With companies increasingly employing air filtration technology to remove environmental contaminant types like dust, smoke and chemicals, users are often asking when they should change their filters. To keep air cleaners working their best, you should regularly replace filters and absorption media to ensure peak performance and maximize worker respiratory protection.
Changing your prefilter or primary particulate filter
When using Extra-All air filtration equipment, you should keep in mind that these devices have both a prefilter and a primary particulate filter, which work together to effectively capture impurities in the air. After a certain period, particulates may clog and slow down your system’s ability to filter out containments. In case you notice your filtration systems are not working as well, you should first check your equipment’s prefilter. If you detect the air flow is weak, change out the prefilter before moving on to the primary filter if your device still doesn’t work at full capacity.
Types of contaminants determine frequency to switch out filters
After determining whether you should switch out your primary filter, figure out the main contaminants your filter mainly works to prevent because this will factor into which filter you need to change and how often. When your air filtration equipment mostly filters out impurities like dust and smoke, the particulate filter might be the component you should focus on. On the other hand, if your system largely eliminates chemical fumes and vapors – which is the case for fume extraction equipment – you should use the right vapor removable module.
Users with gas and fume reduction filters will have to pay attention to the time between filter changes. Equipment that extracts light vapors primarily will have to be changed every 6 to 12 months. Equipment that handles more heavy vapors should be switched out more frequently with a new filter every 1 to 4 months.
With regular filter changes, your filtration equipment will work optimally to maintain a healthy environment for you and your staff.
