Dyson Air Multiplier? table fan - 10" whiteI,m a product and design engineer by trade , and have years of experience , We live on Cape Cod and
do not use air conditioning during the summer, when its hot we use table fans and window fans and have
about 4 types that we use around the house to keep cool on the hot days and nights.
When I saw the Dyson 10" ring fan on a show room floor it seemed to move the air well , and did not seem noisy.
I then purchased the product and when I received it and and took it out of the box it moved the air well but
was very noisy on low speed and has a constant "loud" 500HZ tone that everyone in the house can hear , even in
rooms at the far end of the house on a quite day or night . This 500 hz Noise is not something you get used to and
compared to some of our other bladed fans running on slow , the Dyson Ring fan is very noisy .
Until Dyson fixes this problem , the product will not serve much purpose as we have our's switched
off do to the noise , it's now acting as a $300 dust collector , which it seems to do very well.
I can only say that for the price I expected more from Dyson , I would not recommend this product to anyone, do not buy
this product unless you have a house or building with a lot of background noise like in a city , In fact maybe
Dysons lab is in a noisy building in down town London . I give it a very Bad rating due to the Noise it makes.
