Think more thick and efficient filtration materials: Allerair uses super-quality military graded particulate activated carbon, good adsorption performance. The ordinary air purifier is mostly using pulverized charcoal, and the adsorption performance is poor. ALLERAIR Household Type 5000 Series Filter Carbon Dosage 8.2 kg, 6000 Series Filter Carbon Dosage Relief is 16.3 kg! And other high-end purifiers are used up to 6.8 kg! This super-high quality activated carbon has extremely powerful adsorption, it can adsorb its own weight of 60% of chemical harmful gases, and adsorbed harmful substances do not volatilize under natural conditions, and does not produce secondary pollution. However, this ultra-thick overweight filter material greatly increases the resistance of air through the activated carbon filter layer, increasing the burden on the wind output of the air purifier, and also increases the manufacturing cost of activated carbon and other components. Therefore, the ordinary air purifier uses the cost of reducing the amount of activated carbon to satisfy the design requirements of the use of activated carbon in order to reduce the cost and reduce the burden of the wind output system.
