Industrial filtration requires precision, scalability, and reliability. For operations demanding high-efficiency depth filtration with high solids loading capacity, ErtelAlsop Pak® Lenticular Filters stand out as a premier solution. As a trusted distributor for major industrial filtration brands, Purecowater provides access to these advanced lenticular modules to help you tackle complex solid and liquid filtration challenges.
What Are ErtelAlsop Pak® Lenticular Filters?
ErtelAlsop Pak® depth filter cartridges (also known as lenticular modules) are designed to provide the superior retention capabilities of depth filter sheets in a convenient, enclosed cartridge format. Structurally, the module resembles a stack of double convex lenses (hence “lenticular”).
Each module is constructed from varying numbers of stacked filter cells (typically 5 to 18). These cells utilize ErtelAlsop’s premium depth filter media—such as MicroMedia®, AlphaMedia®, or MicroClear®—sealed by a patented process. This design packs a massive surface area into a compact footprint, allowing for high flow rates and exceptional particle retention.
Why Choose Lenticular Depth Filtration?
Unlike surface filters that only trap particles on the top layer, depth filters trap particulate throughout the entire cross-section of the media. This complex matrix of fibers provides:
- High Solids Loading: Capable of handling fluids with a heavy particle burden without blinding immediately.
- Zeta Potential: Many ErtelAlsop media options carry a positive electrokinetic charge (Zeta Potential) to attract and hold negatively charged sub-micron particles, including haze and bacteria.
- Zero Leakage: The edge-sealing technology and robust core compression ensure that bypass is eliminated.

Available Media Configurations
ErtelAlsop offers distinct media formulations to optimize the filter for your specific liquid stream. Purecowater can help you select the exact media grade required for your process.
| Media Series | Composition | Best Application |
|---|---|---|
| Zeta-Pak® | Cellulose & Filter Aid (DE/Perlite) | The “Workhorse.” General pharmaceutical, biotech, and food/beverage filtration. High zeta potential. |
| AlphaMedia® | 100% Cellulose | Applications requiring no mineral extractables or silica content. |
| MicroClear® | Activated Carbon Impregnated | Color, odor, and flavor correction. Removes organics without handling loose carbon powder. |
| AquaKv-Pak® | Specialized Formulation | Removal of water and moisture from dielectric fluids and transformer oils. |
Primary Industrial Applications
Due to their versatility and enclosed hygienic design, Pak® Lenticular Filters are utilized across a wide spectrum of industries.
1. Life Sciences & Pharmaceuticals
Used for the clarification of cell cultures, removal of protein hazes, and pre-filtration prior to final membrane sterilization. The Zeta-Pak offers superior protection for expensive downstream membranes.
2. Food and Beverage
Essential for the polishing of distilled spirits, wines, and syrups. They effectively remove hazes and suspend particulate without altering the desirable flavor profile of the product.
3. Botanical Extracts
In cannabis and hemp processing, these filters (often seen in “Cannaskid” systems) are critical for winterization—removing waxes, lipids, and chlorophyll from ethanol extracts.
4. Chemical & Industrial
From silicone production to specialty chemical clarification, the polypropylene construction ensures compatibility with a comprehensive range of solvents and process fluids.
