Delivery sooner than promised. Item received without damage. Operating smoothly. In the Ozone Sterilization mode you smell the characteristic odor of the ozone so it is supposed to work; whereas in the Anion Purification mode the bad odors of the room disappeared. I recommend it. I will track your performance to choose to buy another unit for my children's room. As ever grateful to BANGGOOD:-)

Entrega antes de lo prometido. Articulo recibido sin daños. Operando sin problemas. En el modo de Esterilización con Ozono se huele el olor característico del ozono por lo que se supone funciona; mientras que en el modo de Purificación de aniones los malos olores de la habitación desaparecieron. Lo recomiendo. Llevare seguimiento de su desempeño para optar por comprar otra unidad para la habitación de mis hijos. Como siempre agradecido con BANGGOOD :-)
