What Are The Best Air Purifiers For 2018?

The best air purifier for 2018 might not be the same for everyone.

Keep in mind that different people have different needs in terms of air pollution. There is no magical air purifier that suits everybody’s needs.

Now that you’re aware of what an air purifier can do, let’s dive right into the reviews!

Best Budget Air Purifiers

Levoit Air Purifier

best air purifiersJust because you’re on a budget, that doesn’t mean that you don’t deserve to have fresh, clean air to breathe in your home or apartment.

That is exactly why we have a separate category for the best budget air purifiers!
Just because they’re cheaper, however, doesn’t mean that they’re not the best in their class. They may not have all the fancy features as some of the other ones on the list, but they still perform just as well.

This one from Levoit uses three stages of filtration:

  • A fine preliminary filter to neutralize bacteria, pet dander, and mold.
  • A true HEPA filter to capture dust mites, larger particles, and pollen
  • Then lastly an activated carbon filter that captures and neutralizes various odors.

This is the common sequence of filtration that you’ll come to find in most types of three-stage filtration systems.

This one also has a nightlight function, providing the right amount of light to guide you in the middle of the night. It’s also virtually silent – no need to worry about it keeping you up. There are also three different fan speed settings for whatever you’re feeling at the moment.

This purifier comes with a two-year warranty straight out of the box and Levoit also offers lifetime support, should you ever run into any technical issues.

top rated air purifierA couple of downsides:

  • It’s really only meant for smaller spaces and doesn’t do a good job in even medium-sized spaces.
  • You tend to have to replace the filter a little more often than usual.

These are really only two minor annoyances, but definitely, something to keep in mind.

All in all, for less than 100 USD (at the time of this article), Levoit offers you a great deal at a very fair price.

What We Loved

  • Nightlight function
  • Uses HEPA filter

What We Didn’t Like

  • Not great at larger spaces
  • Need to replace the filter often

GermGuardian AC4825

best air purifier 2018The first thing that you usually have to compromise on when having a budget is style.

So, if you didn’t love how the last one looked, we think we might have just the solution for you. If you prefer sleek, black models of your home appliances then look no further than the GermGuardian AC4825.

We talked about the three-stage filtration system with the last purifier. One amazing thing about this air purifier from GermGuardian is that it includes that same three-stage filtration system plus one other thing: A UV-C light.

What’s so great about a UV-C light? Well, it actually has the power to kill bacteria and viruses including, Rhinovirus E.Coli, and even streptococcus.

This is the perfect air purifier if you have a bunch of little kids or people in your house tend to get sick easily. This will help to keep those airborne germs out and the air fresh and clean for everyone in the house to enjoy.

air purifierOther nifty features include:

  • Nearly silent operation
  • Energy Star qualification so you know it won’t run up your energy bill or harm the environment
  • Odor reduction.

Also, when compared to the last unit, this GermGuardian works much better in larger rooms. It still probably isn’t best for large houses or abnormally large apartments, but it will definitely get the job done in just about any medium-sized home office or living room.

GermGuardian does offer support for this product but it’s been reported that their customer service isn’t necessarily the best.

While you never intend for anything to go wrong, you just never know and it’s nice to have the support of the company. If that doesn’t bother you, then we definitely think this is a sleek budget alternative that will look great in any home.

What We Loved

  • Extra UVC light filtration
  • Fights against viruses
  • Great for odor

What We Didn’t Like

  • Not great customer service

PureZone 3-in-1

best air purifier for smokeEvery single one of the air purifiers in the ‘Best Budget Air Purifiers’ section has one thing in common. Care to know?

They’re each under 100 USD at the time that we published this article! That’s three amazing options for you to get an air purifier and get any room on track to having clean, fresh air. This is our last budget option and it comes from PureZone.

PureZone is a trusted brand when it comes to air purifiers. They might not be as famous as Dyson, but if you’ve done any research into air purifiers whatsoever, then you have most likely heard of PureZone.

air purifier 2018Alright – now for the product features.

