Coway Airmega 400 Green True HEPA Air Purifier

I have had many smaller air purifiers but never felt they could handle our larger open space kitchen and living room. This coway is excellent. Super quiet and honestly the best I have been able to breathe in my home in a decade. Worth every cent. Looks sleek too

Great product, happy with both the aesthetic and the sound level. Has a noticeable impact on allergens for our family indoors.

Thank you for the missing filters. I appreciate you sending them. This is a great unit now that I can operate it.

I own two of these, and they are fantastic and do exactly what you need them to to eliminate things like smoke, pollution, dust, and keeping coworkers healthy. Every office should have these all over them

I love this purifier. It is SOOO much quieter than my BlueAir and very easy to clean. I have used the Airmega 300 for my bedroom and so purchasing this Airmega 400 was a no brainer. What made the purchase even more attractive was the sale price. I would recommend this and similar Coway purifiers to anyone who suffers from allergies, or who just works around a lot of dirt/dust.

Runs great and very quiet. Took away the musty smell in the basement

I’m so impressed with the build quality of my new AirMega 400! 
I did a lot of research before purchasing my Air Filter and based upon best value for my investment, I overwhelmingly chose Coway. Even though I was expecting a quality item, after receiving and setting it up, I was still amazed at how well engineered it was. The fit and finish were perfect. The combined hepa, charcoal filters fit perfectly snug ensuring no leakage of air. The dust screen snapped in and out easily and the outer panels, held by magnets, were a snap to remove & replace. The use of carbon pellets instead 
of sprayed on carbon also demonstrates Coway’s commitment to quality. I’m a 75 year old retired senior citizen, who remembers well when products were built with quality, performance and pride. It is so encouraging to see a company like Coway bringing back those qualities I so admired.

Extremely loud rattle on low and medium speeds. The whole thing shakes.

This air purifier works exactly as advertised. It is very quiet when on and has a variety of options to best suit the space it is going to service

Excellent unit. Started working right away and I can’t stop gushing over it. Works so well, already can tell a difference in air quality.

I love everything about this air purifier! I appreciate the smart mode that automatically adjusts as the air quality changes. The air purifier was easy to set up and has been simple and intuitive to maintain.

Works well !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Outstanding piece of equipment! Performs as promised, and then some. More than happy with this product!

love the unit, but doesn't seem to work with the app, which is disappointing. still have no idea how to register since I can't do it from the app. so the unit is 5 stars ... the app is 0 stars.

It was beyond my expectations. I'm pretty satisfied with the Airmega 400.

Airmega 400 - Graphite is AMAZING. I am so very happy I purchased this air purifier. The air purifier is easy to use and looks perfect in my living space. The Airmega 400 cleans the air and removes odors! I have allergies and live in a densely populated area, with alot of pollution from cars and people. I would defintely recommend this product. Five Stars for Airmega 400!

Noticed a big difference with the allergies and decreased need to dust furniture.

We have a full basement which is partially finished. It always smelled and the air old. Well until this wondrous Air filter. WE LOVE IT! We go down to wash clothes and store things now with pleasure.

I bought this for my room with litter boxes. It filters the air well and there is significantly less dust in the room. The odor is generally well controlled for a smaller room. I have two of them for my house and they are worth it! I would wait to buy when they are on sale.

I've been running this unit for 2 weeks on level 2. I believe it is making a difference in my house that stinks of old cigarettes and hound dogs. Hoping that it lasts a long time!
