Cannabis Filtrations Systems
From high quality water to achieving a clear and pure extract, excellence in filtration is as crucial to the Cannabis Extracts Industry as it is to the Food & Beverage and Pharmaceuticals Industries.Extracts of the active ingredients from the Cannabis sativa plant are now common options for various applications in North America. Cannabis oil extracts can be further processed to make edible products or standard extracts like medical marijuana, cbd, cannabis sativa or hemp oil.
The filtration stage of producing essential cannabis oil, medical marijuana, or hemp oil is key to ensuring product safety and quality regardless of the desired result.
That’s why reliable cannabis extract producers of medical-grade marijuana and hemp oil turn to precision equipment to achieve excellence in every aspect of the liquid product, from distillation, taste and smell to the right appearance.
The right combination of proper techniques and tools is the difference between a clear, amber extract, and a muddy, undesirable product that contains plant particles, debris, and unwanted lipids.
From research and development applications in the laboratory, to full production runs, ErtelAlsop’s food grade depth filters, equipment, and filter media are staples for producers looking for a professional result.
ErtelAlsop has a variety of equipment for your cannabis filtration requirements, including a 4-stage filtration skid for all stages and filter presses for your Dewaxing and Biomass Filtration needs.
Cannabis & CBD Oil Extraction, Filtration, Distillation: The 2-Step Process
After CO2 extraction or cold ethanol extraction, the slurry is run through an initial filter stack. Most processes then pump the liquid through a filter that catches biomass, and finally another filter media grade as many times as necessary to finalize the product and remove unwanted compounds.
Step 1: Adjust CBD & Cannabis Oil Color: Chlorophyll Removal
Achieve a clear product that can be applied to various applications. The muddy, dark brown or green appearance in the raw extract comes from the presence of chlorophyll. Activated carbon filtration effectively removes and adjusts the color and taste of your product without affecting the integrity of the product.
The results above were achieved solely through activated carbon filtration, using ErtelAlsop’s Micro-Clear MC35C activated carbon filter media.
Step 2: Polish Your Extract Before Bottling
Filter media like Micro-Media M704 with 0.45 micron retention finishes your product by removing fine particles and debris that can affect purity and appearance, and prepares it for final processing or bottling.
As with all ErtelAlsop filtration equipment, you’ll find the right filter media for your specific operating conditions. ErtelAlsop offers the widest varieties of filter media and construction techniques to provide good particle retention, clear filtrate, high flow rates, and dry filter cakes, with our variety of filter media finishes and separation capabilities.

Producing pure and safe CBD-oil is the goal of every quality-conscious manufacturer of cannabis products. Raw hemp extracts contain high concentrations of cannabinoids, and will also contain contaminants and impurities for example plant particles, chlorophyll and debris as well as unwanted oils and waxes. Therefore certain contaminants should be removed:
• bitter taste and highly unstable
• will cause degradation of cannabinoids
• very sticky components
• removal leads to smoother texture and consistency
Filtration and purification steps of CBD- oil
In order to ensure product quality and safety for CBD-oil products, filtration is essential. The following chart shows a typical filtration process. Variations might be considered depending on extraction method and type of product as well as desired quality.
