Coway Airmega 400 Green True HEPA Air Purifier White: Energy Star Certified, 1200-1500 sq. ft. Coverage, 5-Year Warranty

This is actually the second Airmega 400 purchase I’ve made for the sole reason that I’ve been so happy with the first one. The first one I purchased in the fall of 2024. I own a large Blue and Gold Macaw Parrot who was constantly getting respiratory ailments. The vet recommended I look into purchasing an air purifier, which I did. However, they weren’t doing the job, as he was still getting ill at times. So, I did some more research and decided to go with the airmega 400 and I’m so thrilled I did! I’m delighted to say that he has not once had a respiratory infection since I made the purchase!

Quiet air cleaner, just works no bothers. The touch controls work once you get a little practice with them.

The unit has been working non stop for about 5 weeks now and is doing a great job. I have cleaned the dust filters about 3 times so they are doing they're job. It is also easy to move around from room to room.

This device is amazing. I was a sceptic and it’s proven me wrong with its black magic. Pass gas nearby… it kicks into gear. Burn your toast… say goodbye to smells. The filters show me just how much dirt and dust it’s removing. It is so easy to use, easy to setup, and makes me feel so much more confident in the health of my home.

Airmegas. I've had over the top air filters that pretty much do nothing more than the bottom of the line air filters. Air filters are quite simple, air in, filter, air out. How this is accomplished is what matters. I love Coway's Airmegas for 1. THE PRE FILTER SCREEN. It is ever so easy to take out. Magnetic side panels and simple click fins make it easy to clean and put it back in -- makes for weekly cleaning ease. It's incredible how much large particles these catch and how much longer a pre-filter screen can keep your pleated and carbon HEPA filter's life going longer and stronger. After you own an air filter with a pre-filter screen you can't go back to one without. 2. AFFORDABLE AND ROBUST HEPA FILTER. Just pop in a replacement cartridge every 6-9 months (depending on your situation) -- be sure to get genuine Coway brand. 3. QUIET function of these air filters, no matter what mode they are in = quiet. 4. NO WIFI (like do we need EVERYTHING connected? - no). 5. DESIGN...the design the design; actually looks good in your home. 6. FABRIC CORD, a tiny but lovely detail. 7. LIGHTS OFF OPTION on the air filter (the little level dots stay on but easy to cover. 8. LIFT SIDE HANDLE GROOVES on each side panel make it a breeze to move. 9. SUPER PACKING of the units. I have four of these, I've tried so many others. None compare and no damage in shipping. 10. THEY WORK. You will notice a difference in your home's air quality.

Excellent product which worth every penny with 4 level of setting. Highly recommended.

Best ever for asthma. I purchased this for when I stay at my fiancée parents house and was having issues. Now I wake up well rested and no issues at all. The build quality is impressive too

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.

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!

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