Blueair Classic 605 is the first with a three-dimensional air interaction (from the bottom and two sides). To clarify, the Blueair Classic 605 has one air input and one air output grill on each side of the air purifier.

As a result, any polluted air inhaled from any direction will be released fresh from the same direction.

With the charisma of a seasoned CEO, the Classic 605 commands attention. It’s not about being ostentatious; it’s about setting industry benchmarks. 

Weighing at a substantial 35 lbs, it might seem like a heavy stock, but its dividends in fresh air might just be worth the weight. brand’s other families. So if you opt for a lower-budget air purifier with the same design, it is unfortunate that you can’t find one.

In addition, from the top and bottom of this Blueair Classic 605 are the air output and input, respectively. This unrivaled design optimizes the airflow and makes the purifier the most efficient among its rivals.


A statement we’ve all heard too often in the world of high-range air purifiers: “Blueair Classic 605 is a powerhouse.” What drives this machine? Let’s unpack this.

  • Particle Filter: A marvel that ensnares a whopping 99.97% of unwelcome guests. From the benign pollen to the menacing bacteria, nothing escapes its grasp if they’re between 0.1 to 10 microns in size.

  • DualProtection Filter: Think of this as the advanced cousin, a sublime merger of the True HEPA filter and the Activated Carbon Filter.

The Blueair Classic 605’s DualProtection filter is one of the highest-quality air filters on the market, being 100% recyclable establishing its ground in removing the carbon footprint.

With lots of fan power, the Blueair Classic 605 is the clear winner, having the highest efficiency of trapping 99.97% all particles as small as 0.3 microns in the air.

The IQAir HealthPro Compact secured an amazing efficiency of 99.95%, while Alen BreatheSmart 75i dropped to only 99.9%.

Also, in this high-range segment, the filter cost of this Blueair Classic 605 is really low, from  for a set of Particle filter. Compared with the cost of total  from the Alen BreatheSmart 75i or  from the Airmega 400S, we will be happier with this air purifier.

 Only one big issue, with only 6 months for this air filter to last, the cost to maintain this powerful machine still can cause enough headache to you.


The Blueair Classic 605 is the titan of room coverage. Its domain? An impressive 775 square feet. While the room coverage is still smaller than other high-range air purifiers, Blueair Classic 605 still can beat them all because of the high ACH and CADR rating.

  • Wipe down the air intake and outlet grills (as well as the internal fan) with a dry, lint-free cloth
  • Replacing the filters as needed, every 6-8 months as recommended by the manufacturer

All air purifiers manufactured from Blueair company can exchange air in the room coverage 5 times per hour.

With scores like 400 Dust/ 450 Smoke/ 450 Pollen (cfm), Blueair Classic 605 not only covers a vast territory but ensures the air in it is pristine.


Silent Nights: A low hum at 33 decibels, quieter than a hushed library, that’s the Blueair at its most discreet.

The Roaring Days: Turn it up and you’ll hear it. At 62 decibels, this isn’t the purifier you’d want in a meditation room.


One of our most FAQs is “Do air purifiers use a lot of energy?” An air purifier is meant to run for a long time to be efficient, that’s why many air purifier brands consider the energy-saving standard, mostly in the rate of Energy Star, is one important selling point.

Blueair answers with a resounding “No”. It’s a master of efficiency, drawing only 15 watts at its lowest, and 100 watts when turned up to 11. A year with the Blueair? Just to.


Smart Living: Missing a remote? Alexa’s got you covered. Plus, there’s the Blueair Friend App for those who prefer screens.

As a high-end machine targeting at home use, the Blueair Classic 605 makes use of a Night mode. It dims the lights and turns down the volume, ensuring you get that peaceful night’s sleep. 

In a world where automation is king, the Blueair 605’s lack of an air quality-adjusting sensor stands out unlike the Honeywell HPA600B or Rabbit Air MinusA2.

Every Blueair Classic also has a timer and indicator light.
