How to choose wall mounted fresh air fans and air purifiers?portable air purifier wholesale

　　In addition to air purifiers, a product called "wall mounted fresh air fans" has received great attention in the past two years because they are similar in price and have the effect of purifying air. Many consumers choose air purifiers or wall mounted fresh air fans to solve this problem.

　　For the urgent air quality issue, should everyone choose an air purifier or a wall mounted fresh air fan? So what are the specific differences between the two products? What is the cost-effectiveness ratio between the two?

　　There are various technologies and media in air purifiers that enable them to provide users with clean and safe air. Simply put, the core of an air purifier is just an indoor air filtration device, which can be simply understood as an electric fan with a filter cover in front of it.

　　The fresh air system can compensate for the shortcomings of natural ventilation. It continuously and uniformly purifies and filters outdoor air before introducing it indoors, while also discharging the dirty indoor air to the outside. When introducing outdoor air, a total heat exchanger is also used to balance the indoor temperature difference, so that the introduced indoor air will not be too cold or overheated, and the human body will feel more comfortable. The installation of wall mounted fresh air fans is simple and convenient, with no pipes. Two holes are made on the wall, one for air inlet and one for air outlet, which can be used in both pre and post decoration houses.

　　Air purifiers can only circulate and purify indoor air, and can purify smoke, particulate matter, dust, etc. in indoor air. But the room must be sealed, and we all know that the carbon dioxide and suspended formaldehyde exhaled by the human body cannot be purified by a purifier. Therefore, air purifiers can only solve indoor air problems in a short period of time and cannot completely improve the air quality of our living space. And the wall mounted fresh air fan can input fresh oxygen into the room. After turning it on, harmful substances in the air, such as bacteria, viruses, formaldehyde in decoration pollution, can be expelled. It is only responsible for individual area spaces, which is the same as wall mounted air conditioning. Therefore, for large family units that have already been decorated, if you want to choose a wall mounted fresh air system, you need to install multiple units in different rooms.
