Coway Airmega 400/400S Air Purifier Replacement Filter Set, Max 2 Green True HEPA and Active Carbon Filter, AP-2015-FP

Highly Effective Original Filters
We’ve been using these replacement filters since 2017 for our two Air Mega 400s, alongside two other large air purifiers from a different brand. These original filters are outstanding and do a much better job of keeping our home’s air clean compared to aftermarket options (we use air quality sensors to monitor particle levels). After trying a few non-branded filters, it was clear they couldn’t match the performance. Stick with the originals and be rest assured about the quality of air in your home (or wherever you’re using your 400/400s).

You Get What You Pay For
The whole idea behind buying an “air scrubber” as I call them is to purify the interior air. So why would one spend all that money on a Coway and only to go cheap on the air filter system? Yeah, shop around Amazon. There’s cheaper no-name filters out there definitely. But what’s the point? The filtration system is just as important as the built in detection system as they’re designed to work in unison. These filters are the “real deal”, certification and lab testing and all. And besides that, it’s not like you’re replacing them every month. So for me to invest and additional $100 per year and have peace of mind knowing it’s doing what the filters were originally designed to do is worth it. And this is the cheapest place here I’ve found for these factory replacements too. Two thumbs up from me.

Essential Replacement Filters for Clean Air! just a bit pricy..
I’ve been using the Airmega 400 for a while, and this Max2 filter set is an absolute must-have to keep it working at its best. The combination of the carbon and HEPA filters does an excellent job of trapping odors, allergens, and other pollutants. After replacing the filters, I can immediately notice the difference in the air quality in my home—it feels fresher and cleaner, which is great for my family and pets.The only downside is that the filter set is a bit pricey, especially considering it needs to be replaced every few months depending on usage. While I understand the importance of maintaining the air purifier, it would be nice if the price was more affordable since it’s a recurring purchase.That being said, the filters are easy to install and fit perfectly into the unit. Despite the cost, I still think this filter set is essential for keeping your Airmega 400 running efficiently and ensuring your home stays healthy and clean. Highly recommend, just keep the price factor in mind!

OEM
The Coway store on Amazon is not ran by Coway, but by Amazon which you can tell by where it comes from in addition to there being the official store link. Amazon buys a lot of product of whatever they think will sell to allow much faster delivery of goods. They don’t buy knock offs and sell under the Company name so you can trust these filters are legit and much cheaper than from Coway as Amazon pays much less to buy bulk which then translates that savings to the consumer as well. In addiiton, the merv 13 rating is a typo it’s merv 17 according to Amazon themselves. The filters specification numbers don’t filter to the same specifications you see on the machine because it’s a collective process of filtration so that’s why it seems like they aren’t the same…remember their machine setup and the pre filter adds to those filtration numbers.

These are great and last longer if you clean them.

I have been using HEPA filters for many years; the price of this set is actually quite reasonable. Please note however that their life span will vary depending on how you use your machine and where it is located. My Airmega 400S is near the kitchen and I keep it at level 3, 24 hours a day, so they last about six months.

Quite happy to have this during the wild fire and pandemic also.
