We live in a wood house. Zero carpet. 7 humans, 3 dogs, 3 cats. There are no words to describe the amount of hair and dust that I battle on a daily basis. I pretty much gave up. Started researching air purifiers..... Lots to learn about them. Anyway, settled on 1 and got it. It's been 4 days and we are simply amazed. Baby hasn't had a runny nose in 2 days and he has had a runny nose since he was born. He has eczema, which is pretty much controlled by the diapers and wipes we use, but he still has a small rash that never completely goes away. It's gone. My nose hasn't been an issue in 2 days and None of us have been coughing. We all coughed, all the time.

The dust.

It's gone too. Dusting twice a day still didn't help before. It's simply not there. In addition to a wood house, one end of the house is all glass....so even after I dusted there was always "glitter in the air" as my toddler called it. It's gone as well.

It might be all in my head, but I swear my mood and energy are better too. (Could be because the house appears clean, or it could be in my head...either way...I consider this a win!) If you have any issues with this kind of stuff, look into getting one. I wish I would have long before this! I posted this on social media and 5 of my friends have ordered it now too. We are getting a second one for the lower level of the house. We have an open floor plan and it covers a very large area. Homes with out open floor plans may want a second to rotate in sleeping areas.

***To date 6 friends/family ordered and love theirs too! Great Buy!!

There are 2 things going on here. We just evicted a disgusting tenant to get our house back. There was something in the air that was making me sneeze, runny nose, can't sleep etc. From the first night all of that stopped. And the fan on turbo is the perfect amount of white noise to fall asleep to. The remote is nice to. The 2 is us also smoke about a pack a day each and this thing tackles at least half of the smell. It's light so I can easily move it to whatever room we're in. I want to buy one or two more but the price went up from the $130 I got this one for. When they go back down I certainly will buy more so I don't have to move it. This seems like a great heavy duty air cleaner.

At $135.00 you cannot go wrong with this air purifier. I've owned Winix 9500 and 9000 models going back many years, and the build quality of this 5500-2 unit is the same high standard (made in Korea, and obviously with concern for high-quality). However this unit is quieter than the most recent Winix 9500 units that I purchased from Amazon, which both had an annoying oscillating sound to the motor. The motor of this 5500"“2 unit is uniformly quiet with no such issue. So yes, the 5500"“2 unit is quieter than the 9500. Also, the cost of replacement filters is less, although of course the replacement filters are somewhat different than model the 21 filter which goes in model #9500, so not exactly a direct comparison, but still a cost savings. Because of its quieter operation, and lower cost of replacement filters, I recommend this unit over the Winix 9500.

Now when you start comparing this unit to other brands, I don't think that there are any contenders which match the quality and features at this price point.

Opened and setup unit, immediately noticed a strong oily smell from the exhaust port into the room air. Returned it the next day. First unit received lasted five days before the oily smell developed. Returned both units. Not a fan of this brand. Purchased two Oreck units. Much better IMO.

I've been looking for a new air purifier for almost a year now, doing research here and there trying to find a unit that meets all the requirments I'm looking for. I need a unit that's for a larger room, has an auto feature, has good priced replacement filters, and looks good to match my home decor. A recent 80,000 acre fire hastened my research due to the thick blanket of smoke that blanket the area (and still is) every morning. With all things considered, the Winix 5500-2 met all my requiements.

The unit arrived promptly and unpackaging was an ease. I literally had it set up ans running in about 5 minutes. The body is a hard, matte black plastic that feels sturdy and durable. The front panel is easy to remove, and secures to the unit via a clever magnetic clasp that is secure, yet simple to remove to access your prefilter for bi weekly cleaning and hepa/carbon filter replacement. There are 3 filters in total, and they fit snugly inside the filter chamber, amd ate secured in with the prefilter that snaps firmly into place.
The control panel at the top is intuituve and user friendly. The buttons are clearly marked and visual ques explain what each button does taking out any guesswork as to what they do. A stylish indicator light bar runs along the bottom of the control panel indicating the level of air cleanliness with a 3 color scheme...green for clean, orange for okay, and red for bad. You can manually run the machine on 4 fan settings, or choose auto mode and let the machine choose the settings based on the data colected from the sensor. This means hands off operation. There's a night mode that will set the fan to its lowest setting to cut down on noise, and also dim all lights on the panel. This night mode will set automatically if you have the auto mode set on the unit, a light sensor will detect (or not detect) any light in the room and go into night mode. A filter change indicator light also is on the control panel. According to what i've researched, the hepa filter should last approx 1 year. It also comes with a remote control with a battery preinstalled. I dont plan on using it, but if that's your thing, it's there.
This is the quietest air purifier I've ever owned. On level 1, it's almost undetectable, and even on level 4 turbo mode, it's no louder than a standing floor fan on high. This was a very pleasant surprise.
It cleans the air well. I'm currently using it in my 350 sq ft bedroom. I don't have the equipment to test it, but per their website I should be getting at least 4 air changes per hour which is the amount of air exchanges you need for allergies and serious air purification. I've had no smoke smell AT ALL in the bedroom when I run this with the door shut to the rest of the home and it was initially startling to walk from the bedroom into the rest of the home after the first night of using it.
This unit has more than exceeded my expecations ans meets all the things I was looking for in an air purifier. I plan on purchasing 2 more of these when money permits for my combined kitchen/dining/living room area that totals 700 sq ft. I can place these at opposite sides of the area and get more than ample coverage. I would highly reccomend this unit. For the price and the feature list, this just can't be beat. The cost is low, the replacement filters don't cost an arm and a leg, it covers a large area, and you get a lot of features.
