The Garconia fresh fan and the Xiaomi air purifier are good, let s be specific.

Xiaomi air purifier can only purify the indoor air by repeated circulation, and can only solve the indoor air in a short time, and the air quality will get worse and worse in the long run. Indoor air is not circulated, no matter how sterilization feels that the air is still very dirty, Jaconia fresh air can make the outdoor air filter and adsorption all day long, directly to the indoor delivery of clean air, formaldehyde, toluene, and carbon dioxide we exhale can be removed, the two are not the same level...

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

Domestic air purifiers are also Yadu, Midea, Xiaomi, these brands.

Yadu's is better.

Xiaomi's purification capacity was really okay at the beginning, but the purification ability was very poor later, and the noise was quite loud during use.

But at the end of September this year, I bought a Yadu double-faced air purifier, which is particularly cost-effective, and you will find that the user experience is particularly strong in the process of use, and the purification ability of particulate matter and formaldehyde is particularly strong.

What's more, I really like the design of the room, which goes well with the decoration of the room. You can use the Yadu Cloud Life app to remotely control the air purifier when you are outside, and check the air quality at home in a timely and efficient manner.
