Thanks to Deal Hunter phoinix for sharing this deal.
Product Details:
- Designed to clean spaces up to 3,120 sq. ft. in 60 minutes
- Combination of a pre-filter, active carbon filter, and HEPA Filter reduces 99.97% of 0.3 micron particles, including pollen and other allergens. It also reduces volatile organic compounds and odor
- With its Smart Mode feature, the Airmega automatically adapts to its surroundings by adjusting fan speeds based on the room's air quality; That means your unit is energy efficient without compromising effectiveness
- When the air quality in the room remains purified for 30 minutes or more in Eco Mode, the fan will turn off to conserve energy, kicking on again when pollution is detected
- When the Airmega's built-in light and pollution sensors detect that the room has been dark and the air clean for 3 minutes, Sleep Mode reduces the purifier's noise and power consumption

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.

I purchased this, and like my smaller coway iPod-looking-units for the bedrooms will get non-oem filters, but want decent ones even if they aren't the cheapest.
Thanks!

It'd significantly reduce it, but you'll have to change the filters a lot more than the recommended amount
