How long should it last when set for maximum output? 2.4 gal/144 hrs is the lowest output I believe (not much mist per hour).

I've never run it full blast. At 50-60%, a full tank will last 4 nights at 12 hours per night.

In the winter (now), I run mine 100% and have had to refill it every 24 hours.

We generally run at ~80% output, which is a pretty significant amount of steam, and we change out every three days or so when running continuously. During the summer we run only during the night and it lasts a week or more.

Running at 70%, I get about 6 nights (8-9 hours a night). Running at 20-30%, I get more like 10-12 nights. 70% was adequate for very cold nights; running higher didn't make a difference except more condensation on the windows. Your mileage may vary!

Hi there. Because of flow restriction (severe) I only used this a couple of times and then gave it away. Since it is a spring-wound timer, anything less than 15 minutes would be iffy, and during the last couple of minutes it would begin to shut off the water even more.

I have only had this humidifier for a month. We have very hard water, so I am only using distilled water and, so far, it is very clean. If you run the unit for 12 hours a day it goes through a gallon of water pretty quickly, so there really isn't standing water building up algae..........

I've had mine about 2 1/2 years. The fan still turns on, but the little metal plate no longer vibrates, so of course no mist is produced. :( Yes, it will also produce little or no mist if it has too much or too little water in the lower portion, but sometimes it just goes kaput regardless of any trouble shooting. For $90 I would have liked it to last longer. It was great while it lasted.

cool water is not the strongest sent, So I would say 4-5. Also does not last long maybe 2-4 hours.

When you switch on the unit a blue LED and Vapor Mist turns on if there is water in it. When the water dissipates the LED turns red and the Vaporizer turns OFF but, you still have to fully turn off the RED LED by the switch. If you run it full speed the average 16 oz water bottle will run out in about 5-6 hours, I use 20 oz 3/4 speed it last most of night. It will drop water on surrounding area be prepared for the specially on high speed...It helped me break a serious nose spray ADDICTION along with taking OTC Zertec drug, I tried many before finding one that worked for me!.

It runs a good 2 to 3 hours. There will be a little water left but other than that I think it works great.

On a full tank around 7-8 hours at half the use of mist. You can adjust the amount of mist it will dispense. The main issue is the amount of oil it will use. I filled up the tank (small separate tank) with oil and in one night the oil was completely gone. Another mister I bought on Amazon uses less water and you can mix the oil with the water and use only a few drops at a time and it works well. Hope this helps.

I timed it today and it was a little over 6 hours. It could have something to do with humidity or maybe someone else put in a little more water? I don't know. I had never timed it before but I know from the beginning it was more than 4 hours.

For me it lasts all day...I leave it on. At night before I go to bed, I refill it. I don't run it at its highest fan speed....that may make a difference. I've really found this to be relatively carefree. Let me know if you need anymore info!

Cool mist. We use ours in our dental office and it lasts from open to close, about 6 hrs.

When running under interval mist mode, the diffuser can run over 8 hours (if there is still water in the water tank).

If you are using the 2 liter setting, it will last approximately 8 hours. I have not checked the time available for 3, but I believe it is somewhere around 5 hours. The 4 liter setting will give you less time. I paid more than $310.00.

Most of it is misted inside the exhaust pipe. I run mine for 12+ hours a day and every 3-4 months I need to empty the water from a very small tank on the bottom. It surprised me how small the tank is and how much time goes between needing to empty it from the drain plug. My last unit from a different manufacture also misted but not very efficiently. I had to empty a larger tank weekly.

I don't run mine all the time so I don't have good detailed information. The setting for 'warm' or 'cool' has some effect on how long the water lasts. I am very satisfied with the unit.There are also 3 settings, "low", "medium" & "high" which will also affect the length of time that the water lasts. sorry, but I have not measured my unit under all of these different conditions, so I can't say how long it will run.

It holds exactly one gallon of water. One gallon will last between 2 and 5 depending on how much mist you use. To relieve the heat of a hot day, expect 2 hours before a refill.

The minimum pressure for the system to mist is 35 psi. The higher the pressure the better the quality of the mist, though anything above 45 psi does a good job. There are 4 nozzles and each nozzle uses between .4 gallons per hour and .58 gallons per hour depending on the pressure. You may contact us at 1-800-330-0388 if any additional questions. Thanks.
