Talk about the difference and function between air purifier and new fan.

Let's focus on the difference between fresh air system and air purifier.

First of all, we should make clear the main difference between them: the air purifier is indoor air circulation filtration; The fresh air system is indoor and outdoor air circulation filtration.

Secondly, it should be clear that what we need more is filtered fresh air, rather than filtered air repeatedly.

Now let me explain why we should choose fresh air instead of air purifier:

1, the air purifier needs to be used in a relatively closed space, and the use of windows will reduce the effect;

2. Repeatedly filtered indoor air is indeed clean air, but the most obvious disadvantage is that the concentration of carbon dioxide will continue to rise, making us feel suffocated and unable to breathe.

3. The most basic function of the new fan (fresh air system) is ventilation-introducing fresh outdoor air; And there are filters, which can filter the outdoor air and introduce it into the room-keep the indoor air clean.

Summary: If you really want to achieve a good indoor air environment, it is suggested that you can consider installing a new negative ion fan and choose a negative ion purifier to assist. Small particle size negative ions have the functions of reducing smoke and dust, sterilization and disinfection, and are also good for human health.
