Choosing The Right Dehumidifier Based on Room Size August 15, 2016 – Posted in: Blog, Dehumidifiers, Industrial

Dehumidifiers have become very important equipment for homes and offices. Not only does it help improve indoor air quality, but a dehumidifier also reduces moisture – a common culprit for structural damage.

What is a dehumidifier? How does a dehumidifier work?

A dehumidifier is an electric device that eliminates moisture from the air through condensation. It works like a refrigerator. It sucks moist air from a room, takes out the water vapor, and then blow it back. The water collected by the dehumidifier goes into a collection tank which should be emptied regularly.

If you’re thinking of buying a dehumidifier, one of the most important things you should consider is the room size. On this dehumidifier for room size buying guide, you will learn how to choose a dehumidifier that is most suitable for your home or office.

Effects of High Humidity

Humidity is the amount of water vapor present in the air. Humidity in the air is normal. It is always around us. And because it is invisible to the human eye, humidity is something many of us don’t pay much attention to.

Unfortunately, high humidity does have a negative consequence on our health and our homes.

Effects on Health

Excessive humidity can be harmful to the health of children and adults in a myriad of ways. First, it can cause heat exhaustion. This condition occurs when the body tries to cool down through sweating but the same does not help and the body’s temperature continues to rise. This leads to overheating, dehydration, and chemical imbalances in the body. In the worst cases, it can lead to heat stroke. High humidity in the air also increases a person’s risk of allergies.

Effects on Buildings

High humidity suggests high moisture content which is a major cause of mold buildup. Over time, mold infestation can cause rotting of various surfaces, including wood and concrete. It can also shrink joists and studs, crack plaster, dry out furniture, and separate wood paneling.

How To Choose the Right Dehumidifier For Room Size: Features To Consider

You might ask – how big of a dehumidifier do I need?

Dehumidifiers range in sizes. Selecting the right size for your room is crucial in order to ensure the equipment’s maximum performance.

Whether you are purchasing a dehumidifier for apartments, homes, or offices, there are two very important features that you need to consider: the machine’s capacity and the airflow volume.

Dehumidifier Capacity

The capacity of a dehumidifier (which is measured in ‘pints’) is based on the amount of moisture it can collect within a 24-hour period. Dehumidifiers with a large capacity can sap moisture from a room in a much shorter period of time than those with lower capacity.

Air Flow Volume

This refers to the amount of air the dehumidifier can move over a certain period of time. The air flow volume is measured in cubic feet per minute (CFM). The recommended CFM is computed based on the square footage of the room and the humidity level in the area.

Size and Portability

Big dehumidifiers are perfect for large rooms, such as offices and commercial facilities whereas small dehumidifiers are more efficient for home use. You can refer to the dehumidifier sizing chart provided by the Association of Home Appliance Manufacturers to determine the dehumidifier room size for your home or office. Check out this dehumidifier capacity calculator to make the selection process much easier.

Water damage restoration projects require the right commercial dehumidifiers. You want to remove as much moisture from the air as quickly as possible, so the rest of the restoration work can occur.

Using too small of a dehumidifier will take a long time, and it may result in inadequate drying. Using too large of a dehumidifier means you spend more money than necessary on equipment you don’t need.

As experts in water damage restoration, the team at Aer Industries is here to help you choose the right industrial dehumidifier and provide you with the knowledge and equipment to handle your water damage restorations. Consider the following factors when deciding on a dehumidifier:

  • Surface area. The first thing to consider when attacking a water damage restoration project is the size of the space to dry. We generally break the spaces down into four different categories: It’s a simple matter of measuring the square footage of the space being restored. For any surface over 1200 sq. ft., it’s necessary to use more than one dehumidifier, as space is too great to adequately treat with a single unit. We offer great deals on the purchase of multiple units with our multi-packs of dehumidifiers. In general, we suggest the following popular models for the various room sizes:
  • Room temperature. Water turns to vapor at temperatures above 90 degrees Fahrenheit, and vapor can be removed from the air with a dehumidifier. You either need to use the heat source available in the space or bring in your own heat source to raise the temperature above 90 degrees.
  • Humidity. Depending on how dry you need to make a space, you can choose between two different technologies of dehumidifiers. Traditional dehumidifiers stop pulling moisture from the air at around a 30% saturation level, while our LGR technology can bring the humidity level to below 30%. If you can live with 30%, our traditional dehumidifiers might be adequate, but consider our higher-performance LGR offerings for greater moisture removal.
  • Air movers. Dehumidifiers remove the moisture from the air, while air movers transport saturated air to the dehumidifier. A dehumidifier would struggle to dry a water damaged room with little air flow, which is why we suggest adding 4 to 5 air movers per dehumidifier to ensure adequate air circulation in your room. Doing so allows the dehumidifier to function properly.
  • AHAM versus saturation. If you’re trying to choose a dehumidifier for a water damage restoration, you should consider the type of humidity condition. There are two different situations. The first is AHAM, or average humidity conditions, referenced at 60% humidity and 80 degrees F. The second is saturation, or more extreme humidity conditions, at 90% humidity and 90 degrees F. Note these situations when measuring the humidity in your water damaged space and choosing an Aer Industries dehumidifier.
