So you want to find the best quiet dehumidifier for your house or basement? In most situations, the basement dehumidifier goes to work down in the basement where it does not bother anybody. But when you need to run a quiet dehumidifier in a bedroom, or in a living room, then it becomes an issue! Typically, when you have a busy household with music and people talking, chances are you will pay no attention to a quiet dehumidifier in the corner of the room. But when the house falls silent at night time, suddenly the background noises become more noticeable.
The most obvious solution for a quiet dehumidifier is simply to turn the machine off at night time when people are trying to sleep. However, if you need a dehumidifier to work at its peak, it is designed to run for 24 hours to maintain the correct level of humidity in the air. When the dehumidifier is not running, then you suffer from the alternative problem of high humidity and discomfort. The only way to maintain control of the relative humidity levels is to run the best quiet dehumidifier all day and night.
Can the best quiet dehumidifier reduce noise to zero?
Unfortunately, when it comes to running a quiet dehumidifier, there is always an element of fan noise and blowing air that cannot be eliminated. The best quiet dehumidifier should have a variable fan speed selection. A slower fan speed should result in lower noise output, which may be satisfactory for sleeping. The fan can be stepped up during the day when it does not annoy anyone.
Use a smaller and quiet dehumidifier
Another solution to the problem is to select a smaller unit which produces less noise. Rather than relying on a single large dehumidifier to manage the humidity levels, you could select several smaller to distribute in different rooms around the house. With this technique, you can use a smaller and more quiet dehumidifier in the bedroom which does not keep you awake at night. But with the use of several separate dehumidifiers, you can achieve the required level of moisture extraction from the air.
Or you could go for a whole house dehumidifier
Another approach is to go for a much larger unit, such as a whole house dehumidifier. One of these units is normally situated outside or in the basement, where the noise is not a problem. These units operate be drawing air through a ducted air conditioning system, so if you already have a ducted system then this can be a good solution for a quiet dehumidifier! A whole house dehumidifier is much more powerful and efficient than a small dehumidifier. If you need to remove a large amount of moisture from your house, then this may well be the best way to go about it.
The first tip here when comparing sound levels is to make sure you are comparing like with like. If the advertised noise level of a quiet dehumidifier is referring to low fan setting, then be aware that it will be noisier when you turn the fan higher. Don’t get sucked in the advertising because you may find that your old dehumidifier is no better or worse than a new quiet dehumidifier. Sound levels can be tricky because of the way sound is measured in decibels. The sound measurement scale is logarithmic. This means that 80 is much more than twice as loud as 40. In actual fact, 43 decibels is twice as loud as 40! For every 3 extra decibels (dB), the sound level doubles. A normal conversation between two people standing side by side is normally rated at around 60 dB. This means that every 3 dB above 60 means that you will have trouble hearing that conversation. The scale of decibels increases so rapidly that a level of around 80 db is enough to affect your hearing, and anything above that will require hearing protection! Anything above 60 dB is not a quiet dehumidifier!
Is there such a thing as a silent dehumidifier – Fact or Fiction?
Technically there is such a thing as a silent dehumidifier, known a s a desiccant dehumidifier. But for this type of quiet dehumidifier to work efficiently, they have been designed with fans to circulate the air over and around the desiccant. So instead of a silent dehumidifier, even the desiccant variety may not be totally silent. Make sure you check out the details before you make a decision! The typical Desiccant dehumidifier is generally a very small unit with limited capacity. The desiccant is a chemical product which can be difficult to dispose of, and they can also be expensive.
Is a Peltier Process a quiet dehumidifier?
When you really need a nice quiet dehumidifier, the so called Peltier dehumidifier refers to design that requires minimal moving parts. This type of quiet dehumidifier uses an innovation design to remove excess moisture from the air, but still involves a fan, so there is always some unavoidable noise. The Peltier models are a great choice for quiet dehumidifier, but they are limited in terms of larger capacity. So if you need a mid range quiet dehumidifier, then this may be what you are looking for.
The next issue to be considered is the level of humidity. If you only need to reduce the relative levels of humidity then a quiet dehumidifier is possible. If you need to remove significant levels of moisture from the air in a building, then a heavy duty is required, and a small quiet dehumidifier just won’t cut it.
