Is an air purifier useful? Comparison of filtering effect between air purifier and mask

Nowadays, the epidemic situation is so severe that we need to keep ventilation indoors. This is an important part of doing well in epidemic prevention at home. If we can have a good air purifier at home, it would be better. But we all have such questions. Is it useful for epidemic virus to buy an air purifier at home?

Who is more effective, air purifier or mask?
According to the analysis of the transmission way of virus, respirator prevention is very effective, but most people don’t wear masks if they don’t go out, so back to today’s unfolding topic, how about the filtration efficiency of air purifier? Is it better than masks?
mask

In terms of purification principles, the answer is yes. For example, air purifiers with H11 and H13 level HEPA filters can filter 99.5% and 99.97% of particulate matter less than or equal to 0.3 microns. This filtering level is definitely higher than N95 masks, because N95 masks are greater than or equal to 0.3 The micron particle filtration efficiency is 95%.
A3bHowever, in practical situations, is an air purifier more effective than a mask? The answer may vary greatly depending on the situation. First of all, the index of filtration efficiency refers to the filter, but the filter requires the air purifier to function. That is, the internal fan, and the exact point is CADR (the amount of clean air per cubic meter per hour). We see that there are too many products to blindly render the filter level regardless of CADR, but look at CADR regardless of the filter. Indicators such as lifespan, energy efficiency level, and noise are also undesirable.

How to use air purifiers properly during an epidemic?
  1. Placed correctly
The location of the purifier is somewhat particular. If conditions permit, it is best to place it in the center of the room, especially the purifier cannot be placed against the wall, which will greatly reduce the purification effect. For placement, a certain distance from the wall is required to ensure that the air flowing in and out of the machine is smooth and helps the indoor air circulation.
Do not put the air purifier with the water container or the humidifier together to prevent water vapor from entering the air purifier, causing damage to the machine or causing an electric shock.
2, timely open window ventilation
In fact, the air purifier should be carried out in a relatively closed space during normal work. At this time, often opening doors and windows will increase the pressure of the air purifier and reduce the purification effect. The user can open the window for ventilation when going out, or proper ventilation when the outdoor air is good.
3.Plug the power supply correctly
If we do not use the air purifier for a long time, we must unplug the power supply. When unplugging the power supply, we must hold the plug. Do not pull the power cord to unplug the plug. Otherwise, it may cause power damage or electric shock.

The importance of texture with vision inspection technology

If a review through  visual inspection  is needed to be effective, the most sophisticated   equipment that exists should be available.
