Coway Airmega 400 Smart Air Purifier
Cons: Inexpensive replacement filters that don’t remove VOCs.
You should seek for ways to improve indoor air quality if your home is full of smoke, dust, pollen, pet hair, and other waste. In addition to frequently sweeping and cleaning your HVAC filters, a good air purifier can assist you out.
I’ve been using the , a new model from one of the industry’s top companies.
CAD and spec
Available in white and graphite/silver. I tried the graphite variant, which matched my dining room’s darker tones. The device is 23 inches high and 15 inches broad and deep, so it doesn’t take up much area.
The 25-pound unit isn’t great for moving around the house to filter the air. If you want to move it, it has handles on both sides.
Here are some more vital specs:
Setup
The was a breeze to set up. I took the purifier out of the box, plugged it in, and it started working. It took roughly 15 minutes total.
Before turning on the Airmega, remove all plastic from the two Max2 filters on either side. This little task let me get to know the equipment. The directions are in the user handbook.
When you initially turn on the unit, it automatically switches to Smart Mode, which I’ll explain later. You may change the mode by running your finger along the touch sensor. In Smart Mode, usually.
What sets apart the air purifier
The performed a great job cleansing the air and is quite silent. When the is on low, the only way to tell it’s operating is by feeling the breeze. My sound meter measured 39 decibels at four feet, quieter than a PC. Sound meter reported 55 decibels with the fan on high, still softer than a conversation.
It worked best when I was frying in the kitchen, my wife was vaping inside, and I was burning incense — not all at the same time, that’d be ridiculous. When the purifier’s pollution sensor detected irritants, the LED turned red (unhealthy) and the fan accelerated.
I like the ‘s Smart mode and Energy Star certification. In Smart mode, the fan shuts off after 10 minutes of low pollution. When it detects contaminants in the air, it automatically restarts until the levels return to normal. This saves money on electricity.
The is easy to clean. The filter indication tells you when to clean the pre-filters, which is every two weeks depending on your home’s pollution level. I just use a hand vacuum to clean them. Coway also suggests wiping out the vents and the pollution sensor every two months to keep them clean.
Pros and Cons
The HEPA filter is the most costly part of an air purifier. Thes replacement filter set includes two filters and is now under $50 on Amazon. Although you only need to replace the filters every few years, it’s still a cost to consider.
The Coway 250 is the industry’s greatest air purifier. While it was comparable to our top recommendations, it wasn’t as successful at eliminating VOCs from the air as our top picks. See their guide for additional information on the best air purifiers.
In summary
Overall, I liked the . When I tested this in the spring, when pollen levels were high, I had less sneezing and eye irritation. The effectively removes vape clouds, smoke, and dander. Best of all, it’s so quiet I hardly know it’s on.
I highly recommend any of Coway’s air purifiers for fighting indoor pollution.
Which model to buy?
I recommend the or 400 for large spaces to remove allergens. The 200M is a good choice if you have a tiny space or wish to move the air purifier about. Consider the or 400S if you want your purifier to be smart home compatible.
