Comfort Zone CZ310R Twin Window Fan

This fan works very well. As you can see from the photo, my window is very old and busted, so I needed to add some tape around the edges to keep bugs out. I primarily bought this fan for two reasons: 1. Vent the hot air out of my room. 2. Vent cigarette smoke outside. This fan succeeds on both. Keeps the room nice and cool while also keeping the smell of smoke out. It's a *little* bit louder than other fans I've had, but it's not extremely loud. Installation was very easy, the one caveat is that the locking adjustable sides can be a bit... finnicky. My window is very wide, so I needed to extend them to their max size, and the locks kept unlocking with the amount of pressure the sides were producing inwards. However, I got it installed and it's now working great. The remote works out of the box. It takes 2 AAA batteries (not included). I'd recommend this fan for anyone who wants to keep their room cool, or vent cigarette smoke.

This fan works very well, gets the job done, and easy to control with buttons or remote. The twin blades bring cool exterior air in, or take interior air out, or both at same time, which is the biggest positive, without manually having to lift and rotate the machine. The size is 23 ¾ x 12 x 3 ½ inch and fits inside the side sliders double window panes track or in front of the interior front pane on window sill. The two legs attach by a clip and supplied screw on bottom and is another useful positive and prevents fan from falling or blowing over if sitting against the window, or on a flat surface. Fan has a moderate weight, hand carrying indentation, and stable white plastic frame. Comes with elastic bug screen cloth filters for front or back side of fan frame and used only when fan is off. The only three minor negatives are the buttons on the grey front control panel are impossible to see to activate, but the remote is easy and effective from five feet away; the on/off/changing buttons have a very loud chirp sound; and the fan motor (not the blades) has a slight hum sound. This is an excellent fan, at a very competitive price. Highly recommended.

Ha sido la mejor compra para estos tiempos de calor pues puedo jalar el aire frío de afuera ya que un ventilador normal no me era suficiente para refrescarme con estos calores. Me encanta que tiene el control remoto y que tiene la opción tanto de sacar el aire caliente de mi habitación o bien, jalar aire frío de afuera hacia mi cuarto. También tiene la opción para reciclar el aire. Otra ventaja que me gustó es que puedo ponerle las patitas y lo pongo frente a mi cuando trabajo en la computadora, en caso de que necesite aire directo o que esté lloviendo. Hay otros ventiladores de ventana que no traen estas patitas y no podía ponerlo frente a mí. Esté sí tiene esta opción. No es ruidoso. Puedo dormir tranquilamente.

Pros: -full featured unit with remote control that works -everything worked right out of the box - no issues with any parts or remote -generally well designed and fit the window as expected - not a perfect window seal none of these units are you'll have to add your own insulation -very quiet - you can sleep with it no problem at all -moves air in accordance to dual twin 9" fans - good for spring and fall not for hot summer Cons: -really I don't have any except the same that would apply to any window fan - that is to say, you can use it as an exhaust when the room is too hot or as an intake when the outside temperature is cooler that the indoor temperature, but to leave it as a permanent mount when it's hot outside and cool inside is completely counterintuitive since the unit is not sealed and does not come with any sort of cap to cover all the opened grating therefore let's heat in - I remove it from the window and close the window altogether but it's an inconvenience as is with all window fans Overall I highly recommend this unit thus far (don't know how long it will last) this is a very good spring and fall unit but will not help you much/at all during the summer - even as a twin 9" blades simply can't move enough air to make a difference during a hot summer day

I like it a lot , just a little loud on high , not a deal breaker
