Packing: filters are packed in cardboard box for a long-term storage in a dry environment.
- Advantages:To the most other analogue filters:
- A frame is made of thick, water-resistant cardboard. Operates even at relative humidity 100%. Suitable for humid European climate.
- Firmly glued throughout all frame area. Filter construction in airtight and there no leakages of dust and other particles through connections.
- Tested according to the new EN ISO 16890 standard. Previous EN 779 expired on 01/07/2018. By not providing data according to the new standard filter supplier misleads the customer.
- Filters are manufactured from high-quality synthetic filtering media. Such filtering material is much stronger and damage resistant. The holes will not appear on the filter, which may let through the dust and other dangerous particles.
- High filtering efficiency: ePM1 70% (F7) class filter. Even the main original F7 filters have filtering efficiency of 1µm dangerous particles up to 60%. The most analogue filters are manufactured from cheap material, which filters less than 50% of these particles and therefore correspond to the lower ePM2.5 class.
To the filters with metal frame:
- Ecological factor. Cardboard is made from renewable sources that are easily recyclable.
- Filters are manufactured from high-quality synthetic filtering media. The most of metal framed filters had a media from fiberglass. A fiberglass material can be easily damaged by accidentally touching it.
- Bigger filtering area: lower pressure drops and longer service time. In our filters filtering material is 46 mm height, while in metal framed filters it is usually about 30 mm.
- Airtight construction. The filter in the metal frame is usually placed without glueing. Therefore, air leakages of dusty air occur nearby frame and media connection area.
