The dust in the indoor air is a certain amount, and it is easy to get it through the internal circulation of the air purifier, but the dust caused by the exchange of the window gap with the outside air is the variable. It is recommended to use a one-way wall-mounted fresh air blower, which is not only the original indoor Some dust will be diluted and discharged by the incoming clean air. At the same time, because the indoor air pressure is slightly stronger than the outdoor, it also resists the dirty air coming in from the gaps in the windows. This is usually called"micro positive pressure", although it is only slightly Ten Pa. I actually measured that my house has a fresh air blower turned on 24 hours a day. It is fine to wipe the table once every half a month, and it can indeed save a lot of cleaning fees.
The easiest way to check is to clean a window sill surface and check whether there is dust on the window sill two or three closed windows to know that there is a lot of air exchange between the window gaps and the outside world. The exchanged dust cannot be handled by the purifier. To treat the symptoms, it is necessary to consider the root cause. Not only can the dust be handled well when the windows are closed, the room must also keep the air fresh and not suffocated, but also take into account the fact that the window is closed. With the increase in the concentration of gaseous pollution in the decoration, on the whole, only new fans can solve such a lot of"small"problems.
