AirMop III

Products

The AirMop line of high capacity, energy-efficient, free standing dehumidifiers are designed to provide the ultimate in humidity control for basements, crawlspaces and living spaces.

Ventilation of a basement or crawlspace to control relative humidity (RH) only works consistently in an arid climate. In most climates, ventilation can add significant quantities of moisture during humid times, but the AirMop can help.

Depending on the outside weather, as much as 375 pounds of water per day can infiltrate a basement or crawlspace through powered ventilation.

Consequences of High Humidity in Basements and Crawlspaces

  • Wet basements and crawlspaces contribute to the cupping of wood floors and the deterioration of floor joists, beams, sub-flooring, insulation and electrical-mechanical systems.
  • Excess moisture encourages mold growth on wood and on any other organic material in a basement or crawlspace.
  • Basements and crawlspaces are a major source of air infiltration that permeates up into the living area, transmitting odors, carrying moisture, and creating and environment conducive to molds and dust mite infestation.

Be Proactive!

Proactive dehumidification of a sealed basement or crawlspace is the only way to ensure desired humidity levels are present. We recommend taking the following steps:

1) Seal all outside vents and windows to eliminate outside air, which also reduces heating / cooling loads and uncontrolled moisture intake.

2) Install vapor barriers over exposed earth in a crawlspace.

3) Condition the basement or crawlspace with an AirMop® III to provide humidity control regardless of the outside conditions.

Large Capacity Dehumidification

The cooler temperatures in basements and crawlspaces create unique humidity control challenges for homeowners.

The earth under the soil in a basement or crawlspace remains at a near constant temperature of 50-60°F year round. The ground keeps the surface soil in a basement or crawlspace cool. These cool surface temperatures create micro-environments where the relative humidity of the air approaches its saturation point (100% RH) and condensation or “sweating” can occur. The resulting conditions support mold / microbial growth and cause musty odors.

Often the only way to maintain the EPA’s recommended humidity levels for homes of 50% RH or less is by running a high capacity, high efficiency dehumidifier.

Capacities for residential dehumidifiers are measured in pints of water removed per day at standard conditions. Standard conditions are determined by the American Home / Appliance Manufacturers Association (AHAM) and are used because capacity will vary under different conditions. AHAM standard rating conditions are 80°F and 60% RH. The capacity of the AirMop® III is 90 pints per day! Most standard residential units range from 20 to 65 pints of water removal per day. However, most basements and crawlspaces are cooler than 80°F and therefore the water removal capacity of the standard residential unit will be diminished significantly.

A large capacity dehumidifier is necessary to ensure that enough moisture is removed at the real world temperature of your basement or crawlspace to prevent mold, mildew or bacterial growth. The AirMop® III is a large capacity dehumidifier designed for these cooler situations.
