Best Thing I Have DonePackage Quantity: 1| Portable Air Cleaner with HEPA Filter is Whisper SoftPackage Quantity: 1Why do people expect silence?To All Those Who Complain About This Being LoudPackage Quantity: 1|Note: If you can hear the button presses in the video... your video player volume is quite high... turn it down a bit! Also note, my recording equipment (my Razr Maxx) is quite sensitive to be able to pick up my breathing and the button presses...This is just a video to record the different volumes coming from this unit at High, Medium, and Low.I personally don't think that High is loud though I can understand that to some people it is loud. But come on, it's a blowing air from the top at high speeds!It's like a fan, and it definitely cools the room so put on your sweater!Also in the video is how Medium sounds... be sure to note the decrease in volume from High to Medium... big difference, yes?Still, to me at least, not loud, bearable... do you know what is more annoying? Babies crying... or should I say... cry babies... *wink* just joking... again I understand that some are sensitive to noise... but gardeners and some sprinklers cause more ruckus than this trusty little unit!
It purifies your air!Last but definitely something to note is the volume on Low. Be sure to notice the change from High, and from Medium... Low isn't loud at all!My PC is louder than that! And under load, my PC is nearly as loud as High! (My PC has 6 fans not including CPU/GPU/PWR).I'll have to come back to this review to comment on the unit's effectiveness and HOW I FEEL ... as of now it's been running constantly in my room ~ 160 square feet for about 2 hours... and I just took a deep breath... I can breathe again!Ok this is an update, it's been running for over 9 hours now... I actually totally forgot about it because I was distracted watching movies, playing video games, and guitar...I also forgot to add that it's light weight. It can easily be transported...Does the job, but rather noisyPackage Quantity: 1Functionality Versus QuietPackage Quantity: 1|Received this product on January 8th, 2012Package Quantity: 1 Yes, it is noisyPackage Quantity: 1|Legacy technology, that is loud, and the company no longer makes full replacement HEPA filters - unit has a life of one yearPackage Quantity: 1|
