Coway AP-1512HH Mighty – Best Air Purifier 2018

coway ap-1512hh mighty best overall air purifierIf you are searching for an air purifier that will excel in all situations, then look no further; the Coway Mighty AP-1512HH is that air purifier. Aside from the technical aspects, which I will expand on further down, the Coway Mighty is actually a nice looking, modern air purifier that will slot into any room design with ease.

4-Stage Filtration System that Catches Everything

I think the key difference between the Coway and lesser performing air purifiers is the 4-stage filtration system.

There is a pre-filter, which I presume is there to make the other filters last longer. Then there is an activated carbon filter, which is essential for eliminating odors from pets and smoke, making the Coway one of the best air purifiers for pets. The True HEPA filter captures everything else that the other filters missed, and by this stage, your air will be 99.97% cleaner than it was. There is also an ionizer for eliminating any pollutants in the air.

Eco Mode and Air Quality Indicator

coway ap-1512hh air quality indicatorThe first thing you will notice when you switch on the machine, no matter how clean you think your home is, is the air quality indicator. It will flash a few different colors while the particle sensing technology examines the air, and then it will change to a constant red. This red light indicates that you have bad air quality.

The impressive thing is, after running the Coway Mighty on full power for 10-20 minutes, the air quality indicator should turn to blue. The blue light indicates that your air quality is good.

It’s up to you how to proceed after this; unless you live in a very smoky or polluted environment keeping the machine on full power might be overkill. You can keep the machine running on low power, which produces a barely audible 24.4 decibels. The highest power setting produces 53.8 decibels, which I find to be a pleasant background hum.

There is also the Eco mode, where if the air quality has been good for a period of 30 minutes the purifier will automatically shut down to save energy consumption. When the air quality is reduced, the purifier will switch itself back on again. I prefer the auto mode setting, where the air purifier constantly runs on the lowest setting. When it detects a reduction in air quality it will switch to a higher setting until the air quality is good, and the switch back to the lower setting.

Best Looking Air Purifier of the Year

coway ap-1512hh mighty comes in black or whiteI was slightly taken aback on first glance; I was expecting the unit to be smaller than it is. However, when you factor in the number of filters it contains and the way it completely cleans the air, the size becomes a non-issue.

The fact that it only weighs around 15lbs means it can easily be moved to wherever in the home it is needed. I like the fact that if I am cooking I can just take the Coway with me into the kitchen, run it on the low setting while I am cooking, and it eliminates all cooking smells. For the occasional smoke and burning smell, I can switch it to full power and it will take care of it all.

Conclusion

All of the air purifiers on this page are good at something, be it smoke, allergies, or dust. The Coway Mighty AP-1512HH is good at everything, and that makes it the best air purifier on the market in 2018.

The fact that this purifier is half or even quarter of the price of the high-end air purifiers just seals the deal for me. I can have one of these working in my bedroom and another one in my living room, for the same price as a higher priced air purifier that won’t do as good a job as cleaning the air.

If you suffer from allergies or just want clean air, then buy the Coway Mighty air purifier. You will not be disappointed.

 


How to Choose the Best Air Purifier

When you are in the market for a new air purification system, there are several things you need to look for. Although all air purifiers are designed to clean the air, there are some models that have more features, bigger filters, or quieter operation.

This page has been created for the purpose of helping you to find the best air purifier for your needs. Everyone has different needs, and you want an air purifier that will work for you.

Different Types of Filters

One of the most important factors to think about when looking at air purifiers are the filters it contains. There are a variety of different filters, with each one performing a different task when it comes to cleaning the air.

HEPA Filter

air filters for air purifiersAll purifiers contain a HEPA filter, which stands for High-Efficiency Particulate Air. You have to be careful here, some manufacturers will claim their filter is ‘HEPA-like’ or ‘HEPA-style’, but they won’t pass the strict guidelines that are required to be classed as a HEPA filter. To be classed as a HEPA filter by the United States Department of Energy, it must remove at least 99.97% of all particles 0.3 micrometers in diameter.

To ensure you are confident you are purchasing a HEPA filter, air purifier vendors have started marketing them as ‘True-HEPA’. This just means that the filters have passed the requirements to be classed as a HEPA filter. If you are in any doubt, just know that HEPA air purifiers perform best at removing the smallest of particles from the air.

IQAir has developed a filter called ‘HyperHEPA’, so as well as passing the criteria to be classed as HEPA, it also removes 99.5% of all particles at 0.003 micrometers in size.

