I placed this thing on my desk, turned on the UV light, set it on medium fan speed, closed my door and left for a few hours. When I came back, my room smelled fresh and clean. The air felt lighter and easier to breathe. I was amazed. The is a slight plastic smell associated with this device at first, but it subsides quickly. The difference this thing makes, as an allergy sufferer, is night and day. I get better sleep at night and am less congested during the day. That, right there, makes this purchase totally worth it for me.
I changed the filter recently after figuring I could extend the life of the filter by vacuuming it a little each month. I discovered that 6 months, in my case, is the longest I should go without changing a filter. The difference between the new and old filter is astounding (and kinda gross). Seeing these results makes me even happier that I bought this product.
Be aware, some may say that it runs a little loud. Personally, if I were to move it into my bedroom and had it on the lowest setting, it wouldn't be too loud for me but I can see how it may be for others. If noise is an issue for you, find a different purifier.
UPDATE #1: 12Jan2015
I have used the UV-C function and notice very little difference in its current environment. I run this purifier 24/7. Stand by my 5-stars so far.
UPDATE #2: 31May2015
I've knocked the dust out of the filter a couple times since my last update and have kept it running nonstop since I initially review the product. Still awesome.
UPDATE #3: 05July2015
I knocked out the HEPA filter yesterday and it was pretty packed with dust and the like. I take this as a good sign that it is still operating well. The recommended time to replace the filter is near upon me so I ordered another one that should be here tomorrow but I won't replace it yet because I don't think that it is necessary after the clean out. I decided to get one so I would have it on hand when I do decide to replace. Still 5 stars.
No more updates will follow unless it explodes.
UPDATE #4: 16March2016
So I lied; an update and yet the purifier did NOT explode yet. I changed the filter at about the one year mark after several cleanings to the initial filter. Some months ago I dramatically decreased the time that the purifier is running in a given day because it just doesn't seem necessary any longer. Recently (and I mean within the past few days) the purifier's three different fan levels have sort of leveled out. I mean to say that the LOW setting is an awful lot like the MEDIUM setting and not much different from HIGH either. I've had this happen to my automobile fan in the past. In this case, I think that some resistor(s) stopped working (well, anyways) so the fan is receiving near the same electrical current no matter the setting. The UV bulb has gone out but that might be normal for the amount of use it has seen. Strongly recommend this company. When this baby goes out, I'll be going with GermGuardian again.
Update #5: 27Sep2016
No significant change. I don't run it nearly as often as I did previously (cat litter box went into a closet of its own to limit dust). The fan operates on one speed regardless of the speed selected. I'm toying with the idea of getting a higher-end model soon. We'll see.
Picture: After a month of on-and-off operation, this is how dirty the carbon filter got. Mind you, this room has never had filtration in nearly 8 years -- just like anything you clean, imagine not cleaning your shower for 8 years?
Works really well for removing allergens.
