Here are the tips for use so that the Bull Filter 150 x 300 650 m3/h carbon filter can last  for two consecutive years  :

– install the Bull Filter 150 x 300 650 m3/h carbon filter  within the culture space, in the center and at the height  of the latter, and  connect it to the inlet  of an  air extractor, whose flow does not exceed 650 m3 per hour  ;

– be sure to retain all its effectiveness,  exclusively for the flowering or fruiting phase , and thus, so as not to expose it to excessive humidity,  imperatively below 70% humidity,  which would definitely harm its performance; 

– keep  the pre-filter  of the Bull Filter 150 x 300 650 m3/h (wadding form surrounding the charcoal filter),  always clean and placed around the filter  when in use, in order to avoid any blockage, which could be caused by environmental pollution and plant pollen;

–  clean the pre-filter  of the Bull Filter 150 x 300 650 m3/h filter, as soon as it appears tarnished, by simply taking it off and placing it in the  washing machine at 30°C (maximum)  to finish by  drying outdoors  only.
