The outer frame of the medium efficiency paper frame filter adopts a hard paper frame, which is made of non-woven chemical fiber cloth and folded into shape. It is low in price, light in weight, and has good universality to reduce operating costs. It has a compact structure and is commonly used for pre filtration in ventilation systems. It is also suitable for air conditioning ventilation systems that only require one filter.

The medium efficiency paper frame filter is mainly used to filter air particles of 5um or more in the air. It is mainly used for mid end filtration of air purification equipment to protect the end filtration and extend its service life. The paper frame filter is a disposable air filter, but generally manufacturers recommend replacing it every 3-6 months. For workshops with high dust production, it may need to be replaced every month. If we clean the air filter in a timely manner, can the service life of visible fly dust be extended? That's for sure. You can take out the paper frame filter screen at regular intervals, use a soft bristled brush to remove large particles of dust on the surface, wipe the machine body, and check if the air filter screen is intact and undamaged. If it is damaged, it needs to be replaced with a new filter screen immediately. Timely cleaning of surface stains can extend their service life, reduce replacement frequency, and lower operating costs.

Medium efficiency paper frame filters are commonly used for:

1. Initial filtration of commercial and industrial ventilation and air conditioning systems

2. Purification and filtration of general indoor ventilation systems

3. Filtration of household air conditioning purification equipment
