Product Description High efficiency HEPA Prefilter wet laid non woven glass micro fibre, mini pleated for fine dust with solvent free separators. Suitable for all IQAir HealthPro models and GC MultiGas, VOC and Dental Units. Surface area: 2.8 square metres HEPA Class: F8 Efficiency: @ 0.3 microns IQ AIR FILTER EFFICIENCY The F8 PreMax filter's efficiency does not stop at 0.3 micron sized particles. It is estimated that the filter would have absolute minimum efficiency of around 55% for particulates, irrespective of particle size. Overall, the most important thing is almost 100% percent overall particle filtration efficiency from every IQAir air purifier for particles 0.3 μm. This particle size range therefore includes most of the particulate pollutant types which are of most concern to users such as allergy and asthma sufferers (i.e., soot, pollen, dust mite allergens, smoke particles, fine dust, bacteria). The IQAir PreMax standard filter is suitable for HealthPro 250 , HealthPro 100 ‘Allergen’ and GC MultiGas, VOC and Dental Units. However the filter contains no activated carbon or permanganate to assist in the capture of molecular gas and odours. Shelf Life Under normal indoor storage conditions the particle filters (i.e., PreMax and HyperHEPAFilters) have a virtually unlimited shelf life. Under normal indoor storage conditions and if boxes remain unopened, the V5-Cell Gas & Odour Filter will also remain usable for at least 5 years. HYPERHEPA FILTERS: The reason H12/13 HyperHEPA (as used in HealthPro models) filters can claim an efficiency of 99.95% for particles down to 0.003 microns is because these have been type-tested according to European Norm EN1822 which showed that they have an MPPS-efficiency of 99.95%.
