Air Purifiers for Home Bedroom up to 1,035ft² with HEPA Filter, Carbon Filter, Washable Filter for Smoke, Pollen, Dander, with Air Quality Monitor, Auto Mode, 3yr Warranty, Airmega 150 White

We recently moved to the city into a tiny apartment with a large dog that sheds heavily. I don't usually have allergies but noticed that I started sneezing a ton more in this new living situation. I did a bit of research on air purifiers and settled on this one primarily because of the price and the way it looks. I wanted something that was visually unobtrusive. I have been very happy with how this purifier has worked out for us. We've definitely notices an improvement in the air quality in our apartment. It has eliminated all of the sneezing I was experiencing. It is quiet in it's low and medium settings, and sounds like a fan on the highest setting. I leave it on auto mode and it really only kicks into high gear when the dog lays on her bed (right next to the purifier) or when we're cooking. It seems to be very sensitive to increased air pollution and adjusts the speed responsively. The pre-filter works really well. I'm a bit appalled by how gross it gets, but it's nice to see that it is, indeed, filtering small particles out of the air. I give it a quick wipe with a wet cloth once a week, very easy and convenient to clean. Worth the cost, very happy with this purchase.

Pros: - easy clean dust filter. simple to vacuum and rinse - Cool design and shape. Less all around noise compared to the smaller round ones . Flat shape fits next to stuff better Cons: wish it had wheels or rounded bottom. Would make it easier to slide around on carpet or hard floors. touch sensor doesn't work well with wet fingers expensive filter replacements

I previously had a nice-looking, "smart" Mila air purifier. It was fine as an air purifier, but it was very expensive, and the "smart" features kept disconnecting. So, when it finally stopped working, I decided to replace it with an air purifier that's relatively simple. However, I wanted something that still matched the aesthetic of my apartment. This Coway 150 seemed to fit! Love the look of it, and it does a pretty job purifying, as well. Cooking? The purifier starts running. Open the hallway door? The purifier starts running. I feel better about the air quality in my apartment while also being happy about how it looks.

TL;DR Pros: -Quiet -Relatively small -Looks good (personal opinion) -Relatively inexpensive Cons: -Needs better documentation -Missing second charcoal foam filter -Missing any sort of convenient handle -Not suitable for large rooms/spaces Detailed Review: I have one of the AirMega AP-1512 (now replaced by the almost identical 200M). My choice in selecting and procuring that model was down to all the great reviews that compared the performance, power consumption, cost to buy, and cost to own of several of the top performing and popular brands on the market. There were others that outperformed the Coway, but not enough to be significant, and none were as cheap to procure and own (the running costs of the Coway were hands down less than any other brand). Having a great experience with the AP-1512, I decided to try the new 150 model to use in a smaller room (my 10’ x 10’ office), and because being confined to my house for the past year has more dust being created were I sit and work all day. My first impressions were good. The 150 seems to be well built and has familiar features and layout to the older unit I have been using for years. One thing I notice immediately when I was unboxing the unit was that it only comes with a single charcoal foam filter, which is supposed to be changed out after 6 months, but the HEPA filter is at 1 year. This means I either have to use the foam filter for a full year or replace the HEPA filter early. I wish it would have come with 2 of the foam filters as you would get in a filter replacement pack. Outside of missing one foam filter to make it through a year (and you can only by the replacement filters as a set and not individual components), the unit is also missing any sort of convenient handle to pick up and move it (the AP-1512 has a handle on it). After getting all the wrapping and tape off, the filters installed, and plugged into power, it fired right up and started working in Auto mode. The first thing I noticed is how quiet it is, but also how gentle the air flow is (meaning it isn’t flowing much air at low speed). There was a mild smell to it from the glue on the filters, but after a few hours (maybe a day), this all cleared up (I’ve heard some with major complaints of glue/chemical smells on the AP-1512 replacement filters, so I wasn’t overly surprised). I noticed that after running for an hour or so, the color changing light for auto mode was off and the unit said it was in Mode 1 instead of Auto. I thought something was up, so I cycled through the different Modes (fan speeds) and back to Auto. It stayed there for a while and went back to Mode 1. I thought maybe I had a bad unit, so I read the manual to make sure I understood its operation. That’s when I found out that the manual sucks and does not have near enough information about how this unit works and I now see why there are certain questions about this unit on the Amazon product page (like which was the filters are as the label FRONT on the HEPA filter actually points to the inside of the unit, which would technically be towards the back wouldn’t it?). It turns out that the Auto mode sometimes kicks out and into a more power saving mode, and when it does this, it erroneously shows as Mode 1 (and note that when it does this, it is flowing less air and even quieter than when showing as Auto Mode with a Blue status / air quality light). When the air quality is sensed to be bad enough, it pops out of the Mode 1 and into Auto Mode, so I guess this is all normal. As many have mentioned, this unit is pretty darn quiet, except when going into high gear. At the mid-level (Mode 2 or Green air quality light), it is a bit louder, but not too bad. Mode 3 (Yellow air quality light) is much louder, but about what I expected as the AP-1512 isn’t exactly quiet when it thinks it needs to evacuate the room of all dirty air right this instant. After living with one of the Coway 150 for a couple of weeks, I ordered a second unit to go in another room (13’ x 13’ bedroom) and next to a cat litter box (to help with dust control and general air quality in the room). I noticed that it’s Auto Mode and lights worked the same as the first unit (confirming that I didn’t just get a bad unit). I also noticed that the fan motor was a bit noisier, so I was wondering about quality control of the parts used to make these units. After a few weeks though, the fan motor quieted down and is about as silent as the first unit I procured. These two units are working well and I would certainly think of getting another if needed or recommending one for another person; however, I would not recommend the 150 for anything other than a small room (like an office or regular bedroom). If you have a larger bedroom, living room, etc., then I would look at the 200M, 300 or 400 to cover the larger space as the 150 just won’t cut it.

Very good product. My son's allergies are gone. It's amazing how such a small product can bring such improvements in our lives. Very clean air and healthy living.

Given the retail price and the smaller form factor, I figured I'd give the Coway Airmega 150 a shot. I use the Mighty (AP-1512HH) as my purifier for my bedroom, but the high power and ability to move air seemed overkill given the small 12x12 space. After receiving the Airmega 150, I was pleasantly surprised at the quality and attention to detail. The aesthetic and design is perfect, however the footprint was not as small as I had hoped, even though I read the measurements. Essentially its about the same as the Mighty, but 3" less in depth. That means it will sit more flush to a wall, but likely not enough to save space. Regardless, I was happy to have something with less airflow, better suited for my bedroom. This is where I was a bit underwhelmed. When on setting 1, the fan is whisper quiet, but at 2 and 3 you can definitely hear the fan motor. While its still within the dB threshold as stated by Coway and definitely quiet, its way more noticeable than the Mighty which just sounds like air moving. This is likely due to a smaller motor working harder to power the fan, which leads to a louder overall sound. The deal breaker for me was how the purifier was designed. The front panel of the purifier separates to expose the charcoal and HEPA filter, which securely fit into place, HOWEVER, there is a seam on the edge of the purifier that is in the direct path of the fan, so air can get sucked into the sides of the purifier, escaping the filtration features altogether (see picture). While I'm sure a majority of the air will go through the face of the fan, I feel like this is a big oversight and is not ideal that non-filtered air is able to pull through the purifier. I think the design intent is that the edges of the HEPA are compressed on the front panel, however the seal is not good because a thin piece of paper held to the side of the unit sucks to the surface, indicating the fan is definitely pulling in air on the sides and directly into the unit. While I don't think this is a fatal flaw, it was enough to not make me replace the Mighty, and give my mom the Airmega 150 for her room. PROS: -Smaller footprint, but not tiny -Touch controls are perfect, light indicator is great -Ability to turn off light indicator -Quiet, but some discernable motor noise CONS: -No available filters right now (I'm sure this will change) -Sides of the purifier allow air in, unfiltered. This was overlooked and is a big flaw to me -Airflow is not as good as the mighty, but good enough for a bedroom

I love it!!! It's quite when monitoring the air, gets louder with each higher setting, which is normal. There is nothing really to set up, just install filter and plug it in. I like to see how colors are changing of the air quality as it's monitoring. It looks very nice as well!

I've had this unit for a couple weeks now and I'm extremely pleased. Considering purchasing another one! Have owned several air cleaners over the years, returned a few immediately due to noise and unpleasant smells, and this one is the best. Form is A+, looks great - function is A+, works great. This unit is being used in a multi-use living/sleeping area with high ceilings in an urban environment, work from home, cooking, dust, pet dander, etc. This Coway is sensitive to air changes happening during cooking times, ruffling bed clothes when making the bed each day, an open window allowing additional dust, traffic, outdoor cooking smells when they occur - super! Unit controls are intuitive and filters are easy to change and/or clean. Also quiet on 1st setting around 20db for night time and sleeping - incredible! I use the 2nd setting for the workday, also quiet. The 3rd setting is probably in the 50-55 db area, perfect for when you leave the house, or you may use the Auto setting which adjusts accurately to changes in air condition. 4 air quality colors are nice too - BLUE, GREEN, YELLOW, RED - I've had them all! Lastly, there's no timer and that's okay with me - it's on 24-7! Excellent and 5 stars!
