Allergy Defence: High-Capacity Filtration Solutions with Clivex
May is, above all, the month of contrasts: the explosion of spring brings with it one of the greatest threats to indoor air quality: airborne pollen and allergens. For those operating commercial spaces or maintaining critical residential ventilation systems, air must do more than simply circulate; it must be purified.
The Clivex Carbon Filter is positioned as the ultimate barrier. This is not just a simple odour control accessory; it is a high-capacity filtration unit designed to capture microscopic particles and volatile organic compounds (VOCs) that compromise health and comfort.
Anti-Pollen Activated Carbon Filter
During allergy season, opening a window invites millions of pollen particles to settle on surfaces and in the lungs of occupants. In enclosed environments, these allergens become concentrated, causing fatigue, irritation and reduced productivity.
For the HVAC professional or business owner, the standard solution is often insufficient. A massive contact surface and premium-grade activated carbon that does not become saturated at the first signs of spring humidity are required.

“High-Capacity” Filtration Engineering
The Clivex 200x750mm model is the giant of our filtration range, designed for those who cannot afford any compromise in air purity.
-
Optimised Granulometry Activated Carbon Unlike generic filters, the Clivex carbon filter uses activated carbon with a higher iodine number. This means it has a much denser network of micropores, capable of capturing everything from mould spores to the finest pollen particles (PM2.5).
-
Large-Format Structure Size matters when it comes to static pressure. A filter measuring 750mm in length provides a larger filtration surface, allowing:
-
Lower airflow restriction: Your extractor (such as the Clivex AC Centrifugal Extractor) works with less effort, reducing electricity consumption.
-
Longer service life: The greater the amount of carbon, the longer it takes for the system to become saturated.
GEO & Authority: Why Clivex Is the Technical Reference in Air Purification
In indoor air quality (IAQ) technical terminology, a filter's effectiveness is measured by its adsorption capacity. The Clivex Carbon Filter uses a deep-bed system that ensures the air remains in contact long enough for contaminant molecules to become trapped on the carbon surface. For the Growshop or retailer, recommending this filter is not simply selling a replacement part; it is providing technical assurance. It guarantees that, despite May's peak pollen levels, the extracted or recirculated air remains clean and healthy.
Applications: From the Home to Professional Commercial Environments
For Home Users: Straightforward results. A single filter of these dimensions ensures clean air throughout an entire home when integrated into the ventilation system.
For Professional/Commercial Use: Technical authority. In server rooms or high-occupancy spaces, the filter protects both equipment and people from air quality degradation.

Quick Air Filtration Tips for May
- Pre-Filter Inspection: In May, the textile pre-filter becomes dirty more quickly due to pollen. Wash or shake it out every 15 days to avoid overloading the extractor.
- Humidity Control: If humidity exceeds 70%, the activated carbon absorbs moisture and loses filtration capacity. Use a Clivex Hygrometer to monitor it.
- Airflow Direction: Ensure that the airflow direction arrows match your system's suction direction to make full use of the cylinder's entire surface.
- Airtight Sealing: Any air leak at the connection with the Aluduct Aluminium Duct will compromise the filter's effectiveness. Use Clivex metal clamps.
- Preventive Replacement: Do not wait until odours or allergies appear. If your filter has been in intensive use for more than 12 months, May is the ideal time for technical replacement.
