Cupboards may be susceptible to high levels of humidity. As a result, mould and mildew may start growing on your clothes, books or other items. In most cases, owners do not realize this until it is too late. Lingering odours are often the first indication of inadequate ventilation.

Humidity is measured using the relative humidity (RH), which should not exceed certain levels to maintain a healthy environment (typically a maximum of 50 to 65% RH). Relative humidity in dwellings should be 30 to 50% for human comfort. Higher humidity is also preferred by most insects, including clothes moths, fleas and cockroaches. The relative humidity of the air in a closet may be at a level conducive to mould growth, even when the humidity in the house is low, if the temperature in the closet is cooler than in the house. Depending on the size of the cupboard in question, there are several factors that come into play when looking for a strategy to control the humidity, including ventilation, positioning and the use of dehumidifiers. It is very important to prevent condensation on the clothing and other goods, since this can cause water damage and promote bacterial growth.

In order to control the humidity and condensation levels within your cupboards you must keep the relative humidity in check. There are several ways to accomplish this:

  • Leave closet doors open during very cold weather. If you prefer not to do so then you should at least consider the possibility of opening your cupboards up for a few minutes every day. This will ensure that enough air circulates within the space and reduces the risk of condensation.
  • You could consider the possibility of using fans to circulate air inside a cupboard.
  • Placing cupboards in a strategic location will make it more likely that it gets enough air circulation. Closets on exterior walls will be higher in humidity than the rest of the house during the heating season. You should leave a space between the wall and the cupboard it this is the case.
  • Clean out your cupboards occasionally to expose your clothing to sunlight and fresh air.

While the ideas above might help, it is important to state that they do not always address the underlying problem. If this is the case then you should acquire some dehumidifiers for cupboards. There are a variety of options at your disposal.

Consider the following when choosing dehumidifiers for cupboards.

  • Cupboard dehumidifiers come in different capacities and it is important to select one that meets your needs. The most important consideration is the size of the cupboard. Dehumidifiers are designed for a particular capacity, which determines the size of the space in which it can be effective.
  • Different dehumidifiers for cupboards use different technologies and it is advisable to do some proper research before making your final choice. For instance, there are refrigeration-type, electronic, and desiccant dehumidifiers. For a small cupboard a small desiccant dehumidifier should be sufficient. We provide a petite cupboard dehumidifier that uses silica gel and is fully rechargeable.
  • Certain cupboard dehumidifiers will produce higher noise levels, while others function silently. Refrigerant-type dehumidifiers include compressors which create noise. It is important to consider whether you want a completely silent model or not.

There several benefits associated with using dehumidifiers for cupboards.

  • Dehumidifiers remove moisture from the air which extends the life of your clothes and other valuables.
  • Mould and dust mites cannot propagate in dry air. If you dehumidify, you can breathe in fresh, clean air without musky odours, which has great health benefits.
  • Materials such as wood and metal can be damaged by excessive moisture. Dehumidification will preserve the structural integrity of your materials.
