What Is an Inline Filter?

An inline filter is a filtration device installed directly within a fluid or gas line. It operates by capturing contaminants as the medium flows through it. Unlike other filtration methods, inline filters are compact, easy to install, and ideal for point-of-use filtration.

Benefits of Using Inline Filters

Enhanced System Efficiency

Inline filters enhance the overall efficiency of systems by preventing clogs, reducing contamination, and minimizing downtime. Clean flow improves product quality and extends the life of downstream equipment.

 

Compact and Versatile Design

Their minimal footprint allows installation in tight spaces, making them suitable for various configurations including under-sink systems, refrigerators, coffee makers, and even laboratory setups.

 

Easy Maintenance

With quick-connect options and simple media replacement, inline filters are cost-effective and easy to maintain.

Customers can easily add inline filters to their shopping basket or requisition list, emphasizing the user-friendly nature of the product.

Types of Inline Filters

PP Sediment Filters

Made from 100% virgin polypropylene, these filters remove particles such as rust, dirt, and sand. Ideal for pre-filtration, PP filters protect downstream systems.

 

Granular Activated Carbon (GAC) Filters

GAC filters, especially those using 100% pure coconut shell carbon, are highly effective at removing chlorine, taste, and odor. Our premium models offer a GAC iodine rating of 1,000 for superior chlorine removal.
