Key Points

Key Takeaways

  • 1

    The CO2 Problem

  • 2

    Cognitive Decline: Getting sleepy when working in closed room is not because of weak will. It is because carbon dioxide concentration is rising. Ventilation is the strongest boost means

  • 3

    Blueair Protect 7770i: Swedish air purifier specialty manufacturer. With 'HEPASilent Ultra' technology, removes 99% of virus level fine particles while filter life is long

  • 4

    Dyson Purifier Big+Quiet: Dyson's new professional level model. Has blowing ability to circulate air up to 10 meters away, does not let air stagnate even in large LDK

  • 5

    Visualization: Visualize invisible air dirt as numerical value (PM2.5, VOC, CO2). Build automation to automatically turn to strong operation if value worsens

  • 6

    Maintenance: Nothing is more troublesome than filter cleaning. Blueair is 'Just replace and throw away once every half year to 1 year'. Do you buy cleaning trouble or pay running cost

Introduction: Brain Performance is Determined by “Breathing”

Can you live in muddy water? You cannot. Then, can you live in dirty air? Unfortunately, many people are doing so.

PM2.5, pollen, house dust, and Volatile Organic Compounds (VOC). These are invisible, but surely enter your lungs, dissolve in blood, and cause brain inflammation.

“Head is not clear”, “Somehow sluggish”. The cause may be in that air you are breathing now.

1. The Heavyweight: Blueair Protect 7770i

There are two types of air purifiers. “Groceries” or “Medical Device Level”. Blueair is the latter.

Blueair Protect 7770i

Compatible with 70 tatami mats. With overwhelming air volume (CADR value), speed to physically replace room air is different. Smart filter equipped with RFID chip accurately grasps dirtiness and notifies replacement time to App.

GermShield Technology

The biggest feature of Blueair Protect is that it functions even when power is off. Temperature and humidity sensors constantly monitor, and when it becomes environment where bacteria easily breed, it automatically releases ions with breeze to inactivate viruses and bacteria in filter. In other words, it continues to function as air guardian 24 hours 365 days.

2. The Circulator: Dyson Purifier Big+Quiet

Dyson’s design is futuristic, but functions are also reasonable. Weakness of air purifier is “Cannot suck distant air”, but Dyson creates powerful circulating airflow.

Dyson Purifier Big+Quiet

Airflow reaching up to 10m away. Equipped with CO2 sensor, tells timing of ventilation. Quietness is dramatically improved, does not disturb conversation even in Max mode.

3. Comparison: Filtration or Circulation

項目 Blueair Protect Dyson Big+Quiet
Purification Speed (CADR) World Highest Class High
Air Circulation SpiralAir (Overall) Cone Aerodynamics (Powerful)
Sensor PM2.5, VOC PM2.5, VOC, CO2
Filter Maintenance Cost High (Replaceable) Medium (Long Life)

4. The Science of VOCs

New furniture, paint, adhesive, and air freshener. VOCs (Volatile Organic Compounds) are coming out from these. This is cause of “Sick House Syndrome” and quiet poison that takes away concentration.

Blueair and Dyson’s high performance models are equipped with activated carbon filter, adsorbing gas and odor in air. You should be surprised that “Smell of new construction” disappears quickly.

5. Automation Strategy

Essence of smart home lies in control of air quality.

  1. Monitor : Measure indoor CO2 concentration with Awair Element or Nature Remo E.
  2. Trigger : When CO2 concentration exceeds 1000ppm…
  3. Action :
  • Smart speaker shouts “Please ventilate”.
  • Circulator becomes maximum air volume.
  • (If any) Automatic window opening/closing machine opens window.

Only after doing this, we can regain “Human-like breathing”.

Conclusion: Investment with Invisible ROI

Even if you breathe clean air, annual income does not rise immediately, nor do muscles grow. However, please think of it as investment in your “Lungs” and “Brain” 5 years, 10 years later.

Improving quality of air you breathe every day is equal to or more important than caring about food and sleep. Let’s take a deep breath. Is air in your room delicious?
