There was a problem filtering reviews right now. Please try again later.
I have now purchased a total of four of these Coway air purifiers to date. I have three installed in different rooms in my house, and I have one in my office at work.
I am completely satisfied with their operation, which is completely unnoticeable and without any discernible noise except for those very infrequent occasions when the unit does detect something in the air which causes it to increase the fan speed for a short period of time. Even then, the operation is very quiet.
The units at my home run continuously 24 hrs/day on the Auto setting. The one in my office at work is turned on only when I'm in the office.
I've replaced filters quite a few times, and it is an easy exchange. The unit also should be cleaned with a vacuum and damp cloth periodically, and there is an air quality sensor on the side of the unit which should be cleaned as well. Filter removal and replacement is easily done.
The Whirlpool unit that I mention in my original review below has now been thrown out, having given me quite a few years of good service, however it was never as quiet as the Coway.
My original review follows, without edit (other than correcting my mis-spelling of the product name, which is Coway and not Conway as I wrote originally).
==============
I purchased two of these Coway air purifiers after doing a fair amount of internet research, reading reviews and so forth.
Most significantly (to me), the Wirecutter website has recommended this air purifier since 2015, and in their most recent updated comparison review they continue to give it their top recommendation. In their review, they explain how they have tested air purifiers for the past seven years, a total of 42 different air purifiers evaluated over that time period, and this Coway is their pick.
Unpacking and setting these up was simple and straightforward. Note that it is necessary to remove the front cover of the unit and remove the pre-filter, carbon filter and HEPA filter, remove each from the plastic packaging before reinstalling and beginning to use this air purifier. I make this point because one of the other reviewers apparently didn't think to read the instructions before putting their unit into operation, discovering later that the filters inside the unit were still wrapped in plastic! Read the instructions!!
When operating, the unit is practically silent - very surprising. I have them both on the 'Auto' setting, which results in the fan operating at the first (lowest) speed unless the sensor detects more dirt in the air, requiring a higher speed. When the fan speed is manually increased to the higher settings, it can be heard but is not objectionable. Both units have been operating for several days now, and 99% of the time they operate at the lowest setting. We have one unit in the bedroom and the only way to tell that it is operating is by noting the indicating lights, or holding your hand over the top of the filter where you can detect the airflow coming out.
It is interesting to observe how the units do (very) occasionally increase speed, and when that happens the operating light will change from blue to red, and the fan noise will become very slightly louder, just enough to hear in a quiet room.
By comparison, I have a Whirlpool Whispure Air Purifier, HEPA Air Cleaner, AP51030K purchased in 2012 which we are still using. It has similar capabilities to this Coway unit, but is much louder even on the lowest speed setting. (to be clear, we have not used it continuously since 2012, but I do not recall it ever being as quiet as this Coway.)
Since we are just beginning to use this Coway product, I don't have any long term experience to include here. I will return to this review and update it if I have significant comments to add.
Aesthetics aside, it is also built well... and perfectly sized. I attached photos to show that it's not too tall, nor is it too deep. It is a bit shorter than my nightstand, which is of an average height. It's a bit on the wide-side, but you can position it however you see fit. It does need about a foot on the right side to allow for proper air flow, and probably a good idea to keep the front end free & clear since the "circle" is from where it pulls in air... but I found this guy could be positioned in many places throughout my home without being an eyesore. I have it in my bedroom currently, but I plan to buy one for my family room as well, and maybe the basement also. It really does work. My bedroom is often very stuffy, especially in the winter when we have the heat temperature set to 73 degrees -- I like it warm & toasty, but my nasal passages feel otherwise. I do suffer from pollen allergies, as well as mild allergies to dust mites, grass, ragweed, mold spores, and pet dander (although I still have 2 shed-heavy fur-babies.) But my allergies are never bad enough to warrant any real attention, I just suffer through it since they're pretty mild. HOWEVER, I keep saying mild when in all reality, I didn't know the difference between no allergy and mild allergy until sleeping one night with this purifier running. Man what a difference. My nose was not all dry and cracked up feeling on the inside. It also was not runny or scratchy, which is how it often feels after running my humidifier all night (which I run to keep my nose from feeling so dry!) This machine does not mask the issue, or dampen it, or freeze/cold draft it away.... it CLEANS THE AIR. I know, I know... it's hard to imagine, but boy is it easy to feel. I slept for the last 2 nights like a newborn baby. Granted, I've only had it for 2 days but the difference from walking into my bedroom vs the other rooms of my home, cannot be ignored. My home isn't particularly old, or stuffy, or dirty, or dusty. Yes we have pets, but I am a Dyson maniac and we have a brand new HEPA HVAC filtration system; we have our ducts cleaned regularly; and, there are no smokers or other reasons for contaminated air (at least that I can find.) However, when plugging this thing in... it ran a blue and then purple light for a bit on auto, but then changed to RED (which freaked me out a bit as it sounds rather aggressive). And it ran that way for about 10 minutes. I left it to its job, and when I returned a little while later, it was back to a blue light and I could barely hear it running anymore... but the air did in fact feel lighter, crisper, and easier to breathe. It felt much like the very first time I walked onto my hotel balcony in Vancouver, Canada and took in a giant breath. It just felt... clean.
