8 Best Air Purifiers In 2020 (Based On Specs, Aesthetics)

Last Updated on

Who doesn’t have an air purifier nowadays? With the best air purifiers, you can filter out the dust parts, mold spores, even cigarette smoke. What sounded like science fiction 20 years ago is the new reality in 2020. And it’s easy.

The filter technology that is the essence of air purifiers. It’s no wonder that every other household in the US has one of these HVAC devices designed to clean air. Clean air doesn’t only protect your lungs; it’s designed to minimize the chances of mold or mildew development in your household.

As with every device, you’ll find both good air purifiers as well as bad air purifiers. When trying to find the best air purifier, you basically need to check 2 key characteristics:

  1. Filters. The nature, number, and quantity of filters that catch unwanted air particles are the core of every air filtration system. The advanced filters that all good air purifiers have are HEPA filters and carbon filters. Next-gen filters (equally good, if not better) include PECO filter and UV filters, for example.
  2. How much air can air purifier clean per hour? This is, in essence, the capacity of the air purifier. For big rooms, you will need a powerful +50W purifier. For smaller ones, even 30W purifiers could be enough. Every air purifier comes with ‘Purifiers room sizes of up to 100-700 sq ft’. Hidden behind this number are specifications like Airflow (measures in CFM), CADR (Clean Air Delivery Rate measured in CFM), ACH. In the end, however, it basically all comes down to power (wattage) and energy efficiency of air purifiers.

Other metrics to take into account when choosing the best air purifier are noise levels (should be below 60 dB), the number of fan speeds, and weight (chunky air purifiers can weight 20 lbs or more).

Based on these metrics, you can evaluate which air purifiers are not only good but brilliant. We’ve done just that.

Below you will find a list of the best air purifiers according to all these specifications, safe for one. That one – the one you have to evaluate for yourself – is the aesthetics.

All the air purifiers are beautiful as far as specifications are concerned. Everyone, however, does have his or her own taste. You should also have in mind the room where the air purifier you’re buying is going to be situated. Some people go for the classic look, some go for the avant-garde extravagance.

Based on your taste and the interior design consideration you should pick the most aesthetic purifier for your home:

#1 Alen BreatheSmart FLEX (Best Overall Air Purifier)

Of all the air purifiers, the Alen BreatheSmart FLEX is the best one to balance all the crucial specifications. It can clean a large 700 sq ft room two times per hour, and it can also clean air smaller 200 sq ft room seven times per hour.

When the turbo speed is engaged, the Alen BreatheSmart FLEX can clean your air of dust, allergens and prevent mold growth at 50 W of power. This creates a powerful 187 CFM airflow. At the same time, the best air purifier is gentle enough; you can set it on low speed and spend less than $0.5 per month running it.

The aesthetics are amazing. Below you can see how the ‘White’ model looks like. You can choose between ‘Oak’, ‘Rosewood’, ‘Electric Blue’, and several more color patterns. In effect, the Alen BreatheSmart FLEX becomes a piece of interior design:

Alen BreatheSmart FLEX is the best air purifier for small and large rooms
Alen BreatheSmart FLEX comes with a balanced harmony of specifications. Strong and gentle at the same time, with a top of the notch H13 HEPA filters.

The core of Alen BreatheSmart FLEX is the high-capacity H13 HEPA filter that can capture up to 99,95% of airborne particles bigger than 0.3 microns. That’s the best filtration system all the best air purifiers have.

Additionally, the upgraded version comes with an activated carbon filter (the filter itself weighs 0.66 lbs and is high-capacity) that can remove smoke, household chemicals, and volatile organic compounds.

One thing that sets the Alen BreatheSmart FLEX apart from all other air purifiers is a gentle sleep mode. This ‘lights out’ mode was validated by SleepScore to ensure both low luminosity and low decibel levels from the air purifier.

The whole device weighs 15 lbs; it’s easy to move around the house. You get the 4 fan speeds; the first 3 are very quiet (up to 49 dB) and can provide up to 147 CFM airflow. The last one – the Turbo speed – is powerful enough to achieve 187 CFM but can be a bit noisier (55 dB).

