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 air purifier that does a strong job clearing dust, odors, and visible haze, with auto mode and scheduling that can keep it running quietly in living spaces or bedrooms. Long-term reports are excellent, with units still working well after years of near-constant use, and the washable pre-filter helps stretch maintenance. The main drawbacks are the high cost of replacement filters, especially because the unit uses two, plus occasional complaints about chemical smells, noise at higher speeds, and app or WiFi hassles. It is a capable purifier if you can live with the upkeep and size.
Owners who plan to keep a purifier running continuously for years, because it has stayed reliable through 4 to 10 years of near-constant use.
Shoppers comfortable using third-party filters, because compatible aftermarket replacements can work well and keep annual upkeep lower.
People managing dust, pet hair, or visible haze in a living space, because scheduled high-speed runs and auto detection pull a lot of debris into the pre-filter.
People who want a purifier with automatic air-quality sensing, because it adjusts speed on its own and reacts quickly to odors and pets.
Households wanting a bedroom purifier that can run quietly overnight, because it stays silent enough for sleep and can be set to low at night.
People sensitive to chemical odors, because replacement filters and even the unit itself can smell strongly on arrival.
Apartment dwellers or multi-floor homes expecting one unit to cover everything, because it does not do well between floors and enclosed spaces.
Families with small children or cats near the controls, because there is no child lock and pets can press buttons or change settings.
Shoppers who want strong airflow without noise, because it gets loud above low speed and can produce a hum or whine.
Buyers who need easy WiFi control after outages, because the app setup can be finicky and may require a hard reset to reconnect.

Also as someone that works in a cleanroom, specifically micro contamination department, there is a big difference in cheap and expensive filtration. The carbon in the OEM filters in these is far better and the filtration media itself is better. You may not be able to tell a difference but its there. If your happy buying the cheap filters than do it.
Also as filters get dirtier that actually filter better, they just lose efficiency and cause the unit to work harder to pull air through it cause more wear and tear on the unit. The carbon media does have a lifetime though but its dependent on VOC exposure. No real way to test that without proper VOC testing.
That said, it's a great air purifier. I've had it for 2 years with no issues.
