HUGOOME Open Size 9.5"*9.5" Exhaust Shutter Extractor Fan 500m³/h, 2-way Reversible Strong Airflow Wall Mounted Vent Fans, Ventilation Blower for Bathroom Attic Window Basement

A great little device. I added a simple l-shaped aluminum bracket and now have this secured in my window where its pull cord, allows you to blast extra air in, or expel air out. Clue. it i better to expel the warm air. I have it plugged into a remote control socket so it works at the touch of a remote. Edit. This is 16 months later, and i feel like i want to give this another star, 5 stars aren't enough for the relief provided by this fan. I had another fan where the motor unit was separate from the vent, and where to reverse the airflow you have to disconnect the hose and physically turn the motor around. This for the price is incredible. As well as easily changing the direction of the airflow, it will also close the vent in its 3rd position.

Working good as mentioned in the description and good quality.

Seems very good fan, a bit noisy , it does not have electronic shutter. Time will tell how long it last.

I needed a solution to smoke in the studio, I tried 4 inch” inlet and exhaust, seemed to do nothing. Installed this into the inlet I was using and now the room clears out in a matter of seconds, Not loud imagine a desk fan Simple fitting and not brittle, Fantastic

After a couple of months, it broke. I'm just frustrated, to be honest. The click button that turns the fan on and off stopped working. I always maintained it, cleaning and removing all the plastic front parts to clean. I really didn't expect that. Very frustrated.

I bought this to replace an experair that we had for years but I wanted one that could be reversed when needed. Had this about 3 months and in the last few days it just decided it had had enough. Contacted seller and it was replaced within 24 hours. Can't say for sure this one will work but can't fault the sellers customer support.

I get it it's larger than usual, it produces sound when in operation, but it's effective, I'm not sure where others are using it, but I purchased this to fit in my cellar/basement to kick out the moisture and move the air about. Once it's switched off, it closes the flaps outside so no air comes from outside, when you switch on flaps open automatically.. I would have loved to have it in the bathroom, but my walls are tiled and it will be a lot of work to break a bigger square hole for it, however in the basement it was only brick. Easy to break wall in shape. This would have been perfect for steamy shower rooms. Works in two directions in case you need fresh air in, pull cord works perfectly. Price is great, better than the small ones designed for bathrooms but don't do the job, not sure why lots of ppl concerned about noise more than effectiveness of the product. Looks good too. Installation was easy too. No complications, just pull cord to start it!

I installed it in my kitchens window by removing double glazing. It has a good capacity. Getting all the cooking vapour out. It is strong enough to open your kitchen door if door is not latched. Reverse direction is not the best though as the shutters disturbs the air flow going to the fan and reduces its flow capacity. Not sure about reliability as it hasn’t been much after installing. I will update this if any issue appears.
