due to a road diversion, my residential road has become a main road with irritating amount of traffic. My baby Was struggling with constant allergies ( running nose, blocked nose, always breathing thru mouth) and i was also constantly having phlegm, dry-red eyes etc. I got this item as it seems to be certifed from the allergy and asthma association. I can tell that it is quite effective in immediately reducing the intensity of allergies. within 2-3 days of using, my baby started breathing easily and my problems also disappeared. interestingly, my quality of sleep has also improved. not having fine particulates in our lungs are far more beneficial than we think. make sure u close your windows and doors of your room when using this. i use it with the AC in the room or the fan in the room and the whole room feels so comfortable.Ease of use - childishly simple, my kid operates it herself as there is only one button.Noise - super quiet when used in night mode. i first run it in the room at max mode for 15-20 mins, then change to night mode when going to sleep.weight - very light, u can carry to any room u want. seems to be just ~1 kg weight.So i am a happy customer. long term review will depend on life of filter and easy availability of replacement filters. wud happily recommend to anyone who struggles with dust allergies or who lives in areas prone to traffic.
