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

$109 stings every time, but these OEM filters keep my Airmega 400S running perfectly. Just replaced after 10 months of running 24/7. Super easy swap - pop the sides, slide out the old ones, slide in the new. My old HEPA filter was brownish-gray (started white), and the carbon prefilter was completely shot. The difference was immediate - air smells fresher, unit runs quieter, and my allergies cleared up within a day. These things work. Just budget for replacements every year or so.

Bought these as replacement filters for our air machine. High quality and just as good as the originals. We have several of these throughout our house, so are frequently in need of filters. They do great at removing all kinds of dust and other stuff from the air.

Some things are always better OEM. Not cheap, but work well.

Works as intended. I agree with others, it's a bit pricey, but it slots in snug and it filters well.

Pricy as hell but do indeed work superior to aftermarket

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!

I only buy the filters from the manufacturer of my air cleaner. Filters arrived quickly.

Fits and is supposedly the OEM filter. Just wish they were less expensive

This original Coway filter is the way to go if you want to keep your area clean. Cheap non original filters are horrible compared to those Coway original filters.

Really great in pet friendly homes

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

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.

These are great and last longer if you clean them.
