With so many types of dehumidifiers available to buy it can often be hard to choose one. More importantly, how do you choose the best dehumidifier for your needs? In this article we will list some of the most recommended dehumidifier systems and things to consider when choosing one.
A dehumidifier will not get rid of mold. However, a dehumidifier will hinder, or at best prevent further mold growth by removing excessive amounts of moisture from the air. The mold you already have in your home still has to be removed by yourself or by a remedial expert.
The ideal indoor humidity levels for preventing mold growth can be anything from 30% to 55%; whatever is most comfortable for you. Anything above 60% humidity is considered ideal for mold growth.
The Friedrich D70BPA is the ideal refrigerant system for attics and basements. The small, yet powerful 70 pint system (also available in 50 pint), is perfect for small spaces as well as medium to large rooms. Additionally, the roller wheels helps make it quick and easy to transport around.
The system comes with a host of built in features such as 2 speed settings, the ability to precisely adjust between 30% to 90% humidity levels, a digital display which shows you the current room temperature along with current moisture levels and a whole lot more. Removing the actual condensation the machine collects couldn’t be easier as the system has a removable condensation bucket with handle. Alternatively and much more conveniently, one could hook the system up to your home or office plumbing system.
The small yet powerful Santa Fe Compact 2 Dehumidifier has been specifically designed and engineered for tiny crawl spaces and basements. The system can dehumidify a maximum area of 3000 square feet and extract around 70 pints of moisture per day.

There’s the auto defrost function which automatically defrosts the internal components should you use it in temperatures as low as 49 degrees Fahrenheit. In addition, there is the 2 stage air filtration which not only dehumidifies the air but also purifies it from allergens.

The built in filtration system also helps purify air the air it dehumidifies; although its not effective against mold spores since it doesn’t support HEPA filters. Nevertheless, the built in LCD interface gives you control over a range of features.
Some of these features include a 24- hour timer you can easily program, a humidistat, multiple fan speeds and the system automatically notifies you whenever water levels are too high (if you haven’t connected the system to your plumbing).

Below we have listed some features and advice you should consider before purchasing a dehumidifier.
Pint Capacity: Pint capacity is only important if you’re not planning on connecting your dehumidifier to indoor plumbing. But if emptying moisture manually then pint capacity should be of concern. Most medium sized dehumidifiers have a 70 pint capacity which fulls up in a day so it only needs to be emptied once daily. Smaller dehumidifiers have around 30 pint capacity which means the bucket is emptied multiple times a day. On the plus side, a small dehumidifier has a smaller bucket which means it wont be strenuous on your back. There is no right or wrong answer here. It comes down to personal preference but it’s something one should keep in mind when choosing a dehumidifier.
Connector Hose: If you don’t like the idea of regularly emptying water buckets then its vital that the system you choose supports a connector hose. Luckily, most modern systems can and many do come with at least one included. Good quality reinforced hose connectors are cheap so it shouldn’t be of any concern if the system you purchased doesn’t have one included.
Noise Levels: Dehumidifier noise levels are important especially if you intend to sleep in the same room while its running. The speed setting on the system will make a difference in the amount of decibels it puts out; the slower the fan speed the more silent it will be. Most mid-sized systems will put out 40 to 50 decibels on low fan speed from 10 feet away which should be perfectly fine for sleeping.
Coverage Area: The size of the dehumidifier will generally determine the size of the area it can dehumidify. A good small sized system is perfectly capable of handling anything between 1500 to an impressive 3000 square feet; while some mid-sized systems can cover up to 4500 square feet. Most mid-sized dehumidifiers have caster wheels which allow you to easily move it around from place to place if needed.
Features: Modern dehumidifiers have LCD display screens where you can monitor and control various features. These features include everything from monitoring the current humidity levels, setting the desired humidity levels, timer controls and lots more. A good system should also be able to notify you whenever nearing its pint capacity.
Internal Component Defrosting: A dehumidifier capable of internal component defrosting is something you might need to consider if planning on using in extreme low temperatures. It’s a fairly standard feature in many systems and what it does is automatically shut off once it detects ice formation on its components. The system will then defrost automatically and resume its operations once done.
