Dehumidifier for Basement Buying Guide

The first step to take in the fight against potential fungus is to measure and assess the level of humidity in the basement. This parameter will help you easily determine why moisture gets into your room so often and will basically allow selecting a powerful dehumidifier.

Please note that you will also need to buy a special device to measure humidity level – hygrometer. With this device, you will be able to measure the exact level of humidity in the room, which will help you purchase a suitable dehumidifier.

What causes dampness in the basement

  • Lack of ventilation: Basements often lack a ventilation system; ventilation may be installed incorrectly or may be faulty which results in its inability to ensure a constant flow of fresh air into premises. This will cause condensation on the basement ceiling and walls.
  • Subsoil water: If your basement is located nearby subsoil waters, increased humidity is most likely caused by them, since any water flow can easily get into such premises. This tough challenge can be easily solved by high-quality waterproofing.
  • Inadequate house weather-proofing: If homeowners weather-proofed the house wrong and ignored some factors during the process, then moisture will sleep into the house every time it rains.
  • Poor or missing drainage system: There must be a quality drainage system around the house as, without it, the moisture will get into the basement in rainy weather. If the drainage system is installed incorrectly and cannot fully remove water during rain, the water will accumulate in the basement or even flow there. As a result, you will have to pump the water yourself.

Why do you need a dehumidifier for your basement?

Most basement owners often face the problem of dampness caused by high humidity. Perhaps, you have experienced a situation when you have a weird and funny feeling of discomfort when going down to the basement.

Excess moisture in the air accumulates as condensation on the walls and ceiling. What is more, increased humidity levels contribute to other problems, such as mold and mildew. Once you get rid of dampness that all basements are prone to, you will also forget about such widespread problems as rust, mold, and allergens. Damp basement ruins your home interior decoration and harms your health; therefore, you must know what to do with it while you still can.

To control excess moisture and condensation, we recommend using a dehumidifier. The dehumidifier can reduce the humidity level and pull accumulated moisture out of your walls. Once you install this device in your home, you’ll know how to dry your basement efficiently and without extra cost.

Basement dehumidifier types

Two types of dehumidifiers can be used in basements:

  • compressor dehumidifier;
  • desiccant dehumidifier.

Compressor dehumidifiers first cool down the air stream, causing excess moisture to precipitate in the form of dew and collect in a special tank. Then, the air is heated to the initial temperature. Desiccant dehumidifiers make the airflow pass through the tank with an adsorbent that pulls and retains moisture.

Your choice will depend on when you need to dry your basement: desiccant dehumidifiers work well at low temperatures, and compressor devices are best suited for high temperatures. Many claim that compressor dehumidifiers can operate at a temperature of 39 to 41 degrees Fahrenheit, though according to customer reviews, they start malfunctioning even at ten degrees (when cooling, the water freezes and you need to defrost it).

How do basement dehumidifiers work?

Any basement dehumidifier collects condensate in a special tank. If you missed the alert or simply forgot to empty the tank, the device will automatically turn off and produce a sound alarm. Its safety system will prevent the liquid from overflowing and creating potentially dangerous situations.

If you’re going somewhere, you’d better take advantage of the autonomous operation feature. There is a special drainage pipe built into the device body, which can be used to drain moisture into the sewer. Now, you don’t even need to pour out the condensate – the pump will do it for you.

The dehumidifier is a complex modern appliance but you will not feel it in any way. The device is low-maintenance and does not require frequent check-ups or repairs. You just need to clean filters at regular intervals and follow simple maintenance advice.

What to look for when choosing a dehumidifier for your basement?

# Performance

The main dehumidifier characteristic is moisture removal. This parameter shows how many liters of moisture your device can remove from the air per day.

It is important to select the dehumidifier that will be able to dry all the excess moisture released in the room.  Remember that in most cases, manufacturers indicate the dehumidifier performance by measuring the moisture intake at a temperature of 86 degrees Fahrenheit and humidity of 80%, while most residential premises where this equipment is required have the air temperature of 71 F – 75 F with the humidity maintained at 60%. With these parameters, the humidifier is less productive – on average by 20-25%.  Keep it in mind when making your choice.

# Operating temperature mode

When choosing the dehumidifier, consider its operating temperature ranges.

If your basement is not heated, forecast the temperature inside it during a cold winter. Do not listen to anyone telling you that compressor dehumidifiers retain their dehumidification efficiency at temperatures above 41 degrees. In fact, compressor models are effective at temperatures above 59 F. The higher the temperature, the higher the ability to remove moisture. At temperatures below 50 degrees, this dehumidifier spends most time in the defrosting mode and its dehumidification capacity is almost ineffective. 

If the temperature in your basement is below 59 F, it is best to use a desiccant dehumidifier – a household version of the device will work just fine.

# Air exchange

This is the most important parameter that only a few people consider when selecting the dehumidifier.

Air exchange (sometimes air flow rate) is measured in cubic meters per hour (m3/h). This parameter shows how much air your dehumidifier will run through the compressor (while drying) within an hour. For effective dehumidification, air exchange (m3/h) must exceed the air space by 2-3 times. Otherwise, the device will not be able to run the moist air through it fast enough regardless of its moisture removal capacity.

For example, if the basement (or living room) area is 60 m3, then select the dehumidifier with an airflow rate (air exchange) of 150-200 m3/h. Then, your basement dehumidification will be effective while the humidity will be maintained at a permanently normal level.

# Condensation collection tank

If you don’t feel like going down to the basement several times a day to drain the condensate from the tank, connect a drainage tube and condensate will not be collected in the tank but will be discharged into the sewer (or wherever you direct the drainage tube).

However, sometimes there is nowhere to direct the drainage tube due to the lack of sewage in the basement. In this case, consider the dehumidifier tank volume. The larger it is, the less maintenance it needs.

# Power consumption

Please note that in a damp basement, your dehumidifier may be on most of the time and therefore consume electricity. Dehumidifiers of the same capacity and power can consume absolutely different electricity volumes. This depends on the dehumidifier manufacturer and brand.
