due to cost and volume, the actual use effect is very limited, and the filtration efficiency gradually decreases over time, so it is difficult to achieve the desired effect.

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. <>
