Advanced Depth Filtration for Industrial & Sanitary Applications
For industries requiring high-purity filtration with superior solids loading capacity, ErtelAlsop Pak® Lenticular Filters stand out as a premier solution. As a key offering in Purecowater’s filtration portfolio, these depth filter modules provide a scalable, leak-free, and highly efficient method for clarifying liquids across pharmaceutical, chemical, and food & beverage sectors.
What are ErtelAlsop Pak® Lenticular Filters?
The ErtelAlsop Pak® serves as a modular depth filtration system. Unlike surface filters that trap particles only on the top layer, these lenticular cartridges utilize a thick, porous matrix to trap contaminants throughout the entire depth of the media. This design significantly increases the dirt-holding capacity and lifespan of the filter.
The “lenticular” design consists of stacked filter cells (ranging from 5 to 18 cells per unit), assembled into a 12-inch or 16-inch diameter cartridge. The edges of these cells are sealed using a patented process (typically polypropylene), creating a coherent unit that resembles a stack of double convex lenses.
Key Features & Performance
ErtelAlsop cartridges are often pre-impregnated with filter aids like Diatomaceous Earth (DE) or activated carbon. This structure forms a rigid, porous cake that not only sieves out particulate matter mechanically but also utilizes electrokinetic adsorption (zeta potential) to capture ultra-fine particles and haze that might physically pass through the pore structure.
- High Solids Loading: The complex fiber matrix allows for substantial retention of waxes, lipids, and fine particulates.
- Zero Leakage: Sealed edges and double O-ring or flat gasket configurations ensure no fluid bypass.
- Scalability: Available in industry-standard 12″ and 16″ diameters to fit various housing sizes.
- Media Variety: Formulations include MicroMedia®, AlphaMedia®, and MicroClear® to target specific contaminants.

Common Applications
Due to their versatility and material purity, these lenticular filters are the “workhorse” for many critical processes.
Botanical Extraction & Hemp Processing
In the extraction industry, removing waxes, lipids, and chlorophyll without stripping desirable compounds is critical. The Pak® lenticular filters provide the high flow rates and lipid retention needed for ethanol-based extraction workflows.
Food & Beverage / Distilled Spirits
From haze removal in craft spirits to the polishing of syrups and flavorings, these filters ensure clarity and shelf stability without affecting odor or taste.
Chemical & Pharmaceutical
Used for catalyst recovery, decolorization (using carbon-impregnated modules), and bulk chemical filtration where handling loose filter powder is hazardous or inefficient.
