What is Cryptosporidium and why is it a concern in water systems?
Cryptosporidium is a microscopic parasite that can cause gastrointestinal illness. It is highly resistant to chlorine, making filtration essential for effective removal.
How does filtration remove Cryptosporidium from water?
Filtration physically removes Cryptosporidium oocysts based on particle size. Fine filtration systems trap the organisms, preventing them from passing into treated water.
What micron rating is required to remove Cryptosporidium?
Cryptosporidium oocysts are typically 4–6 microns in size. Filtration systems with absolute ratings of 1 micron or lower are commonly used to ensure effective removal.
Is filtration enough to control Cryptosporidium?
Filtration is a critical barrier and is often used alongside UV or other disinfection methods. Together, these provide a multi-barrier approach to water safety.
Where is Cryptosporidium filtration typically used?
It is commonly used in drinking water treatment, food and beverage processing, and any application where microbiological water safety is essential.

PoreFiltration is committed to supplying filtration products that support the highest standards of water quality, public health protection, and regulatory compliance across municipal, industrial, pharmaceutical, and process water applications. We recognise the critical role filtration plays in safeguarding water supplies, maintaining treatment performance, and supporting compliance with industry regulations and water quality standards.
Our filtration solutions are utilised throughout the water treatment cycle, from raw water intake and potable water production to process water, wastewater treatment, water reuse, and high-purity applications. By supporting the removal of suspended solids, particulate contamination, turbidity, and process-generated contaminants, our products help operators maintain reliable treatment performance while protecting critical downstream assets such as membranes, UV systems, pumps, and distribution infrastructure.
PoreFiltration supplies products suitable for a wide range of regulated water applications, including systems requiring compliance with Drinking Water Inspectorate (DWI) Regulation 31 requirements, potable water treatment processes, Cryptosporidium control strategies, pharmaceutical water systems, and industrial water treatment operations. We work closely with leading filtration manufacturers to ensure that supplied products are supported by appropriate technical documentation, material certifications, and approvals where required for their intended application.
Clean-In-Place (CIP) and Sterilise-In-Place (SIP) systems are critical to maintaining hygiene, product safety, and regulatory compliance in food, beverage, dairy, and pharmaceutical processing.
CIP enables the cleaning of pipelines, vessel
s, filters, and process equipment without dismantling, using controlled cycles of detergents, temperature, and flow to remove product residues, biofilms, and contaminants.
SIP follows with high-temperature steam sterilisation to eliminate microorganisms and ensure systems are safe for production.
Effective CIP/SIP design ensures:
- Reliable microbial control
- Reduced downtime and manual intervention
- Protection of filtration systems and membranes
- Consistent product quality and audit readiness
When properly engineered, CIP and SIP are not just cleaning steps they are integral to process performance and operational efficiency.

What Is Utility Filtration? 
Utility filtration refers to filtration systems designed to clean and condition fluids used in support roles across manufacturing and processing environments rather than final product filtration. These include:
Utility fluids such as compressed air, steam, water and process gases are essential to industrial operations. Their quality directly affects product safety, equipment performance and regulatory compliance. Advanced utility filtration ensures contaminants are removed before they can compromise products or damage critical assets.
Effective utility filtration prevents contamination, improves product consistency, reduces maintenance costs, and supports regulatory compliance.
