Signs That You Need To Get A Dehumidifier

Getting a portable dehumidifier takes up space in your home and sets you back a certain amount of cash. While you don’t want to be rash in getting a dehumidifier, these tell-tale signs mean that it’s long due to having one in your home.

  • Paints peeling off the wall.
  • Molds, mildews and fungi growing rampantly.
  • Stuffy air that doesn’t ventilate off naturally.
  • Aggravating allergies symptoms due to dust mites and other allergens.
  • Musky odor permeating the air.

These signs are physical indications that your home is too humid for comfort. While you can fix cracking paint, excessive humidity leads to the growth of bacteria and allergen that may take a toll on your health.

Instead of solving the issues at the superficial level, getting a dehumidifier seems like the logical thing to do.

What’s The Ideal Humidity For Allergies Sufferers

You know that the air in your home is too humid for comfort. A hygrometer will tell you just how much it goes beyond the healthy range. If you experience most of the symptoms above, it is likely that you’ll get a reading between 70% to 90% RH.

According to the EPA, the ideal humidity for indoor should falls somewhere between 30% to 50% RH. That’s the range that you should be targeting when you got a dehumidifier. The ideal humidity range for humans is the opposite of germs and allergens.

For example, dust mites grow when the humidity is above 70% RH. Lowering the humidity is a great way to reduce dust mites and other allergens in your home.

How Does A Dehumidifier Work

The dehumidifier does exactly what it’s named after. It makes the air less humid by removing air particles in the air. A dehumidifier operates on the basic laws of physics where it changes the physical state of the vapor before trapping the liquid form of water in a tank.

You can imagine a dehumidifier of being divided into a few sections. Humid air is sucked into the dehumidifier by a ventilating fan. The humid air will first pass through a series of cooling coil that contains cooled refrigerant. As the temperature drops, the vapor turns to droplets of water.

The droplets will form along with the cooling coil and eventually drip into a bucket in the dehumidifier. The moisture-free air is then passed through a series of heating coils and is heated back to room temperature. The dry air is then released back to the room or space where the dehumidifier is installed.

As the dehumidifier continues to operate, the air in your room will get dryer as the water content in the air is converted and collected by the dehumidifier. Most dehumidifiers are equipped with sensors to monitor if the bucket is full of water and requires emptying.

Common Types Of Dehumidifiers

Generally, there are two different types of dehumidifiers that are popular.

Refrigerant Dehumidifier

The first is refrigerant-based dehumidifier which is mentioned in the above section. A refrigerant dehumidifier has a similar concept to an air conditioner, where a compressor and coolant are needed to cool the air and convert water into physical form.

Desiccant Dehumidifier

The second type of dehumidifier uses desiccants or materials that absorb water from the air.  These desiccants are placed in a rotating wheel and the air is channeled through the mechanism. Water molecules are trapped within the structure of the desiccants.

Continuous usage of the desiccants requires the water to be removed from them. Therefore, a heating element is needed to separate water from desiccants. The water is often channeled to a tank, which requires to be emptied when it’s full.

Thermoelectric Dehumidifier

A thermoelectric dehumidifier works on the Peltier effect. It uses a solid-state component that is connected to a heat sink. When the power is turned on one part the Peltier element is cold while the other is hot. Air is drawn to the cold part and water is condensed and collected. The dry air then is heated up by the hotter part of the element before being released into the air.

Each type of dehumidifier is worthy in their own right, but the pros of a desiccant dehumidifier slightly edge its refrigerant counterpart. A refrigerant dehumidifier is more efficient in removing water from the air and consumes lesser energy, but desiccant dehumidifiers are lighter, quieter and work in cooler environments.

Thermoelectric or Peltier dehumidifiers are usually used in smaller, compact units as the setup is relatively simple. As the unit involved directly generating heat, it isn’t the most efficient method to use in dehumidifying large areas.

Dehumidifier Capacity: What’s The Ideal ‘Pint’ Value?

While the internal mechanism of dehumidifiers is fundamentally similar, they are offered in various capacities. The capacity of a dehumidifier is usually expressed in ‘pints’. The value of pints determines how many pints of water can the dehumidifier remove from the air within 24 hours.

A 70 pints dehumidifier, which is a common range in the market is expected to remove that amount of moisture when turned on for 24 hours. But the question is, what is the right dehumidifier capacity for your home?

