Also bought some for our extended family before the winter season starts. We have all noticed the difference in their breathing and sleep.
Its handy to monitor humidity near air purifier.
Very good and useful instrument. I live in a house with exposed beams & no insulation. Very surprised at the humidity readings at ground level,up roof height are very big differences so great for keeping eye on what can potentially be a dust mite or moisture issue in room. Ours is freezing in winter & stinking hot in summer. Really takes humidity off the room.
Love it use every nite ,wouldn’t be without it
After reading about air purifiers machine I decided to give it a goal. My 6yo son has bad asthma and used to snore like an adult. This year his asthma hit him very bad, making him use steroids many times. I received the machine on a day he was struggling. Put the machine on and stayed up monitoring him. After half an hour he stopped coughing completely and he bRely snore now. I couldn't believe! Very happy with results. I highly recommend this machine.