Like the previous two purifiers, this also features a three-stage filtration system. It also features the UV-C light sanitation to offer a deeper level of clean by safely eliminating germs, viruses, and bacteria. This is a great option for use in a classroom.

There’s also a three-speed fan, an automatic timer to have the purifier shut off after two, four, six, or eight hours of continuous use, and also, a filter reset indicator! This is a tiny feature that may not seem like a big deal but can prove to be very helpful in making sure you replace the filter on time.

In turn, this will ensure you always have the cleanest air and will make the life of your air purifier last for as long as possible. This might not be the most beautiful air purifier in the world, but it gets the job done. Another thing to note is that this does dry out the air a bit.

It definitely purifies the air but if the dry air in your place is an issue, then you might want to consider a different air purifier.

What We Loved

  • Filter reset indicator
  • Automatic timer
  • Trusted brand

What We Didn’t Like

  • Dries out the air a little bit

Excellent Mid-Range Air Purifiers

Coway AP-1512HH

Alright alright, time to step it up. We offered three different budget air purifiers but now it’s time to talk about some excellent mid-range air purifiers. The ones in this category tend to offer a few things over the previous category: Better design, longer-lasting performance, larger room coverage, and filters that you don’t have to change as often!

These are all things that you, of course, can expect as you move up in price. We’ll see all of those categories truly maxed out in the high-end category but for now:

Let’s take a look at the best mid-range air purifiers.

best air purifiers 2018Firstly, this air purifier from Coway features two sleek colors: Black and gray, and white and gold.

Either way – you can’t go wrong. On this purifier, you’ll find not only a filter change indicator but also an air quality indicator to actually let you know how well it’s working.

There’s an ionizer mode for maximum performance but also an eco-mode for more just room maintenance. Also, out of all the purifiers on the list (so far), you’ll get the most square footage out of this guy.

How much? Up to 528 square feet! That may not sound like much but when compared to 200 square feet (the last air purifier on our list), that’s about 2.5x the coverage! Really not bad.

This also features an automatic mode that will automatically adjust the fan speed depending on air quality. Is air good for now? It will automatically adjust down – ultimately saving you money and wear-and-tear on your product.

Some downsides:

  • It is much bigger than a lot of purifiers out there which can make it difficult to place.
  • It is also not the quietest air purifier on the market.
  • With that being said – it works fabulously and will truly clean up the air in any room without any trouble.

What We Loved

  • Eco mode
  • Good room coverage

What We Didn’t Like

  • Bulky design
  • Not super quiet

Honeywell True HEPA Allergen Remover

top rated air purifiersIf you are one of those people who need a name brand to feel comfortable with a purchase, then consider this air purifier from Honeywell. Honeywell has been in the game of fans and air purifiers for a very long time now.

You can trust them.

And this True HEPA Allergen Remover is absolutely no exception. Just as a gauge, this works best in rooms up to 465 square feet. One of the best parts?

This air purifier actually circulates all the air in the room up to five times per hour! That’s insane to us. That means every air particle in your room will go through this filter five times per hour.

Now that’s some clean air.

This air purifier works great for pet dander, dust, pollen, and even smoke. This purifier from Honeywell might be the best air purifier for smoke. It doesn’t only purify the air but actually works to get rid of the odor left behind by these things as well.

top rated air purifier 2018One thing to note, however:

When you start getting into the more expensive air purifiers, the filters start being more expensive. This is especially true of the Honeywell True HEPA Allergen Remover. However, with that being said – this is an extremely powerful purifier and while it’s only recommended for rooms up to 465 square feet, it’s often been reported to work in rooms up to 1000 square feet.

One other downside is that the purifier itself can be extremely loud, depending on the setting.

On low or medium settings, it sounds like a normal fan. However, on high or turbo settings and you might have a bit of difficulty holding a conversation in the same room!

If you can get past the noise and expensive replacement filters, then we think you’ll love this air purifier from Honeywell.

