HEPA filters, short for high-efficiency particulate air filters, started in the industry and have now made their way into every part of our lives. Whether it’s filtering industrial dust or filtering pollen, bacteria, or pet hair, they’re becoming more and more of a big deal in your life.
As someone who’s been in the filter industry for a long time, I’ve been keeping an eye on the global HEPA filter market.

At the same time, they also provide air conditioning system solutions. They have unparalleled advantages in air conditioning equipment systems, allowing them to integrate their air filters and air conditioning products closely. I need to say this is something other manufacturers don’t have. Finally, by the way, they have joined the Daikin Group in 2006.

They have over 20 brands distributed in various segments. That’s their business landscape. During the COVID-19 pandemic, I remember they launched filter materials that can kill viruses. It came from one of his brands. Purafil. Many companies use this material to produce masks or air filters to help people protect against viruses. Here I can’t help but admire the important role of high-end filtration technology in special times.

You could say that other air filter manufacturers have learned a thing or two from Freudenberg. Freudenberg is the leader in the clean room and automotive paint booth industries, no question. I also want to point out that Freudenberg makes their own filter media, which means they’re in the upstream part of the industry. This gives them a big advantage when it comes to product performance R&D and cost control. In recent years, they’ve started getting into the residential filtration industry, making air filters for air purifiers and vacuum cleaners.

I bought 3M scrubbing pads at the grocery store to clean my pots. Along the same lines, many of their filters are also made for home use and everyday life, taking out dust mites, pollen, pet hair, etc. It reminds me of that saying: use technology to change your life.
