Filtration –
How does it work?
The most simple filter form is that of a sieve or mesh. This means: Bags retain coarse impurities such as hair, sand grains and fuzzy stuff. Even the most simple paper bag does that for more than 30 years. Modern filter bags do much more. Besides coarse particles they also retain minute dust particles. And that is more important than ever. Because the smallest germs pose the greatest dangers. The discussion in recent years about particulate matter or fine dust has caused public awareness on this subject: A particle size of less than one thousandth part of a millimeter increasingly impact sensible people such as allergic persons. Many customers demand that the air exhausted by a vacuum cleaner contains less particles than regular ambient air. This means: A modern hoover with a fully synthetic filter bag all but cleans ambient air.

Modern dust filter bags have to be all-rounders.
The BRANOfilter teams of specialist have intensively researched a wide range of filter media. Due to the correct combination of different filter layers, a dust filter bag can retain an enormous number of particles without impeding air flow. Another advantage: Even an almost full bag retains its high performance.
Filtering. Flowing. Bonding.
Hoovering is perfect teamwork.
The better the various filter systems interact, the better the resulting ambient air. Step one: Large dust particles are retained by a sieve. What follows is the actual task of a filter. The air is cleaned in a pre-filter and passes through a filtration layer. This layer is made of “Meltblown” – a web of extremely fine synthetic fiber with a thickness of less than one thousandth part of a millimeter. The result: A very high number of these small particles are bonded to this web. Cleanliness down to the smallest detail. |
