The Hammacher Schlemmer Institute's tests reveal the one Low Profile Window Fan that can, in its opinion, be called The Best. The Institute forwards its recommendation to Hammacher Schlemmer's buyers so they can procure the product for The Hammacher Schlemmer catalog, web site, and retail store. The Low Profile Window Fan that is currently The Best can be found here.
Before undertaking testing, The Hammacher Schlemmer Institute surveyed consumers to learn which attributes are most critical when purchasing a Low Profile Window Fan. They responded that Air Velocity is by far their most important concern, followed by Noise level, Ease of Use, and Features. These attribute rankings were applied to the data collected for this test.
Respondents were also asked which features matter most in a Low Profile Window Fan. Based on their answers, The Best model must have twin fans, be 12” or under in height, and have adjustable speeds.
The Hammacher Schlemmer Institute then researched the marketplace from a reasonably wide range of competing product and obtained Low Profile Window Fans that possess these desired attributes and features. Prior to testing, the Institute eliminated from consideration any models that did not have a required attribute or feature or if it had an obvious quality issue. Conversely, if a sample offered a unique benefit that distinguished it from other models, The Institute, at its discretion, may have included it in testing even though it may have been lacking a critical feature or attribute.
Testing involved evaluations by Institute analysts. Each Low Profile Window Fan was rated for its Air Velocity, Noise Level, Ease of Use and Features.
The Hammacher Schlemmer Institute used a digital anemometer to measure wind speed at different speed settings. Wind speeds were measured at different distances from the fan at 3 different positions on the fan. The maximum speed at each speed setting, at each distance, and at each position of the fan is recorded. The analysts also consider the air volume of each unit.
Analysts then took the average of the scores and determined a final Air Velocity score.
Analysts used a decibel meter to gauge the sound output of each fan. They begin by first testing ambient noise in the room with the fan off. Then tests continued at their lowest, highest and medium speed settings (some models have additional speed settings which are not considered) and are taken at different distances from the fan.
For each Low Profile Window Fan, analysts determined how easy it was to:
Analysts assigned a score each step, with lower scores indicating a process was very difficult and higher scores indicating it was very simple. After testing, analysts calculated an average ease-of-use score for each Low Profile Window Fan
Institute analysts inspected each sample to determine whether it had any of the following features, which made a Low Profile Window Fan easier or more effective to use:
Analysts awarded points for each feature that a model had, weighted according to how important that feature was to consumers. After testing, they calculated an average features score for each sample.
The Hammacher Schlemmer Institute recommends that you consider these features when shopping for a Low Profile Window Fan to ensure you will be completely satisfied with its performance:
A window fan cools a room down with a flow of natural, fresh air, something many consumers prefer to the noise and expense of operating an air conditioner. But even a simple solution is inefficient when using the wrong tool. An oscillating fan propped near an open window cannot create enough suction to draw air in, while a precariously perched box fan on the sill is ill-fitted to the space, leaving a gap that ruins the greatest advantages of proper window fans. Low profile fans solve this problem by sitting securely in a minimal window opening, with expandable side panels that adjust to seal the gap. Positioned in this unobtrusive way, window fans also achieve a customized environment in a room: Not only can they draw cool air in from outside; their fans can often be reversed to exhaust hot, stuffy air out. Likewise, reversible fans can allow one fan to draw in while expelling out, creating an air exchange that manages room temperature with the refreshing atmosphere outside.
As with any product, customers must read and follow the product's user guide, marking and labeling prior to use.

Although funded by Hammacher Schlemmer, the Institute functions independently of Hammacher Schlemmer. The Institute consults Hammacher Schlemmer and fulfills its mission statement without regard to product prices, brand names, margins, or other commercial considerations. Decisions on specific products to test, the types of test to perform and how to interpret the results lie exclusively with the Institute's research staff. In addition, the Institute's status as a separate entity from Hammacher Schlemmer prevents access to sensitive information, such as inventory levels or product cost, which might influence testing decisions. The Institute's independence assures products are researched, evaluated, and rated objectively without commercial bias.
