## Questions & Answers

**Q: How easy or difficult is it to disassemble for cleaning?**
A: No assembly needed.  I haven't had to clean the one I have other than to dust off the outside - I don't think there is a way to get to the fan blades to actually wipe them down.  It's great to set in an open window at night!

**Q: Why is this double the price? It’s $18 at Walmart**
A: It’s possible that the fan at Walmart LOOKS like this (Don’t all box fans look about the same?), but Walmart is known for sourcing items that are of lower quality, but look the same, to give the appearance of being a lower price for the same item. 

A possible big difference- check the CFM air flow (they probably don’t tell you that on the box).  The lower end fans run as low as 1400 CFM, while the higher end, like the Hurricane, move up to 2400 CFM

**Q: What's the cfm on high and low speed for this fan?**
A: It has a CFM of 1200 on low and 1820 on high.

**Q: I'm a member of prime why am I being charged shipping charges?**
A: I don't use FBA so prime isn't included on my products.  I do however Lower my price so that it is even cheaper than prime.