What We Loved

  • Fast circulation time
  • Good for smoke

What We Didn’t Like

  • Expensive replacement filters
  • Can be very loud

Winix 5500-2 Air Purifier

top rated air purifiers 2018Perhaps you don’t necessarily need an air purifier that’s super powerful. Maybe you have a small home office or a kid’s bedroom that you want a small purifier for. This is the perfect mid-range option for people who don’t want or need to pay for all the extra bells and whistles. Don’t get us wrong: This still has all the features that you’ll want from an air purifier.


  • Smart sensors that automatically adjust the strength of the purifier depending on air quality
  • Three-stage air purification
  • PlasmaWave Technology to eliminate odors at a molecular level
  • Four fan speeds
  • LED auto dim feature so you won’t be blinded at night
  • And even a filter replacement indicator!

top rated air purifiersWinix has thought of everything in terms of features – especially at such a decent price. The filters are also stupidly easy to change in this and you’ll only need to do so every six months.


The cord that comes with it is super short. You’ll need to purchase an extension cord if you want true flexibility. Also, the remote that comes with it doesn’t work perfectly. It actually appears to be cheaply made and some of the buttons can be a bit finicky.

All in all, this is a decent air purifier and is particularly good if you have any sort of pet allergies. Seriously. It might be the best air purifier for pets or just the best air purifier for allergies in general. You could be allergic to cat or dog dander, have this air purifier in a room, and not have to worry about your allergies whatsoever.

This thing is that good. Every air purifier is going to have some downsides but if you can get past them for this one, you will be highly rewarded with fresh, breathable, clean air.

What We Loved

  • Good for small offices
  • Gets rid of all dander, perfect for allergies
  • Easy to change the filter

What We Didn’t Like

  • Remote feels a bit cheap

Top High-End Air Purifiers

Rabbit Air MinusA2

best air purifier 2018Alright, time for another category switch!
This time: We are in the ‘Top High-End Air Purifiers’ category.

You’re going to notice a few key changes now that we’re in the high-end category:

  • Huge jump in design aesthetic
  • Much more average room coverage for each purifier
  • And generally much more quiet operation

A few other key changes you’ll probably notice:

  • These are much larger air purifiers
  • The filters for each of them are going to be that much more expensive to replace

But hey – it’ll be up to you to figure out whether or not the price is worth it.

air purifiers 2018With this air purifier from Rabbit Air you’ll get room coverage up to 815 square feet, five-year warranty and 24/7 customer support from Rabbit, and a six-stage filtration system!

That’s right – while a lot of other air purifiers only have three stages, this one has six.
Pet allergies, odors, dander, dust, toxins – anything really, will not stand a chance against this purifier from Rabbit Air.

It’s also super stylish and can easily be mounted on the wall so you don’t have to sacrifice style for function. They even have an artist series where you can choose certain designs to go on the front if you so desire.

This unit isn’t as quiet as we’d like it to be for such a high-end purifier, but we think the design alone is enough to make it worth the purchase.
If you want a sleek, user-friendly, effective air purifier – then you have come to the right place.

It’s not the most powerful high-end one out there but it is definitely one of the best-looking.
If you suffer from intense allergies or just want something with extreme power, then you might want to hold out and purchase a different purifier.

What We Loved

  • Beautiful design
  • Can be mounted on the wall
  • Five-year warranty

What We Didn’t Like

  • Not as rugged as others out there

dyson air purifierWe don’t think we could possibly include a list of the best air purifiers without including one from Dyson.

Dyson has proven itself to be an industry leader in all things fans or suction. They have not only a line of beautiful products, but a line of beautifully-engineered products. Aside from how beautiful the Pure Hot Cool Link from Dyson looks, it actually functions as a great product.

It’s an air purifier when you need it, a cooling fan in the summer months, and a pretty efficient heater in the winter months! Not only will it heat and cool you, but it will do so with purified air.

Where else can you get cool (or hot!) clean air blown, throughout your house?

dyson air purifiersAs we could expect from Dyson, this air purifier is also Wi-Fi enabled. You can actually control your air purifier and see all of the statistics about your room from an app!
It is continuously monitoring and reacting to the air quality in your room.

