Advanced Depth Filtration with ErtelAlsop Pak® Cartridges
For industrial applications requiring high-efficiency liquid filtration and high solids loading capacity, the ErtelAlsop Pak® Lenticular Filter stands out as a premier solution. As a distributor and OEM partner, Purecowater provides these advanced depth filtration modules to help facilities tackle complex solid and liquid separation challenges.
The Pak® cartridge (also known as a lenticular module) revolutionizes the traditional plate and frame filter concept. It incorporates the same high-quality depth filter media sheets but repackages them into a totally enclosed, easy-to-handle cartridge format. This design offers a leak-free environment, rapid change-outs, and scalability from lab to production.
What is a Lenticular Filter?
A lenticular filter module consists of stacked filter cells. Each cell is made of two sheets of depth filter media sealed at the edges (typically with polypropylene). These cells are stacked on a central core, resembling a series of double convex lenses—hence the term “lenticular.”
This configuration maximizes surface area within a compact footprint, allowing for high flow rates and superior retention of particulates. Unlike surface filters that only trap particles on the top layer, ErtelAlsop’s depth media traps particles throughout the thickness of the pad, significantly increasing the dirt-holding capacity.
Key Features and Benefits
- Sealed System: The totally enclosed design eliminates leakage and external contamination, making it ideal for pharmaceutical, cosmetic, and food applications.
- User-Friendly Maintenance: Unlike the labor-intensive cleaning required for plate and frame presses, these cartridges allow for quick and easy change-outs, reducing downtime.
- Versatile Media Options: Available with various media types, including MicroMedia® (with perlite/DE), AlphaMedia® (100% cellulose), and MicroClear® (carbon-impregnated).
- Scalability: Over 300 precision dies ensure these modules fit virtually any filter housing, with sizes available in 12-inch and 16-inch diameters.

Media Series and Applications
Choosing the right media is critical for optimizing filtration performance. The ErtelAlsop brochures highlight several key series:
- Zeta-Pak® (MicroMedia®): The “workhorse” of the line, incorporating filter aids like diatomaceous earth (DE) or perlite for high efficiency and zeta potential. Ideal for haze removal in spirits, botanical extracts, and biopharmaceuticals.
- Disc-Pak® (AlphaMedia®): Composed of 100% cellulose, this series contains no resins, binders, or inorganic filter aids. It is perfect for applications where mineral extractables are a concern, such as dielectric oils, organic chemicals, and essential oils.
- Bio-Pak®: Pharmaceutical-grade depth filter media designed for critical bio-reduction and pre-filtration applications.
- AquaKv-Pak®: Specifically tailored for utility and power generation applications for water purification.
Industry Applications
Due to their versatility and enclosed hygienic design, Pak® Lenticular Filters are used across a wide spectrum of industries:
- Food & Beverage: Polishing filtration for distilled spirits, syrups, wines, and soft drinks.
- Botanical Extracts: Removal of waxes and lipids from extracts (winterization) using high-flow DE-impregnated media.
- Pharmaceuticals: Clarification of cell cultures, removal of carbon fines, and active pharmaceutical ingredient (API) processing.
- Chemicals & Cosmetics: Filtration of perfumes, lotions, silicones, and inks.
