Bag Air Filters

MANN+HUMMEL's range of bag air filters (or pocket filters as they are known in some regions) offers the ideal solution for a number of applications. Innovative frame and pocket designs mean our bag filters offer industry-leading performance and quality assurance you can rely upon. What's more, through the careful selection of different media types (from inherently antimicrobial to the latest nanofibre technology) there is a bag filter below to meet your individual clean air needs.

SoniQ II


Packed with features, SoniQ II bag air filters are ultrasonically-sealed (hence the name) to nullify the drawbacks associated with traditionally sewn pockets. Removing stitch holes is obviously the main benefit, but this method of sealing also provides greater strength, uses less space inside the pocket and also lessens the risk of contamination from within the filter.

When this is coupled with a media that resists microbial growth and the build-up of mould or mildew, SoniQ II is a filter suited to a wide range of applications, from hospitals and computer suites, through to offices and public buildings.

Improved Efficiency

SoniQ II has been specifically developed to offer high levels of filtration efficiency across its service life. A key part of this is meeting the requirements of EN 779:2012 by offering dependable performance whether clean, dirty or discharged. This is achieved thanks to SoniQ II’s enhanced media that provides high mechanical efficiency in addition to its inherent electrostatic charge, so no matter what the operating environment presents, SoniQ II will keep providing assured performance and high efficiency levels.
