Yes, I farted next to it.
I bought this and another product because my husband and FIL has really bad spring-summer allergies. It worked SO WELL. The design is great, doesnt take much space and can put in the corner. It is not loud unless you use it at it's full strength, but it sounds like the wind, not a machine made sound. Air quality and cleanliness, AMAZING. My husband and I tested by, yes, farting next to it. It cleared up so fast. Absolutely worth the investment and I bought 2 more (on sale, cant afford full price) for my family because they are allergic to everything and their pets are also allergic to Texas pollen.

Small and effective
This little guy works incredibly well. We don’t have a true exhaust vent over our stove, and got this to sit on the fridge and manage whatever the recirculating vent built in to the over-the-range microwave can’t handle. We leave it on the automatic setting and it does a great job ramping up while we cook and then going back to the low setting once the air is cleared. I like that you can turn off the status indicator lights, and being able to just hit the auto button means it’s easy to use, no fiddling with settings. It takes care of strong cooking odors and was worth every penny. We also have two other Coway air filters and they have lasted several years so far without any problems.

quiet, compact and I am breathing better
I have acquired an allergy from my cats dander and also from dust. I did a lot of research before deciding upon and purchasing this air purifier. Compared to other air purifiers that marketers have hyped up the quality of HEPA air filters that they use, this one contains more of a carbon filter and was rated higher in performance. It fits perfectly in the corner near our wood burning fireplace which also can emit ash dust. It is also quiet. I noticed the difference in my breathing since buying this air purifier.

Works well. Big help with the air quality.
Happy with this air purifier. I use it every day almost all day. It showed orange ( poor air quality) for about the first 3 days. !!! It reads blue (healthy) from here on out. It has 4 speed/levels, a timer and night modes. Filters seem to last a long time. It’s pretty quiet. Noise level raises a bit as you go up a level. Can’t hear it on the lowest level while sleeping. Have definitely noticed much better air quality in my very large bedroom.

NY Times Top Pick
My allergist suggested I get a Air Purifier. Gemini suggested I get this one. The NY Times seems to really like it. It seems to be working. My allergies are better, but it could be seasonal. Five stars because it is well built and quiet. I like the night mode.

Works great, sort of a dust collector though
Purchased for new baby. I have noticed that our room stays dust free longer and food smells from the kitchen don’t linger as long. I enjoy the soft glow as well. Only issue is, when dust does start to collect, it sticks in all the slots at the top of the machine and can be hard to clean every single one.

Air Purifier Filter Replacement Icon blinking. No help from Coway Support!
I bought this only 4 months ago and already the light was flashing to change the filter. This is impossible since I've been vacuuming the filter on a regular basis to make sure it's clean. I tried calling Coway but NO ONE EVER ANSWERS THE PHONE! I was on hold 3x for more than 30 min and still no one picks up. This person named Fernando keeps emailing that I should hold down the change filter button until it goes off and then put it back on. I said that will be like I just changed the filter and it's resetting, but then how will I know I really need to change the filter? He goes back and forth telling me the same thing, does not offer any other troubleshooting or help in maybe replacing it, or giving me a refund! There's a 3-year warranty but had can it be honored if no one answers the phone or offers any help?

Helps with cat odor and dust
I use to have a much smaller air purifier and needed an upgrade. This was a huge one. It's in my room where my cats love to be the most and i have more than 4 so it's honestly a blessing. I unfortunately have to have a litter in my room due to my cats anxiety so it can start to smell pretty bad really quickly but with this air purifier, the smells are nonexistent. I clean the litter every other day or every few days and besides the smell, it collects a lot of dust that helps me with allergies. Although it is pretty pricy, it covers a huge amount of space and has many features especially if you want to keep it on for sleep. The sleep mode is really nice along with light features if the brightness bothers you. I personally really enjoy the quality and how it works and am so glad I got it when i did!

actually surprised at how efficiently this filtered the air. i have it normally running on sleep-mode during the day and it's ultra quiet so the sound not noticeable (the light indicator reminds me it's on). if i need a quick 'boost' of clean air, i let it run on max for about 15 min then back to sleep-mode for normal operation.

I definitely notice a difference in the amount of dust and cat hair in my room/ basement, I do feel it helps with my allergies which was the reason for purchase. I appreciate the sensor and light that indicates air quality. The automatic feature is great, pretty much the only feature I use as it adjusts speeds as needed, which isn’t often as it does a great job at maintaining consistent clean air. Wish it had Bluetooth but that’s something I can live without, especially given my overall satisfaction with the product. Just don’t forget to vacuum the filter every now and then as it’s supposed to last a year. Will update after the year mark if I remember 😆
