On hazy days, it is better to use an air purifier or a fresh air system in your home

From the point of view of purification technology, the fresh air system is to filter the outdoor air and then introduce it into the room to achieve the effect of air exchange, the air filtration capacity of the conventional fresh air fan is limited, even if the high efficiency filter is used in the fresh fan, when the outdoor concentration reaches more than 7 times of the indoor concentration, the opening of the fresh air fan is equivalent to continuously inputting the pollution source into the room, and the fresh air installation is too troublesome; The air purifier is plug-and-play, in terms of purification effect, the negative ions released by the negative ion purifier can be combined with the particulate pollutants in the air, condensed into a clump, and settled to the ground, which has a good haze removal effect. The fresh air system also needs to replace the filter screen regularly, pipe cleaning, etc., and the later maintenance is also very troublesome.

Personally, I think that good and bad are a false proposition. There is only a suitable fit and a bad fit.

My friend's home has been decorated, I feel that the haze is big, and I want to install a fresh air system, but after seeing the scene, the staff of the Royal Northam fresh air system pointed out that the fresh air system needs to go through the pipe and install, even if it is wall-mounted, it also involves the installation of vents.

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.

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.
