Developed together with the German filter specialist Freudenberg, the Dual Filter™ is the key to the outstanding air purification performance of Roger Little. The unique filter is made in Germany and combines an H14 HEPA and an activated carbon filter. 

Compared to an H12 HEPA filter, the H14 HEPA filter has a greater density, enabling more particles to be filtered from the air per air change.

The H14 HEPA filter removes pollutants such as fine dust, pollen, viruses and bacteria from the air while the activated carbon filter adsorbs gases, unpleasant odours, tobacco smoke, formaldehyde, toluene, volatile organic compounds present in the air. 

The Dual Filter™ must be replaced every 8 - 12 months, depending on its exposure to air and gases. Roger Little reminds you exactly when the filter needs to be replaced.

The filter is manufactured to the same high standard and with the same attention to detail as all the Stadler Form air purification products. 

To maintain the best performance of the air purifier, it is essential to replace the filter at the right time.