Pre Filter

Most air purifiers’ ship with a pre-filter. The main job of the pre-filter is to capture bigger particles such as pet hair, dust, and pollen from the air before they reach the more expensive HEPA filter, thus prolonging the life of it. The more clogged an air filter becomes the less effective it is at removing contaminants from the air, so the pre-filter is an important stage for the air to filter through.

One of the benefits of a pre-filter, apart from being relatively inexpensive, is that most of them can be washed and re-used. This will greatly reduce your costs when running an air purifier, and because the pre-filter captures bigger particles it will need cleaned more often.

Activated Carbon Filter

An activated carbon filter is made from charcoal that has been treated with oxygen. The special manufacturing process opens up millions of tiny pores in-between the carbon atoms. This results in highly-porous charcoal, and allows odors and gasses to be absorbed easily.

If you need to get rid of a smelly dog odor, or perhaps you cook a lot and want to remove the smells, then an air purifier with an activated carbon filter is essential.

Odors and other gasses are chemically bonded to the surface of the charcoal, and when all of the bonding points of the surface are full the filter will be ineffective and will need to be replaced.


IQAir HealthPro Plus – Best Air Purifier for Allergies

iqair healthpro plus best air purifier for allergiesThere is a reason the IQAir HealthPro Plus has been rated the number 1 air purifier for allergies from multiple sources: it just works. Yes, it is more expensive than other air purifiers. Yes, it may seem bigger and bulkier than other air purifiers. But the fact is when you wake up in the morning and your allergies have gone none of that will matter.

HyperHEPA Filtration Captures Every Type of Allergen

IQAir’s patented HyperHEPA filtration technology is the main reason this air purifier is the best in class for allergy prevention. This special filter captures ultrafine particles down to a size of 0.003 microns in size. To put that into context, particles in a virus are 10 times bigger than that, and standard HEPA filters only capture particles 100 times that size.

Because the HyperHEPA filter is the last stage in the filtration process, by the time the air reaches this filter only ultrafine particles are left. The first filter, the Pre-Max pre-filter, eliminates all the allergy-causing microparticles; pet dander, pollen, and mold spores.

Next, the air passes through the V5-Cell, which is an activated carbon filter that eliminates odors and harmful chemicals, before passing through the HyperHEPA filter. The clean air is then dispensed into the room at 320 degrees, so no matter where the HealthPro Plus is situated you can be sure you are breathing in clean air.

32% Less Noise Even on Highest Setting

iqair healthpro plus air quality indicatorOne of the major gripes most people have with air purifiers is the fact that to get the best performance, they have to be run on the highest setting. Now, the highest setting will mean the fan is running full speed, which produces a lot of noise. People generally can’t sleep with a noisy fan running so they are forced to turn it down at bedtime, which means they don’t feel the full benefit in the morning.

The IQAir has an average of 32% less noise than previous models, and that’s on every fan speed, not just the lowest. Even when running on full power you can have this air purifier in your bedroom without being disturbed. If you need complete silence you may need to turn it down a notch or two, but generally, this is quiet enough that most people can comfortably sleep with it running in the bedroom.

Energy Efficient with a Longer Filter Life

iqair hyper hepa filter lasts longerThe IQAir HealthPro Plus is a big and powerful machine, so I was a little surprised when I read that it is energy efficient. Usually, more power means more energy usage. The New Edition fan has been built with state-of-the-art aerodynamics and is contained in a housing that has eight shock absorbers to further reduce noise.

This air purifier requires the same amount of energy as a conventional light bulb, which is simply amazing considering it has the most powerful fan ever used in a home air purifier. At the highest speed setting, it requires 215 watts of power, while on the lowest setting on 27 watts is required. This means that you can keep the IQAir running all day for literal pennies.

The New Edition filters have been designed to last 38% longer, and they are fairly pricey to replace so this will also save a lot of money in the long run.

Conclusion

If you suffer from any type of allergy, you can be sure that the IQAir HealthPro Plus will give you the relief you have been searching for. One user even claimed that his allergies were gone for the first time in 30 years thanks to this machine. Designed for allergy sufferers, energy efficient, and very quiet; the IQAir will not let you down.

 


Rabbit Air MinusA2 – Best Air Purifier for Smoke Removal

rabbit air minusa2 best air purifier for smokeWhen it comes to smoke removal, the Rabbit Air MinusA2 air purifier is very effective. It will also blend into any room thanks to its stylish and customizable looks, and it’s so quiet you won’t even hear it on the lowest setting.