Air quality is a legitimate thing, and having poor air to breathe makes life a less tolerable for people with allergies or lung issues. Again, not something I suffer from necessarily, but I appreciate the cleaner air this provides nonetheless. So I cannot imagine how much better breathing could be for someone that does have serious allergies, asthma, or other breathing troubles. I would say this gem is a no brainer, if you do. But even if you don't, you'll still notice the difference after plugging this guy in and letting it run for about the first hour.
I do think the auto feature could become a bit of a power monger as I have never witnessed it turn off after being on auto as if to say "okay, I'm done. All clean." So I do set the timer feature when I'm not going to be upstairs and I shut it off when I'm leaving the house for awhile. Another thing to note is that there are studies about potential harmful effects to lungs when using the UV and ion cleaning features. It is recommended that you only use these settings when not in the house as breathing in UV treated air is said to be harmful as a result of O3 air, similar to breathing in air high in ozone levels. So I only set my purifier with these features when not in the room.
I can't yet speak to durability or filter tolerance, but they are priced reasonably enough that changing once or twice a year would be totally acceptable. I will update if I find that longevity or level of purifying impact worsens, or if cleaning/upkeep isn't as great with this machine moving forward, but for now... I am a Coway air purifier believer.
** UPDATE - after 7 months of constant use, I will say that my initial reactions were still pretty accurate in that this purifier does do what it claims to do. I notice that it is reactive to smells, smoke and other air-purity issues when they are occurring, even when I am simply cooking sausage or something extra smokey or fragrant in the kitchen -- while I have this unit upstairs in my bedroom, which is a considerable distance from the kitchen (bedroom in front of the house on 2nd floor, kitchen in the back of the house on the 1st floor.) So I know that it indeed works because I can hear it begin to run rapidly when I accidentally burn something or even when making bacon or something that has a smell or odor. I also know that it is filtering dust and pet hair, because both of my Coway purifiers (I have one upstairs and the tower unit downstairs) needed HEPA filter replacements at 6 months. The manufacturers suggestion is 6 months for the carbon odor filter, and 1 year for the thick, HEPA filter.. but my HEPA filter was so dirty at 6 months that the "change filter" light came on for the tower unit, so I figured I would change this 1512HH unit at the same time, and it definitely needed it. The filters were both clogged with so much dirt, dust and pet hair.. I couldn't believe this stuff was floating around my house for it to grab. In fact, even strands of my hair were in the filter! And my hair is pretty long, well below shoulder-length. I figure it must have sucked it in from the floor. Pretty cool purifier... I still give it 5 stars and 2 thumbs up after 7 months of use.

Aesthetics aside, it is also built well... and perfectly sized. I attached photos to show that it's not too tall, nor is it too deep. It is a bit shorter than my nightstand, which is of an average height. It's a bit on the wide-side, but you can position it however you see fit. It does need about a foot on the right side to allow for proper air flow, and probably a good idea to keep the front end free & clear since the "circle" is from where it pulls in air... but I found this guy could be positioned in many places throughout my home without being an eyesore. I have it in my bedroom currently, but I plan to buy one for my family room as well, and maybe the basement also. It really does work. My bedroom is often very stuffy, especially in the winter when we have the heat temperature set to 73 degrees -- I like it warm & toasty, but my nasal passages feel otherwise. I do suffer from pollen allergies, as well as mild allergies to dust mites, grass, ragweed, mold spores, and pet dander (although I still have 2 shed-heavy fur-babies.) But my allergies are never bad enough to warrant any real attention, I just suffer through it since they're pretty mild. HOWEVER, I keep saying mild when in all reality, I didn't know the difference between no allergy and mild allergy until sleeping one night with this purifier running. Man what a difference. My nose was not all dry and cracked up feeling on the inside. It also was not runny or scratchy, which is how it often feels after running my humidifier all night (which I run to keep my nose from feeling so dry!) This machine does not mask the issue, or dampen it, or freeze/cold draft it away.... it CLEANS THE AIR. I know, I know... it's hard to imagine, but boy is it easy to feel. I slept for the last 2 nights like a newborn baby. Granted, I've only had it for 2 days but the difference from walking into my bedroom vs the other rooms of my home, cannot be ignored. My home isn't particularly old, or stuffy, or dirty, or dusty. Yes we have pets, but I am a Dyson maniac and we have a brand new HEPA HVAC filtration system; we have our ducts cleaned regularly; and, there are no smokers or other reasons for contaminated air (at least that I can find.) However, when plugging this thing in... it ran a blue and then purple light for a bit on auto, but then changed to RED (which freaked me out a bit as it sounds rather aggressive). And it ran that way for about 10 minutes. I left it to its job, and when I returned a little while later, it was back to a blue light and I could barely hear it running anymore... but the air did in fact feel lighter, crisper, and easier to breathe. It felt much like the very first time I walked onto my hotel balcony in Vancouver, Canada and took in a giant breath. It just felt... clean.
