I've owned these fans for about 10yrs, the 953 primarily and a few smaller ones. I've only had one fail however, it was subject to drywall dust and moisture. This fan is Made in the USA and the craftsmanship is very different than the 953, the plastic housing density is thicker and the motor itself appears more precision and heavier duty than the 953. The metal stand has a good feel meaning, not thin metal. The fan must be attached to the stand, IHMO they should do this at the factory. The power cord is a three prong end and the cord itself is a thicker gauge than the 953. The airflow between the two models is comparable and the fan noise is about the same.

I will be purchasing the 293 over the 953 in the future, the main reason is Made in the USA and the motor. As noted, i've own the 953 for years and these fans run 24x7 in my house and i've only had one fail so, i'm hoping the 293 gives me the same reliable service.
