High efficiency particulate air (HEPA) filters are used to filter contaminate particles out of gas streams. HEPA filters are greater than 99.97% efficient at removing particles ~0.3 µm in diameter. Their efficiency is even higher at larger and smaller sizes. Examples of applications include filtering particles upstream of gas analyzers, filtering particles upstream of sensitive devices such as flowmeters and filtering the effluent of instruments so as not to contaminate ambient or cleanroom environments. Our HEPA filters come in many sizes with convenient options to connect inline your process. The CI-22-barb HEPA filter is our smallest filter and most economical. Flexible tubing can be connected to the inlet and outlet tube stub and it will also work with a compression tube fittings.
