**1+ YEAR PRODUCT LONGEVITY UPDATE** Been running on medium setting, sandwiched in my doorway, creative positive air pressure (harder on any fan motor) and getting the door slammed into it by my daughter and myself at least once a day for over 1 year strqight now, around the clock, no breaks for this unit EVER since the day it arrived other than a couple of brown-outs which I thought would have burned something in the circuitry up forsure and purposely left it plugged in the entire time just to test how good the protection was. 48+ hours straight of random AC40v-AC160v coming from the outlets and you could hear the fan spinning slower/faster when it would actually function. Anything less than about 80v it would beep and try to resart itself, and took the random 40v jump to 160+volt spikes, in this continuous cycle while.the power was out the entire time - like an absolute CHAMP. This is my last and final update on this product, I cannot recommend the eureka filters for it at all, they do not filter the very fine dust particles. They are strictly made for this devices purpose which is to be a VERY WELL DESIGNED/BUILT HIGH VOLUME AIRFLOW TOWER FAN imo, with some filtration which is most deffinatepy better than none,, and absolutely works for the main particles people don't want in their homes. Easy fix is to purchase a 3rd party 3 pack of replacement filters for the same cost as 1 of the eureka brand filters like I did about 2 momths in, and they filter everything, and consequently cut the airflow of the fan down about 25-40% and I had yo start running it on medium speed instead of the usual low/silent setting which flowed about the same as the new configuration. That's just how "airy" the eureka filters are lol. I figured the new "real" hepa filter replacement would put too much of a strain on the unit and was 3xpecting it to last maybe 6 months considering the price I paid at the tike for this unit. This unit is the absolute best value for anybody looking for a secondary air cleaner that's main function is to move/circulate as much as as a standard filterless tower fan while being virtually silent on the medium setting, which moves MORE air than any other tower air cleaner style that I've tested... on theier highest and loudest settings .. unit is all around a well-built GREAT investment that actually performs, and is built to LAST. I am absolutely amazed at the fact that the fan motor in this unit hasn't suffered any type of performance loss or started to make any types of noises after over a full year of abuse and running 24/7-365. THIS AIR CLEANER IS/PROBABLY WILL FOREVER BE - THE ABSOLUTE BEST AMAZON OFF-BRAND GAMBLE PURCHASE THAT I HAVE EVER MADE. if you don't own one of these, BUY ONE and stop second guessing yourself. Nothing on the market has this exact configuration of noise:airflow:filtration levels, and not a single tower I tested up to $249.99 moved as much airflow as this one is capable of with the included filters. This product is my favorite amazon purchase of all-time and is an absolute must. Will be buying another soon just so that I know I have a brand new one in my closet for whenever this one has had enough abuse and decides to give up. I don't see that happening for at least another 2-3 years though, if EVER to be completely honest. THIS PRODUCT IS ABSOLUTE A+ QUALITY AND IS AN GRADE A CHINA-MADE BRAND RARE TREASURE GEM'S! Hope this helps some people ???????? *90 DAY PRODUCT LONGEVITY UPDATE* unit has been running on medium setting/UV on for 3 months straight 24/7 now and still no strange sounds or any changes to report whatsoever EXCEPT that the units air filter does NOT filter as good as a true heppa and thats why the airflow is so great I suppose. The front grill does have a coating of dust starting to build on in but for the most part, this thing is still better than most regular tower fans for the money, and the fact that the filter does obviously do something because I already need a new one, along with it having UV light for antibacterial are just huge pluses to this powerful "filtered tower fan" - describes the product much better IMO, still not mad about the purchase in the least bit. Purchased 4 other tower design air purifiers over the past month that all cost between $100-$200 including both germ guardian 22" models due to wanting the UVC function, and even the IFD honeycomb style ionizing permanent filter design from Honeywell. Every tower on the market seemingly has the same exact issue, the airflow comes out of the front vent but blows way off to the side, which means you have to turn the unit 90 degrees away from the direction you want it to glow towards (you have to place the units sideways instead of facing the room) or in the case of the electrostatic permanent filter design from Honeywell, it worked great as a oscillating tower fan (if you need the oscillating feature its best suited for that) but the actual purification just couldn't compare to an actual HEPA filter like this one is. I honestly didn't consider this unit at all until I exhausted all other options before ending the search and just buying a small tower fan instead to place in the doorway....and im so happy that I did. Not only did I get the unit for half of what all the others cost, but it actually has a hepa filter with foam around it for an airtight filter seal (my $200 winix unit dosen't even have a air tight filter seal) but it also has at least some form of UVC light...germ guardian was my first choice because they use the actual 5 watt UVC florescent style lamps, meanwhile this unit is an LED... Therefore I didn't expect much germ killing power from this unit, and expected a basic, cheap, low airflow, filtered tower fan at best.... BUT after reading the manual, come to find out it's actually a 2 watt LED bulb (quite powerful for it being LED) so I do feel alot more confident that this unit can kill bacteria just as well as the germ guardian units, if not even more efficiently. This unit is a little on the loud side, BUT thats only because it pushes ALOT more air than the other units, and actually sends it straight out of the front grill instead of out to the side due to proper engineering. For comparison, on the medium setting, this unit is moving more air than any of the other units I tried, on their highest setting which was either just as loud if not louder. If you want quiet, get a winix air purifier. If you want the tower design and need it for specific placement like me, and a tiny bit more fan noise is no issue, then SAVE YOUR MONEY. This is the only one to get.. I have this one with UVC in my doorway pushing in cool fresh air, and then my winix inside of the room with it ionizing plasmawave and much better filter technology, so running them together on low around the clock covers my 300sq foot room perfectly and fits my extremely specific needs perfectly. *I cannot comment on the durability of this product as of yet because I just received it yesterday, but as long as this review stays unedited, then the unit is still working like the day I recieved it.* Great product for the money. I'm honestly blown away that this CHEAP unit addressed almost every issue with the units I tried that cost 3x the money. Five stars all day long.
