Coway Airmega 150 is a shoe box-sized air purifier that’s big on power

Everyone wants cleaner air, but the problem is that most air purifiers are large. Too large. If you live in a small apartment where space is at a premium, you aren’t going to want a huge machine taking up lots of space. Coway hopes to solve that with the Coway Airmega 150, a compact smart air purifier that’s about the size of a shoebox.

The new Coway Airmega 150 is designed with smaller spaces in mind, but it doesn’t trade efficiency in exchange for compacness. The device uses a multistage Green True HEPA filter and eliminates 99.97% of airborne particulates as small as 0.3 microns in size. This includes dust, pollen, and smoke, making it a fantastic choice for the fall and winter seasons when allergies flare up and many people have fires burning in their homes.

The sensor atop the Airmega 150 will tell you the quality of the air at a glance, and the LEDs on the machine change colors to reflect the quality of the air in real time. The Airmega 150 has three different speed settings that allow you to control both its volume and the speed at which it cleans the air.

The control panel on top of the Airmega 150 allows you to control whether the light is on or off, as well as toggle between auto mode and fan speeds, and will inform you when it is time to swap out the filter. Speaking of filters, it includes an easy-to-remove washable prefilter that will extend the life of your filter with regular cleaning.

The Airmega 150 is 13.4 inches by 6.5 inches by 18.5 inches, making it compact enough to fit in almost any space. It is rated for rooms up to 214 square feet, so while it may not be the best option for purifying the air in your living room, it’s a perfect choice for the majority of bedrooms (and some studio apartments.)

Customers can also choose between multiple color options: Sage Green, Dove White, and soon, Peony Pink. Who says that practical devices can’t be stylish?

The Coway Airmega 150 is available today from Coway’s website for $190 in Sage Green and Dove White. With fall allergy season in full swing, it is the perfect time to consider investing in an air purifier to improve the air quality around your home.

Can you run an air purifier and essential oil diffuser at the same time?
URPOWER Essential Oil Diffuser.

At first glance, air purifiers and essential oil diffusers seem like they would be natural opponents. One is designed to take particles from the air in your home, and the other is designed to add (pleasant-smelling) particles instead. If you’re running them both in the same room, it’s understandable to wonder if they’re canceling each other out.

Fortunately, it’s easy to clear this confusion up. Let’s take a look at some FAQs about these two home air devices and what you should know about using them both at the same time.
What's the difference between an air purifier and an air diffuser?
An air purifier uses a filter or series of filters to remove unwanted particles from your home’s air. They are commonly used to get rid of airborne allergens, smoke, and dust, and they can also help remove bacteria and viruses from the air. The best air purifiers use true HEPA filters that can remove particles down to the size of 0.3 microns, and some newer models can remove particles as small as 0.1 microns.

How long do I run my air purifier?
The Coway Airmega purifier.

In previous guides, we’ve discussed how today’s smart air purifiers work and what specs to look at when getting the right size for your room or house -- like CADR, or Clean Air Delivery Rate. But air purifiers can only cycle through a room’s air when they are turned on … which leads us to another important question: Just how long should you run your air purifier? Can you run it for too long? Don’t worry, we have all the answers.
How long should I run my air purifier?
The air quality inside your home is always changing, and the impact of your air purifier will depend on its size -- especially whether you want to clear up a single room or the whole house. In general, you can run an air purifier for a few hours a day and expect it to give the air in its space a thorough cleaning. If you’re only looking at one smaller room, half an hour to an hour can have the same result. That schedule can give you all the benefits that an air purifier offers without requiring it to be on all the time -- but you’ll want to run it at least once a day for best effect.

Do air purifier settings make a difference when running it?
They do. Most air purifiers have several fan settings that affect how quickly they push air through, in exchange for using more power and making more noise. If you only have a few hours a day to clean the air in your home and would prefer not to leave the purifier on when you are away, turn it to its maximum setting and let it run. Just note that max settings on most air purifiers will be too loud to hold a meeting in the same room.
Is it safe to run an air purifier all the time?
Yes. Air purifiers are generally designed to be run all the time if you prefer to. You can put the purifier on its lowest setting to diminish noise and let it run throughout the day.

The new Wyze Air Purifier offers quiet, efficient filtration
The Wyze Air Purifier is quiet enough for use in any room.

Wyze has announced a new air purifier with three different filter options. You can choose which filter you want at purchase, but the other filters can be purchased at a later date and swapped out on the fly as needed.

The Wyze Air Purifier filter options include the Allergen (Standard) filter, the Formaldehyde (Premium) filter, and the Wildfire filter. It utilizes a true HEPA filter for 99.97% efficiency in eliminating harmful, airborne particles such as dander, pollen, and even smoke. The purifier has enough power to clean a 500-square-foot room up to three times an hour, and it's not too loud even on the highest setting. The sound ranges from 21 decibels in its sleep mode to 54 decibels on its highest level -- roughly the same volume as a refrigerator's hum.
