company news about Material of Washable Pre-Filter

The washable pre-filter can be made from different materials such as foam, mesh, and cotton. Foam pre-filters are commonly used in HVAC systems, while mesh and cotton pre-filters are commonly used in air purifiers. The washable pre-filter material should be selected based on its efficiency, durability, and cost-effectiveness.

Working Principle of Washable Pre-Filter

The working principle of the washable pre-filter is quite simple. When air passes through the filter mesh, large particles such as dust and pollen get trapped, while smaller particles pass through to the next filter stage. The washable pre-filter reduces the load on the more expensive HEPA filter, thereby making it last longer.

Maintenance of Washable Pre-Filter

The washable pre-filter needs to be removed and washed regularly to ensure its cleaning and reusability. The cleaning frequency depends on the level of air pollution in the environment. The pre-filter should be rinsed under running water and let to dry before reinstallation. Over-cleaning of the pre-filter can cause damage to its structure.
