Activated carbon filters for arable spraying
20th May 2025
The importance of operator safety within enclosed tractor cabs is taking centre stage, particularly during chemical spraying operations.
For arable farmers, who regularly handle pesticides, fungicides and herbicides, the use of activated carbon filters such as those offered by Purecab has become a non-negotiable element of safe and responsible farm management.
Spraying crops with agrochemicals is a necessary practice in modern farming, but it presents a serious risk to human health.
Standard dust filters, which are often factory-fitted in tractor cabs, are designed only to block particles like soil and pollen. They do not stop harmful airborne chemicals from entering the cabin.
This is where Purecab’s activated carbon filtration technology comes into play.
Its filters are specifically engineered to capture and neutralise chemical vapours, ensuring the air inside the cab remains safe during intensive spraying tasks.
Activated carbon filters should be replaced every 400 hours, or annually, whichever comes sooner.
Purecab filters also include indicator beads which allow you to monitor the health of your filter, through a clear window.
The pink beads are bright when at optimal health and fade to dark brown when the filter needs changing.
Purecab filters are powered by Adxorb activated carbon, which has been independently tested to deliver up to 11 times greater performance than conventional OEM filters, the company says.
Notably, they are among the few filters that meet the ASABE S613-3 international safety standard, which sets a rigorous benchmark for in-cab air quality during pesticide application.
This is not just regulatory box-ticking – this is about protecting the health of those working long hours inside machinery during peak spraying seasons.
In an industry under constant pressure to reduce costs and boost sustainability, Purecab filters offer excellent long-term value.
Rather than being disposable, the filters can be reconditioned using recharge kits.
This is less expensive than regularly changing the complete unit, allowing farmers to recharge their filters on-site, minimising downtime and maintenance costs
From Fendt to Massey Ferguson, Case IH to John Deere, Purecab supports an extensive catalogue of over 1,400 tractor makes and models.

In today’s regulatory and health-conscious environment, relying solely on dust filters is not only outdated, it’s unsafe.
Activated carbon filters from Purecab provide the necessary chemical protection UK arable farmers need, ensuring every spraying session is as safe as it is effective.
