When comparing jet hand dryer drying time, do not choose by the shortest number on a specification sheet alone. Compare how each supplier defines “dry,” the test conditions behind the claim, and how the dryer performs with the hands and washroom conditions your project will actually have. Airflow, hand position, noise, power use, and user experience all affect whether a quoted drying time is meaningful for a commercial installation.

A practical starting point is to request the test method and, where possible, evaluate samples under the same conditions. Record results at consistent intervals, such as 10, 15, and 20 seconds, and note whether hands feel dry or remain visibly damp. This gives your team a fairer basis for comparing models than marketing claims alone.
A drying-time figure describes a test result, not a guarantee that every user will dry their hands in that exact period. Results can vary with the test procedure, how much water remains on the hands, hand movement, and the dryer’s airflow pattern. A claim is most useful when the supplier explains what counted as “dry” and how the measurement was made.
Some tests may assess residual moisture by weighing hands before and after drying, while others may rely on a visual or practical assessment. These approaches do not necessarily produce directly comparable numbers. Before comparing two quoted times, confirm whether the test used the same starting moisture, user instructions, and endpoint.
Ask suppliers to define the endpoint behind the advertised figure. For example, does “dry” mean no visible water, a particular reduction in moisture, or a result judged by a specific test procedure? If the supplier cannot provide the method, treat the time as a marketing reference rather than a like-for-like performance measurement.
Also confirm whether the number represents a best-case test, an average, or a result from a particular operating mode. Differences in these details can make two apparently precise claims difficult to compare. Requesting the underlying conditions helps your procurement team assess the figure more carefully.
Start with the test method because it determines what the stated time actually represents. Ask for the procedure, the endpoint, and any assumptions about how users place or move their hands. If the supplier provides a test report or internal test summary, check that the product model and configuration match the quotation.
For a fair comparison, use the same endpoint across shortlisted products. If one result is based on “no visible water” and another uses a different moisture threshold, record them separately rather than treating the times as equivalent. This simple distinction can prevent a fast-looking claim from driving a decision without adequate context.
Drying depends on how effectively airflow reaches the surfaces of the hands, not just on how quickly air moves. A jet dryer may require users to insert and move their hands through a defined drying zone, while other designs use a different hand position. Consider whether the instructions are clear and whether a range of users can follow them consistently.
During sample evaluation, check whether water remains around the fingertips, thumbs, or between fingers. Observe the time needed for both sides of the hands to feel acceptably dry, rather than timing only the first pass. A dryer that is quick when used perfectly may be less suitable if its operation is not intuitive for your expected users.
Use consistent conditions when comparing samples. Keep the same handwashing and water-removal procedure, follow each manufacturer’s instructions, and use the same assessment method for every unit. Where several users are involved, record individual observations rather than relying on one person’s experience.
A useful buyer-created protocol is to assess each sample at 10, 15, and 20 seconds, repeating each assessment 3 times under the same conditions. These are suggested comparison intervals, not a universal industry standard or a claim about expected performance. The resulting notes can reveal whether a product reaches your project’s acceptable endpoint quickly and consistently.

Drying time is only one part of washroom performance. Ask for the model’s power information and measured noise data, including the conditions or measurement method where available. Do not assume that a shorter drying-time claim automatically means lower energy use or a quieter experience.
Consider the location and hours of use. A dryer installed near offices, hospitality areas, or quiet facilities may need a different balance of speed and sound than one in a busy public washroom. Compare the full specification and, if possible, assess the unit in a setting that resembles the planned installation.
Installation details can affect how convenient a dryer is to use. Check the required electrical supply, mounting requirements, clearances, and the relationship between the dryer and nearby fixtures. Confirm that the proposed location allows users to position their hands as intended.
Ask about routine cleaning, filter or component maintenance where applicable, and access for servicing. A dryer’s stated performance is less useful if the unit is difficult to maintain or if the installation does not support its intended use. Include these practical requirements in the same comparison sheet as drying time.
To keep procurement decisions consistent, ask every supplier the same questions and record answers side by side. Separate verified product specifications from estimates or claims that have no supporting method. If information is unavailable, mark it as unconfirmed instead of filling in gaps with assumptions.
| Comparison point | What to request or observe | Why it matters |
|---|---|---|
| Drying-time claim | Test procedure, endpoint, and test conditions | Shows whether timing figures can be compared fairly |
| Airflow and operation | Hand position, instructions, and coverage during use | Helps assess performance for real users |
| Power and noise | Documented specifications and measurement details | Supports operational and site-planning decisions |
| Installation and service | Mounting, electrical requirements, and maintenance guidance | Helps confirm fit with the project and ongoing operations |
First, define the needs of the site: expected user groups, washroom location, operating patterns, and any known noise or installation constraints. Then shortlist products with specifications that match those requirements and ask each supplier for the same drying-time evidence. If a claim cannot be verified or explained, keep it separate from documented performance data.
Next, evaluate samples using a consistent procedure and document both timed observations and practical feedback. If a sample test is not possible, request enough technical information to understand how each supplier obtained its figure and what users must do to achieve it. Make the final decision on the complete fit for the project rather than one number in isolation.
At Modun, we understand that B2B buyers need product information they can use in a project comparison. Share your intended application, target specifications, installation requirements, and preferred evaluation process so we can discuss suitable jet hand dryer options and the product details available for review. Clear requirements also help suppliers provide a more relevant quotation and identify questions that need to be resolved before ordering.
For larger or multi-site projects, align the product specification and requested documentation across all shortlisted options before confirming a purchase. Ask about available sample arrangements, configuration details, and supply terms for the models under consideration. These steps help reduce uncertainty between evaluation, specification approval, and procurement.
The best way to compare jet hand dryer drying time is to check the test method, confirm what “dry” means, and evaluate products under consistent conditions. Use timed checkpoints such as 10, 15, and 20 seconds as part of your own comparison protocol, then weigh the observations alongside airflow coverage, noise, power, installation, and maintenance needs. No single advertised time can answer all of these questions.
Your next step is to prepare a common supplier questionnaire and request model-specific specifications and test details for every candidate. Where practical, assess samples using the same users, instructions, and endpoint. Contact Modun with your project requirements to discuss relevant product options and information for your B2B evaluation.
