1. Purification effect: mainly depends on the purification efficiency of the filter material
The most important indicator for measuring the fresh air system is the purification efficiency, which is essential to ensure that the outdoor air introduced is clean and healthy. An excellent fresh air system can achieve a purification efficiency of at least 90% or more. The purification efficiency mainly depends on the material of the filters.
The filter materials on the market are mainly divided into two types: pure physical filtration and electrostatic adsorption. Pure physical filtration refers to using a filter, and the filtration efficiency mainly depends on the filtration level. At present, the highest is the H13 high-efficiency filter. Electrostatic adsorption filtration, also known as electrostatic dust collection, is a static electricity box that contains tungsten wires, usually placed in front of the air inlet of the fan. These two methods have their own advantages and disadvantages. Physical filtration is relatively thorough, but the filter needs to be replaced regularly; The filter element of electrostatic filtration can be reused for cleaning, but it may produce ozone.
If you are a person who values respiratory health very much and is also diligent, you can choose a physically filtration fresh air system. If you want to achieve a permanent solution, you can consider using an electrostatic adsorption fresh air fan.
2. Fresh air volume and noise: need to be considered in conjunction with actual residential area
The fresh air volume and noise are also core issues to consider when purchasing fresh air system. The air flow at the air outlet is not only related to the air volume of the fresh air machine itself, but also to the professionalism of the installation. Without considering the air volume loss caused by pipeline installation issues, we can consider the indoor area and the number of residents (reference number: 30m³/h per capita) when making a purchase.
The fresh air system inevitably generates certain noise when working, which directly affects the user experience of the fresh air system. Usually, the air volume of fresh air is directly proportional to the noise, and the maximum noise is around 40 dB in the highest gear. However, in actual use, it is not necessary to use the highest gear 24 hours a day, so the noise impact will be smaller and can be basically ignored.