All in all, the Alen BreatheSmart FLEX presents a harmony of aesthetics and specifications. It is the most well-rounded and therefore the best air purifier you can buy:

Alen BreatheSmart FLEX (Upgraded)

Pros
  • Represents a harmony of specs you want in every air purifier
  • Can achieve high airflow of 187 CFM (powerful yet gentle enough)
  • Even if you put it into a giant 700 sq ft room, you can 2 ACH (air changes per hour)
  • Usually operates below 50 dB (only Turbo speed goes beyond 50 dB)
  • Modern aesthetics with 7+ natural colors to choose from
  • Comes with a top-of-the-line HEPA filter with the additional activated charcoal filter
Cons
  • Turbo speed can be noisy (55 dB)
  • It has a premium price

#2 Blueair Blue Pure 211+ (Minimalistic Swedish Design)

Even Swedes in Scandinavia have problems with air pollution. Pollen, mold, airborne bacteria, and pet odors are a part of most Swedish households. That’s why they developed the Blueair Blue Pure 211++ air purifier; with a touch of minimalistic Swedish design.

The best thing about a minimalistic design air purifier is that you can put it literally in every room without disturbing the interior design. The 61 W Blueair Blue Pure is powerful enough to purify the air in rooms up to 540 sq ft. You can easily put in a bathroom, living room, or pretty much any room that isn’t larger than 23×23.

Blueair Blue Pure has a 3-stage filtration system. The pre-filter made out of fabric is designed to trap larger airborne particles like hair and dust mites. The main filter – the particle filter – removes all the most annoying things air can carry. These include pollen, mold, allergens. For the finishing touch, you’ll find the carbon filter. This is the last stage in air purification; it removes smoke and odor-causing bacteria from the air.

Classic minimalistic Swedish design gives you a range of colorful options. You can see some of them here:

most colorful air purifiers designed by swedish hvac designers
Blueair Blue Pure 211++ is a series of Swedish air purifiers. They can purify the air in rooms up to 540 sq ft and come with a touch of Swedish minimalistic design.

They handle enough airflow to change air 5 times per hour in a small room. Blueair Blue Pure 211++ doesn’t have an airflow rate in the specification sheet; given the 61W maximum power and ACH=5, we can roughly estimate the airflow to be about 350 CFM.

At low speeds (the Blueair Blue Pure has 3 fan speed settings), it can be as quiet at 31 dB. You won’t hear the air purifiers. However, the high fan speed setting can reach a decibel level of 56. That can be quite annoying, especially if you’re running the air purifier in the bedroom during the night. Obviously, most people prefer to turn it to a low setting with a minimum of 31 dB noise levels.

All in all, the Blueair Blue Pure 211++ is quite a small but powerful air purifier. The Swedish design gives it that extra glare that many air purifiers lack.

Blueair Blue Pure 211++

Pros
  • Minimalistic Swedish design (perfect for maintaining interior design)
  • Can achieve high airflow of 211-350 CFM (estimated)
  • Can be used in larger bedrooms, kitchens or living rooms (with ACH up to 5)
  • You can choose to combine 2 colors
  • Very quiet on low setting (31 dB)
  • Quite an affordable price for this specs and especially for the appealing aesthetics
Cons
  • Can be louder on high speed setting (56 dB); you should switch to low speed at night
  • People tend to have problems choosing the right color

#3 Molekule Air (Most Revolutionary And Aesthetic Air Purifier)

If you’ve searched for the best air purifier a bit, you must have come across the Molekule Air. This is the most revolutionary air purifier that has been introduced in the last few years. In fact, it’s quite amazing what it can offer.

Let’s have a look at a few things that make Molekule Air such an amazing air purifier device (we’ll come to the next-gen PECO filter later on).

The first thing everybody is impressed by is the aesthetics. I mean, you can’t deny the Molekule Air doesn’t look amazing. That silver shine is actually machined aluminum. With such a modern design, the Molekule Air purifier can fit in every modern household.

Another advantage is seamless connectivity. Molekule Air is a smart air purifier that can connect to WiFi and you can control it via iPhone or Android app. Here’s how the smart Molekule Air – iPhone connection works:

Molekule Air is a revolutionary air purifier. It can be connected to WiFi, has an amazing design, and the next-gen PECO filtration system.

Do you see that leather strap? That’s not only visually appealing; it’s literally a handle by which you can lift the 18 lbs air purifier up and move it around the house. It can handle rooms up to 600 sq ft in size; after it purifies the air in the bedroom, you can easily lift it up and more it to the living room.