There are no hard rules for deciding on dehumidifier capacity, but it helps to understand that the area of coverage and the humidity dampness are major influences. Here’s a general guideline :

  • 30 pints for 1,500 sq. ft.
  • 50 pints for 2,500 sq. ft.
  • 70 pints for 4,000 sq. ft.

For a more comprehensive table, check out this page by EnergyStar.

It’s safer to overestimate than underestimate the capacity of the dehumidifier. You wouldn’t want to end up getting one that struggles to lower the humidity to the preferred level.

Efficiency vs Wattage, It’s Not The Same Thing

Dehumidifiers are also rated by efficiency, which is expressed in L/kWh or liter of water per kilowatt-hour. Note that efficiency is not the same as wattage as the latter implies the energy consumed by the dehumidifier in an hour.

With a few exceptions, a higher wattage dehumidifier will remove more water than lower wattage units, although the efficiency may vary. Of course, the higher the efficiency of the dehumidifier, the more savings you’ll get on your energy bill.

How To Choose A Dehumidifier To Ease Dust Mite Allergies

You seriously don’t want to be hasty when choosing a portable dehumidifier. There’s so much to be considered if you want to get the best value for money. Take these points into deep consideration when making your mind on a dehumidifier.

1. Desiccant vs Refrigerant

Both desiccant and refrigerant are dominant types of dehumidifiers and you’ll need to decide which one suits your need. Desiccant works well in a cooler climate, especially when the temperature goes below 59 Fahrenheit (15 degrees Celcius). However, refrigerant dehumidifiers tend to be more energy-efficient and they are suitable in a warmer environment.

You don’t want to use a desiccant dehumidifier in a warm area as the air released is at an approximately 10 Degrees Celcius higher than the air intake.

If you’re easily irritated by noise, you’ll want to opt for desiccant dehumidifiers as they are without the compressor used by refrigerant dehumidifiers. Also, the former is lighter than the latter, and that makes desiccant dehumidifier more mobile.

2. Capacity

Rather than going by gut feeling, it helps to measure the size of your living room, bedroom, bathroom, garage or any other areas that you’ll want to place the dehumidifier. As explained, the capacity of a dehumidifier is defined by how many pints of water it can remove from the air in 24 hours.

If you notice that your home or room is extremely damp, don’t take chances and get a dehumidifier with a larger capacity.

3. Efficiency

You don’t want to rack up a hefty increase in the electricity bill after installing a dehumidifier. Some dehumidifiers carry an Energy Star rating and that’s a good sign that it’s going to be a money-saver when you turn it on.

Other dehumidifiers may not bear the Energy Star label, but that doesn’t mean they are inefficient units. You can compare the capacity of the dehumidifier against the wattage in relative to other brands.

4. Space

Humidifiers aren’t the tiniest item to place in your home. Even if they bear the most elegant design, you’ll need to spare some space for the dehumidifier. So, plan and allocate space in advance before you get a dehumidifier.

5. Additional Features

Helpful features make using a dehumidifier easier. A hose connection automatically channels the water to drain outlet and saves you the hassle of emptying the tank every now and then. The next best thing is to have an auto-shutoff feature when the tank is full.

Some dehumidifiers are equipped with a humidistat and it allows you to have more precise control on the humidity. A humidistat is something like a thermostat but it measures humidity and disables the connection when the setpoint is achieved.

Optimizing Your Dehumidifier’s Performance

Here are some tips that will further increase the efficiency of your dehumidifier.

  • Placement is important as you don’t want the wall or any items to block the ventilation inlet of the dehumidifier. Ensure that the dehumidifier has ample space for the air to move freely.
  • Make sure that you wash the filter at least once a month. A blocked filter results in a decrease in the efficiency of the dehumidifier.
  • Don’t leave any windows or doors open when dehumidifying your home. It’s pointless if moist air keeps entering your home as the dehumidifier is trying its best to dry the air.

Safety And Precautions When Using A Dehumidifier

Before you plug in the dehumidifier to a power socket, read the guidelines provided by the manufacturer. Don’t do anything that is strictly not recommended in the guide. While dehumidifiers are relatively safe appliances, you’ll want to ensure that the power is unplugged before emptying the tank or cleaning the machine.

It’s no fun having to deal with dust mites and other allergens in a humid environment. Hopefully, some of these dehumidifiers are a great fit for your home and get rid of the dampness and stuffy air.
