Bissell Air 400 Filters

The BISSELL Air400 air purifier features three advanced filters designed to tackle many different indoor air contaminants including dust, mold, allergens, smoke, bacteria, and viruses.

  • Pre-filter 

    The pre-filter captures large particles such as hair, dander, dirt, and smoke residue. Not only does the pre-filter capture large particles, but it also prevents the True HEPA filter from getting clogged allowing the HEPA filter to work at full capacity. The pre-filter is easily removable.
  • HEPA Filter  

    The True HEPA filter does the majority of the grunt work. This filter traps 99.97% of particles that are at least 0.3 microns in size. This includes dust, bacteria, viruses, mold, and pollen. The use of this HEPA filter in combination with the power of the Bissell air purifier results in effective air purification capabilities.
  • Activated Carbon Filter 

    One of the factors that sets this air purifier apart from its competition is the advanced activated carbon filter. Carbon filters are great for absorbing all types of odors, bacteria, viruses, mold, and smoke. This air purifier’s activated carbon filter is 1-inch which is thicker than the industry standard and results in even better performance in comparison to its competition.

Filter Life

The life of these filters depends on the usage of the purifier. If you are running the air purifier at all times of the day and/or placing the purifier in locations with lots of air pollution then the life of the filters it obviously be shorter.
