Pre-filter

Impurity filtration: Straight-type pre-filters can remove large-particle impurities from tap water, such as sediment, rust, and suspended solids, ensuring clean household water.

Water equipment protection: By filtering out large-particle impurities, pre-filters can reduce damage to household water equipment and extend its service life.

Water quality improvement: As the first line of defense for household water, pre-filters can enhance the quality of whole-house water, making water for activities like washing vegetables, cooking, and bathing safer.

Prolonged life of water purifier filters: By filtering out most impurities, pre-filters can reduce the burden on subsequent water purifiers, extend the service life of their filter elements, and thus lower usage costs.

In air purifiers, straight-type pre-filters capture larger airborne particles before they reach more sensitive filters like HEPA or activated carbon filters. This extends the lifespan of these more expensive filters and improves the overall effectiveness of the air purification process.

Pre-filters in Heating, Ventilation, and Air Conditioning (HVAC) systems help maintain indoor air quality by trapping dust and allergens, improving air circulation and preventing clogs in the system's components.

Straight-type pre-filters are crucial in industrial settings where the air may contain high levels of particulate matter. They protect sensitive machinery and contribute to a clean working environment.

In critical fluid systems such as public water supplies, pharmaceuticals, and manufacturing, pre-filters protect downstream filters and components from damage and premature failure caused by contaminants.
