Kerr Humidity Control Jar Kit Replacement Kit 3ct Refill

Keep Kerr Humidity Control Jars Fresh Without Replacing the Jar

Once an Integra Boost pack in a Kerr Humidity Control Jar reaches saturation, the jar itself is still perfectly good — only the pack needs replacing. This 3-count refill kit includes fresh Integra Boost 62% RH packs along with their matching holders, letting you refresh up to three Kerr Humidity Control Jars without buying new complete kits.

Each replacement pack is calibrated to the same 62% RH target as the original kit, and the included holder drops in for correct positioning above stored product, keeping the refill process a direct swap rather than a guessing game.

Key Features & Benefits

• 3-count refill — refreshes three Kerr Humidity Control Jars per kit at a lower cost than buying new complete kits.
• Calibrated to 62% RH — matches the original kit's target for long-term cured botanical storage.
• Includes matching holders — each refill pack comes with the holder needed for correct positioning inside the jar.
• Direct replacement — sized specifically for the Kerr Humidity Control Jar system for straightforward swap-in use.
• More economical than a new kit — replacing only the pack extends the useful life of jars already on hand.

Who Should Use This

Anyone already using Kerr Humidity Control Jars who wants to keep the system running without buying new complete kits is the direct fit, especially growers managing several jars at once who want replacement packs on hand.

Frequently Asked Questions

How many jars does this refill kit cover?

The 3-count kit provides replacement packs and holders for three Kerr Humidity Control Jars. Buy multiple kits if more jars need refreshing at once.

How do I know when to replace the pack in my jar?

Use an Integra Humidity Indicator Card placed inside the jar to track RH. When the card shows humidity has drifted outside the target range, swap in a fresh pack from this refill kit.

Is this compatible with all Kerr mason jars or just the Humidity Control Jar?

This kit is built specifically for the Kerr Humidity Control Jar system and includes the holder designed for that jar format. It is not a universal fit for other Kerr mason jars.

Can I use these Boost packs without the Kerr holder?

The packs work in any sealed container, and the holder is included specifically for correct positioning in the Kerr jar. If used elsewhere, place the pack above or alongside stored product in a sealed environment.
