Highly Recommend!!
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!
Thank you so much for sharing this incredible experience. We’re truly honored that the Airmega 400 has made such a meaningful difference for you and your Blue and Gold Macaw. Knowing that your first unit helped support his respiratory health—and that this led you to purchase a second—means a great deal to us. We design our purifiers to handle challenging environments, and it’s wonderful to hear how well it’s worked for your home. We appreciate your trust and wish you and your feathered friend continued health and comfort.

The BEST air filters available.
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.
Wow—thank you for such a thorough and passionate review! We’re genuinely honored that the Airmega 400 has earned a place in your home (times four!). You’ve captured exactly what we strive for: thoughtful design, reliable performance, and user-friendly features that make a real difference. From the magnetic pre-filter panels to the quiet operation and fabric cord, it’s clear you’ve noticed the small details we obsess over. We especially appreciate your shoutout to the simplicity and effectiveness of the filtration system—air in, air out, done right. Thank you for being such a dedicated Airmega advocate. We’re so glad it’s helping you breathe easier!

Magic!
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.
Thank you for sharing such a fun and thoughtful review of the Airmega 400! We’re thrilled to hear that it’s exceeded your expectations and proven its value in keeping your home fresh and clean. From tackling everyday odors to showing just how much dust and dirt it removes, it’s great to know the purifier has made such a noticeable difference. We’re delighted that setup and use have been easy and that it’s given you more confidence in the health of your home. If you ever have questions or need support, please don’t hesitate to reach out to us at Info@cowaymega.com. We truly appreciate your trust in Coway.