The lower it is, the more it works. But once it gets the quality up to an acceptable level, it’ll slow down this saves you both electricity and filters.

It also features automatic nighttime mode and voice control. This is truly an intelligent air purifier for the year 2018.
Note however that this isn’t necessarily the best machine for a standalone fan or heater.

What it excels at is this:

  • Delivering purified cool air and purified warm air
  • It won’t necessarily cool or heat large rooms or particularly quick, but it will do so with fresh clean air
  • As long as you don’t have any unrealistic expectations in regard to the heating and cooling aspect

We easily think that this Dyson Pure Hot Cool Link Air Purifier is a beautiful machine that is well worth its price.

Are you interested in Dyson air purifiers?

We also wrote a review about the Dyson Pure Cool Link that you can read about here.

What We Loved

  • Amazing design
  • Can control and track stats with an app
  • Automated fan speed to save electricity
  • Dispenses cold and hot purified air

What We Didn’t Like

  • Extremely expensive
  • Takes a while to cool or heat the room

This BreatheSmart FLEX from Alen might just offer you the best solution for that. You can place this in literally any room and it will immediately improve the look in the room.

You can put it on the floor or if you’re a bit handier, you can mount it on the wall for a sleek look. And we guarantee that you’ll be able to find a color that you like.

  • HEPA-OdorCell which remains powerful odors in the air.

We are absolutely in love with the Alen BreatheSmart FLEX, we barely have any negatives to say about it! It is a bit loud but not too much louder than a boxed fan and actually sounds nice for white noise while you sleep. Alen is also known for their exceptional customer service.

In fact, with each new purchase, you can get a free phone consultation with their team to help you determine the best way for you to use your new air purifier. This is definitely in the running for the best air purifier 2018.

Perfect Air Purifier for Large Spaces


best air purifier for dustAre you looking to purify an extremely large area?

Think maybe a warehouse, an open office, or maybe you just have a giant house.
If you couldn’t tell from the name, the AIRMEGA 400S might just be the air purifier for you.

While a lot of the other air purifiers really only have max coverage for up to 800 or 900 square feet,
The AIRMEGA 400S has coverage for up to 1,560 square feet!

There’s also an app you can download for either iOS or Android that will give you a ton of information:

  • Speed control
  • Indoor air quality report
  • Scheduler
  • Filter lifetime monitor

hepa air purifierIt also includes a smart mode that automatically adjusts the fan speed as the air quality gets better or worse. This is essential if using an air purifier for a large room because they use a lot of energy. Even if it shuts off for an hour per day, that can really add up in terms of energy savings.

While this is more of a heavy-duty air purifier and definitely takes up a lot of room, it still looks sleek, stylish, and expensive.
It comes in either white or a really nice graphite color that will blend in any room.

This is significantly more expensive than any others on our list (close to 1000 USD at the time of this article), so if you don’t need it specifically to purify a large space – we recommend getting something smaller. AIRMEGA really has provided the best solution for purifying large spaces.

What We Loved

  • Perfect for huge spaces
  • Can control via the app
  • Two color options

What We Didn’t Like

  • Extremely expensive

Buyer’s Guide

We know.
There are what seems like endless options when it comes to air purifiers.

It can seem confusing and it can be overwhelming. And it can seriously be exhausting trying to figure out which one is the best! Of course, which one you purchase is going to completely depend on your exact needs.

With that being said, we still think there are a few essential things when it comes to air purifiers that you can use to guide your purchasing process.

HEPA Filter

Is this filter a HEPA filter?

They’re essentially industry standard at this point when it comes to air purifiers. HEPA stands for high-efficiency particulate air and they’re extremely efficient. They’re the best at removing odor and truly trapping dust particles to ensure consistently clean air.

Auto Mode

This is an important feature to us, especially for larger air purifiers.

What this does will automatically adjust the fan speed to the air quality in the room.

