Top Five Questions about HEPA Filters for Cleanrooms

The use of proper air filtration equipment is essential for setting up proper cleanrooms. Manufacturers make HEPA filters for cleanrooms that meet the most stringent user regulations, making them suitable for medical or aerospace applications. Adequate filtration of airborne particles is even more important during the COVID -19 pandemic, and this article goes over the top questions we are asked about cleanroom HEPA filters for cleanrooms and COVID filtration.

What is a HEPA filter used for?

High-efficiency particulate air filtration may seem like a complicated concept, but HEPA filters for cleanrooms are those that use a combination of three different methods to collect and remove dust and other contaminants from the air. According to a U.S. Department of Energy standard, HEPA filters must remove most of the particles as small as 0.3 microns from the air, which in plain English means that only 3 out of 10,000 particles are allowed to pass through.

How long does a HEPA filter last? 

The MAC 10 original HEPA filters usually have a maximum service life of one year, which is recommended even with regular maintenance and continuous operation. It is important to note that the duration of quality maintenance also depends on the activity in the modular cleanroom. For this reason, it is advisable to check the filters regularly and also replace them when they become discolored (the factory color is white) or emit a strong odor.

Does HEPA filter coronavirus? 

Addenbrooke’s Hospital in Cambridge (UK) recently ran a study to understand the role HEPA filters for cleanrooms may play in purifying air from COVID-19 infected particles. According to their research, when HEPA filtering was combined with UV light, the system successfully and significantly reduced the affected particles. This technology can be integrated with modular cleanrooms to make your work environment safer during the pandemic. Our Hospi-guard Isoclean filters have the option to include UV-C Light and are configured for COVID filtration. 

Is there a difference between an air purifier and a HEPA filter? 

  While air filtration systems (such as the MAC 10 original HEPA filters) primarily prevent particles from passing through the air, air purification systems clean the air that passes through them with UV light rays or ozone sprays. The devices are often used in combination to achieve the highest level of cleanliness like the Hospi-guard IsoClean UV models we carry.  

Can you clean or reuse HEPA filters for cleanrooms? 

It is possible to clean and reuse permanent or washable HEPA filters for cleanrooms multiple times if it is done properly without damaging it but keep in mind not all HEPA filters are reusable. Permanent HEPA filters can usually be cleaned with a vacuum cleaner, while washable HEPA filters can be cleaned by rinsing them in cold water. However, even with regular cleaning, the product should not be used for longer than the recommended period. To ensure high efficiency, replacement is necessary after expiry. MAC 10 is an original modular, self-powered, HEPA filter ceiling grid module from Envirco. With constant improvements and innovations, it has led the way since its debut. The MAC 10 is known for being the quietest modular ceiling unit available, due to its innovative, patented design and quality construction.