Whether you need an air purifier for smoke from cigarettes or cigars, internal smoke from a feature fire or log burner, or even outside smoke from bonfires or forest fires, the MinusA2 is one of the most effective air purifiers on the market at removing smoke and odors.

6-Stage Purification Including Activated Carbon and Odor Remover

What makes this air purifier so effective at dealing with smoke is the 6-stage purification system. The pre-filter and the medium filter are the first filters that the air passes through, and they catch all particles down to 1 micron in size. Things like dust, pollen, and pet dander will get captured here before the air gets passed through the HEPA filter.
The HEPA filter captures 99.97% of particles down to 0.3 microns in size. These particles are not visible to the naked eye and can be mold, bacteria, or other particles that carry viruses.

rabbit air minusa2 filtration system activated carbonThe next filter actually comes down to the customer; there is a choice of four different filters depending on what you want the Rabbit Air for. There is a Germ Defence filter, a Pet Allergy filter, a Toxin Absorber filter, and an Odor Remover filter. Since we are reviewing the Rabbit Air MinusA2s ability to deal with smoke, the Odor Remover filter is the preferred choice here.

After the air has passed through all of those filters, if there is anything left that is not pure air then the last filter, the charcoal-based activated carbon filter will remove it. This filter, along with the Odor Remover filter, is the primary reason why the Rabbit Air is so effective at removing smoke and odors.

Negative Reviews – Did They Buy The Correct Filter?

rabbit air minus in blackThere are a few reviews on Amazon that state this air purifier does not completely remove smoke and the smell of smoke from the air. Now, I would like to know what filter these reviewers ordered with their air purifier.

As I mentioned above, there is a choice of four filters that can be shipped with your Rabbit Air MinusA2. I can’t stress this enough, if you are buying this air purifier for its smoke removing capabilities then you must order the Odor Remover filter. If you order any of the other filters then it may not be as effective at removing the smoke smell.

Conclusion

With its stylish appearance and the ability to be free-standing or wall-mounted, the Rabbit Air MinusA2 won’t look out of place in any smoky environment. The ultra-quiet operation – only 20 decibels on the lowest setting – and effective filtration system enable this air purifier to be left on at all times without disturbing the owner.
If you are looking for an air purifier to deal with a smoke-filled environment, then the Rabbit Air MinusA2 is as effective as you can get.

 


Alen BreatheSmart – Best Air Purifier for Dust

alen breathesmart best air purifier for dustIf you suffer from an allergy to dust or you just want a dust-free environment, the Alen BreatheSmart air purifier could be the one for you. The high CADR rating of this purifier combined with the powerful features will ensure that a room up to 1100 square feet will have completely clean air in only 2 hours.

SmartSensor and WhisperMax Technologies

The BreatheSmart features Alen’s exclusive SmartSensor feature which automatically detects and adjusts to changing air quality, prolonging filter life and conserving energy.

If you set your air purifier to auto, then it will use the air quality indicator to determine the power setting to use. The air quality indicator has three different colors, depending on the quality of your air. A blue indicator means your air quality is good, and the BreatheSmart will switch to the lowest possible setting, while still maintaining a good quality of air.

A pink indicator means that there are moderate pollutants in the air, and Alen will switch the setting up a notch until it is clear. If the indicator is red, then there are heavy contaminants in the air and the air cleaner will go on full power until good clean air is restored.

The WhisperMax technology has been designed to keep the noise to a minimum when you are purifying your air. On the lowest setting, the Alen BreatheSmart will output a whisper of 41 decibels, which is ideal for a bedroom or nursery. The highest setting is 56 decibels which is quite a bit louder, but you shouldn’t need to use this setting much unless you live in a heavily polluted area.

This air purifier gives off a nice gentle hum, compared to other purifiers that emit high pitched whining noises.

Customizable and Child-Friendly

alen-breathesmart-customizable-coverThe Alen BreatheSmart is fully customizable to ensure it fits in with any décor. There is a wide range of interchangeable covers, and also different filter types depending on what you need it for most.

The standard HEPA-Pure filter should be enough for most needs, however, if you live in a dusty environment you may want to upgrade to the HEPA-Silver filter. You could always change your mind after you purchase as the filters are easily changed.

The Alen BreatheSmart air purifier has been built with families in mind. There is a lights-off mode which is designed to be used at bedtime, where the lights will turn off and the machine will switch to the quietest setting. There are also a couple of child-friendly features include a locking control panel and child-safe vent guard, so if your little ones decide to investigate they won’t come to any harm.

