Coway AP-1512HH

Compact and Mighty

To ensure higher filtration capacity, air purifiers for larger areas are often pretty bulky. Yet, in Coway, they did their best to combine compactness and power in their latest air purifier model. Small and mighty are the words that will perfectly describe the Coway Mighty AP-1512HH. Let’s look at it in more details.

At a glance, you’ll notice that this air purifier is more compact than many other models in a similar range. It has a smaller footprint and a slimmer profile, thus, taking less space and perfectly fitting furnished areas. Yet, smaller dimensions in no way compromise the device performance. You’ll be surprised to find out that this air cleaner provides 360 sq.ft. of coverage with the certified clean air delivery of 232. So, it can purify the air in medium to large premises and open areas really quickly. Hence, the Coway Mighty name is self-explanatory.

The unit cleans and freshens the air through a 4-stage filtration system certified by the British Allergy Foundation. First, the sucked air passes through a washable micro-mesh pre-filter that captures larger dust particles, fur, and hair. Next sits a carbon filter that locks in odors, harmful gasses, and smaller particles. It is followed by a true HEPA filter that traps 99.9% of allergens and contaminants as small as 0.3 microns leaving no chances to pollen, dander, and tobacco smoke to escape. In the end, the branded Vital Ion feature enhances the purifying power and refreshes the air with negative ions.

To adjust the appliance operation, you can use intuitive controls on the top panel. You are free to choose between three fan speeds to set the desired airflow intensity while a 1-4-8-hour timer will let you conveniently set the operation time before the unit automatically switches off.

Review of Coway AP-1512HH Mighty Air Purifier with True HEPA and Eco Mode

Smart and Stylish

Along with the high-end filtration process and solid basic functionality, the Coway Mighty boasts a thoughtfully selected number of smart options that optimize the device operation and the final cleaning performance. Thus, an intelligent air quality indicator on the control panel applies particle sensor technology to monitor the air quality and displays the results in real time by changing colors. Blue color indicates that the air is clean, purple shows that it is medium polluted, and red stands for heavy pollution.

In addition to manually adjustable fan speeds, the model boasts an auto mode that will automatically change fan speeds depending on the level of air pollution. And if no pollution is detected within 30 minutes, the appliance will switch to Eco mode to save energy. Meanwhile, a filter indicator will signalize when it is time to check the pre-filter and replace the HEPA filter. The last but not the least, the Cowat comes packed in a sleek and stylish design available in black and white color patterns. It won’t stick out like a sore thumb and will perfectly blend with any high-tech, fusion, loft, or contemporary style.

To wrap things up, the Coway Mighty air purifier provides the best of what air cleaning technologies have to offer and will suit open spaces, dining rooms, and even studio apartments.

Guardian Technologies Air Purifier

On the Guard of Fresh Air for Allergy Sufferers

Reside in the region with a high level of air pollution or have allergy sufferers in your family and seek to improve the indoor air quality? If so, the Germ Guardian AC5350B air purifier is definitely worth your attention. At a fairly reasonable price, it offers excellent functionality and up-to-par cleaning performance. See for yourself.

First and foremost, what makes this model stand out is a thought-out filtration system it comes complete with. The unit applies a four-stage filtration process to make your home air both feel clean and smell clean. Thus, a standard washable pre-filter traps larger dust particles and pet hair to ensure efficient coarse filtration and prolong the service life of fine filters. It also features an activated charcoal layer meant to absorb and neutralize foul odors and smoke. Next to it is a true HEPA filter that captures pollen, pet dander, dust mites, mold spores, and other allergens as small as 0.3 microns. Overall, it removes up to 99.97% of potentially harmful tiny particles from the air. Yet, to maintain consistent cleaning performance, HEPA filter needs replacement every 6 to 8 months. And a special filter replacement indicator will give you a hint when it’s time to do that.

The final filtration stage is a UV-C light technology that works to kill airborne germs and dangerous viruses such as staph, influenza, pneumonia, and rhinovirus and activates titanium dioxide to combat volatile organic compounds and remove any remaining bacterial molecules. So, a nice blue-lit ring on the front panel of the unit is more than a decoration or a night lamp. Besides, this UV function is optional and you can turn the light on only to sanitize the room when necessary. As such, this air purifier leaves no chances to those allergy triggers on a prime allergy season and is a highly effective added protection against seasonal viral diseases.