Now for the NASA level technology part; Molekule Air doesn’t have HEPA or activated charcoal filter. That’s old school air purification. The Molekule Air has integrated PECO filter; PECO stands for Photo Electrochemical Oxidation.

The revolutionary filter uses light to activate nanoparticles that cover the filter. In turn, the activated nanoparticles break down pollutants such as pollen, dust, mold, smoke, and so on on a molecular level. To power the PECO filter you need 85W of power. That makes the Molekule Air one of the most powerful air purifiers around. It’s cutting-edge science; using light to purify the air.

Of course, even the Molekule Air is not a perfect air purifier. It gets a bad rep because of the price. It looks expensive, it comes with new technology, and it is expensive. The Molekule Air can cost up to $800; only high-end and elite households can afford such a marvelous air purifier.

Molekule Air With PECO Filtration

Pros
  • Most revolutionary air purifier with NASA level technology
  • PECO filters; does a better job than several old-school HEPA filters
  • Immaculate design; made out of machined aluminum
  • You can move it from room to room easily; that’s why it has that leather strap
  • Seamless connectivity via WiFi and control via iPhone or Android app
Cons
  • Only one drawback: the price. Only high-end households can afford the Molekule Air

#4 Coway AP-1512HH (Best Price-Performance)

Most of the top air purifiers cost more than $300. They have good specs and, let’s be honest, sometimes overpriced aesthetic design. The Coway AP-1512HH is a perfect air purifier for everybody who needs a purifier that works really well (great specs) but doesn’t have that avant-garde look. That drives down the price of the Coway AP-1512HH to less than $300.

The specs are the strong selling point for the Coway AP-1512HH. It has quite a lot of power – 77 Watts, to be exact, powered by 120 V and 0.64 A maximum current. All this power can achieve an incredible 268 CFM airflow at one of the lowest high-speed fan noise levels of 53.8 dB.

The airflow is very important when it comes to air purification. CADR number you’ll find on the specification sheets (stands for Clean Air Delivery Rate) detonates the clean airflow for different pollutants. Coway AP-1512HH CADR for dust, for example, is 246 CFM. For pollen, it’s 240 CFM, and for smoke 233 Cubic Feet Per Meter (CFM).

Coway AP-1512HH has incredible specs; 268 CFM at a low noise rate of 53.8 dB. It’s one of the most powerful air purifiers with 77 Watts of energy.

Obviously, power is one part of the equation, and the filters are the other part. Coway AP-1512HH has 1 prefilter for larger dust parts (like hair) and 3 air purification filters. These include deodorization filter, True HEPA filter and, quite uniquely, the Vital Ion filter.

Combined they can achieve the high CADR rates for pollutants such as dust, mold, mildew, smoke, pollen, and so on.

All in all, the Coway AP-1512HH might not look avant-garde but it has the best specifications out of all the best air purifiers. And it’s available for less than $300.

It’s most appropriate for rooms up to 200 sq ft. For example, if you’re looking to purify the air in a small 12×12 room, the mini air purifier is exactly what would do the job very well without much overhead. The air purifier itself is quite strong; it has 60W of power and on the high fan speed setting (it has 3 settings), it will need 0.5 ampers to power.

The small and compact size comes from its 3-in-1 filtration system. Usually, air purifiers have 2 or 3 separate filters. In Pure Enrichment PureZone 3-in-1, three filters are merged into a tight singular unit. These 3 filters include the prefilter, activated carbon filter, and the well-known True HEPA filter. They are followed by a special 4th UV-C light filter. The UV adds another level to air sanitation; it targets the living microorganisms.

Its effective range is 129 sq ft. For most bedrooms, living rooms, or even kitchens, that’s not enough. However, if you have a small office or room, something in the range of 10×10, the LEVOIT LV-H132 does the job well enough.

As far as the filters are concerned, the LEVOIT LV-H132 is built quite in the same way as most of the bigger air purifiers. It has a pre-filter, followed by a carbon filter and a True HEPA filter. These three can deal with all kind of pollutants and unwanted smells in your office or small room:

There is nothing all that special about the Winix 5500-2 really (with the exclusion of the PlasmaWave filter, of course). Nonetheless, it is a solid air purifier available at a very affordable price range.

It features 4 filters; pre-filter, AOC carbon filter, True HEPA filter, and PlasmaWave filter. Two out of these are quite extraordinary. The AOC filter stands for Advanced Odor Control; this is a patented technology that used activated carbon granular in order to purify the air.
