SUNDSTROM ORGANIC GAS FILTER A1 (217) When you’re working around solvents, fumes or any sort of organic vapours, having the right respiratory protection is absolutely essential. The Sundström Organic Gas Filter A1 (217) is designed to give you solid peace of mind on the job, offering dependable filtration performance without overcomplicating things. Built tough, easy to use, and made to slot straight into your Sundström half or full face mask, it’s a reliable bit of kit for tradies, painters, cleaners, workshop operators and anyone dealing with chemicals that need proper handling. This A1-class organic vapour filter is engineered specifically for protection against gases and vapours with a boiling point above 65°C. That means it’s ideal for common solvents used across a range of industries—everything from paint thinners and adhesives through to cleaning chemicals and degreasers. Whether you’re on a big commercial job or handling routine maintenance tasks, this filter helps you breathe easy knowing you’ve got the correct protection in place. Sundström has built this filter using plastic polypropylene, keeping it lightweight and comfortable to wear over long periods. It contains no metal parts, so it won’t corrode and is suitable for a wide variety of work environments. Inside the casing, you’ll find 70 grams of high-quality activated carbon, which is the real workhorse of the filter. This carbon is what traps and holds onto harmful vapours, ensuring they don’t make their way into your respiratory system. In performance testing, this filter goes above and beyond the required standards. When tested with 1,000 ppm carbon tetrachloride at a flow rate of 30 litres per minute, the filter holds strong for 90–110 minutes, comfortably beating the minimum benchmark of 80 minutes. During this process, it absorbs approximately 20–25 grams of carbon tetrachloride, again well above the minimum requirement of 15.4 grams. These figures give you confidence that when things get tough on the job, this filter’s up to the challenge. Pressure drop—the resistance you feel when breathing—has also been kept to a minimum. At a standard rate of 30 l/min, the filter sits between 25–30 Pa, and at a higher rate of 95 l/min, it measures 120–140 Pa. Both results fall far below the maximum allowed under standards, meaning you can work comfortably without feeling restricted or fatigued from breathing through a dense filter. One of the handiest features of the Sundström system is that you can pair this A1 gas filter with an SR510 particle filter, which snaps straight onto the front. This lets you tackle dusty or fume-heavy environments with a combination filter setup, giving you broader protection without needing separate gear. Size-wise, the filter has a 106 mm maximum diameter and is 28 mm thick, weighing in at 113 grams—light enough that it won’t throw off the balance of your mask or feel chunky on your face. It fits seamlessly into all Sundström half and full face masks via the standard filter attachment, so swapping filters is quick and painless. For longevity, it’s important to store your filter properly. Sundström advises keeping it at room temperature in a clean, dry environment. As long as the seal hasn’t been broken, the filter has a 5-year shelf life, with the expiry date clearly printed. Once opened, make sure to store it in an airtight container and away from contaminants to maintain peak performance. All up, the Sundström Organic Gas Filter A1 (217) is a dependable, high-quality choice for anyone needing solid protection against organic vapours. With excellent filtration capacity, low breathing resistance and strong build quality, it’s a must-have for safe and compliant workplace respiratory protection.
