As a comfortable home product, the fresh air system has gradually entered everyones daily life!The filter is the core of the fresh air system, and it is also the top priority of whether the fresh air system can play a role.Once the filter is "served", the air volume will be affected, resulting in insufficient indoor oxygen content, and the number of air replacement does not meet the national standard requirements.At the same time, filtration efficiency will also be greatly reduced.So how long does it take to replace the fresh air system filter?What are the consequences of not changing for a long time.
Early efficiency filter: The general cleaning cycle is 2-4 months, depending on the degree of air cleaning in the area.Filters can remove larger dust in a vacuum cleaner or in a direct cleaning method.
High-efficiency filter: H13-level filter, the service life is 4-6 months, depending on the degree of air cleaning in the area.PM2.5 purification efficiency> 99.9%. After the service life is over, it needs to be replaced to maintain its purification effect.
The consequences of not changing the filter for a long time
Decreased purification efficiency: The larger level of the fresh air system can reach H13, and the purification efficiency is as high as 99.95%.EssenceThe low indoor purification efficiency is not fresh and comfortable in the early stage.Each filter has the number of dust and particles that can be used indefinitely. It is impossible to use it indefinitely. It exceeds the tolerance range of the filter. The fresh air system is not completely purified. Many dust will also enter the room and breathe into the human body.
The air output becomes smaller: some users may have this feeling. After a period of use of the fresh air system, the air outlet will obviously feel the air outlet becomes smaller. Even if it drives to a larger gear, the air volume is obviously insufficient.I will feel that there are problems with fresh air system fan or power.But the fact is that the dust capacity of the filter has far exceeded the standard value, and this is the common reason that leads to the smaller air volume of the fresh air system.The filter is irregularly cleaned and dusty, and the permeability will deteriorate. The resistance of the fresh air through the filter is relatively large, and the air volume of the air outlet will be much smaller than the original.
Increasing noise: The filter is too long to change and it will cause noise to increase, especially to install the fresh air in the bedroom and the study room, which will be more obvious.When the sound of a new fan is louder than usual, you can first check whether the filter is too large, try to replace the filter to see if the situation has improved.
The above is the suggestion for changing the filter of the fresh air system. If you want to learn more about information, please pay more attention to us- ——
