Cigar Humidification Systems
Vigilant humidification systems provide the most versatile, most accurate cigar protection available. With the same technology we use in our humidors, you can turn a chest, display cabinet, or entire room into your own state-of-the-art humidor. Simply calculate the cubic space you need and match it with the system capacity.
Features & Benefits of our Cigar Humidifiers
In 1995, we invented the concept of the integrated humidification systems. Our systems monitor and display the humidity level of a humidor's interior and automatically maintain it to a selected setting. Prior to this concept, passive or mechanical systems were used to introduce humidity into humidors - neither of which is accurate.
Vigilant cigar humidifiers take the worry and work out of keeping cigars perfectly fresh, in spaces ranging from a few cubic feet to hundreds. They can be retrofitted to almost any cabinet and are the highest quality money can buy.
- Provide superior accuracy and reliability
- Can be sized for almost any size or shape of humidor
- Backed by a 100% satisfaction guarantee

Guardian Digital Humidification Systems
Our Guardian digital humidification systems are our most accurate and automatically control the humidity in a cabinet or a small room with the push of a button. Simply choose your desired humidity level and the system does the rest. All that is needed for these low-maintenance systems is the periodic water reservoir refill and filter change.
These systems are ideal for your 10 - 150 cubic foot humidor cabinets. If you want to humidify a larger unit - or an entire cigar tasting room or lounge, please contact us for a custom quote. Alternatively, check out our larger cigar cabinets, armoires, or in-wall humidors that accommodate collections from 750 to 2,000 cigars or more!

Sentry Humidification Systems
The Sentry humidification system electronically controls the humidity in your cigar humidor cabinet, displaying the level digitally. Compared to passive systems, the Sentry system is far superior because it is more accurate and requires less maintenance. Since no remote sensor is needed and it is simple to install, converting your cabinet into an effective humidor is easy. To maintain the desired humidity, simply periodically check the level in your cabinet and adjust the analog dial accordingly.