Air quality is a legitimate thing, and having poor air to breathe makes life a less tolerable for people with allergies or lung issues. Again, not something I suffer from necessarily, but I appreciate the cleaner air this provides nonetheless. So I cannot imagine how much better breathing could be for someone that does have serious allergies, asthma, or other breathing troubles. I would say this gem is a no brainer, if you do. But even if you don't, you'll still notice the difference after plugging this guy in and letting it run for about the first hour.
I do think the auto feature could become a bit of a power monger as I have never witnessed it turn off after being on auto as if to say "okay, I'm done. All clean." So I do set the timer feature when I'm not going to be upstairs and I shut it off when I'm leaving the house for awhile. Another thing to note is that there are studies about potential harmful effects to lungs when using the UV and ion cleaning features. It is recommended that you only use these settings when not in the house as breathing in UV treated air is said to be harmful as a result of O3 air, similar to breathing in air high in ozone levels. So I only set my purifier with these features when not in the room.
I can't yet speak to durability or filter tolerance, but they are priced reasonably enough that changing once or twice a year would be totally acceptable. I will update if I find that longevity or level of purifying impact worsens, or if cleaning/upkeep isn't as great with this machine moving forward, but for now... I am a Coway air purifier believer.
** UPDATE - after 7 months of constant use, I will say that my initial reactions were still pretty accurate in that this purifier does do what it claims to do. I notice that it is reactive to smells, smoke and other air-purity issues when they are occurring, even when I am simply cooking sausage or something extra smokey or fragrant in the kitchen -- while I have this unit upstairs in my bedroom, which is a considerable distance from the kitchen (bedroom in front of the house on 2nd floor, kitchen in the back of the house on the 1st floor.) So I know that it indeed works because I can hear it begin to run rapidly when I accidentally burn something or even when making bacon or something that has a smell or odor. I also know that it is filtering dust and pet hair, because both of my Coway purifiers (I have one upstairs and the tower unit downstairs) needed HEPA filter replacements at 6 months. The manufacturers suggestion is 6 months for the carbon odor filter, and 1 year for the thick, HEPA filter.. but my HEPA filter was so dirty at 6 months that the "change filter" light came on for the tower unit, so I figured I would change this 1512HH unit at the same time, and it definitely needed it.

Although footprint is small, it is a large square that sits about a foot away from the wall. In a small space this may not be so great but I love it.

A los que están investigando la compra de un purificador de aire les recomiendo que analicen muy bien su situación particular. Este purificador me ha sido muy útil ya que elimina polvos, olores y la gran mayoría de contaminantes, también por lo que investigué elimina solo parte de los gases emitidos por los automóviles en zonas de tráfico pero cuidado, no los elimina del todo, si tu vives en una zona de mucho tráfico vehicular y necesitas eliminar los gases producidos por el tráfico necesitas otro tipo de purificador. En mi caso particular ha resultado excelente compra y si lo recomiendo, estoy por comprar el segundo para la recámara de mis hijos.

We are experiencing extremely high levels of smoke for weeks of the summer due to Forrest fires. This purifier completely removes any hint of smoke from my entire home. My house is 1500 sq/ft, larger than what this is rated for, but it works great. I usually use it on power level 2 and it is a very reasonable volume. Level 3 is loud, but moves a lot of air, so it’s great for when your trying to remove a problem.
This has dramatically reduced the build up of dust on surfaces in our home, and reduced my headaches during the Forrest fire season.
I’ve told family member about it and they went out and bought one too. I highly recommend it.
