The Coway Airmega 400 air purifier is for sale


If you are looking at an air purifier, you’re in luck. Our favorite purifier for large rooms,, Coway Airmega 400, is on sale at a price of $ 381, which is $ 119 more than the usual price of $ 500. We pointed out at the beginning discount at Walmart it has lowered the price to a staggeringly low $ 220, but is no longer available. The contract with Amazon may not be the lowest price ever – it was a prepandemic – but it is the biggest drop since early 2020.

No matter where you live, an air purifier is GOOD IDEA. Even if the air in your enclosure doesn’t feel dirty, it does. External particles i volatile organic compounds (HOS) are breaking into our homes. Interior plastics and furniture emit harmful fumes. And there is always dust and dandruff of pets. With frequent vacuuming, an air purifier can help you get things done under control.

Updated July 8, 2021: The deal at Walmart is over, but there is still a discount on Amazon.

The Airmega 400 has highly efficient particle filters (HEPA) that circulate air in a room of 1,560 square meters twice an hour. If you use it in a smaller space, you can turn it on four times an hour. It can automatically adjust the settings based on the change in air quality in the room, so you don’t have to think about it. And on the front there is an air quality ring marked with color, so at first glance you know what the status of your room is.

It has a pre-filter made to capture larger particles, which you can wash, as well as a HEPA filter combined with activated carbon that will eventually need to be replaced – the purifier will alert you when it’s time to do both. They are easy to grab and pull out.
