Why buy a dehumidifier?
In a perfect world we would all live in sunny houses, with large spaces, natural ventilation, incredible views…. (yes, I already stopped the alarm clock 😉 ). The reality is that many times we find spaces or houses where for different reasons -such as insufficient ventilation or the construction system-, there are problems of excess of humidity in some rooms, which cause mold or other problems to appear, such as paint chips or a bad smell. And in these cases the best dehumidifier is the ultimate weapon ;-).
Sometimes this problem is only detected if the space has been unused for a long time, as sometimes happens with second homes. The area where we live is also an important factor, since in areas with high environmental humidity -such as near lakes or the sea-, it is always easier for the humidity in our spaces to be higher than desirable.
The first thing to assess is what our situation is. A certain amount of humidity in the environment is necessary; if an excessively humid environment is harmful, so is one that is excessively dry (in this case a humidifier -which does just the opposite-, could be used). Normally, the correct amount of water in the air is considered between 50% and 60%, being between 40% and 70% considered acceptable. Outside these parameters, unwanted effects can already occur, both for health (dry mouth, headaches …) and for the environment (mold, odors, …).
Remember that a dehumidifier basically removes water from the air, so if this is the effect we want, we always have to ask ourselves if we have any solution that avoids the problem, such as whether we can improve ventilation in the room or space. It is better to look for solutions to avoid the problem than using others to minimize its impact. This is the case of some heating systems such as butane stoves, which are large generators of environmental humidity, while others, such as heat pumps, dry it out.
What should I take into account when choosing a dehumidifier?
The first thing is always to assess the magnitude of the problem and see how to attack it. At this point we already assume that the actions of ventilation, changes of heating system or waterproofing of the space have already been carried out, so we are already going to minimize or eliminate the problem with a dehumidifier.
At this point we have to take into account some important aspects when choosing:
- Space measurements: it is an aspect that will decide on which equipment to choose according to the need for coverage in square meters that we have to attack.
- Environmental temperature: it will be a factor to take into account, both related to the temperature from which we start and to the one we want, since there are technologies that tend to heat the environment and others to cool it.
- Humidity level: if we are near or far from the desired one.
- Portable or not: will we always have it in the same place or do we want to be able to use it in different rooms?
- Loudness level: is it a noisy space so operation will not be noticed or is it a very quiet space?
- Level of care: does the water that we extract from the environment go to a tank or drain? If the space we want to control is in regular or sporadic use, it may need different approaches.
- Electricity consumption: even though it is low consumption equipment, it is constant, so it must be taken into account, especially in installations such as those powered by solar energy.
- Filter system: each machine has a filtering system and maintenance. Its correct use, for example washing the filters if they allow it, will be important for a healthier operation.
- Programming capacity: having continuous or intense modes of use, or periodic programming will condition the equipment to choose.
- Technology it uses: basically, there are usually three types:
- Those that use drying consumables such as dry gel. They do not need power but their performance is quite poor and consumables must be replaced regularly. Here you can see some examples, but we will not analyze them because they are very limited solutions.
- Refrigerant dehumidifiers: like an air conditioner with a compressor. They tend to cool the environment and work in a more optimal way the more temperature difference exists between that of the room and that of the appliance. They normallywork better, that is, with less consumption and more performance, at medium-high temperatures.
- The drying dehumidifiers: They work with some absorbent material, such as silica gel. They tend to heat the space, and although they operate in a higher temperature range than the previous ones, their performance is generally lower. They also have a slightly higher power consumption and a lower noise level.
Once we have seen its general aspects, let’s get on with it.
Which is the best?
Frigidaire High 70
Both this equipment and its brother, the Frigidaire 50, are a safe bet in terms of performance. If you are looking for pure and lasting efficacy, you are in front of the right machine. Its ability to dry 70 pints of water per day allows it to perform in spaces up to 4500 sq.ft..
Sober in appearance, more focussed on of performance than on aesthetics. It is not lavish on many programs, leaving you to choose only the desired degree of humidity and two fan speeds, but it really does not need much more.
As the only points against it perhaps the weight if we have to move it often, although it has wheels; besides, so much power can be seen in the electricity bill if we constantly use it.
hOmeLabs 22 1,500
A very balanced humidifier, ideal for most situations. Good quality and an aesthetically accomplished finish that fit it in almost all spaces.
Its performance is good, 30 pint / day, for a fairly contained size and indicated for spaces up to 1500 sq.ft. Within the same range are its top siblings, the hOmeLabs 35 (50 pint / day and up to 3,000 sq.ft.) and the hOmeLabs 50 (70 pint / day and up to 4,500 sq.ft.).
Its programming is absolutely minimalist, focused on ease: three programs (comfort, continuous and turbo), desired humidity and a clock.
Pro Breeze 500
A real best seller at a devastating price. Its weight and size content make it ideal for small spaces, where performance is not the priority.
Its compressorless peltier technology (the same as in those camping refrigerators that cool about 10 degrees ambient temperature) is not a prodigy of performance, but its electricity consumption is ridiculous, so you may always have it on without problems. To give an example, it is good for a small room and always have it on, but it would be too short for a larger space or to help drying clothes. It is also true that this type of technology makes it quite quiet.
Although its contained size is one of its strengths, it is also one of its limitations: its deposit of only half a liter makes it necessary to think about emptying it more frequently than in other models.
Its main asset is its appearance. We are in front of a humidifier that faces their competitors in terms of performance, but that justifies a slight price increase in exchange for a more careful aesthetic, and this may be important in some cases.
It also has two brothers with a range of superior characteristics, the 35 and the 50, with greater capacity, but in our opinion this one is perhaps the most balanced, being able to work in rooms up to 1500 sq.ft.
Simple programming, in line with all its competitors. The washable filter system is well resolved and we especially liked that the water level can be seen easily.
SEAVON 2020 Mini Dehumidifier
Another mini dehumidifier to compete in the small category. Intended for confined spaces, up to 170 sq.ft. in this case, but very useful in some uses.
It competes directly with the previously analyzed Probrezze 500, and at the level of specifications they are almost the same, even with a very similar aesthetic.
The choice between one and the other will be due more to tastes and to which we find in a better offer than to other criteria, since within their limitations -but taking into account their orientation to small spaces and mobility-, both will do a good job.
