Dehumidification can be complicated. So if you have a question, we’re pretty sure to have an answer. Because as the old saying goes, there’s no such thing as a dumb question.

How do dehumidifiers work?

A dehumidifier’s job is to correct and maintain the proper level of humidity in an area. When the relative humidity goes above your set point, the dehumidification starts. Its fan will collect the humid air from the surrounding pulling it into the unit’s cooled coils. Condensation will then occur extracting the excess moisture from the air. The collected moisture will remain in the coils to be dripped down to the unit’s tank. The remaining air will then be reheated to the right level of temperature before being exhausted back to the room. The air output is now considered at a safe level of humidity.

What is the function of a dehumidifier?

A dehumidifier extracts all the excess humidity from the indoor air. If your home always hot and muggy, this caused by the excess humidity. A dehumidifier ensures the humidity levels in the house remain under 50%.

What is the source of moisture?

There are several sources of humidity in the house. Outdoor humidity is the major contributor to humidity in your home. This is why should ensure your home remains air-sealed. However, some rooms like the laundry room, kitchen, and the basement have relatively higher levels of humidity. Other sources include rainfall, poor drainage around the house, humidifiers and leaking pipes.

HeadingWhen should you use a dehumidifier?

If you notice any of these signs in your home, it's time to put a dehumidifier to work:

1. sticky, swampy or stuffy rooms.

2. Condensed windows.

3. Musty odors.

4. An increase in mold or mildew.

5. Water stains on walls or ceilings.

6. Increasing problems with pests.

7. Rotting or warping wood.

8. Aggravation of allergy symptoms.

What are the usual basement problems?

The presence of moisture is the main problem in the basements. Superfluous moisture in this basement may lead to the growth of molds. Such molds damage property and are the number one causes of the low quality of indoor air. Also, increased odors as a result of off-gassing by the mold spores can make the house inhabitable. Moisture and other allergens can damage assets such as furniture.

Why do I need to control moisture in my crawl space?

Excess moisture, introduced by way of unsealed, vented crawl spaces, contributes to wood rot, mold growth and increased pest activity, including infestation and colonization. Moisture in crawl spaces often migrates to the upper levels of the home through a “stack effect.”

How does wood rot occur in a home?

Wood rot in floor joists and support piers occurs when the moisture content is above the fiber saturation point, which is about 27-28% wood moisture content.

What factors should be considered when choosing the capacity of a dehumidifier?

The number one factor to consider when choosing how many pints of water removal you will need for your space is infiltration from the ground below and the air outside – experts say about 95% of the moisture entering a building enters through air infiltration. It’s also important to make sure your basement or crawl space is sealed, as this also is factored in the total size of a space.

What is relative humidity?

Relative humidity (RH) is the amount of water vapor in the air, expressed as a percentage of the maximum amount of water that the air can hold at a given temperature.

Due to temperature variations, RH can vary dramatically. In fact, it is not uncommon to find summertime RH levels ranging from 50% to 100% in the same home. Warmer air holds more water than cooler air and for every one degree change in temperature, the RH changes by about 2%.

Let’s assume you live in a house with a basement. If the main floor is 77°, the basement temperature may only be 67°. Even though there is only a 10° temperature difference, there is a 21% difference in RH. Because the basement temperature is closer to the 62° dew point, it will likely feel damp as well.

Homes built on a slab have a similar problem. Though the room temperature may be 77°, the temperature on the slab is much cooler. As the slab temperature approaches the dew point temperature, RH rises and condensation can form. When this occurs, mold, mildew, and other biological growth soon follows.

Other symptoms of high humidity include:

Musty odors

Allergic reactions to mold or dust mites

Cupped wood floors

Feeling sticky or clammy

Visible condensation or water stains

Peeling wallpaper or blistering paint

What Is an ideal home RH?

The EPA recommends an ideal relative humidity between 35% – 50%. In order to maintain this level, a specialized high capacity dehumidifier is typically required as most air conditioners and conventional dehumidifiers are not designed to consistently achieve dew points low enough to avoid condensation or high RH levels. Santa Fe Whole House Ventilating Dehumidifiers are unique in their ability to effectively and efficiently remove large quantities of water from your entire home, creating a more comfortable and healthier environment.

HeaHow does APTOOK make its housing?

APTOOK uses an injection molding method. Compared to conventional Rotomolding injection molding is much faster and produces a more precise and uniform product.

What is Rotomolding?

Rotomolding is the process of filling a hollow mold with a shot weight material. It was a slow process used in the 1940s, and it rotates the material slowly to soften and stick the material to the walls of the mold.

What is Injection Molding?

Injection molding is a unique manufacturing process for producing parts from thermoplastic and thermosetting plastic materials. Essentially, injection molding is the shaping of rubber or plastic articles by injecting heated material into a mold and allowing the material to cool to take on the shape of the mold. Injection molding is an optimal production process that allows for fast precision manufacturing.

Why does the heating and cooling system fan continue to run after the thermostat stops calling?

If the zone thermostat is set to operate the heating and cooling system fan constantly, the system fan will continue to run at the end of a heating or cooling call. The AlorAir zoned comfort control system also has the ability to expel any remaining conditioned air into the living space at the end of the call by operating the heating and cooling system fan. This process is referred to as fan purge and typically last 1–2 minutes. Often times the heating and cooling system has a fan purge option as well. If using the system fan purge the AlorAir zoned comfort control system fan purge may be turned off. Your HVAC installer will know how to do this.

How should i store my dehumidifier during winter?

Make sure that you properly drain the machine before storing it in a clean space. Remember that it should not be placed somewhere with an extremely high temperature.

What can i do if the unit is producing loud noise when running?

For this one, kindly check if the unit is placed on a firm flat ground. Next, check if the filter mesh is jammed. If it is, safely remove the mesh and clean it.

How should one ship the equipment?

You may ship the unit by FedEX Express Saver.

What to do if the dehumidifier stops working?

for all our customer we highly recommend you call or send an email to our technical team for help. Our technical team is always available 24 hours to help all our customer with any problems they encounter. Or you can check the device guide available on the site.

How long will the dehumidifier last? 

Aptook dehumidifiers are built to be durable and last for over 20 years.

What is the difference between capacity at saturation and capacity at AHAM?

 the amount of moisture a dehumidifier is able to extract at 100% relative humidity is the capacity at saturation. The capacity at AHAM refers to the amount of moisture that a dehumidifier is able to extract under normal humidity levels. Check out our page of dehumidifier capacities for more information.

What is the ideal humidity levels in the house? 

between 40 – 50% of humidity level. At this level of humidity, the house will be comfortable and cool. It is also important to note low humidity levels below 25% can cause discomfort, eye irritations, and respiratory problems.
