When it comes to industrial filtration, consistency and longevity are paramount. The 3M™ Micro-Klean™ RT Series Filter Cartridge represents a significant advancement in depth filtration technology. Designed to overcome the limitations of traditional flexible cartridges, the Micro-Klean RT Series offers a rigid, all-polypropylene solution for demanding applications.
At Purecowater, we understand the challenges of maintaining water purity and process efficiency. As a distributor for top-tier filtration manufacturers, we recommend the Micro-Klean RT Series for operations requiring substantial contaminant holding capacity and reliable particle reduction.

Rigid Construction for Consistent Performance
One of the defining features of the Micro-Klean RT series is its rigid depth filter construction. Unlike typical meltblown or string-wound filters, which are flexible and prone to compression, the Micro-Klean RT filters are manufactured using 3M’s proprietary rigid extrusion bonded technology.
Why does rigidity matter? In flexible filters, increased differential pressure can cause the filter structure to compress. This compression collapses the pores, leading to premature blinding and a shorter service life. Furthermore, compression can result in “unloading,” where already captured particles are squeezed out of the filter and back into the process stream. The Micro-Klean RT’s rigid structure prevents this, ensuring that contaminants remain trapped even as pressure rises.
Enhanced Surface Area via Grooved Design
Efficiency in depth filtration is often limited by the surface area available to the fluid. The Micro-Klean RT Series addresses this with a unique grooved design. Because the structure is rigid and self-supporting (requiring no core), grooves can be machined directly into the upstream surface without tearing or melting the fibers.
This innovation more than doubles the effective surface area compared to non-grooved alternatives. The result is a filter that promotes fuller utilization of the depth matrix, prevents premature blinding by large particles or gels, and significantly extends the cartridge’s service life.
Key Features and Benefits
- Extended Service Life: The grooved surface and rigid depth-matrix provide high contaminant holding capacity, leading to fewer filter change-outs and reduced disposal costs.
- Consistent Efficiency: Rigid construction eliminates pore collapse and unloading at high differential pressures.
- Low Pressure Drop: Exhibits exceptionally low initial pressure drop for a given filter rating, improving flow characteristics.
- Pure Polypropylene Construction: Made without adhesives, binders, surfactants, or lubricants. This ensures broad chemical compatibility and prevents downstream contamination from the filter itself.
- Regulatory Compliance: Materials comply with FDA regulations for food and beverage contact and are suitable for potable water applications.
- Eco-Friendly Disposal: The core-less, all-polypropylene structure allows for easy disposal via incineration or shredding.
