Twin Window Fan with Reversible Airflow Control, 9 inch, Auto-Locking Expanders, 2 Speed Fan, Dual Fan, Exhaust, Airflow 9.84 ft/sec, Ideal for Home, Kitchen, Bedroom & Office, CZ319WT

NICE! We live in a little studio apartment and there is no vent for the stove/oven but we do have a window right there. We use to set the fire alarm off any time we cooked and the house would fill with smoke. I could deep fry chicken wings on the stove top with this running and the house wouldn't smell at all when I finished, it's that good! Flows a ton of air out so I'm sure it does the same in. We remove it from the window after we cook but it is nice the sides come out to fit better and the bug net thing is nice too

This window fan provides strong airflow and helps circulate fresh air effectively. Installation was simple, and the adjustable panels fit well in standard windows. The dual fan setup allows for intake or exhaust, which is helpful depending on weather. It’s a bit loud on the highest setting, but performance is solid overall. A good choice for improving ventilation.

I’ve been very happy with the Comfort Zone Twin Window Fan with Remote Control. It moves a surprising amount of air for its size and does a great job pulling in cool air or exhausting warm air depending on the setting. Installation was straightforward, it fits well in the window, and it runs quietly enough to use day or night without being distracting. The remote control is a great feature and makes changing speeds or modes super convenient from across the room. My only minor complaint — and the reason for 4 stars instead of 5 — is that the remote itself doesn’t show which setting is currently selected. The indicators are only visible on the window unit, so you sometimes have to look over to confirm the mode (Cool, Exhaust or Circulate or fan speed). That said, it’s a small issue and doesn’t take away from how well the fan performs overall. Solid build quality, good airflow, and very effective for cooling and ventilation. I’d definitely recommend it and would buy it again. I live in a 55+ apartment where the only the bottom window opens, otherwise I would have put it up higher. Overall, very pleased with it.

Used to reduce carbon dioxide in home office. We kept getting headaches in small home office where we work and play games. Bought a CO2 monitor only to realize we were getting to levels of 1500-1600 and anything over 1800 is considered pretty bad! Bought this. Light weight, fit in window easily (didn't need feet, fit in window sill without removing window screen). First day was in office- In 2 hours use on exhaust on medium, CO2 went down from 1500 to 600. Second day, tried it in bedroom window directly across hall in window on farthest wall on medium. In 1.5 hrs CO2 went from 1200 to 750. Have gotten it as low as 500. CO2 rises from breathing as well using gas appliances (we have a gas stove). Prefer it in bedroom as it is a little loud for me (easily over stimulated by noise). But it isn't so loud you can't hold conversation or anything. Light weight enough that I just take it out of window at night and set it on the sill or floor. Air in rooms definitely feel less dense and more fresh. Very happy with this window fan unit! If you're getting headaches in specific rooms at home, consider it might be CO2 and get some ventilation asap!

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.

This fan is awesome. We have a very hot room with little airflow, and we have been sleeping really poorly lately. We installed this to bring the cold winter air in, and it works so well. Fits perfectly in our double hung windows.

Works great! Fits different size windows. Powerful but quiet. Did not use the bug guard bc it cuts the air flow down a bit.

Overall really nice and moves enough air to cool down and ventilate an average size bedroom. It will bring down the temp several degrees once the temp outside is at or below room temp, and it keeps the CO2 levels around 500-600 with one person in the room (quite good for anyone unfamiliar with IAQ). The remote is a nice feature, and as someone who likes white noise, the fan speeds don’t bother me from a sound perspective. I would give this 5 stars except for the deafening volume of the beeps when you change fan speed or direction. Do not plan to mess with these features after anyone in the house is asleep. I don’t understand why they had to be so loud or even exist at all. If there was a way to turn the beeps off this would be a stellar product for the price.

vent a room quickly draws cool air in if you want or can do both at the same time. This is my second one the other one lasted about four years and still works but needs a good cleening lol

El problema es que la toma de corriente va a 120v. El producto no indicaba que iba a ese voltaje. Lo devolví y partí el cable porque ademàs era de cuchilla., e incluía un fusible en el mismo enchufe, otra cosa extraña al menos para mí.

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.

Pessimo acquisto

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
