Thank you for your feedback.
All fans make some level of noise, and we’re sorry to hear that you found the E-Style too loud for your application. When noise is an important factor, we do recommend customers listen to their choices before purchasing (where possible), this way they can be certain the fan will be suitable for them. We are also available via chat, phone, or email if there are any questions regarding the unit and the specifications provided by the manufacturer. If you would like any assistance with the unit, you can reach out to the customer service team via the contact form:
