Very good air purifier

Dusting is my least favorite household chore.  I have noticed much less dust in my house since using this product so this is worth the money.  The only problem I have with it is that it is a little noisy on the lowest speed.  Speed 2 is the best with the "white noise" it makes being easy to get used to.

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 don't 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.

We got this air cleaner to replace a much simpler air purifier and can definitely notice the difference. Most important is the automatic functionality - you can set this thing to run and it will automatically adjust based on what is in the air. When there is any kind of odor it will kick into a slightly higher filtration mode and neutralize it fairly quickly. Its default mode is almost silent, which is nice during the day to forget that it is there.

However, we also use it as a white noise machine at night so it's nice to be able to override the automatic function and turn it up to middle power at night so that it can serve a dual purpose. The screen is easy to read and to understand and the remote control (which comes with an adhesive holder) makes it easy to turn on and off (or up and down) from a distance (for instance, you don't have to get out of bed to change the level it runs at).

It is a fairly big unit so you need a big space to make full use of it. Our bedroom is about 450 square feet so it works perfectly for us but might be overkill in a smaller room. The set-up is straightforward - there are some plastic pieces to remove and then you're ready to go. We haven't had to replace the filter yet but that seems fairly straightforward too as it all comes out as one piece.

I have a serious health condition that requires me to have several types of air filters going in my home at all times. This Airmega stays in smart mode and as such, it monitors the air continuously to automatically ramp up the circulation when it detects contamination.  A regular cleaning of the washable prefilters keeps it running in tip-top shape and it compliments my other filters very well as they do slightly other things.  Depending on your particular needs I do recommend this product.  I find great satisfaction every time I notice the light change color and the fan speed up to clear whatever particulates it happens to be saving me from this time.  If you need an expensive air purifier you probably have particular needs so definitely do your homework and make sure this one will suit you specifically... but for me, in conjunction with the other filters I have, it works very well.

I bought this about a year ago.  There were a number of forest fires in my area and I was having problems breathing.  I hoped that this would help clean up the air in my house.  I have let it run continuously for a year now.  It is reliable and quiet.  I have to clean it on occasion, more often when the outside air is dirty.  I clean it with a Swiffer and this works really well.  When it is really dirty I have to wash the blades with a damp rag.  Of course you have to let them dry like putting water into any electronic device.  It does not move a lot of air and it is not a fan, it is a great air cleaner.  It works very well and I couldn't be happier with it.

This air purifier seems more efficient than others we've tried.  The air produced is "sweeter" smelling compared to others, not as stringent.  It's a sturdy, well-made box.  The only thing missing is maybe a handle on top for ease of moving from room to room.  The energy use is very low and economical.  Great overall generator, very happy with it!

Great little air cleaner. Received it in 2 days and put it right to work.  Nothing much to do to set it up except to plug it in, flip a switch at the bottom front to decide if you want the ionizer on or off and then set it up in the room 3 ft from pretty much anything.  Super quiet and can tell the difference in the air quality almost immediately.  The blue light makes a nice night light and is a pleasing color, in my opinion.  Definitely would recommend buying this air purifier.

This unit came ready to set up. After removing it from the box,I removed the back grill and took the two filters out,one on top of the other.i removed the plastic wrapping and simply reinstalled them. There is a scent compartment,where the cartridge is inserted. I do not use scents so I did not follow through with that,preferring neutral. It has a knob however to adjust the strength of the scent.
The air cleaning level is congruent with the fan,which operates three different speeds,almost perfectly quiet on the lowest notch. However it is audible and rather strong circulation on the upper two levels. I noticed almost immediate changes in air quality ,after an hour the bedroom seemed much fresher. Air changes 5 times per hour in a 170 square foot room.
I am quite happy with this unit,and the base cost for a medium/large room format. Really works to control dust/dander levels.
Filters are replaceable.

Very good machine and is worth the money for good clean air!  Pros: very quiet on low and medium speeds. Filters are easy to access. I also bought the Air Module for it so it does work similar to the Pro XL model. Cons: It is a bit noisy on high speed. This item is in a very large box and requires 2 people (or a dolly) to carry the item.

For future improvements suggestions: 1. Add the ability to use a remote control with it 2. offer a heat function so you can use the purifier in the winter to heat the room it is in while cleaning the air. 3. offer a dust cover for when storing the unit in the off season.

Overall i do recommend this product!

I did a ton of research before buying an air purifier and I'm glad I went with this one.  It is quiet as a mouse, unless it gets a whiff of something bad.  If you hear the motor amp up, get ready, because you're about to be nasally assaulted by something stinky (dog farts!). We have three indoor dogs and a cat and this purifier does a fantastic job of grabbing dander and dust out of the air.  I'm really pleased with it.

Well, I've had this AeraMax air purifier for a year and a half now, running almost constantly and it's been great. Runs well, keeps the air in my bedroom clean & fresh. I get stuffed up pretty frequently, not really allergies, but just general stuffiness and this air purifier seems to help keep me clearer. (I've turned it off some nights just to check how much difference there is.) It's form keeps it from taking up much space and it's perfect for a small apartment or a large room. Highly recommended.

This is a very good air cleaner. We've had it for about 5 months, and it really does an adequate job. Very quiet on both settings.

seems to clean air very well - YOU OUGHT TO SEE THE FILTER - need to clean at least once a week

I really love this air purifier. The thing where this air purifier shines is how quite it is. Not to mention that works like a charm. Definitively recommend this air purifier to anyone. Great investment.

Product came in a very timely matter. This Air Purifier is excellent in purifying the air, even on the Med & High Settings its not that loud on the high Fan setting. You'll evidently adjust to the noise as you sleep at night, and has the special Ozone features and other features if you live with pets and are trying to filter out very difficult  bad odors and smells in the air. Very good in removing various gases and odors from the air as long as you clean the filter periodically.

I really like this air purifier. It's very quiet, stylish by design,has a soft blue light. I needed a white noise machine/air purifier for my toddler's bedroom. There are no expensive filters to change so that's a big plus. It is easy to clean. The only cons for me would be the light being a little too bright for my liking and the air purifier being too quiet. I was hoping it would be a tad bit louder to really provide a white noise effect. It definitely does the job well, though.

I have been extremely happy with the Fellows air purifier. It is very quiet and has done an excellent job of removing cigarette smoke from my home.
