Central fresh air system VS air purifier advantages and disadvantages big competition!

The fresh air system can deliver fresh and clean air to the indoors after 24 hours of high-efficiency filtration and decomposition of harmful gases, regardless of formaldehyde, stupid, toluene, xylene, xenon, and carbon dioxide exhaled by our body. Frequent ventilation is required. Although the indoor air is 5-20 times of outdoor air pollution, our industrial waste, automobile exhaust, and dust in the air will enter the room through the door. So we need a fresh air system for efficient filtration and adsorption.

The air purifier purifies indoor air circulation (and does not introduce outdoor fresh air), and can purify smoke, particulate matter, dust, etc. in the indoor air. But we must have the room sealed, and we all know that the carbon dioxide exhaled by the human body and the indoor suspended formaldehyde can not be purified by the purifier, so the air purifier can only solve the indoor air in a short time, and can not completely improve the air in our living space. Fresh quality needs.

Advantages and disadvantages of the central fresh air system:

Advantages: not only can effectively remove formaldehyde, but also deodorization, dust removal, moisture removal and room temperature adjustment.

The central fresh air uses the pumped air to solve the oxygen content problem, uses heat exchange to solve the problem of energy loss during ventilation, and uses HEPA filtration to solve the problem of fresh air PM2.5 purification.

1. Deodorization function: Fresh air can quickly discharge the odor of discomfort caused by various reasons and create a comfortable environment.

2. Dust removal function: floating in the dust in the air, with many bacteria that are invisible to the naked eye, so it is necessary to drive away the dust in the living room and workplace to create a comfortable environment.

3, dehumidification function: the moisture in the room is not only from the bathroom, the human body and the burning appliances will also release water, and now, the building is more airtight, prone to warm rooms and other mold due to condensation, bed and wall are rotted The problem is that the ventilation fan often removes moisture from the room, which keeps the room and the person comfortable and healthy.

4, adjust the room temperature: summer night, use the ventilation fan to drive away the indoor air, replace the cool air outside, the whole heat exchange in winter to reduce the indoor temperature loss, improve the winter heating effect.

By continuously supplying air and exhausting air, the fresh air system can continuously discharge indoor polluted air including formaldehyde, and the outdoor air is continuously sent into the room after being cleaned, and the circulation is continuously operated, which can effectively remove indoor furniture and the like. formaldehyde. According to experts, the installation of the fresh air system is equivalent to installing a green "lung" in the house. It can ventilate the air 24 hours without opening the window, and continuously discharge the formaldehyde, benzene, ammonia and other volatiles in the room. Toxic gases to protect human health.

Disadvantages of the central fresh air: no function of the air purifier, can only solve the indoor air quality by ventilation.

Advantages and disadvantages of air purifiers:

advantage:

In addition to particulate matter: dust, yellow sand, dander, pollen is the cause of allergic diseases, eye diseases and skin diseases.

In addition to microbes: mites affect people's skin health. Harmful fungi such as aphids cause respiratory diseases.

Harmful bacteria: Influenza viruses, molds, and air conditioners contain bacteria that cause high fever, diarrhea, and pneumonia.

Harmful exhaust gases: Vehicles, industry, and cigarettes are the main causes of headaches, soreness, and dizziness.

Chemical substances: harmful chemicals such as formaldehyde, benzene, ammonia, sulfur, and carbon monoxide are the main causes of cancer.

In addition to odor: remove odors such as human body, life, industry, chemistry, pets.

Air purifier shortcomings:

1, can not solve the problem of oxygen content, you need to open the door and window regularly.

2, HEPA filter activated carbon and other consumables need to be replaced regularly, otherwise the effect is greatly reduced.

3, most of the air purifier can only solve a single confined space, can not achieve central purification treatment.

It is recommended that you purchase the air purification equipment with HEPA high efficiency filter. It is understood that HEPA membrane is an international standard product. The effect of filtering PM2.5 is 99.97%, which is very reliable. There is also a kind of water filtration which should be good but not commercialized; Activated carbon filtration (recognized effective and harmless) can be left. As for other so-called technologies: negative ion function (contaminants are easy to adhere to indoors, and the effect of solving particles is very limited, the sterilization effect is controversial). Ozone generation risk can be abandoned; electrostatic filtration (It is very likely that excessive ozone is produced) It is best not to use it; the catalyst technology is also controversial (the Japan Catalyst Technology Association itself said).

The new wind is good or the air purifier is good. This is a proposition that the benevolent sees the wise and sees wisdom. It is just that the angle of the problem and the point of view are different. Xiaobian certainly hopes that the combination and solution of "new air + air purifier", but the early stage The investment is indeed not small, the new wind has basically PASS for the friends who have already renovated, and there are indeed new winds in the decoration. You can also consider the wall-mounted fresh air (full heat exchanger). Friends who have not renovated can consider taking the central fresh air in one step. Install, and select the appropriate air purifier according to the use situation. Ok, I’ll talk about it here, I hope I can bring you some help!
