I have been using the Hoover WindTunnel [amazon.com]
(UH72400) for last 6 years without any issues. I was looking to see if there are any Prime Day deals on the filters and saw that Amazon has it for $90 only if No Rush Shipping
is chosen at the checkout.
I bought it for $145 so I think this is a great deal.
also has it for $90. I am not sure if you get additional 5% off with RED Card but that would be even better.
