What Constitutes Healthy Air?

  • Healthy air is free from bacteria, germs, and viruses
  • Healthy air is free from dust, allergens, and other airborne particles
  • Healthy air is free from smoke and unpleasant odors
  • Healthy air contains negative ions
  • Healthy air has a comfortable and healthy humidity level

How Does the Dreval Air Purifier Work?

  1. The air in the room first passes through and becomes absorbed by the Cold Catalyst Filter. Harmful gases (such as ammonia, formaldehyde, toluene, TVOC, benzene, xylene, and hydrogen sulfide) are eliminated.
  2. Next, the air passes through the Cellular Activated Carbon Filter, which has a 98% absorption rate, and also absorbs odors and harmful gases.
  3. The Antimicrobial Filter is next and with a particle retention rating of 5 microns and a 99% bacteria removal rate, it kills dangerous bacteria and other microorganisms.
  4. The air then travels through the HEPA filter where 99.97% of particles 0.3um and larger, such as smoke, dust, bacteria, viruses, allergens, and other pollutants, are removed.
  5. Before re-entering the room, the air is first cleaned and bacteria is removed with the UV Germicidal Lamp.
  6. The optional Negative Ion Generator can be switched on to enrich the cleaned air with negative ions.
  7. The Humidifier function helps maintain suitable and appropriate humidity levels in the room by emitting healthy mist into the air to improve air quality.
  8. Finally, the Intelligent Odor Sensor System determines and then indicates the quality of the air in the room with the color RED for Poor, ORANGE for Normal, and GREEN for Excellent Air Quality.

7 Stages of Air Filtration and Purification

  • Cold Catalyst Filter: Breaks down harmful gases, kills copious types of bacteria, decomposes and removes toxins, and helps eliminate toxins such as ammonia, benzene, hydrogen sulfide, formaldehyde, xylene, TVOC, toluene, and myriads more.
  • Cellular Activated Carbon Filter: This filter has a 98% absorption rate, removes odors from the air, and absorbs harmful gases.  Its plethora of small, low-volume pores increase the surface area for a more thorough and effective absorption and removal process.
  • Antimicrobial Filter: With a particle retention rate of 5 microns and an additional antimicrobial rate of 99%, this filter works as an antimicrobial agent and eliminates dangerous microorganisms and bacteria from the air.
  • HEPA (High Efficiency) Filter: Meeting the HEPA (High-Efficiency Particulate Absorption) Standard and satisfying standards of efficiency set by the US Department of Energy, this filter removes 99.97% of particles sized 0.3 um or larger.  It also removes smoke, dust, bacteria, viruses, allergens, and much more, and is regularly used in facilities and locations such as medical offices and facilities, aircrafts, homes, automobiles, airports, offices, department stores, and countless others.
  • UV (Ultraviolet) Sterilization Lamp: This 245nm wavelength ultraviolet germicidal lamp kills bacteria, eliminates musty and other foul odors, and helps prevent the spreading of viruses and bacteria through the air.
  • Intelligent Odor Sensor System: This remarkably advanced air purifier actually tells you the quality of your air!  With its Intelligent Odor Sensor System, the purifier determines the breathing quality of the air at any particular time and indicates the quality with a 3-Color System – Red for Poor, Orange for Normal, and Green for Excellent Air Quality.
  • Humidifier: Helps maintain suitable, appropriate, comfortable, and healthy humidity levels in the room.  This function also emits healthy mists into the air to improve air quality.
