Germ Guardian AC4825

Filters and Filtered Substances

The construction of this tower-shaped room air purifier GermGuardian AC4825 consists of three elements. To be specific, HEPA filter removes harmful impurities and different allergens from the air. Hence, it would be nice to give this air cleaner to asthmatic and allergic people as a present. Another part, Charcoal filter, eliminates specks and pet dander due to its porous structure. The third stage of air purification implies the usage of the ultraviolet light, which kills germs, various kinds of bacteria (including coliform bacteria) and other infectious microorganisms. As a result, the air is sterilized and consumers have a healthy microclimate in their dwellings.

Coverage Area and Noise Level

The GermGuardian AC4825 air purifier is recommended for use in small, closed rooms up to 167 sq. ft. Due to its portability and light weight, the device can be easily moved, located near one's desktop or in other parts of the apartment. If you run it at the highest speeds, it will create a so-called "white noise". In other words, this noise can be compatible with the background noise of human speech or falling rain. Moreover, if you run this device at a minimal speed, you will not even notice its noise.

Control and Functionality System

This air purifier is equipped with a mechanic control system and three speed settings. Consumers can run this air purifier at a low speed when they need constant and minimal air purification. If it's necessary to purify the air as fast as possible, it is better to switch to the highest speed. Consumers can also turn off the UV air processing and turn it on when needed. Furthermore, its built-in light indicator will alert you when the filter replacement is required. Finally, this air purifier is very similar to the famous UV Blue Air Purifier. Great!

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.

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.

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.