Like we’ve mentioned before:
If the air quality is good, the fan speed will go down. The air quality drops, then it will automatically kick back up until the room is completely clean.hepa air purifiers


This isn’t essential but it is nice to have.
Can you set it to turn off partway through the night or a few hours after you leave? It’s not great to leave it on all night, so it can be nice to have one that has an automatic timer.

best air purifier for pets


Of course, one of the main things you should be looking out for is coverage!
How much actual square footage does it cover?

The maximum is always just that – the maximum. You can actually use it in smaller rooms for more efficiency. If you use a large capacity air purifier in a small room, it will simply circulate the air that many more times per hour providing you with cleaner air.
This can be a good option if you suffer from allergies.


Alright, so with so many great options – which one is the best air purifier?

We’ve had everything from budget air purifiers to high-end but each has been in the running!
We’re looking for which one offers the best performance, most features, best design, and most overall value when compared to the price.

Which air purifier did we choose? For us, the answer was clear.

We had to go with the Alen Breathesmart FLEX. It combined the best of aesthetics but also functionality.
It comes in a ton of different colors, offers great coverage, isn’t too loud, is energy efficient, and even comes with a lifetime warranty.

For us, it was clear.
Yes, they are a bit more expensive we can’t deny that, but they provide a lot of value for what you’re buying. You’re spending a lot, but you’re getting a lot. This is a very high-quality machine that will serve you for years to come.


What Should I Look For In An Air Purifier?

First of all, you should think about which air purifier that will fulfill your needs. Every air purifier is not completely the same and does not do the same so in short, they work differently. Because of that, we recommend that you examine what you want to remove.

Is it the smell of cigarette smoke, fungus or maybe it is for reasons that will cause an allergic reaction like pollen, fur, and dust particles. Air purifiers also come in different sizes so you should also consider how big it is or maybe how effective the air purifier is for different room sizes.

How Much Room Will An Air Purifier Cover?

best air purifier for moldAir purifiers cover different room sizes depending on the size and capability of the air purifier. To measure which air purifier suits your needs we need to learn more about some of the terminology used when talking about the specifications of air purifiers.

CADR or Clean Air Delivery Rate; CADR indicates the volume of filtered air delivered by the air purifier. A larger number of CADR means that the air purifier filters a larger amount of air fast.

ACH or Air Changes per Hour; Indicates how frequently the air purifier filters or changes the air in a given amount of space per hour. 1-2 air changes per hour will result in air that is clean, but not as clean as it could be. For Allergy relief, we recommend a minimum of ACH of 4.

CFM or Cubic Feet per Minute; This number basically means how many cubic feet of air is going through the air purifier per minute. This number is a crucial decider when choosing an air purifier as a higher CFM provides with better air purification results.

How Long Should I Run My Air Purifier?

For best results, it is recommended to continuously run your air purifier at all times. While this may decrease the lifespan of the filters it certainly pays off in terms of healthy and clean air. Some high-end air purifiers detect the air quality in your home and turn on automatically if the air is polluted.

Do I Have To Spend A Lot of Money To Get A Good Air Purifier?

It really depends on where you want to use your air purifier to run, if you want to purify the air in a larger area you must consider buying a bigger and more powerful air purifier and that will, of course, cost you more. Paying for a High-end or top-of-the-line air purifier may also have extra features or a neater design to it also you should consider the noise level some purifiers may have.

If you want an air purifier to run at night in your bedroom you should probably consider a smaller air purifier that is effective and silent. So, in conclusion, pay for the air purifier that suits your needs, a more expensive air purifier might not always be YOUR best solution.

All This Air Purifier Nonsense Has Me Even More Confused

Well, technically that is not even a question… But fear not! We have for you, the consumers, fault assembled an easy to read buyers guide that will guide you through a variety of air purifiers, whether it being the best high-end purifiers, the best budget air purifiers, or somewhere in between.

Didn’t Find What You Looked After?

We have written about many different air purifiers for example: Filterless Air Purifiers, Air Purifiers for allergies and Air Purifiers for smoke. Just to name a few
