This last time I spent the money on Coway filters and can say I am happier. ultimately worth the price. I can tell the air is 'lighter' when I change the filters. More so than when I'd change out to aftermarket. The carbon also lasts a LOT longer. There is a smell in the air when the carbon stops working. It's distinct. The carbon in the Coways easily last twice as long. But this isn't a deal breaker. As the carbon in the Coways don't last as long as the HEPA part either. You can give them a good shake, to extend the life of the carbon. Doing so introduces new cracks and crevices within the pieces of carbon for the air to filter through. Be sure the vacuum it first. Shake with the carbon part of the filter pointed down. And vacuum again afterwards. Because you will get carbon dust, it's just little pieces of charcoal, all in your HEPA, reducing the lifespan.
Community Reviews
The Coway Airmega 400 is a large, smart HEPA purifier that moves a lot of air and does a strong job cutting dust, odors, and airborne particles. It works well in bigger spaces, can run around the clock, and the auto sensor and scheduled high speed mode help it collect plenty of debris on the prefilter. Long term durability looks solid, with multiple reports of years of trouble free use. The main drawbacks are expensive replacement filters, especially for the pair, plus occasional complaints about chemical smells, noise, WiFi setup hassles, and no child lock. A capable whole home style purifier if upkeep cost and size are acceptable.
Common Questions (5)
It works well in a bedroom or main living area, but it is not ideal for moving air between floors or across a whole house. A common recommendation is one unit per floor or multiple smaller units for large, separated spaces.
The HEPA/carbon filter set is commonly replaced about once a year, though some owners stretch it to 9 months to a year with regular pre-filter cleaning. In cleaner homes, genuine filters may last 3-5 years with minimal performance drop, while the carbon portion usually wears out sooner than the HEPA media.
Aftermarket filters are widely used and can work fine in the Airmega 400, with several owners reporting no noticeable difference in day-to-day performance. The main caveat is that some off-brand filters may have fewer pleats or less carbon, and using third-party filters can affect warranty service if a problem is traced to them.
It can be quiet on low, but some units develop a hum or whine at low speeds and get noisy above low. Replacement filters have also been reported to smell chemical-like, including OEM filters, so checking recent filter reviews before buying is useful.
The WiFi/app setup can be finicky, and after a power outage it may lose connectivity and need a hard reset and re-adding to the app. The non-WiFi version avoids that hassle, while Alexa control is also available on the smart model.

I do like the unit on this deal. If filter cost is high, I won't bite. I'm fine with upfront cost for a nice unit, but the filter cost is what'll add up.

Honestly, if you have big rooms throughout your floors, get multiple of these devices.
Would not hesitate to buy one of these again if I needed a 2nd.
