Limitations of HEPA filter
Dharmendra Bhaskar
Safety and integrity of personal data over digital era is the biggest threat, just adding values in making it better, reliable.
Small pollutants can escape a HEPA filter Many harmful pollutants like certain allergens, bacteria, viruses and airborne chemicals are much more smaller than 0.3 micron.
Mold and bacteria can grow on HEPA filters Microorganism can collect and multiply on HEPA filters and get released back into the air. Mold spores are large enough to be caught in HEPA filters but stay alive on the filter surface.
While bacteria are large enough to be trapped, bacteria are understood to release endotoxins into the air stream when dying on the air filter surface.
Much like VOCs, viruses are also too small to be removed. Despite this fact, HEPA based products were marketed for a long time with the claim to protect from viruses.
Volatile Organic Compounds (VOCs) are airborne chemicals that mostly derive from off-gassing of building materials or products in our homes as well as cleaning products aside from other sources like beauty products.
HEPA filters are unable to remove VOC’s as they simply are far smaller in size than what can be trapped.
HEPA is good at removing larger particulate matter like pet dander, pollen and dust mites. Unfortunately, mold, VOCs, viruses, bacteria, and small particulates under 0.3 micrometers can not be removed safely from the air with an HEPA-based air purifier.
Most importantly, make sure to frequently replace the filters as living pathogens like mold stay alive and can potentially reproduce on the filter surface. With higher moisture levels and elevated temperatures, bacteria and mold growth can even populate in particulate filter media such as HEPA.
Neglecting to maintain the filter may end up introducing even more pollutants into your home – and that is certainly the opposite of what we all want.
Solution :
ACESP filters are built on advanced technology to overcome above and this technology is has been invented by Dr. Daniel Teboul and being used to make domestic, industrial air purifiers by Shuddh Electronics Pvt Ltd.

1 年Hi, do you have any research showing the effectiveness of HEPA filter usage in industrial settings to reduce coliform bacteria? Thanks :)
