    • Liked it enough I bought a 2nd one
Style: 400 Graphite
So far, overall impressive. Quiet, powerful and a noticeable difference in air quality. This unit is a box stand shape and needs to be placed with some common sense to function properly. Air is pulled through the sides (pre filter then main filter), and then expelled through the top grate. The pre filter can be cleaned with a simple removal and vacuum (2 sides). The main filter is thick and charcoal based. There is a sensor on the control panel for the pre-filter that changes its display and color as the pre filter becomes more dirty. Once the pre filter is cleaned, simply hold down the pre button with the sensor for 2-3 seconds and it resets. Very simple, not overbearing and well thought out design. The auto sensor tech is spot on and will kick in the appropriate level of fan control as needed. I liked it enough that I bought a 2nd one 2-weeks later (promo offer was key). This is an expensive unit, and at full price I’m not sure if I would have pulled the trigger so quickly, but so far I’m very pleased with the product, quality and performance. Highly recommended. ... show more

Review Image by Jim Teutsch
Update: It’s been over a year and I’ve replaced the filters once. The prefilters require regular cleaning, but the purifiers provide a status light to ensure you know when it is required. These continue to perform extremely well and I remain very happy with their effectiveness at removing dust and allergens from the air. Update: 5/16/2023: Both purifiers I bought continue to perform well. They are quiet and effective. I’m still using the original filters and still have a lot of life left in them, despite leaving them on the smart setting with a medium fan setting 24/7. Excellent purchase for someone dealing with asthma and/or allergies, pets and wanting a well-built air purifier for cleaner air and better breathing. Original review: I have asthma and allergies and have two dogs, and I wanted two well-designed, effective, stylish, large-capacity air purifiers for our great room and the master bedroom. These are very well constructed, easy to use, and effective. They have a set and forget feature that I really like. The pre-filters are easily cleaned with the vacuum brush attachment on your vacuum cleaner and the purifiers provide a cleaning indicator so you always know the status of the pre-filters. The main filters are very well made and are no doubt very effective and long lasting (I have not yet had to replace them and believe they’ll go a year before that is required.) I highly recommend these air purifiers to anyone wanting cleaner air, fewer dust bunnies, and less pet dander in the home. I set them, so they run when needed and shut off when the air is clean. I turn off the light before sleeping and they continue to perform as needed 24 hours a day. I’m very pleased with these and believe they contribute to better health. ... show more

    • Very Impressed with Build Quality
Style: 400 Graphite
One Year Update: After living with this product for one year I can tell you I appreciate its quality even more. Not a hitch in one year of heavy use. It just performs day in and day out. Washable screens require regular cleaning (every other week -- dirty farmhouse), but they are easy to clean! Every time I clean them I also vacuum the filter, and I think that is why I have a full one year of use out of our filters in a very dirty environment. I cannot emphasize enough how impressed I am with this filter's design and build quality. It just works. I can count on one hand the number of products that fit into that category. Summary: Superb build quality, support, and performance. Review after 1 month of use. I spent a lot of time researching larger home air purifiers including some commercial units whose filter replacement costs were almost as much as this complete unit. This product and company appeared to have some of the best quality and design, as well as superior support (go see their support website). I was not disappointed. Straight out of the box this filter had some of the most impressive packaging I have seen on a product. Build quality is top notch -- the fit and finish on everything is excellent. So is the design - from magnetic catches on the cover, robust filter build and fit, great status display visible anywhere in the room, to the easy to use control panel. This filter is a joy to use and maintain. And it works! We got it primarily for dust control in an old farmhouse. You will need to operate at higher fan speeds for dust removal (more noise), but the automatic mode is great at night for regular air cleaning and reduced noise. After reading tons of reviews on other products' poor build quality and terrible support, and then experiencing this product, I don't know why you would buy anything else. Final tip: don't bother with the Wi-Fi version, you will never need or use those features. ... show more

