Comfort Zone CZ319WT 9" Twin Window Fan with Reversible Airflow Control, Auto-Locking Expanders and 2-Speed Fan Switch, White

Muy buen producto, enfría rápidamente el cuarto. Solo dos detalles, el ruido, el cual es comparable a otros ventiladores pero sería excelente que pudiesen bajarlo y la otra área de oportunidad, es que le faltan opciones para fijarse a la ventana (quizá Velcro) y eso ocasiona problemas con diferentes ventanas

Super recomendado, parece que tengo aire acondicionado,lo uso por las noches lo tengo empotrado en mi ventana y en menos de 15 minutos logra enfriar toda la habitación del aire fresco del exterior, lo que si recomiendo es dejar la puerta entre abierta para que se haga una burbuja/ambiente frio y se salga el aire caliente al resto de la casa. Si se deja la puerta totalmente cerrada produce mucho ruido por qué el aire no circula

Es buen producto..el único detalle es que no trae botón para invertir el aire...tienes que voltear el ventilador para que haga la función .es decir no lo puedes fijar permanente.porque si quieres invertir el flujo de aire..tienes que cambiar la posición del ventilador.

Me gustó que saca el aire caliente y ventila aire fresco. Debes ponerlo en la orilla de tu ventana para que saque el aire caliente. Muy buen producto se ve como muy simple pero Funciona bien. Lo recomiendo.

This is a decent exhaust fan that performs well for reducing moisture levels (we monitor through temperature and humidity sensors) without significantly affecting indoor temperature, even with the imperfect seal (i.e. fanned pull out extensions on each side of the fan to cover gaps— a brilliantly adaptable design for multiple window widths). It can also function well for blowing cool air in. That being said, if this fan is used daily, it will probably last about a year with upkeep unless you are savvy with mechanics. This is my conclusion after owning about four of these. The reason for the downgrade in stars mostly has to do with this disposable quality. The company offers no support for repair, which is admittedly more common than not for items like this. But there is more. While they did efficiently honor one of our warranties, there was no room for context. They verified the receipt, identified that it fell within the one year time frame, and sent a new fan. However, they did not verify the model type (we initially purchased the three speed) and sent us the incorrect model (the two speed). While the price difference is small, our purchase decisions are well-reasoned. I emailed a couple of times with a week span between emails. I received a auto-verification that my email was received and no response despite their initial quick responding to the warranty request. It would seem that the company did not care to engage with the humans that purchased the fan or to attempt to resolve their error.