Review of Guardian Technologies Air Purifier Germ Guardian for Large Rooms

A Perfect Match for Smaller Areas

When it comes to the coverage area, the Germ Guardian air purifier is rather on the smaller side. However, for mid-sized and smaller areas up to 167 sq.ft. it will do its job really great. The unit will clean the air about four times per hour with the CADR of 127 for pollen and CADR of 114 for dust, which is more than a decent cleaning rate for the specified coverage. Meanwhile, 5 variable fan speeds will let you adjust the air circulation intensity depending on your preference and the level of air pollution. And an 8-hour timer is there to set the appliance to run for a specific time period.

One more distinctive benefit of this model is a close-to-silent operation. At the highest speed setting, the level of noise will hardly reach 50dB while at lower settings, the air purifier will emit mild white noise that even helps people fall asleep, which makes it a perfect choice for bedrooms and nurseries.

It also pays to mention that the Germ Guardian looks very stylish and aesthetically pleasing. An all-black tower design will seamlessly blend with any modern interior while its slim profile will ideally fit even into cramped spaces.

To cut a long story short, the Germ Guardian AC5350B is an elegant and highly efficient air purifier for smaller households that will become a real find for allergy sufferers and areas with increased air pollution.

Comparison of Air Purifiers

What Is an Air Purifier?

The problem of pollution is getting worse and worse these days. All those substances, emissions, fumes, and other excessive pollutants emitted in the air inevitably lead to respiratory irritations and breathing issues. What's more, dust is just as dangerous. If accumulated in large amounts, it can trigger allergies and serious respiratory diseases in people susceptible to health problems caused by air pollutants. Therefore, clean air is crucial to living a healthy life, and that’s where an air purifier comes in.

Such devices as air purifiers were invented to protect people not only from the negative impact of dust and gases but also from pet dander, harmful bacteria, pollen, fungi, and various residential odors. air purifier systems operate in a simple way - they consist of a set of filters that provide various degrees of cleaning and a fan which pulls in the air for cleaning. But the effect they bring is invaluable, especially for those who suffer from some kind of allergy, asthma or chronic respiratory diseases.

Keep note, though, that residential air purifiers neither drain nor humidify the air in the room. If you seek a device for these purposes, check out our reviews of air humidifiers or air washers.

What Features to Compare

Filters and Filtered Substances

First things first, before choosing an air purifier, take a look at what type of filters it uses and what substances it can clean. If you have a budget, we recommend choosing among air purifiers featuring a 3-stage filtration system with three layers of filters. Those are considered the most effective, capable of capturing the smallest particles of dust, bacteria, mold, etc. Besides, they are long-lasting and cost-effective. Let's take a look at the types of filters which can be used in purifiers.

HEPA-filter is the standard for air purifiers, allowing the device to remove up to 99.97% of particles and pet dander from the air. HEPA filters are perfect for people who suffer from allergies, asthma, or any other lung diseases, plus they are long-lasting since they can be easily washed when too much dust collects, thus extending their lifetime.

Activated carbon will effectively remove foreign odors from the air. Not only does it purify the air but also it absorbs tobacco, gases, as well as food and pet odors with ease. You can also consider air purifiers that come with activated carbon mixed with baking soda. Those will provide even better results.

There are also air purifiers with UV lights. The benefit of air purifiers with UV lights is that they allow killing harmful airborne pollutants, such as germs, allergens, viruses, and bacteria, so you can use them for domestic disinfection purposes as well.

Along with the mentioned types, you can find air purifiers offering the functionality of a humidifier. As a result, they will help not only maintain the optimal humidity level in the room but also clean it from polluting particles as well as absorb unpleasant smells.

Coverage Area and Noise Level

All air purifiers have a certain coverage area. To pick a model that will be suitable for your place, it is important to know this number. In general, the bigger the coverage is, the larger the room will be purified. For smaller needs, you can choose a more portable option.

Another thing to consider is the noise level produced. This is important since many people place an air purifier in bedrooms, offices, and other quiet environments, where a loud rambling noise could become a problem. With that in mind, make sure the noise range of an air purifier you choose is within 15-30 dB, which amounts to the sound of falling leaves. Anything higher than that might get annoying, especially if run daily and for a prolonged time.

Control and Functionality

Last but not least, make sure to think about additional features a air purifier has. There's always more to them than it might seem at a glance. For example, many models come equipped with such features as timers, sound indicators to alert you to the need of replacing filters, sensors, and a power-saving fan used to slow down the operation of the device when the quality of the air in the room becomes better. As you can see the choices are numerous, and we hope after reading this guide finding an air purifier that will be right for you will be easy.
