What happens if I don't replace my medium efficiency air filter?

Medium-efficiency air filters are used primarily in the ventilation system settings of central air-conditioning equipment, but also in the purification of hospitals, food, electronics, and other operations.
The medium-efficiency filter can be used in combination with the high-efficiency filter, as the pre-filter of the high-efficiency filter, which can reduce the load of the high-efficiency filter and can extend the life of the high-efficiency filter.

Medium efficiency filters are part of the F series of air filters, which are divided into two types: bag type and non-bag type.
The bag type includes F5, F6, F7, F8, and F9, while the non-bag type includes FB (plate type medium efficiency filter), FS (partition type medium efficiency filter), and FV (combined medium efficiency filter).
The main purpose is to remove dust particles above 0.5UM from the air by physical interception and to continuously purify the air.


The media components of an intermediate efficiency air filter are the color layer + efficiency layer + synthetic layer, of which the efficiency layer is the most important.
The efficiency layer is determined by the meltblown fabric.


Medium-efficiency filters are generally used in large air conditioners or central air conditioners in public places and are generally used in the majority of medium-efficiency bag filters.
In addition, several precautions should be taken when installing a medium-efficiency air filter, which is fire and water-resistant and is best used in combination with other primary filters.
It is more important to check and replace the medium efficiency filter regularly.
Generally speaking, the service life of a medium efficiency filter varies from 3 to 6 months and it seems quite important to check the filter and replace the filter media regularly, I believe many people know the importance of maintenance.


Air filters can be simply divided into primary air filters, intermediate filters, and high-efficiency air filters according to the efficiency of filtration.
The air filter itself is not repairable, if a breakage occurs the air filter is declared obsolete, so it should be cleaned and replaced regularly and carefully.
For different levels of air filters, different cleaning methods are used.
In general, the primary and intermediate efficiency filters should not be cleaned more than three times.
Air filter maintenance and care should be regularly and reasonably maintained, so that the service life can be extended.
Generally speaking, 3-6 months should be replaced once, the specific or according to the conditions and requirements of the environment for replacement.


The hazards of not replacing the medium efficiency air filter for a long time:


1. reduced air volume and insufficient cooling capacity;


2. The filter filtration efficiency decreases and fails to meet the purification requirements.


3. The system air resistance increases, and the operational energy consumption increases.
Wind resistance to a certain extent, will cause the filter bracket deformation, and damage the filter bracket.
