Ultrapure water (UPW), high-purity water (HPW) is water that has been purified to stringent specifications which may include microbial, particulate, and metal contaminants. The standards of water quality will vary significantly by application and industry. For healthcare applications, the USP (United States Pharmacopeia) has 8 different classifications, with the common classification for processing high purity water being Water for Injection (WFI) and Purified Water.

Microfiltration technology is not effective in removing chlorine and fluorides in water. These are typically removed through use of carbon based adsorbent technology.

Medical devices can use a wide range of filter technologies. Graver focuses specifically upon use of PLEKX® technology for the removal and/or reduction of multiple odor, gas, fume and chemical contaminants in both doctors' offices and surgical suites.

Several essential applications for filters. Tank vent or fermentation feed air filters, the choice of which depends upon the specific method being used in the fermentation process, ensure that particles and microbes do not enter the process through air sources. These filters should utilize a hydrophobic membrane such as PTFE and have claims for sterility. A second area is to ensure that all fluids in the process are microbial-free, so filtration using a 0.2 micron hydrophilic membrane filter that is rated as sterilizing grade is commonly used. This would apply to water, nutrient broths or any liquid additive essential to the process.

Generally, HEPA filters are not intended to be washed and reused.
