Typical "Made in China" product - good price, cheap materials. Oh yes, and if you don't see the loss of performance, you don't know your vacuum cleaner well enough. Let's just say the original filter (which is over 1 year old) that came with the vacuum cleaner sounds and works better than this new "replacement" filter. I'll send the replacement back and order the original. My $600 vacuum isn't worth the cheap filters and may endanger the motor. Happy shopping and as always, be careful!
