AlorAir® Sentinel HD90 Basement & Crawl Space Energy Star Efficiency Dehumidifier


AlorAir® Sentinel HD90 Basement & Crawl Space Energy Star Efficiency Dehumidifier




Humidity is one of the most underestimated problems in the household. Even if it’s not perceptible, it can cause catastrophic damage to your home or business and to your health. Moisture problems are common in basements, crawlspaces, and other areas where water vapor can accumulate, such as in spaces under the roof.

Not having a way to control humidity allows mold to grow easily. The result is higher maintenance cost, property damage, poor air quality, and lower property value. It is also the culprit in many cases of health problems. The dust and water vapor in the air tends to cause allergies and other health problems to humans when seen accumulated in large quantities.

Take control and reduce humidity to remove these risks and protect your loved ones and your potential investment.

The AlorAir® Sentinel HD90 Basement and Crawl Space Energy Star Efficiency Dehumidifier is one of the appliances that can be relied on to control humidity from the surrounding or any other section of the house by removing excess moisture in conditions where the humidity is unsafe.

The main purpose of this device is to extract excess moisture from the air causing mold, mildew, odor, condensation, etc. It does this by removing water vapor and humidity from the air using ion exchange. This process takes place when a negatively charged corona wire attracts moisture in the air, leaving dry air behind. It also reduces asthma symptoms caused by asthma triggers like mold, mildew, dust mites, and other irritants.

This device regulates the humidity levels without being loud or obtrusive. It can be placed in basements and other lower-level areas where high humidity is a problem and help you take control of your situation. An optional remote control is available for purchase so it can be placed in hard-to-reach areas.

Functions of the ALORAIR® SENTINEL HD90 Dehumidifier

1. It can be deployed to lower the humidity in your living and working spaces and make them habitable. If you are living in areas with high humidity, you need a basement and crawl space dehumidifier to control and regulate the humidity levels.

2. For those of you who live or work near a quarry, the air around you may contain millions of particles of stones. This could be a health hazard. So, you need Sentinel HD 90 to remove the particles. This is critical since it ensures that you remain healthy.  

3. If your house or business is poorly ventilated, a dehumidifier will help to clean the air and allow you to breathe fresh air.

4. People who live in apartments must have a dehumidifier in their houses to control mold and mildew spores. These allergens travel through ventilation systems and will always hide and build up in walls in apartments. They may pose great health risks to the members of your family. As such, having a working dehumidifier will keep the allergens at bay.
