Tips for Choosing Cleanroom Filters

Written by ATSC230@545404 on . Posted in Content Management

The cleanliness of cleanrooms (like those that exist in the medical or semiconductor industry) is a constant concern for those who are responsible for maintaining the sanitary conditions that are mandatory for performing work in these rooms. Strong bacterial-fighting cleaning supplies can keep walls, floors, equipment, surfaces and other areas clean. Personnel can follow rigid hygiene regimens and wear frequently-laundered protective clothing along with head and mouth coverings, but the real hero of achieving contamination control is the air filtration system. The air filtration system relies heavily on filters that trap harmful contaminants. Experts who sell cleanroom filters & supplies, like Atlantic Technical Systems, know the importance of air filtration filters and would like to tell you about some of the different types of filters which may work best for your particular filtration system.


Standards published by the American Society of Heating, Refrigeration, and Air Conditioning Engineers include three criteria: dust spot efficiency, arrestance, and dust holding capacity. There are two main types of filters, HEPA and ULPA. High-Efficiency Particulate Air Filters (HEPA filters) vary in quality, performance, design, frame construction, pressure resistance, sealant, and temperature capabilities. Ultra-Low Particulate Air Filters (ULPA filters) are even more efficient than HEPA filters. They are designed to eliminate 99.999% of contaminants.


  • Filter Application
The key here is individual testing. Batch testing is not a sufficient testing method for these filters. Also, the filter should be tested according to the specific application for which it will be used.
  • Filter Energy Savings
Deep-pleated HEPA filters are best for energy savings. They require less force to push the required amount of air through the filter.
  • Roomside System Filters
These filters have the advantage in that they are far easier to replace than regular ones. The changing of a filter can cause interruptions in work, risk the entry of contaminants into the atmosphere, and can take a lot of time. The changing of filters in roomside systems can eliminate all these risks and problems.
  • Custom & Odd Sizes
Filters can come in odd sizes and sometimes need to be custom made. Make sure to find cleanroom supply dealers who stock the sizes you need and who can keep these sizes in stock for you.
  • High Temperature Filters
In some high temperature applications filters will need to have specific frames and sealants that can handle the high temperatures. Keep this in mind as you shop for air filters. The sanitary condition of your cleanroom is critical, so you need to know that the air filtration system filter you have guarding the circulated air is of high quality and is the right one for your filtration system. Shop only the best cleanroom HVAC dealers you can find to keep your cleanroom germ free.
