How to choose the size of a dehumidifier



Dehumidifiers are helpful in removing excess moisture from indoor spaces, reducing water damage and damaging mold and mold growth. However, these appliances are available in a variety of sizes and capacities, so you may have difficulty figuring out which dehumidifier is the right size for your space. To choose the right dehumidifier, you need to assess how large and humid your space is. You can also save energy and get the most out of your dehumidifier by choosing a unit with a higher capacity than recommended for your space.

[ Edit ] Find out what type of dehumidifier you need

  1. Measure the dimensions of your room or home . When selecting a dehumidifier, you must consider the size of the space you are trying to dehumidify. If you do not already know how large the space is, use a tape measure to measure the floor length and width. Multiply these measurements together to find the size of the space in square meters or meters. [1]

    • For example, if you are working with a room that is off, then this is the area.
  2. Get a dehumidifier for the entire house for a space larger than. If you need to dehumidify an entire house, it may be worth investing in a whole house dehumidifier. You can get a device designed to connect to an existing central heating or air system, or choose one that can be installed by itself. Whole house dehumidifiers are designed to work in spaces as large as.

<li>  Select a desiccant dehumidifier for a cooler environment. Dehumidifiers are available in two basic types: desiccant and refrigerant. While desiccant humidifiers tend to have lower capacity ratings than refrigerant models, they work much more efficiently at lower temperatures. <sup id=[2] In general, it is best to use a desiccant dehumidifier if the temperature in your room will fall.

    • Desiccant dehumidifier uses a hydrophilic material such as silica gel to draw moisture out of the air. Many homes contain disposable cartridges. They are usually more expensive to drive, but they are preferred in cooler spaces. Dehumidifiers for dehumidifiers also have the advantage of being quieter than refrigerant models.
  3. Buy a coolant model for a warm and humid space. If your space is consistently warm and humid, a refrigerant dehumidifier may be the best option. These dehumidifiers tend to have higher capacity ratings and work more efficiently at high temperatures than desiccants. [4]

    • A refrigerant dehumidifier uses a heat exchange coil to extract moisture from the air. You can choose a portable refrigerant dehumidifier for smaller spaces, or for a whole home alternative, you can choose one that will connect to your central air system. [5]
    • If the temperature drops below the space where you run your refrigerant dehumidifier, ice may form on the evaporator coils and prevent the unit from functioning properly. [6]
    • You can also use a dehumidifying fan if you want to move the humid air outside. These are most suitable for crawl spaces, cellars and attics. [7]

[ Edit ] Choosing your dehumidifier capacity

  1. Look for signs of humidity to find out how wet your space is. While you can measure the exact humidity level of a space using a moisture meter, it is usually not necessary to make accurate measurements when selecting a dehumidifier. To get a general sense of how humid your space is, look for clear indicators of moisture, such as condensation in the windows or damp stains on the walls. For example: [8]
      Select the size of a dehumidifier Step 5 version 3.jpg
    • Your space is moderately humid if the air feels damp or humid or you notice a tasteless smell when the weather is humid.
    • A very humid space always smells soft and feels humid. You may also notice damp stains on the floor or walls.
    • If the space is wet, you may notice water beads on the walls or floors, or moisture seeping in around the room's edges. The room will feel and smell humid all the time.
    • An extremely wet space will have obviously standing water on the floor.
  2. Get a dehumidifier with the capacity for a moderately humid space. The "size" of a dehumidifier actually refers to its capacity – that is, how much water it can draw out of the air during a 24-hour period. If your space is only slightly humid, you do not need a high capacity dehumidifier. The total capacity you need depends on how large your space is. For example: [9]
      Select the size of a dehumidifier Step 6 version 3.jpg
    • For a space that is, a dehumidifier with capacity should work.
    • If your space is, get a dehumidifier.
    • For a space, get a dehumidifier.
    • For a space, get a dehumidifier.
    • For a space, get a dehumidifier.
  3. Select a dehumidifier for a very humid space. If your space is very humid (eg always tasteless and with damp stains on floors and walls), choose a higher capacity dehumidifier. You must consider the size of the space as well as the moisture level. For example, select a dehumidifier that is: [10]

    • for a space that is.
    • for a space that is.
    • for a space that is.
    • for a space that is.
    • for a space that is.
  4. Buy a dehumidifier for a wet space. For wet spaces (for example, where there is slippage or sweating on walls and floors) you need a more powerful unit. Choose your dehumidifier capacity based on the size of your space. For example, get a dehumidifier that is: [11]
      Select the size of a dehumidifier Step 8 version 3.jpg
    • for a space that is.
    • for a space that is.
    • for a space that is.
    • for a space that is.
    • for a space that is.
  5. Go for a dehumidifier for a very wet space. If your space is wet enough to have standing water, you can buy a high capacity dehumidifier based on the size of your space. For example, get a dehumidifier that is: [12]

    • for a space that is.
    • for a space that is. [19659027] for a space that is.
    • for a space that is.
    • for a space that is.
  6. Buy a dehumidifier with a higher grade than you need to save energy. While larger dehumidifiers are more expensive to buy initially, you can end up saving money and energy by choosing a machine that is a little higher capacity than necessary. A higher capacity dehumidifier does not have to work as hard to keep a space dry as what is exactly the recommended room capacity.

    • For example, even if you dehumidify only a small room – e.g. a bedroom – it may be worth investing in a dehumidifier that is rated for in a similar humid environment.
    • You can get large portable dehumidifiers with a capacity of up to per day.

[ Edit ] Tips

  • While a dehumidifier can help keep a room or a home dry, you make the most of it if you try to keep excess moisture out of your space Firstly. You can keep your home drier by using valves and fans in kitchens and showers, open windows and doors when the weather is cool and dry, and keep your space well-insulated and heated in cold weather. [13]
  • Many central air conditioning systems have built-in dehumidifiers. If you have central AC power and your space is still humid, check with a technician on your air conditioner to make sure it works properly.
  • In general, there is no need to make detailed calculations (such as the air flow rate in your space or the exact volume of the area you want to dehumidify) to determine what type of dehumidifier you need. Just look for a dehumidifier that is rated for size (in square feet or meters) and the moisture level in your space.
