Introduction to ErtelAlsop Pak® Lenticular Filters
For industrial applications requiring superior depth filtration, ErtelAlsop Pak® Lenticular Filters represent the gold standard in performance and reliability. As a leading solution for liquid clarification, these lenticular cartridges are designed to remove particulates, hazes, and impurities efficiently while maintaining high flow rates.
At Purecowater, we supply these versatile filter modules to help industries tackle complex solid and liquid filtration challenges. Whether you are filtering botanical extracts, distilled spirits, or pharmaceuticals, the Pak® design offers a closed-system solution that ensures operator safety and product integrity.
How Lenticular Filtration Works
The ErtelAlsop Pak® acts as a pre-assembled, modular stacking of filter cells. Unlike traditional plate and frame filters, the Pak® is housed inside a sealed vessel (housing), which eliminates leakage and exposure to the environment. The "lenticular" name comes from the shape of the stacked discs, which resemble double convex lenses.
Each module consists of multiple cells of depth filter media—such as the renowned Zeta-Pak®, AlphaMedia®, or Micro-Media® series—sealed together using a patented polypropylene edge molding. This design maximizes surface area within a compact footprint, allowing for high solids loading capacity and efficient retention of ultra-fine particles.
Key Benefits
- High Retention Efficiency: Capable of removing particles ranging from 0.25 to 15 microns.
- Superior Solids Loading: The depth media matrix captures contaminants throughout the thickness of the pad, not just on the surface.
- Operator Safety: The cartridge design allows for quick changes within a closed housing, minimizing exposure to fluids.
- Scalability: Available in 12-inch and 16-inch diameters with varying cell counts (5 to 16+) to fit specific flow rate requirements.

Industry Applications
Due to their versatility, ErtelAlsop Pak® filters are utilized across numerous sectors. Their ability to hold diatomaceous earth (DE) within the media matrix makes them particularly effective for applications requiring haze removal and lipid adsorption.
Botanical Extracts & Hemp
One of the most popular uses for the Zeta-Pak® series is in the filtration of botanical extracts. The media is highly effective at removing waxes, lipids, and fine particulates from ethanol-based extractions without affecting the desired profile of the liquid. The result is a polished, clear product essential for high-quality distillates.
Food & Beverage
From distilled spirits to sugar syrups, lenticular modules provide the final polish before bottling. They effectively remove yeast, bacteria, and haze-forming colloids.
Pharmaceuticals & Cosmetics
Ensuring product safety and clarity, these filters are used for particulate removal in active pharmaceutical ingredients (APIs), fragrances, and lotions.
