5 Best Humidor Solution For Keeping Your Cigars Fresh [Complete Guide]


If you enjoy smoking, it is essential to keep your cigars at constant humidity. This will help maintain the flavor and aroma of each cigar. Cigars are very delicate; when they are not supported in the proper environment, they can start to break down. This can be due to humidity, weather, or light.

For those new to the cigar industry, a humidor is a type of storage where you can store your cigars. In this case, the cigars will be kept in humidity and dampness. Now for some people who don’t know what a cigar humidor is, this article will cover all the critical aspects of humidor solutions.

In this article,

What is A Humidor Solution

For most professional cigar humidors, there is one common ingredient: propylene glycol. This is a humectant (moisture attracting) agent, which helps preserve the flavor of your cigars after they have been rolled and packaged. It is typically added as a humidifier lubricant, but it can also be found in other similar products, such as ice water solutions, dehumidifiers, and even toothpaste.

Propylene glycol for humidors is commonly used in humidor storage tanks because it keeps the humidity at just the proper levels for optimal flavor. Propylene glycol is an inexpensive chemical that has several industrial uses.

Ideal Humidity Levels in Your Humidor Solution

If you are looking for a humidifier solution, you may want to check out propylene glycol for humidor storage. This is a safe and inexpensive way to maintain your cigars at just the right humidity level. There are other types of humidor fluids on the market, but propylene glycol is a ubiquitous component of many of them. Whether you are buying humidor storage containers or any other type of humidor product, make sure that the chemical is included.

If you want to purchase your cigars from a premium store, you can be sure that they use state-of-the-art technology when storing your cigars. Most of the humidity control equipment being sold today uses advanced electronics to maintain the high temperatures needed to stop the ageing process of your cigars.

This advanced technology allows the humidor to maintain a constant temperature of around 72 degrees. This means that your cigars are always at the perfect humidity levels needed to ensure they are at their most enjoyable. Properly storing your cigars through the use of a humidor with high-temperature control is a must if you want to enjoy your cigars to their full potential.

In addition to high humidity levels, proper humidity storage also involves the prevention of dust mites. Dust mites are parasites that can live on your cigars. If you are a cigar enthusiast, you must understand how harmful and how damaging dust mites can be to your cigars. Proper humidity storage is the best way to prevent dust mites from damaging your cigars.

How to Make A DIY Cigar Humidor Solution

The hobby of collecting cigars may appear to be easy to do: place the cigars on the shelf or within your refrigerator till you’re ready to enjoy them. But cigars are hygroscopic. This means they get dry over time in dry conditions or absorb excessive moisture in high humidity. These two effects could cause a loss in the flavor and the appearance of the finest cigars. To stop the drying and humidification, many cigar enthusiasts keep their collection items in humidors to control the humidity. Although professional solutions, often known as humidor juice, are readily available, many collectors prefer to create their own.

In this section, we will discuss how to build your own humidor solution. Most cigars are not stored properly and can have some issues as time passes. When you store your cigars at proper humidity (around 55%), it will help them to age slowly and last longer.

To begin with, you need to decide whether or not you want a glass humidor or one made of wood. If you are a beginning cigar enthusiast, I would suggest going with the glass model. These types have an inner light which is what you are going to be looking for. You will also be able to control the humidity at 100%.

Things You Will Need to Make Your DIY Humidor Solution

  • Small container
  • Oasis wet foam
  • Propylene glycol
  • Distilled water
  • Scissors
  • Bowl

Pick a small container to house your humidor product. Cigar Box’s online humidor guide recommends a travel soap dish or a film tube. Be sure that there is adequate airflow inside the container. It is possible to drill or cut some holes for airflow into the storage container.

Cut the wet Oasis foam so that it can be inserted into the container without a problem. Oasis foam is sold in blocks and is frequently employed in floral arrangements to keep flowers up to the ceiling. Make sure there should is enough space for air to circulate through the container and over on the top of Oasis foam, or the humidor solution won’t adequately control humidity.

Mix Propylene Glycol and distilled water in a tiny bowl. The amount you need will differ depending on the dimensions that you have in your Oasis foam. You’ll require enough water to moisten the foam.

Dip the foam in the propylene glycol/water solution to reduce its humidity. Don’t soak the foam since this could create a dramatic rise in moisture. You should just dampen it enough that it’s moist to the surface.

The damp foam should be placed inside the container. Attach the container to your humidor, allowing it to regulate humidity.

Learning how to make a DIY humidor solution is easy. You must follow all directions strictly, or your project will not turn out the way you would like it. Remember, you want your humidor to be as clean as possible, so you do not have to purchase chemicals to clean your cigars.

How to Use A Humidor Solution

The majority of times, you’ll need to make sure to season the wood in a humidor before using it. This is done by soaking it in distillate water, and then letting it sit for a couple of days, accompanied by an ice cube of distillate water and a closed lid.

The activator solution can be used easily. Put your humidifier on a table and place an apron underneath. The activator bottle should be opened, and pour some liquid into the humidifier. It isn’t necessary to cover your humidifier in water. Create a nice, wet. Shake the excess liquid out, wipe it clean with an absorbent cloth, and then place the humidor back in its place.

This process is to be repeated if your cigars begin to turn dry or if your hygrometer shows the humidity as less than what you would like. What do you know about when it is time to replenish it? Take a look at your humidifier. If you notice that the humidity is low, you need to fill the humidifier. It’s as easy as lifting it, and then refilling it when it’s like it’s light. Also, be sure to replace your foam each 6-12 months to ensure it stays functioning.

Different Types of Cigar Humidor Solutions

Traditional Foam-Based Humidifiers

Traditional humidifiers are made of foam and utilize the super-absorbent florist’s syringe to help hold and release water. They can be filled with propylene glycol and distilled water if you’re a fan of that and wish to better limit the release of moisture.

These humidifiers have to be replenished every two weeks. Once you’ve filled it with water, you’ll notice a surge of humidity. The humidity will gradually drop off over a few weeks. This is why these kinds of humidifiers are known in the context of “passive” “one-way” humidifiers. They only release water and don’t take it in.

Crystal Gel-Based Humidifiers

Crystal gel-based humidifiers make use of tiny crystals that transform into a gel when they are wet. This means that when water is poured into the form of crystals, they convert into a gel. When they are dry, they return to their crystal form. How can you tell when it’s the right time to replenish it? Similar to how the DEA can tell when it’s time to knock at your door: If you notice an excessive amount of crystal in the area.

Bead-Based Humidifiers

They’re the “hot” kind of humidifiers available now. They make use of silica beads which absorb or release moisture according to the humidity levels within your humidor. They should be filled with distilled water and then refilled every 2 to 4 weeks. Beads, wet = clear, dry means opaque, so you need to make sure to get them so that you can discern them.

Beads aren’t able to retain water with time. However, they will absorb some oil from your cigars. The beads need to be replaced every 3 to 4 years, which means you can be able to forgive them.

Electronic Humidifiers

Electronic humidifiers are by far the most active humidifiers available. They have a built-in digital hygrometer that can take measurements of humidity periodically during the entire day. If the humidity falls below the desired level, the fans start to turn on and let the moisture out. Once the humidity is at the desired level, the fans will shut off.

Electronic humidifiers can also be found in a variety of sizes and types. The water reservoirs typically have to be filled each month and replaced every 6 to 9 months. Most electronic humidifiers feature an alert light or buzzer that activates if the water cartridge has to be filled, but it is not required.
