Survive allergy season with deep discount on the Coway Mighty air purifier

Allergy season is hard upon us and will continue to inflict suffering into November. To help you breathe easier at home, Amazon and Walmart slashed the price of the Coway AP-1512HH Mighty air purifier. The Coway is one of the best air purifiers you can buy, and as a Digital Trends reviewer wrote, the Mighty air purifier “punches well above its weight when it comes to value.”

Coway’s 4-stage filter system is the primary reason this air purifier leads the pack. The first stage is a washable pre-filter that removes large particles from the air including hair, fur, and dust. In the second stage, an advanced activated carbon odor filter traps harmful gases, bad odors, and smaller particles. That means step two removes cooking smells, musty odors, pet odors, and the gases from volatile organic compounds (VOCs) such as paint.

The Coway Mighty air purifier’s third stage is where many air purifiers start. A true HEPA filter traps 99.7% of the allergens and contaminants in the air as small as o.3 microns. So household dust, pet hair and dander, pollen, and tobacco smoke don’t stand a chance in stage three. The fourth and final stage is Coway’s Vital Ionizer, which cleans and freshens the air with negative ions.

LEDs on the Coway Mighty display the current air quality in your home. The control panel also has a timer and a filter life indicator for both the washable pre-filter and the replaceable HEPA filter. You can control the fan speed manually with three settings, but the Coway will control the fan speed for optimal operation when put in auto mode. In Eco mode, the purifier’s air quality detection automatically stops the fan to conserve energy if the Coway Mighty doesn’t detect pollutants for 30 minutes.

The Coway Mighty AP-1512HH was designed to clean the air in rooms up to 361 square feet. The Coway’s clean air delivery ratings (CADR) are Dust: 246 cubic feet, Pollen: 240 cubic feet, and Smoke: 233 cubic feet. The standard formula for translating CADR numbers into room size is to multiply each rating by 1.5. The Coway’s CADR ratings multiplied in that fashion average 360 square feet, the equivalent of a room that measures approximately 18 feet by 20 feet.

The Coway AP-1512HH Mighty air purifier is an Amazon customer favorite, with an average 4.4-star rating on a 5-star scale from 1,390 customer reviews.

Amazon usually sells the Coway AP-1512-HH Mighty air purifier for $223, and Walmart lists its regular price as $253. Both merchants have the Coway Mighty on sale for $162. If you’re looking for a great deal on a powerful air purifier, take advantage of this deal.

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.
