Where a desiccant dehumidifier can be of use
A desiccant dehumidifier is a small, portable device. While you might be familiar with a large dehumidifier that works in a room or even a whole house, this version is quite different. Regular dehumidifiers work to separate the water molecules from the air so that moisture is taken out of your room. You will need to regularly empty the drip tray or attach a hose to a drain. Desiccant dehumidifiers, on the other hand, use a drying agent to remove moisture from the room. Think of those tiny gel packets that you sometimes get with shoes. Desiccant dehumidifiers work the same, only on a larger scale.
When you have a small item that can remove moisture from the air, the possibilities are endless. Small closets that store expensive clothes, such as silks or furs, will greatly benefit from desiccant dehumidifiers. Gun safes need to have the right humidity levels for optimum performance of both the gun and the ammunition.
One further benefit of a desiccant dehumidifier is that most of them are portable. You can use them as needed, and if you are travelling, they can easily be packed into a suitcase.
Features to consider while choosing a desiccant dehumidifier
There are many important features to consider in your next purchase of a desiccant dehumidifier. We have put together what you should know in order to find a product that works best for your needs. Remember that some work better for gun safes and some are better for RVs. Find the product that meets your needs and you will be satisfied.
Capacity/water tank capacity (for electric models)
While most desiccant dehumidifiers use special gels or powders to absorb the moisture from the air, some products do have a water tank. In this case, you will want to pay close attention to the water tank capacity, as you will have to remember to drain the water routinely in order for the machine to continue to work.
The Ivation 13-Pint Small-Area Desiccant Dehumidifier is the only electric model on our list and it has a water tank capacity of 0.5 gallons. As expected from the overall size, this is not very large. Depending on the humidity of your climate, you may need to empty the water tank weekly or even daily. If this is the case, be sure to make it a part of your routine. Additionally, you may connect a draining hose to the unit, and the need to empty its water tank will be eliminated.
When it comes to runtime, the longer the better. It’s really nice to be able to set something up and not have to worry about it for a long time. With desiccant dehumidifiers, most have a runtime of one month. After this, the absorbing agents in the desiccant dehumidifier won’t be able to absorb any more moisture and will stop being effective.
It’s important to put a reminder into your calendar to change the dehumidifier or recharge it if that’s the case. Remember: if you’ve decided to invest in a desiccant dehumidifier, then you will want to continue protecting your belongings.
The runtime will absolutely depend on your climate’s humidity. If you live in a high humidity level, but don’t want the hassle of renewing your product every two weeks, then it might be a good idea to purchase a desiccant dehumidifier with a large coverage area. This way you can stretch the time between renewals which will create much less hassle.
The coverage area of a desiccant dehumidifier refers to how large a space it will work and be able to remove moisture from. Basically, the possibilities are endless. Smaller, more portable desiccant dehumidifiers, like the Hydrosorbent Dehumidifiers Desiccant Drying Unit has a coverage area of only three cubic feet. On the other hand, the DampRid FG50T HI-Capacity Moisture Absorber has a very impressive coverage area of 1,000 square feet.
When looking at coverage area, be sure to think about where you need the desiccant dehumidifier. There’s no sense paying extra for a large coverage area when you just have a small space.
If it’s rechargeable
You’ve invested in a desiccant dehumidifier to protect your belongings. Great! Then, after one month, you realize that your purchase isn’t working anymore. Do you really have to buy a whole new product? If you buy a certain type of desiccant dehumidifier, then no you don’t.
The DampRid FG50T HI-Capacity Moisture Absorber is the only product on our list that isn’t rechargeable, although it does have a decent shelf life of six months. Other products can be recharged or their water tanks can be emptied. This process might require a bit of effort on your part, so again, make sure the maintenance of your desiccant dehumidifier is scheduled into your calendar.
You will be using a desiccant dehumidifier in a small space, so make sure there’s room for the device itself! Most products on our list are smaller than five inches squared; however, the Ivation 13-Pint Small-Area Desiccant Dehumidifier is quite a bit larger. It measures 10.6 x 6.85 x 17.35 inches.
It’s recommended that you fashion a prototype of the desiccant dehumidifier you are looking at, from a small box, and try it in the space before you purchase it. Remember: measure twice and purchase once.
Beside these basic features of desiccant dehumidifiers, you might encounter some extra, bonus ones. Some products will include two items in a purchase. If you have multiple small spaces, this is a nice feature to look out for. Other features could include a display panel for ease of use, or even an indicator light. While extra features can be a real bonus, they might include a larger price tag, so be sure they are needed before paying more.
How to reactivate a desiccant dehumidifier
Desiccant dehumidifiers use a special gel to absorb the moisture in the air. But they can only hold so much before they stop working. Thankfully, you don’t have to throw your unit out and purchase a whole new one again. Instead, you can reactivate it.
When you first get your new unit, be sure to read its instructions as the reactivation process will vary slightly for each product. However, you basically need to heat the unit in order to remove the moisture. You will want to heat the unit or part of the unit in the oven at a high temperature. This could take anywhere from three to six hours.
Some desiccant dehumidifiers need to be heated in the oven. Others will have a plug-in system that heats the machine on its own. When heating anything in the oven, remove any flammable pieces, such as plastic lids or cases.
