No, quite the opposite.  You missed one of the most salient points of the study.  Despite the vacuum's filtration during operations, once the user removes the dirty bin and dumps the dirt indoors all the vacuum's filtration/indoor air quality is voided.  It's all for nought.  Dirt is back in the air and breathed.  If dumped outdoors, the user is exposed directly to/inhales the dirt from the vacuum.  Lose-lose for both users and household air quality.  Dust/face masks are recommended for the dirt bin dumping and air purifiers for indoor air. 

Excerpt:  ...explains Gast. "That's just when the vacuum is running... what the test doesn't show is just how many particles are released back into the air when the bagless vacuum bin is emptied. It's an indoor environmental disaster! If you can smell the dust after cleaning the bin, you are already inhaling fine lung damaging particles."

I laughed out loud when I read this.  You argue the obvious.  You extol dysons for lasting 7 years and berate cheaper brands for lasting 4.  But of course we expect vacuums priced like dysons in the range of $400-$600 to last 7-10 years plus with normal use and routine expected maintenance.  It's a given when plunking down that much money.  Why is it such a big deal for you about dysons.  From my perspective, and probably others, the earliest model dysons are still only 8 years old at the most in the USA [the brand was launched April 2002 with DC07].  The jury is still out on dyson's longevity and durability at least in the USA.  There are some more years to go before a reasoned intelligent decision based on supportable evidence regarding dyson's quality and longevity.  I find it ludicrous to base any credibility on the opinions you formulated over a few days about a dozen dysons bought off the junk heap.  Along with one dyson you bought for $30 and repaired by vacuuming, wiping down and spraying with silicon lubricant.  If I'm paying $400-$600 for a vacuum, I need more reason than that.  But thanks for the laughs.  They were priceless.

No, quite the opposite.  It proves mine.  This is exactly what people expect when they plunk down $400-$600 US for a vacuum.  7-10 years plus of service with normal use and routine expected maintenance.  Nothing special if the vacuum delivers what's expected.

WRT dyson filtration, it's all for nought as soon as you remove the dirt bin and dump.  Ask any doctor who specializes in patients with eye, ear, nose and throat diseases.  They'll tell you to stay clear of bagless vacuums even dysons.  Bagless vacuums are triggers for the breathing disorders.

Now...who's being biased?  Dysons should deliver exactly what people expect when they plunk down $400-$600 on a vacuum.  7-10 years plus of service with notrmal use and routine maintenance.  That's a given.  Nothing special if it does except in your way of thinking.

Hi Venson;

In the likely/unlikely event that Sir James moves production of dysons from Malaysia currently to say........... Pakistan, this yacht would be the ideal mode of transportion to do so.  For workers who want to go and the whole kit and kabudle of dyson production.  Accomodates 358 plus a crew of 50.

You have not paid full price for your dysons and not purchased any new.  Just bought yours off the junk heap at junk prices.  To make a statement that they are worth the money means that they are worth their prices purchased when new.  You never bought any new dysons, did you?  I have bought both new/used dysons and received several free for extended times to use.  If you sincerely felt dysons are not overpriced and worth the do re me, you'd buy one/more new at the new prices and then make such a statement.  You didn't.  You don't believe based on your actions that dysons are worth the money, except junk prices.  As the saying goes..........put your money where your mouth is.
