Those without allergies never truly understand the daily terror that some people go through due to pollen, dander, and other particles that agitate the body’s response mechanisms. Most people are blessed with no allergy symptoms, while others can have an attack at any time which could leave them with anything from a runny nose to a hospital visit. It is because of these allergens that many companies have come out with products that help relieve the symptoms by removing them at the source. Miele is one of these companies, and the miele HEPA filter is one of the most advanced particle retaining filters on the market today. Since vacuum cleaners are the first line of defense when removing dirt, dust, and other particles from your home it makes sense that they would be optimized to actually clean and purify the air that is coming out of the exhaust.

A Miele S300-S700 Series HEPA Filter

So what exactly makes the miele HEPA filter so efficient in cleansing the air of particles when compared to other vacuum cleaners on the market? There are actually a few things:

1)      Miele uses a higher grade HEPA filtration system than its competitors. These types of filters cost significantly more to manufacture, but are the most superior in filtering out the smallest particles. This is why their filtration system will capture up to 99.99% of particles up to .3 microns in size. When other filter systems are used you actually see up to 288x more particles being released.

2)      Miele uses a closed and completely sealed system in their S5 & S6 line of vacuum cleaners. This system eliminates any particles from being released out of the vacuum once they are suctioned up. Though this does not seem like a problem vacuum cleaners have, it is actually one of the main reason why most HEPA vacuum cleaners do not properly clean and purify the homeowners living space. As an experiment, we recommend inspecting at the seals of a dyson vacuum cleaner and comparing them to that of a miele. You will find that the seals on a dyson are made of a cheap polymer and release dust if not properly aligned. A miele vacuum will not release any dust into the air, as it has to go through a 12 stage filtration system before exiting.

3)      The efficiency of the HEPA filtration is also reliant on the integration with other filters within the miele vacuum system. The high quality authentic Hyclean bags utilize seven different layers of filtration, then the air travels through a motor pre-filter, and finally through the high efficiency particle arrester (HEPA) filter which catches the smallest material. This filtering system is the best on the market and no other manufacturer has even come close as of yet.


These finding are also backed up by independent laboratories that have tested the miele canisters and uprights for particle capturing efficiency. Companies such as IBR Laboratories utilized special testing techniques that proved miele’s findings, and put them at the forefront of filtering technology.
