Work great. Get about 3 days when on the lowest setting and 8 to 10 hours when on the highest setting. Easily get 24 hours on the middle setting. Has improved the humidity levels in the house. Sleeping better and feeling better with the increased humidity. Easy to refill. Able to leave them running when out of the house because you can regulate the amount of vapor being dipensed. Also can regulate the humidity level by chaning the settings from low to high as necessary. Very quiet with no impact on sleep from the slight hum which is heard when there is no other noise.

Love that it lasts more than one day.

I purchased this two pack about a month ago; I own the same model purchased about three months ago (also from Sam's Club in-store sold in a single carton for the same price per piece). Outstanding performance, NO messy wicks to deal with, the water capacity is HUGE. Does not always last 70 hours as stated on the carton if your room is really dry. I highly suggest using filtered or bottled water. Tap water will leaving the inside edges crusty with calcium or a little pinkish moldy . I experimented with the first machine. No issues since using filtered or bottled water now.

We bought 3 of these to put around our house. They are virtually silent which is great compared to what we had before. On low I can go 3 days between fills but have the ability to put on medium or high if I want more humidity. It is very easy to fill

You have to clean everyday or the water starts smelling moldy.

I always have a humidifier running as I get frequent nosebleeds, especially in the cold, Canadian winters. I've used other humidifiers that require a filter and I found the filters too expensive and annoying to keep up with. I also had a large, tower humidifier that somehow leaked, and I experience none of these issues with the pureguardian humidifier. I love the nightlight feature as well. On the lowest setting, I find the humidifier lasts 2-3 days. On the medium setting, it lasts 1 day. I have not used it on the highest setting yet.

This humidifier is a lot bigger than it shows which was a bonus! I needed one with a good enough mist to really help the environment in my room. We use furnace heat during winter and we live in dry climate so I was in need. This humidifier is perfect. It has almost no sound except a trickle as water gets into the tube to be vaporized but it’s so calming and nice. If you like hearing trickle fountains for peace this is it. I’ll be buying a few more for the rest of the house as I am very satisfied.

Bought it for my mom few weeks ago for her home and she likes it. She’s saying that it slightly helps her as she’s coughing less frequently. I have a central humidifier in the hose, but never use it. In the basement and lower level the percentage of humidity is always around 45-50. Only in upper levels it will occasionally go down to 35-40. As I work from home, I decided to get one for my office which is on the upper level, room size about 35m2. I’ve been running it every day for the last week or so. I did notice that the unit will increase the moisture in the room for about 3-5%. I have it running from 7 am to midnight or later. 70 hours on one tank – not a chance! On the level 2 I have to refill the tank in the morning and later in the evening, although not full at this time. It doesn’t matter to me, as it is very easy to do. Overall, I think that for the price I couldn't get better humidifier. It does the job where I need it. Did I mentioned that it is extremely quiet? It would work in the bedroom without any noise issue.

[Employee of walmartcanada] Perfect unit! Small and compact and works like a charm!! With its small size you'd say there is no way this unit (on low) is going to go without filling for 70 hours!! I filled it one Monday morning and it went till almost Friday morning! (On low). 3 easy settings and a cute glow lite for evening or child's room! Easily covers our open concept living room/kitchen of 25 by 25 foot room with ease! On high, I had so much condensation on my windows I had to cut back! Love this unit! Easy to fill, clean and use!

This is a great little humidifier, it sits on my end table in the living room and covers the entire room and my dining room as well. Once filled it lasts for more than 2 days not quite the 70 hours as stated but overall I am extremely satisfied. Would definitely recommend to anyone looking for a room humidifier.
