GE 40 Pint Dehumidifier Review
GE ADER40LP


The GE 40 Pint Dehumidifier (ADER40LP) is an Energy Star® qualified, medium capacity dehumidifier which replaces the highly regarded GE ADER40LN. The ADER40LN was one of the best dehumidifier models for smaller areas and the virtually identical ADER40LP will doubtless be as popular and successful.


While there are few dehumidifier reviews by consumers to confirm this expectation we have little doubt that by sticking with a proven formula GE's ADER40LP will soon have the credentials earned by its predecessor.


Home dehumidifiers are more frequently used to control basement humidity than for any other domestic application and the GE 40 Pint Dehumidifier is entirely suitable for that purpose. It is important to be aware, however, that like most portable home dehumidifiers this model is not suitable for cool basements, below 65°F, and will be most effective in smaller basements due to to its 40 pint capacity.


At present (June 2011) both the ADER40LN and the ADER40LP are available at local stores and from online merchants and due to their similarities your best guide to which to buy will be price. Those who have read our review of the ADER40LN should not be surprised to find that this dehumidifier review is very similar and that we take a favorable view of both units. We are more than happy to recommend the GE 40 Pint Dehumidifier (ADER40LP) to our visitors without reservation.



GE 40 Pint Dehumidifier ADER40LP


Overview


The GE 40 Pint Dehumidifier (ADER40LP) is a compact and attractive portable home dehumidifier suitable for use in smaller basements or any other moderately sized area within your home. It is easy to use with electronic controls and a clear digital display panel. Although not a low temperature dehumidifier the GE 40 Pint Dehumidifier (ADER40LP) can be used without risk of damage in cooler temperatures as it is equipped with auto-defrost to protect it at temperatures as low as 41°F. The water removed from the air drips into a water collection container and can be used to water your plants, although not your vegetables, or in your steam iron. Alternatively the GE 40 Pint Dehumidifier may be rigged for continuous drainage to a nearby floor drain or sump.


When the bucket is full the dehumidifier stops automatically and an indicator light is illuminated on the control panel. The unit is portable and is equipped with casters and a carrying handle. The dried air leaves the dehumidifier through a vent in the upper rear of the casing and the dehumidifier should be located where a free flow of air is assured.


A washable air filter protects the dehumidifier from air borne particles and this should be removed and cleaned regularly. If you are concerned for the environment you will be pleased to know that the refrigerant used is the ozone friendly R-410A, the current standard for home dehumidifiers.


Features


The GE 40 Pint Dehumidifier (ADER40LP) is equipped with an adjustable humidistat, an essential device for managing humidity in the home. Operating like a thermostat the humidistat can be programmed for the level of relative humidity you choose and will cycle the compressor on and off to maintain that level. This ensures a constant level of humidity and avoids wasteful use of energy and excessive drying.


You have a choice of settings, in 5% increments, from 35% to 80% and we suggest a level of 45% to 50% for comfort, protection from mold and to control dust mites. Authorities such as the US Environmental Protection Agency (EPA) and the Canada Mortgage and Housing Corporation (CMHC) recommend a level from 30% to 50% but you will find our recommended level quite adequate, except in colder (sub freezing) weather, and less expensive to maintain.


The GE 40 Pint Dehumidifier (ADER40LP) is a portable home dehumidifier and can be moved easily across smooth floors on its caster wheels. At 35lbs, the weight of a small child, it is not unduly heavy and the average, medically fit person will have no difficulty moving it up and down stairs using the built in top-mounted carrying handle. The compact casing, 10.25 x 19.5 x 13.38 inches, also makes this dehumidifier both easier to carry and to move in cramped spaces.


As the GE ADER40LP is a smaller dehumidifier the water collection container is smaller to match and has a capacity of just 9.5 pints. To avoid the necessity of emptying the bucket once or twice a day the ADER40LP is configured for continuous drainage. A drainage port is located in the casing of the dehumidifier and by attaching a small bore hose to this port the unit can be drained to a nearby floor drain, sump or other outlet. Drainage is by gravity feed so the water will not drain over any great distance and if the nearest outlet is at a higher level it will not work at all.


If you are relying on the gravity feed it will help to raise the dehumidifier a few feet above floor level to ease the flow. If you do not have a convenient drain you may need a separate condensate pump to force the water up-hill or over a greater distance. If you decide to purchase a condensate pump look for one with a vertical lift capability of at least twelve feet, and preferably fifteen.


Another feature of the GE 40 Pint Dehumidifier (ADER40LP) is auto-restart. This feature is not always included with portable home dehumidifiers but if you cannot be there to attend to the unit all the time it is reassuring to know that it will restart automatically if there should be an interruption in the power supply in your absence.


If you look at reviews on other sites (which of course you should) you will see that the GE 40 Pint Dehumidifier (ADER40LP) has an auto-defrost feature which allows the dehumidifier to operate in ambient temperatures as low as 41°F. This is often misinterpreted (occasionally misrepresented) as meaning that the ADER40LP is a low temperature dehumidifier.


Ice forms on the evaporator (cold) coils of a dehumidifier at temperatures as high as 65°F and if it is allowed to remain it reduces performance and will, eventually, damage the dehumidifier. Auto-defrost reacts to ice formation by switching off the compressor, the engine of the refrigeration process, until the flow of air from the room has melted the ice. Its main function is to protect the dehumidifier from damage in cooler conditions.


Obviously the cooler the air in the room the more quickly ice will form and the longer it will take to melt. As the temperature falls below 60-65 the dehumidifier will spend more time defrosting and less time dehumidifying. The result is a fall off in performance and a reduction in energy efficiency. For this reason the ADER40LP is not suitable for cooler basements and a purpose built basement dehumidifier is both more effective and cheaper in the long term. For smaller basements that get very humid in hot summer weather, however, the ADER40LP is as good as any other portable home dehumidifier and better than most.


Like all portable home dehumidifiers the GE 40 Pint Dehumidifier (ADER40LP) has an air filter to catch air borne particles which could damage the unit. This filter performs an essential task and it is important to clean it at the recommended intervals to ensure optimum performance. The ADER40LP incorporates a filter cleaning indicator to remind you when cleaning is due and the air filter is washable and easily removable to make this a simple task, the only maintenance your dehumidifier should need.


There are three fan speed settings available on the GE 40 Pint Dehumidifier (ADER40LP) which allow you the flexibility to choose between the most effective water removal or the lowest noise level to suit your needs and circumstances.


A simple timer is included with the dehumidifier so that you can set the appliance to switch off after two or four hours.

Consumer Reactions


As this is a new model there are very dehumidifier reviews of the GE 40 Pint Dehumidifier (ADER40LP) available at present. On the other hand this unit is virtually identical to its predecessor so it seems reasonable to assume that it will be as well regarded for its performance, build quality and reliability as the ADER40LN.


The GE 40 Pint Dehumidifier (ADER40LP)
Our Recommendation


In our view the GE 40 Pint Dehumidifier (ADER40LP} is one of the outstanding home dehumidifiers in its class and ideal for smaller basements and other areas of your home. Please note that for larger basements you will need a larger dehumidifier and that if your basement is cool the GE 40 Pint Dehumidifier (ADER40LP), or any of the many other home dehumidifiers available, is not a good choice.
