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.

Clean air even during home renovation
I had this air purifier turned on while construction (drywall replacement, huge part of wall) was being done in my home and it filtered a significant amount of particles out of the air. I am extremely impressed. It keeps dust to a minimum in a typically dusty area. The night feature turns off the light and reduces the sound so I cannot even tell it is in the room with me.

4.5 Stars
Great air filter, works well in apartment/townhouse, especially for days/seasons I don't want windows open. I have one for upstairs and one for down. I sleep with it on and during the day rotate it in different rooms (is lightweight). I like the auto feature where it automatically changes speed based on air quality, and I set the timer if I'm not in the room. Overall the air is fresher, it works when cooking/smoke/ventilation needed. Only 4 stars because it's not a miracle worker if something is extra stinky (cats), that takes time.

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 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.

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!

WASTE OF MONEY
I bought this because I live in an apartment complex and have the misfortune of living above a pair of heavy smokers. Obviously nothing can be done about the structural integrity of the building, so I bought this air purifier in hopes it would at least minimize the smoke stench. While I didn’t expect the air purifier to eliminate ALL of the smell, it does almost nothing; I’ve been running it full blast for a week and haven’t noticed any reduction of their smoke smell. Super disappointed because I’m at my wit’s end. I feel like I’ve wasted my money.
