Product Overview

AlorAir 70 Pint Energy Star Crawl Space Dehumidifier
With global energy demand and CO2 emissions on the rise, the Sentinel HD35P dehumidifier improves energy efficiency, lowers energy bills, and reduces greenhouse gas emissions without sacrificing performance. When choosing a dehumidifier, look for products with ETL and Energy Star certifications. ETL certification represents compliance with North American safety standards, and Energy Star certification ensures that the unit operates with the lowest energy consumption. AlorAir designed this 70PPD dehumidifier specifically for modern homes and can be used in spaces up to 1,000 square feet. The built-in condensate pump pumps water up to 19.6 feet, while the included drain hose allows for easy gravity or upward drainage. So you'll have peace of mind knowing it'll continue to provide you with a healthy living environment.

1. Prevent mold and musty odor - Molds are caused by moisture in the air and spread easily. They can grow on wood, pipes, carpets and even wallpaper. Once grown, they're very difficult to remove. That's why it's important to have dehumidifiers that reduce the moisture content of the air by drawing out excess moisture. The humidity in your home is already too high? Then an AlorAir 70ppd dehumidifier can help speed up the drying process.

2. Reduce condensation - If condensation or water droplets are forming on the inside of your windows, it means the humidity in your home is too high. Over time, this can cause your home and furniture to soften and rot. Condensation is more likely to occur in the winter because there is less ventilation. This dehumidifier can operate at up to 33℉ and help you control humidity and condensation.

3. Lower Energy Costs - Since the dehumidifier reduces humidity, you won't have to turn on your air conditioner as often and your cooling units won't have to use more energy to maintain the desired humidity in your home. Plus, the Sentinel HD35P dehumidifier is Energy Star certified, so it uses less energy to run, saving you even more.

4. More Comfort - High humidity not only makes it difficult to breathe, but it can also cause additional respiratory problems that make life very uncomfortable and annoying. With a dehumidifier, it's easier to keep the humidity in a range that's comfortable for your body, so you can have a comfortable living experience.

Dampness and water stains appear on the walls and ceilings, musty odors spread throughout the rooms, condensation covers the windows, and mold creeps up wooden furniture and ceilings with the naked eye. We know how annoying this can be, which is why we offer an Energy Star and ETL-certified dehumidifier to provide you with the relief you need.

The AlorAir Sentinel HD35P has an adjustable humidity range of 25%-80% that you can control from the control panel or our optional remote control, whichever you prefer. The unit automatically shuts off when the humidity reaches the set level. You can safely use the unit when you're away from home or in an unoccupied basement.

After a power outage, the unit will restart; and at low temperatures, it'll activate the automatic defrost function and turn off the compressor and keep the fan running if the internal components freeze. Plus, you'll know when defrost is in progress by the illuminated light. You can easily place the unit in your garage or warehouse to control humidity for you.

Quickly and efficiently removes 75 pints of moisture per day at saturation.  And with GLGR technology, you'll save 30% energy with precise humidity control.  And for that, we've received Energy Star certification. Whether you use it for drying furniture, painting, laundry, or quick drying in construction, it's a money-saving option.

We designed this small, portable dehumidifier for up to 1,000 square feet of space, while keeping the noise level below 55 decibels. It's also suitable for daily dehumidification in small restaurants, stores, machine rooms and other environments.

Note: there are two drainage modes
1. When using the pump drainage mode, you must press the "Drain" key, connect the drain pipe to the drainage port under the filter and block the gravity drainage port.
2. When using gravity drainage mode, turn off the "Drain" key and connect the drain pipe to the frontal drainage port.

Super Product, Great value Very easy to use

I purchased this model to use in my workshop, about the size of a large two car garage. My first impression of this was how well it was packaged with no chance of damage during shipping. I was pleased to find easy to understand instructions on use. I temporarily set this up with the gravity drain until I have time to mount it and use the pump drain feature. They do include both size drain hoses. Another great feature is the "memory start" feature which restores your settings after a power outage. The instructions were very simple to read and understand. This unit is very quiet and rated at 55 decibels. Being energy star rated is another plus.
Good buy

Great Dehumidifier in a small package

I own a Mold Remediation and Water Restoration company and we use several Dehumidifiers. Some of them are quite large and will not fit in spaces that we need to. I found this Dehumidifier on Amazon and it looked like the perfect size for our crawlspace work. I just received it last week and we had an opportunity yesterday to try it out, It is the only Dehumidifier that we have that fit through this crawlspace opening in the floor, we were also lucky that the drain hose and power cord are long enough to reach the only outlet we had available to us outside of the crawlspace. It operated fine all day long, did not take up very much space and my guys said they had no problems getting it in and out of the opening. I will definitely purchase another one to add or our equipment stock.
I love this new dehumidifier.

This dehumidifier is compact but yet powerful. I have several customers in my line of work that I ordered these units for. They help control mold in your home by reducing the humidity.