    • The Coway home purifier. Clean air for all!
Style: 400 Graphite
The Coway home air purifier is a great addition to a room without taking up much space. It is about the size of a small nightstand, making it easy to place in a living room, bedroom, or office without it becoming an eyesore. In a larger room, it blends in well and doesn’t draw attention. One of the best features is how easy it is to take apart for cleaning. The inner and outer filters can be accessed and cleaned without much hassle, which helps keep the unit running efficiently over time. The purifier operates quietly for the most part, making it suitable for areas where noise can be distracting, such as bedrooms or workspaces. It does a good job cleaning the air in a room up to around 500 square feet. The only downside is that the controls can be a little tricky to figure out at first. They are not as intuitive as they could be, but once you learn the settings, the unit is simple to operate. Pros: * Easy to disassemble and clean filters * Quiet operation * Compact and not obtrusive * Effectively cleans air in larger rooms Cons: * Controls can be a little difficult to use Overall, the Coway home air purifier is a solid, well-designed unit that performs its main job well while staying quiet and out of the way. ... show more

    • Noticeably cleaner air
Style: 400 Graphite
This air purifier has been working great for me so far, and I even purchased a second one for my parents! The air quality around here has been less than optimal the past couple of years, and so I decided to invest in air purifiers for my home, especially since I spend a lot of time around the house these days ever since my job has switched to working from home. I have an air quality monitor in the same room as this air purifier, and this purifier makes a notable difference when it is running, especially for particulates and pollen. There are a few things to keep in mind though: - I mostly keep it on the auto setting, which has worked well for me - If you are unfortunate enough to encounter consistently poor air quality for days at a time (for example, from forest fires), this thing will be running on it's HIGHEST setting to provide you with fresh air. This is not surprising to me, when there is literally no clean air anywhere to be found outside, and I feel lucky that I have this unit helping me breathe easily. - The noise levels are reasonable, and the sound this unit makes is not annoying in any way. The highest setting certainly makes some noise, but it is very smooth sounding and it's almost like a soothing background noise without any annoying buzzing sounds that some fans can make at high speed. Noise levels at low and medium speed are perfect, you may not even realize it is running unless the room is silent. - In smart mode, when it automatically switches from off to low to circulate air, the fan seems to make a burst of noise before quieting down that is noticeable -- almost like it starts at high and works its way down from there. This is slightly annoying, but I only notice it if the room is especially quiet. - Having said that, once the smart mode automatically switches to night mode, the unit is almost silent when starting up and running (that is, unless the sensor decides the air needs some purifying, then it might ramp up -- you could force a specific setting if you wanted to avoid the automatic switching too, but I am far too lazy for that). Sleeping in the same room that this unit is operating in is no problem. - The LED lights are too bright to use in a bedroom at night. There is a button to disable the lights, and while this helps, it doesn't disable all of the lights. I can see why they didn't want to disable all of the LEDs, since the ones that stay active are the ones that indicate that the system is running... but perhaps it could have dimmed them a bit when operating in this mode. I used a couple tiny led brightness reducing stickers to solve this problem. - The build quality of the unit itself seems to be top notch, at least as far as I can tell from the outside Overall, I am happy with this unit! ... show more

