To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Do. It buy! The humidity stays at 15% even though I moved it all around the house and even outside. We have a Nest thermostat so we know the indoor humidity on the first floor and it wasn’t fpcoming close. I requested a replacement and at first the replacement seemed to work but now it too is on 15% regardless if me running the humidifier all night. I thought I could trust the Honeywell name but I guess not.

Don’t buy this for a humidity gauge it doesn’t work. Keeps reading 15 RH. The battery has to be removed to reset. The. It reads 55 RH which in Maryland would be the expected level. An hour later it’s back to 15. I’m so tired of removing the batteries to reset that this piece of junk is going in the trash where it belongs.I bought it because the $$419 Honeywell dehumidifier/air conditioner didn’t come with a humidity gauge.
We live in the high desert of the US Southwest and run three humidifiers in different rooms during the winter when heating dries out the air more than usual. I already own three humidity monitors: two Acurite 613s purchased two years ago (now $9 each) and an Extec 445815 purchased three years ago (now $40).
I bought this Honeywell to serve as a check on the other two brands. The two Acurites read very close to each other--usually the same or one percent different. The Extec always reads several percent higher. I tend to trust the Acurites more because they are consistent with each other, but I wanted another opinion, so I purchased the Honeywell.
The new Honeywell monitor has been reading five or six percent lower than the Acurites and nine to eleven percent lower than the Extec, so I have to conclude that the Honeywell is extremely inaccurate, reading far too low. The fact that the Acurites are between the extremes of the other two monitors reinforces my belief that the Acurites--the least expensive of the three--are the most accurate.
Humidity reading stuck at 15%. After days of monitoring the reading never changed. A separate device was used to compare with the Honeywell never changing from 15%. I like the size and the read out - I'm hoping the replacement will actually work. Temperature read out seems to be working correctly.
I bought one of these for home and work to measure humidity in both locations and heat at work. They’ve been getting a work out. I’ve noticed the humidity reader is most important due to headaches and bloody noses, sinus pressure problems. When it has enough humidity, these issues lessen. Recently, there was a heating issue at work and I was able to track it with a consistency stating upper 50’s low 60’s. Not sure the temp gage is correct as it will state 80 degrees with room heater running but office is still chilly.