Final Thoughts

If you suffer from allergies and are not quite sure what they are, then the Alen BreatheSmart will offer you relief. It is ideal for allergies to dust mites, which are commonly found in house dust. However, it is not a one-trick pony, and the Alen will also offer you relief from pet dander allergies, hay fever and can even help with asthma symptoms.

Of course, you may not suffer from any allergies, and just want to breathe uncontaminated air. In that case, the Alen BreatheSmart will gladly assist you in your pursuit of clean air.

 


What Does an Air Purifier Do and How Does it Clean the Air?

used for removing pollutants and contaminantsAn air purifier’s main job is to remove contaminants and pollutants from the air. These contaminants are made up of tiny particles, most of which cannot be seen by the human eye. These particles can be dust, pollen, pet dander, mold, smoke, viruses, bacteria, and even odors.

Most of the time, it will be the indoor air that is cleaned. The Environmental Protection Agency states that indoor pollutant levels are two – five times higher than outdoor pollutant levels, and in some cases, they are 100 times higher! The fact that most people spend almost 90% of their time indoors explains why the use of air purification systems is increasing all the time.

In most air purifiers, the air in the room circulates through the filtration system, which usually consists of one or more very fine filters. These filters collect the particles from the air that passes through them and as a result, clean air is released back into the room.

The more filters that an air purifier contains, usually means it will be better at catching more particles.

What Filters Does an Air Purifier Contain?

air purifier filtersMost of the best-rated air purifiers will contain a High-Efficiency Particulate Air Filter, which most of us know as a HEPA filter. HEPA filters are designed to catch 99.97% of all particles all the way down to 0.3 microns in size. These are the type of particles that are not visible to the naked eye, but cause problems with allergies and can contain viruses and bacteria.

Most air purifiers will contain a pre-filter that will be the first filter the air passes through. The job of the pre-filter is to catch larger particles before they reach the HEPA filter, such as pet dander, pollen, and dust. This ensures that the HEPA filter can do its job more efficiently, and will also prolong the life of it.

A charcoal based activated carbon filter may be included, and the job of this filter is to eliminate smoke particles and odors. Other filters are usually specific for the job they are designed to do, such as an odor remover filter or a toxin remover filter.

The size of the particles the purifier can remove play an important role in just how safe your air is to breathe.

The smaller the particle is, the more potentially hazardous it can be for your body, despite how counter-intuitive that seems! This is because if the particle is small enough, it can pass through the membranes of cells inside your body and cause untold damages.

You will want to keep your eyes peeled for air purifiers that can remove the smallest possible particles, especially if you or a family member suffers from allergies from pets, dust, pollen or any other allergen.

 

Other Common Allergies an Air Purifier Can Help With

pollen allergies are more common in the summerPet dander, pollen, and dust are the three most common allergens that cause allergic reactions. These particles are so small and light, that even walking across the floor will disturb them and throw them up into the air.

This is the reason that vacuuming alone will not help with allergies; the vibrations and movement from the vacuum cleaner cause the tiny particles to be displaced from the floor and into the air.

An air purifier will then suck the particles into the filters, and then blow out clean air. A combination of a decent vacuum cleaner with a HEPA filter and an air purifier is one of the best ways to deal with allergies.

Extra Features

There are a few extra features that you may want to look out for:

Filter Replacement Indicator

Most apart from the most basic of purifiers will have this feature. It tells you when a filter needs replaced, which is good because an air purifier will not perform properly if its filters are clogged.

Air Quality Indicator/Sensor

An air quality indicator allows you to see the quality of your air. If the air quality is bad you can put the machine on the highest setting until it is good, and then turn it back to a lower setting. An air quality sensor will do this for you automatically.

Timer

This is a handy feature if you are out all day and don’t want the purifier running constantly. You can just set the timer to turn the purifier on an hour or two before you arrive and you will be greeted with clean air.

Night Mode

Some air purifiers contain a night mode, where a lower setting and dimmer lights are used.

What is a CADR Rating?

CADR stands for Clean Air Delivery Rate and is a measure of how well an air purifier will work against certain particles. It’s a measure of how much clean air will be distributed into a room, so if a purifier has a CADR of 190, it means it will pump out enough clean air to fill 190 cubic feet per minute.

CADR is measured against the effectiveness of removing 3 types of particles; smoke, dust, and pollen. So depending on what you need the air purifier for you can see how effective it is at removing certain contaminants.