    • Take it from a skeptic: After 3.5 years, no regrets! This Coway air purifier is perfect!
Style: 400 Graphite
We purchased this unit in June 2022, nearly 3.5 years ago. That said, this review is coming from a place of experience with this air purifier. We had just adopted two cats that were born in the bushes outside our home, and I don't particularly care for cats (or more specifically, the smell of cats)! I was concerned about the price of this machine, not because it was crazy expensive compared to other machines that claim to be able to do what this purifier does, but because I didn't want to spend even half of what this thing cost just to keep the house from smelling like cats. On top of that, I didn't want to have to keep buying filters for it. I chose to bite the bullet and purchase this because I figured that if this device could keep the cat smell to a minimum, it would be worth every penny. The recommendation is every year or two, but they are so easy to clean that we were able to extend the filter life quite a bit! The outermost screen filters are quick and easy to get the dust off. It takes about one minute per filter (one on each side) to vacuum off. We clean these filters every 45-60 days. The innermost filters - the big ones with the charcoal - we clean every 12 months. Those take a little longer to clean, but no more than 5 minutes with a vacuum attachment. Everything on this device is easy to remove and replace. Now for the important part... Until just this very week, I have never - and I do mean NEVER - noticed a cat smell in our home. My in-laws have a cat, and they have commented several times over the years how amazing it is that our home never smells like cats - or any odors for that matter! My sister-in-law is allergic to cats but doesn't have any issues at our house. Fast forward to today, I have grown a bit fonder of the cats but still don't like cat smells! I came to Amazon today to purchase my very first set of replacement filters, if that tells you anything about the longevity of these filters! I decided to leave this review just in case anyone else is on the fence about this air purifier. It works. Perfectly. All day. Every day. Additionally, I no longer use expensive HEPA filters in our HVAC system because this purifier takes nearly everything out of the air that those would catch anyway. For anyone who's curious: We have a 1900SF home. I was able to find a great location for this fairly close to the middle of our home so that it purifies the entire house. I go weeks at a time without even realizing this thing is in the room - it just blends in and disappears! If it detects odors, it will speed up for a brief period of time, but almost always runs at the lowest speed - nearly silent. I'm certain that this would even work in larger homes than ours, because in our home it typically only runs at 25%. There are a number of controls so you can adjust the speed, setting, schedule, etc., but we never use them. We just set it and forget it. The power this unit can produce (and the amount of air it can move) is incredible. This purifier brings air in from the sides of the unit and exhausts it out from the top, creating perfect circulation. As an added (undocumented, unsupported) function, anything you place near the top of this unit (potpourri, air diffusers, essential oils, etc.) is quickly dispersed throughout the home. ... show more

    • Powerful Air Purifier
Style: 400 Graphite
A lot of research went into this, as I didn't want to spend over $500 but in terms of air filters and purifiers you get what you pay for. This really does clean the air. Set up is less than 10 minutes. I live in a rancher 1 story and placed it in the middle of my house. It does the job well. It can be a little louder at high speeds but not annoying, more white noise than anything. I placed my yard sneakers next to it... No socks shoes smell like death I eventually threw them away but when I placed them near the purifier it must of triggered the air quality sensor and started running. No joke this thing worked, I feel horrible that my shoes had the impact on air quality, now I know why my wife wanted me to get rid of them. We have a dog and 3 cats no animal or yard shoe smells in the house. Some advice; clean your house thoroughly before turning it on. Give the purifier a chance to maintain air quality more than fix it- dust and vacuum first. Make sure there is no blockage on each side (close to walls or other objects). Read the instructions that came with it, understand the functionality which best suits your conditions. I read other reviews about a plastic smell omitting from the purifier but i didn't get any of that. My wife has a sensitive nose, didn't notice anything like that either. Dust has been minimal also, most likely going to buy more Coway products maybe the smaller version for select rooms. Only downside which is not the fault of Coway is that my dog likes to hang her face above the fan, I don't know why-but she sometimes changes the speed and setting when she does it. I'm happy with this product, and would strongly recommend it. I don't know how it will impact micro organisms or germs but with what is going on in the world I'm willing to give this thing a shot and haven't been disappointed yet (1 month in) ... show more

    • Quiet and efficient
Style: 400 Graphite
I did a lot of review and research on air purifiers before purchasing this one. Although it is not the cheapest, it is also not the most expensive. I have a 1,200 square foot home with 2 large hypoallergenic dogs. There are only 2 of us here with the dogs so not a lot of dust being stirred up. However, we live in Florida and during the cooler months, like to leave the windows open and this is the time of year pollen is very high. We cook a lot at home and in a small house, odors can be overwhelming and linger. Well, that is all over! This machine is amazing! In smart mode it senses air quality changes and adjusts it cleaning rate accordingly. Within an hour or so of the house smelling of bacon, or garlic/onions, the odors are gone. The dust on our furniture has decreased significantly. Pet odors have been all but eliminated. The machine is small and unobtrusive. It is quiet most of the time but when on high can be a little noisy, about like a floor fan on high. That said, I think it kicked onto high once and for about 10 minutes. It is right next to our TV in the LR and I only had to increase the volume a tad to compensate. Overall, great machine! Does what it says it will do and won't break the bank. ... show more
