Dehumidifiers

Dehumidifiers remove excess moisture from indoor air to support humidity control in commercial facilities, industrial operations, homes, storage areas, crawl spaces, and other enclosed environments. Products in this category are used to help limit condensation, mold growth, and corrosion, while supporting lower-humidity conditions for applications such as manufacturing, packaging, restoration, and storage.

Choose a Dehumidifier for Your Space and Moisture-Control Plan

The products represented here range from compact desiccant units for difficult-to-reach spaces to portable commercial models, wall-mounted units, whole-home systems, and high-capacity industrial equipment. Start with the area being treated, the required moisture-removal capacity, installation approach, drainage needs, and available electrical service.

Use Cases

Match the unit to the environment

Commercial and industrial models are represented for offices, laboratories, warehouses, storage rooms, locker rooms, computer rooms, pumping stations, and restoration work. Whole-home units are represented for homes, basements, crawl spaces, townhomes, and condominiums. A compact desiccant model is also represented for boats and other tight enclosed areas.

How to Choose

Compare capacity, installation, and power

Compare stated water-removal capacity, from 25.4 pints for a compact boat unit to 562 pints per day for an industrial desiccant unit. Confirm whether the model is portable, wall-mounted, hardwired, venting, duct-capable, or intended for a permanent installation. Also check the stated 110V, 115V, 120V, 220V, or 460V electrical requirement.

Applications

Plan for moisture and temperature conditions

For low-humidity manufacturing, packaging, or hygroscopic-product storage, consider industrial desiccant dehumidifiers. For low ambient temperatures, represented options include temperature-sensitive defrost, hot-gas defrost, reverse-cycle defrost, and low-temperature operation. Some products also provide humidistat control for setting a preferred dryness level.

Additional Information

Consider drainage, movement, and maintenance

Pump-equipped models move collected condensate as part of operation, while other products use a gravity drain connection or a threaded drain connection. Portable options may include wheels, handles, casters, a folding handle, or a drain hose. Washable filters are represented on select units, and one compact desiccant model vents moisture outdoors as nano mist without a collection container.

Planning Guide

Plan the right fit before choosing

Plan the space

Define where and how the dehumidifier will operate

Identify whether moisture control is needed in a single room, a tight work area, a large residential space, or an industrial process or storage environment. Represented products address room-size areas, wall-mounted applications, whole homes, crawl spaces, and demanding indoor facility locations.

  • Whole-home options are represented for homes, basements, and crawl spaces.
  • A 130-pint whole-home model is sized for residential spaces up to 7,200 square feet.
  • Wall-mounted moisture control is represented for offices, apartments, stores, restaurants, salons, museums, garages, cellars, and animal enclosures.
  • Industrial desiccant units are represented for manufacturing, packaging, and storage of hygroscopic products.
Plan installation

Check placement, drainage, and electrical requirements

Installation needs vary considerably across the category. Some units are designed for movement between work areas, while others provide wall mounting, hardwired operation, venting, permanent mounting, ducting capability, or flexible air-discharge orientation.

  • Pump-equipped models help manage collected condensate; one portable model moves condensate upward up to 20 ft.
  • A 56-pint portable model includes a 16 ft. power cord and 25 ft. drain hose.
  • A 70-pint whole-home venting model has a stated 22 x 30 x 20 in. footprint.
  • A high-capacity industrial desiccant model uses 460V hardwired operation by a licensed contractor.
Plan operation

Select controls and features that fit day-to-day use

Compare automatic or manual modes, adjustable or electronic humidistats, digital displays, fan settings, defrost methods, and monitoring features. These features can help users set dryness levels, observe operation, and adapt the unit to the environment.

  • Automatic digital controls and displays are represented on whole-home models.
  • Some industrial desiccant models offer automatic or manual modes, electronic controls, remote humidistat capability, and a built-in ammeter.
  • A commercial model records operating time on its digital display, while a portable model includes an hours-run meter.
  • Select units offer washable filters, and one commercial model can stack up to three units high for storage and transport.
