Reviews of Holmes HM2409-U Comfort Select Cool Mist Humidifier

Customer Ratings:

I don't get why people don't like this. We own 3! One for each bedroom. It's perfect. Note we DON'T use the automatic mode. I simply set it to low all night. You can also do high. Low isn't loud enough for the baby's room so we do high. We need LOTS of white noise so the kids can't hear anything and wake up. It's easy to fill. You do have to push the button a lot of times to get to the low setting, but it's easy. Always use with an anti-mold liquid for each filling.

We tried a filter free kind before and YUCK! FILTERS ARE THERE FOR A REASON.

With this humidifier, I can actually sleep. A day when I forget to turn it on (rare)?? I wake up with dry skin and mouth. So, it works!!!

Also, the price is right. I had an old Kaz I loved but after 6 years of nearly 24/7 use it was so dusty I feared a fire hazard. So we got this one.

This humidifier is amazing! I have it in my baby's room and it makes such a difference with his congestion. I even slept in his room because I had a bad cold and couldn't sleep due to my sore throat, it was truly amazing! I will say that I've never played with the different modes, I just put it on high or low.

I've had this unit for two years and it has performed quite well. In a very large room on a 45% humidity setting the entire room has stayed between 40-45% relative humidity. There is also a small filter-flow indicator that detects if the airflow through the filter has changed indicating the need for a new filter. With a monthly Protec drop-in to prevent bacteria and algae growth I get a full season from a filter (3-4 months).

Honest reviews on Holmes HM2409-U Comfort Select Cool Mist Humidifier

This humidifier does the job it's intended to do (humidify). It works well in a 15 X 15 room, and it's easy to fill and operate. It is a hassle however to get through all the settings to choose the one you want (have to click the button each time to cycle through) however to turn it off in the day time just hold the button and it shuts off, next press turns the humidifier on to the previous setting.

The negatives of this humidifier are as follows:

Loud

Auto-mode doesn't really work

The Holmes HM2409-U is fairly loud on either hi or lo setting... It's a constant noise so you get used to it and can sleep through it but at first you'll definitely notice it. Like other reviewers have said, the automatic sensing mode is useless. It cycles on and off for 3 seconds which gets extremely annoying and probably does nothing to humidify.

For $30 this humidifier is worth it, I just leave it on the Lo setting with my bedroom door closed and it works fine, 1 full water tank is half empty by the morning.

Hope it helps!

It's OK in manual mode, but the so-called automatic mode where it's supposed to sense the humidity and cycle on or off accordingly is a joke. First of all, it didn't even go on in auto-mode until I had it cranked up to 55% desired humidity, and the room is as dry as a bone. Then after going on, it would turn off after about two minutes, turn on for literally a second, and so on. Hardly an effective way to humidify a room. Since we desired something we could "set and forget" for the baby's room, this doesn't work accordingly, and will be returned immediately.

Also, although it is fairly simple for someone of average intelligence to figure out, there is nothing in the manual about how to fill the tank! An obvious oversight on their part, and just another indicator of the sloppy design/manufacture of this product. The only reason I can give it two stars instead of one is because the manual mode works OK.
