Parker's Compressed Air Microbial Test Unit (CAMTU) detection device allows food safety personnel to quickly and easily test for contamination present in compressed air supplies that come in direct contact with food product or food packaging/processing equipment. The impurities in the compressed air may contaminate the food product which can result in change of color and taste, reduced shelf life, in addition to exposure to bacteria and other micro-organisms, can result in product recalls.
In many of these applications, compressed air is in direct contact or indirect contact with food product. Whether you choose a basic or advanced model, you can breathe easy using an activated carbon filter.Compressed air is used in a broad range of applications in the food processing industry, such as mixing of ingredients, cutting, sparging, drying of product, transporting and propelling product through processing systems, and packaging of final product. They can be used alone or in conjunction with other filters to significantly reduce the amount of impurities in your home or office. Some modern activated carbon filters are also more adept at preventing a buildup of bacteria that can occur naturally over time.Īctivated carbon filters are an important addition to any air purification system. The most advanced activated carbon filters, like those found in Blueair air purifiers, are infused with other compounds like magnesium dioxide and copper oxide to remove even more hazardous pollutants from the air, such as carbon monoxide, ethylene oxide, and ozone. Typically, smaller particles yield faster adsorption rates. Another factor that influences filtering rate is the size of activated carbon particles. It will require fewer replacements and keep emitting fresh air longer.
The more activated carbon in a filter, the more contaminants it will catch and the faster it will adsorb.Īdditionally, high levels of activated carbon increase a filter’s lifetime. Some filters contain more activated carbon than others, and this can affect the capacity for impurity removal. Are all Activated Carbon Filters the Same?Īll activated carbon filters remove a significantly higher amount of air pollutants than regular carbon filters, however there are some distinctions. If used in conjunction with a HEPA filter, the activated carbon works to prevent larger particles like dust and lint from reaching it, enabling the HEPA filter to perform better and last longer. It is then inserted into the main purifying device, such as an air purifier or HEPA air filter.Ĭontaminated air enters the filtration system, passes through the active carbon, undergoes adsorption, and leaves the filter purified. Activated carbon is typically sold in thick or thin packets for air filtration. How do Activated Carbon Filters Work?Īlthough a filtration system that uses chemical reactions to decontaminate air may sound complicated, it is actually rather simple. If you are or live with a smoker, using an activated carbon filter in your home air purification system can provide unparalleled benefits to your respiratory health. Activated carbon filters can particularly benefit people who suffer allergies or aggravation from impure air, including second hand smoke. Used together, activated carbon and HEPA filters can trap 99.97% of small particles 0.3 microns and higher as well as most larger particles, especially spores. In air purification systems, activated carbon filters can be used in conjunction with HEPA filters to trap known allergens and impurities like:Ĭarbon filters also help eliminate unpleasant odors so your indoor air remains fresh.
