Industrial filtration demands solutions that are both efficient and scalable. For industries ranging from botanical extraction across to food and beverage processing, the ErtelAlsop Pak® Lenticular Filter stands out as a “workhorse” depth filter module. Designed to provide superior particle retention and high flow rates, these lenticular cartridges are an essential component for critical processing lines.
At Purecowater, we understand the complexities of solid and liquid filtration. This guide explores the capabilities, specifications, and applications of ErtelAlsop Pak Lenticular Filters to help you determine if they are the right solution for your facility.
What is an ErtelAlsop Pak Lenticular Filter?
The ErtelAlsop Pak® is a depth filter cartridge, often referred to as a lenticular module. Unlike standard surface filters that trap particles only on the outer layer, these depth filters utilize a tortuous path through a thick media matrix to capture contaminants throughout the entire depth of the filter.
The “lenticular” design consists of stacked filter cells (ranging from 5 to 18 cells, with 16 being common) assembled into a single unit. This configuration maximizes surface area within a compact footprint, allowing for high solids loading capacity and extended service life compared to traditional plate and frame filters.
Key Technology: The Zeta-Pak® Advantage
Many ErtelAlsop Pak modules, particularly the Zeta-Pak® series, are manufactured with “Micro-Media.” This media is composed of cellulose, high-purity diatomaceous earth (DE), and a wet-strength resin. The inclusion of DE aids in forming a rigid, porous structure that sieves out particulate matter effectively.
Crucially, these filters exhibit a positive Zeta Potential. This electrokinetic charge attracts negatively charged contaminants (such as bacteria, haze, and sub-micron particles) that might otherwise pass through the mechanical pores of the filter. This dual mechanism of mechanical sieving and electrokinetic adsorption results in ultra-fine particle retention.
Did You Know? The enclosed housing design of lenticular filters eliminates edge leakage and external contamination, a significant advantage over open plate and frame filter presses.

Primary Applications
The ErtelAlsop Pak® is versatile and utilized across various high-purity industries. Its ability to remove hazes, lipids, and fine particulates makes it ideal for polishing applications.
1. Botanical Extracts
Lenticular filters are a standard in the botanical extraction industry. The diatomaceous earth media is highly effective at removing waxes, lipids, and chlorophyll from ethanol-based extracts without affecting the desired chemical profile. The high flow rate supports efficient processing of large batches.
2. Distilled Spirits & Food/Beverage
For spirits, these filters provide chill haze removal and final polishing before bottling. They ensure clarity and stability in products like whiskey, vodka, and syrups without imparting interfering odors or tastes.
3. Chemicals & Cosmetics
Used for the filtration of perfumes, lotions, and specialty chemicals where product consistency and particulate-free liquids are mandatory.
Benefits of Choosing ErtelAlsop Pak Filters
- Scalability: Available in 12″ and 16″ diameters to suit pilot labs or full-scale production facilities.
- Operator Safety: The enclosed housing reduces exposure to fluids and fumes compared to open press systems.
- Cost-Efficiency: The depth media provides high dirt-holding capacity, reducing the frequency of change-outs.
- Ease of Use: Modules are easy to load and unload, significantly reducing downtime during maintenance.
