2 Set 400/400S Replacement Filter Compatible with Coway AIRMEGA Max2 400 400S 400(G) 400S(G) Air Purifier, Max2 Green True HEPA and Active Carbon Filter Set, AP-2015-FP

We run our air cleaner around the clock and the filters can get expensive. These are a good value.

These are great filters, and it's great to get 2 sets at once! - these look like they're made very similarly to the original and they fit just as well. Given how expensive OEM filters are with Airmega, these actually gave me the confidence to buy a second Airmega 400 purifier, knowing that the filters would be affordable into the future.That, and these don't have the chemical smell that seems to have plagued Coway's replacement filters lately. I had to return a set because those ones just wouldn't air out.Companies like Smilyan will be my go-to in the future if they keep making great options. Nice!

The original filters for the Airmega are pricey. These are similar quality for much cheaper. Similar size, build quality, carbon, etc.

These are almost the same exact thing as the Conway-branded filters.The fit is perfect. They seem to weight the same amount. The honey-comb pattern for the activated charcoal is slightly different (this product has circles) but the volume of activated charcoal used is the same and the shape of the charcoal used is the same. Even the foam that goes around the edge of the filter and forms a seal seems to be the same.The image printed on the side is different.The Conway-branded filters retail for $130 for TWO filters (but at the time of writing is on sale). These are currently $50 (with a $5 coupon applied) for FOUR filters! That is $12.5 a filter vs $65 a filter.Even if the filters aren't technically the exact same - even if the Conway filters are somewhat superior in some way... you will certainly have a better overall experience by changing the filters multiple times vs a single use.I waited too long to replace these filters - specifically because of the price. I vacuumed the dust off the charcoal side, and assumed they were still working fine. However, as soon as I dropped the new filters in the change was apparent. It seems that activated charcoal only has a certain lifespan... so even if the filter isn't clogged up with dust, it stops being as effective as it was.This machine was rather expensive. It doesn't make sense to hamper its effectiveness with old filters. I wish I had ordered these replacements sooner. Extremely pleased with the prodcut.

I'm liking this replacement set at this price point. The previous non-OEM filters only lasted about 4 months before they were loud and another 2 months before the change filter indicator came on. That's not good because OEM filters last 12 months so that's double. I'll keep an eye on this one but so far the filter is very quiet and seems to be doing a good job. 5/5 stars.

This filter set is a perfect replacement for the 2 filters in our Coway AirMega 400s unit. They look and perform the same too. The filters were shipped individually packed in a plastic enclosed bag.Great alternative to the OEM variety at a fraction of the cost.

For some reason my 400s get dirty so quickly. I didn’t think our air was so nasty but it does a great job filtering all the garbage out of the air. You really have to replace the filters often, these filters are a perfect fit. They are easy to just pop in and the airflow is the same as the oem filters. I am hoping these will last a while but we seem to go through any filter quickly. I love that you get 2 sets of filters, it will help not having to get new ones for a while. Overall, they seem like a pretty decent filter option.

These seem very high quality! They're a great fit and much heavier than other generic filters I've tried. Many generic filters are incredibly light, but not these. They come in a hefty box, and when held to the light, not a lot of light gets through. Without the ability to air quality test, this suggests that they have a much more heavy-duty HEPA filter than other competing filters.The only downside is the carbon filter. The Coway filters have a hexagonal/honeycomb mesh and each cell is absolutely packed with activated carbon. Here, the carbon is contained in circles (leaving gaps between) and each cell is about half full of activated carbon. I'd like it just a little better if the gaps between were filled, even if it would affect its intake ability.As a value proposition, it's an excellent value and appears to perform great. If it fails prematurely, I'll let you know, but given its snug fit and hefty build, I really don't expect it will. It doesn't have the carbon content (and smell reduction) of the Coway brand, but for the price, I think these are a good compromise.
