Q: What types of filters are used in EFUs?
A: HEPA filters are commonly used in EFUs, as they are capable of removing 99.97% of particles down to 0.3 microns in size. ULPA filters, which are capable of filtering particles down to 0.12 microns, may also be used in some applications.

Q: What are the installation requirements for an EFU?
A: EFUs should be installed in a cleanroom or other controlled environment that meets specific air quality standards. The unit should be mounted securely, and the filter should be properly sealed to prevent air bypass.
