Introduction to ErtelAlsop Pak® Lenticular Filters
For industries requiring rigorous liquid filtration standards without the operational complexity of traditional equipment, ErtelAlsop Pak® Lenticular Filters provide a superior solution. As a leading distributor for ErtelAlsop, Purecowater offers these advanced depth filter cartridges (modules) designed to seamlessly replace heavy, labor-intensive plate and frame assemblies.
The Pak® cartridge design incorporates the high-capacity solids loading of depth filtration media into a convenient, totally enclosed, and disposable modular format. Whether you are processing pharmaceuticals, botanical extracts, or industrial chemicals, these lenticular filters ensure product purity, operational safety, and minimal downtime.
Why Choose Lenticular Modules?
Traditionally, depth filtration relied on plate and frame presses, which—while effective—can be prone to leakage, exposure to the environment, and lengthy changeout times. The ErtelAlsop Pak® system solves these challenges by stacking 5 to 18 lenticular filter cells into a pre-assembled unit.
- Sealed & Sanitary: The edge of each media pair is sealed using a patented polypropylene process, creating a robust unit that prevents bypass and leakage.
- User-Friendly Design: The modular format transforms what used to be a multi-hour media changeout into a quick, single-operator task.
- Versatile Configurations: Available in 12-inch (30.5 cm) and 16-inch (40.6 cm) diameters, these cartridges fit a wide range of housings, including vertical and horizontal orientations.

Media Formulations & Product Series
One of the primary advantages of the ErtelAlsop line is the diversity of media formulations, ensuring compatibility with virtually any fluid stream. Purecowater can help you select the exact media grade for your application.
Zeta-Pak®
The Zeta-Pak® series utilizes MicroMedia® filtration sheets, which combine cellulose, diatomaceous earth (DE), or perlite with a wet-strength resin. This series is known for its positive “Zeta Potential,” enhancing the attraction and removal of negatively charged contaminants like haze, bacteria, and endotoxins. It is ideal for pharmaceutical and high-purity food and beverage applications.
Disc-Pak®
For applications where no inorganic filter aids (like DE) are permitted, the Disc-Pak® is the optimal choice. Constructed from 100% cellulose AlphaMedia®, these cartridges are perfect for dielectric oils, perfumes, and specific food products where maintaining active ingredient integrity is critical.
Bio-Pak®
Designed specifically for the strict requirements of the biotech and pharmaceutical industries, Bio-Pak® modules offer low extractables and high-efficiency filtration for biological fluids.
Key Applications
ErtelAlsop Pak® Lenticular Filters are versatile workhorses used across multiple sectors:
- Food & Beverage: Polishing filtration for spirits, wine, syrups, and botanical extracts.
- Pharmaceuticals: Clarification of vaccines, blood plasma, and active pharmaceutical ingredients (APIs).
- Chemicals: Removal of particulate from solvents, resins, and inks.
- Cosmetics: Purification of perfumes, lotions, and essential oils to ensure clarity and shelf stability.
- Energy & Utilities: Filtering dielectric oils and transformer fluids (Electric Utility Housing compatible).
