When it comes to air filters, two commonly heard terms are PolyTetraFluoroEthylene (PTFE) filters and High Efficiency Particulate Air (HEPA) filters. PTFE filters are known for their exceptional chemical resistance, durability, and high filtration efficiency for challenging air filtration conditions. On the other hand, HEPA filters are designed to capture particles as small as 0.3 microns, making them ideal for environments requiring high air quality such as medical facilities and laboratories. Both types of filters have their specific applications based on filtration efficiency, environmental conditions, and user requirements.
