Amazon Basics Window Fan with Manual Controls, Twin 9-Inch Blades

Me agrada mucho en poco tiempo limpia olores

You can hardly feel the air from this unit with both fans blowing let alone when you have one going each direction. Box fans are cheaper and provide much more air flow

No bells and whistles, and none needed. This is a workhorse fan at an excellent price. We bought two for kitchen windows and, with advent of coronavirus and smoking neighbors, set them to blow air out. They have been working all day every day for months, now in high temperatures, with no issues. The noise level (again, given the neighbors) is manageable. Our only complaint, as with all fans, is that the blades get dirty and theyll have to be cleaned at the end of the season. For now, theyre champs.

Trabaja bien y el ruido casi no lo notas
