Cigar Oasis Humidifiers

Accurate sensor measures the humidity and when it is less than your desired set point, the fan is activated. It draws air from inside the humidor, runs it through the water cartridge, which humidifies the air and pushes it back into the humidor. When the humidity in the humidor reaches the desired set point, the fan stops. Typically the fan goes on every time you open the humidor and from loss of humidity to the outside ambient through to leaks in the seal of the humidor.
Cigar Oasis electronic humidifiers are active units that go on as soon as the humidity drops below the desired level and will shut off when it goes back up to that level. It requires minimum attention, just a refill of the cartridge occasionally. Whereas the passive devices require frequent attention, can't humidify in dry atmospheres, use chemicals and need replacement.
See our Humidifier Comparison page to choose the best Cigar Oasis for your humidor.
Yes. We set it at the factory, but you can adjust it from 40-90%. Recommended setting is at 70%, although, it should be at whatever you like best.
Only humidity, but it does read the temperature in Celsius and Fahrenheit.
No. Most of the time the fan is not running and when it runs it is ultra quiet (same type of fan as used in computers).
It draws less than 100 milliamps and does not create any heat in the humidor.
After 5 or 6 refills or about one time per year it is recommended that you get a new cartridge in order to have the advantage of the antifungal agent protection which gets depleted over time.
The best way to refill the cartridge is to submerge it in a bowl of distilled water for 4 minutes. When time's up, take it out and let it stand on the counter another minute. Then turn it over the sink and let any loose water drain out. Dry off the cartridge and put it back together. There must be no loose visible water in the holes.
The difference is the size humidor you will be humidifying. The Cigar Oasis EXCEL is made for desktop humidors up to 4 cu. ft. or approximately 400 cigars. The Cigar Oasis PLUS is made for larger capacity boxes over 4 cu. ft. and up to 10 cu. ft. Although physically the two models look the same from the outside, the PLUS has two additional air ports in the rear of the unit and an additional hole in the cartridge. They allow the PLUS unit to draw in more air and push out a large amount of moisture for larger spaces.
Excel & Plus take up about the space 8 cigars, 4 cigars for the Ultra 3.0.
The Cigar Oasis unit fit in virtually all humidors that store 50-1000 cigars and you do not need to drill a hole or make any other modification to your humidor. There is a ribbon cable, paper thin, that slips between the cover and the base of the humidor and connects to the Cigar Oasis unit. This ribbon cable avoids any drilling of holes in your humidor.

All units are factory calibrated but you can always recalibrate to your own specifications/testing by +/- 9%
Excel & Plus: Lowest point possible with 1” minimum space for airflow throughout the humidor.

Ultra: Lid mount or upright, allow for 1” minimum space for air to flow.

Magna: Base should be as low as possible with vent flaps/fan facing the back or side of the humidor to promote airflow up, allow a minimum of 1” spacing in several shelves for air to flow. Place the remote inside the humidor approximately 9”-12” above the base for best regulation of Humidity.

Cigar Oasis for Wineadors

The general principle for ideal cigar storage/aging is the 70/70 rule, 70°F and 70% RH. So long as you keep your humidor in a temperature-controlled environment there is really no benefit to a temperature-controlled humidor. In fact, trying to regulate temperature and humidity in a small space at the same time can be challenging. For this reason, we generally recommend sticking with the traditional wood, cedar-lined humidor. It is best for cigars for a number of other reasons, including: Breathability, exchange of air, full cedar interior is best for long term aging.

So, unless you’re keeping your humidor in say a vacation home or another location that isn’t temperature controlled, you’d be better off with an old-school wood humidor.
Regardless of the size of the Wineador, be it a 100 or 1000 cigar count Wineador, we always recommend The Excel 3.0.

All Cigar Oasis humidifiers are designed for the traditional and most commonly used wood humidors. These humidors both absorb and release moisture. Wineador’s, however, have an air-tight seal which can lead to a buildup and potential over-humidification.

While the Plus 3.0 may meet the Wineador’s dimension requirements/Cigar capacity, the Excel is still the best option because the Excel works with a sealed vent design as opposed to the open vented Plus. This means that the Plus can possibly over-humidify where the Excel wouldn’t.

Smart Humidor (Wi-Fi)

Smart Humidor is a subscription-based service that allows you to monitor and adjust your set point of your Cigar Oasis Humidifier(s) via app from anywhere. Smart humidor can also provide a “threshold alert”** and when there is “low water” in your cartridge/reservoir.
  • The smart humidor app is used to connect your Cigar Oasis 3.0 to your home, office, shop or other desired location Wi-Fi network.
  • Once the Oasis device is connected it transmits data once per hour to a secured server.
  • The app acts as a window, to display the hourly data readings in a vibrant graph.
  • If you feel your set point is too high/low and forgot to change it on the unit, you can change it from the app remotely.
  • The Cigar Oasis 3.0 unit, links to your phone utilizing a Wi-Fi connection for a self-generated Access Point.
  • Easy to follow prompts in our app will ask you to choose your oasis product and guide you to enabling the Wi-Fi on the unit.
  • The Cigar Oasis 3.0 unit, is connected to your phone through the wifi settings. The app is used to pass the information for your Wi-Fi Network to the Cigar Oasis
  • The Cigar Oasis device, like many smart accessories require a 2.4ghz Wi-Fi network and will not transmit on 5ghz wifi.

Please note:

  1. All Wi-Fi routers have a 2.4 GHz band(often identified with “2.4”,”2”or “24g” at the end of the name. Example: “myHomeNetwork2.4”.
  2. Newer routers are often dual-band router, with 2.4 GHz and 5 GHz bands. “Mesh Networks” have options to make both visible for purposes of connecting. Steps to enable or disable vary by equipment.

What is the difference between 5ghz & 2.4ghz Wi-Fi ?

  1. 2.4 GHz offers stability and better range for small data transmissions, such as humidity and temperature from your Cigar Oasis 3.0. (used for most Smart accessories)
  2. The 5GHz band, which is the newer of the two, has the ability to prioritize heavy network traffic maximize network performance. Examples include, Online Gaming, HD Streaming, Large file downloads, and Remote access for work from home
Unlimited Devices – $3.99 p/m or $19.99 p/y
Cigar Oasis is designed first and foremost as a humidification device. The Wi-Fi Technology though integrated, is Optional. If you choose to use it a subscription will be charged.
The data is collected once per hour and dependent on the time of its first connected transmit.

Ex: if the first data point is for the 12:00p hour, and is pushed at 12:15p then the next data point should be visible for the 1:00p hour around 1:15p.

”Pending Validation” is an expected and automated part of the wifi setup process. In many cases it will take 15-30 minutes, in some cases it can extend to 24 hours

  1. The app collects information such as account email, device Mac ID and Device Name. It creates an Identity and passes it to the server.
  2. The Cigar Oasis, after receiving correct wifi information, sends a call to the server to ask for the identity.
  3. when the app profile ID & device ID link on the server the validation its completed.(On occasion if device is eligible for update, this will complete after the update)

What if I have been in pending Validation over 24 hours ?

the app may have passed the profile, but the device its blocked by a network setting or has been provided incorrect information for the wifi network. Please review troubleshooting page for clearing credentials and how to connect. If further assistance is required complete a, support form


No. The Caliber Hygrometers cannot be preset because they do not add humidity to their surrounding environment. They measure the humidity in the environment, so the unit will read whatever the humidity is in its environment. Calibration may be required before use.
It is registering a humidity reading below 20% RH
