Preserve your favorite smoke moments with the most versatile Boveda ever! ONE (1) Size 320 = FIVE (5) Size 60. Use in a large, medium or small airtight humidor to precisely manage moisture with Boveda 2-way Humidity Control.

65% RH is for:
  • Wood humidors with a tight seal, acrylic humidors and plastic humidors
  • Challenging climate of year-round high humidity
  • Storing Cuban cigars, which are tightly bound and can mold at a higher RH
  • Aging and long-term (multi-year) storage for most premium cigars
  • Better burn if cigars extinguish quickly
  • Prefer a less-humidified cigar
  • Up to 5 lb of English, flakes and other non-flavored pipe tobacco
A Single Size 320 is for:
  • More condensed humidity control for a large airtight humidor (Use a Boveda 320 instead of several Size 60 packs.)
  • Long-lasting humidity control in a small airtight humidor (In a 25-count humidor, the Size 320 provides cigar protection for up to 1 year!)


Boveda is safe to touch cigars. 

First remove the clear overwrap from the Boveda, then simply place the unwrapped pack in your humidor and close the lid, it’s that easy. Boveda 65% RH automatically restores and maintains humidity in airtight desktop and cabinet humidors, tupperdors and polymer (plastic) humidors.

Don't mix RH (Relative Humidity) levels within the same humidor. And do not use Boveda in the same humidor with other humidification products because they will fight against each other and reduce the efficiency of Boveda. 

Use one (1) Size 320 Boveda for every 100 TOTAL cigars a humidor can hold. Example: For a 250-cigar capacity humidor, use three (3) Size 320 Boveda at once. For smaller humidors, use Size 60 Boveda

Each single Boveda is individually overwrapped. 

Keep the Size 320 in its outer cardboard box—it provides protection and stability. (And attaches to a Boveda Mounting Plate, which lifts your pack up and out of the way.) If this Boveda doesn’t fit in your humidor, you can remove the Size 320 from its outer cardboard box. Just make sure the blue packet doesn’t get pinched or crimped when you close the humidor’s lid.

In a humidor: 2 to 4 months (will last up to a year in a smaller 25-count humidor)
Unopened package: Up to 2 years 

To increase the lifespan of Boveda in a wood humidor, season your new humidor with Boveda for Seasoning packs. 

Do the touch test. Order replacement packs BEFORE Boveda is totally rigid to avoid a lapse in humidity protection in your humidor.
Boveda is still working if you feel: • Hardening at its corners • Soft spots among some hard areas
Boveda is expired if: • The entire pack feels rock solid all the way through. 

It's common that the actual RH of a humidor will stabilize up to 5 points lower than the Boveda RH you use because of humidor quality and ambient dryness. In an airtight environment, all Boveda are accurate to +/- 2% of the RH printed on the pack.

Food-grade salt, purified water and a food-grade thickening agent. 

Size 320: 6.75" x 5" x 0.82" 

Slip the Size 320 onto the Boveda Mounting Plate, which affixes it to the lid of a humidor.

3 Steps to Protect


Place Boveda in your humidor right on top of your cigars or use a Boveda Holder. If your Boveda is wrapped in a clear overwrap, remove the overwrap first before putting Boveda in your humidor. Boveda is FDA compliant food safe.


Boveda will begin working immediately to precisely stabilize the humidity levels in the humidor.


Know with confidence that your collection is protected. Enjoy the perfect smoke, every time.

    No problem the Needone brand humidor.

    I have two electronic humidors. One is 48 L and the other a 23 L.

    best way to season and maintain are as follows,

    85% boveda pack in new /empty humidor, monitor it until it reaches desired RH and remove, add cigars and add the desired RH maintenance pack per number of cigars in your humidor. I have had enough of these to kmow if your humidor will not hold desired RH, you got yourself a crappy humidor. Bigger is always better. I wouldn't invest so much in cigars if it weren't for Boveda.

    So far so good

    I bought two of these because my coolidor humidifier failed. These Bovedas have kept a steady 65% for a few weeks now. We will see how long they last.

    So far so good

    65 pack not lowering RH

    Boveda packs not lowering RH after being in humidor for over a week. Maintaining an RH of 73-74. Any suggestions? These are Davidoff, Prometheus and Savoy humidors. Thanks!

    Thank you for taking the time to provide us with your feedback on our product. We are always happy to help troubleshoot your humidor. Please reach out to us at

    Boveda products will never give off more RH than is printed on your Boveda. The first step is calibrating your hygrometer.
