Effective ventilation after vacuuming
Ah, Mr. Kiyo, good to see you!
What's on your mind today?
Hello, Mr. Fuji! I've been pondering over an interesting aspect of room ventilation lately.
Did you know that after vacuuming, there's often a significant amount of dust and dirt particles suspended in the air?
Really? I never quite thought about that. I always assumed vacuuming just sucked everything up.
Indeed, it does remove a lot of dirt, but moving furniture and rugs causes the dust to swirl up in the room.
Oh, but that's not a issue.
I can open the window to let the fresh air into my room, just like you taught me last year.
Mr. Fuji, it's good to know that you've definitely grown.
But have you forgotten that I shared with you that there is also a faster and more effective way of ventilation?
Oh no, how could I forget! So, by using a cooker hood, we can expedite the ventilation process and let cleaner air into the room faster, right?
Yes exactly.
Thank you for sharing that insight, Mr. Kiyo. Your expertise never fails to impress me. Do you happen to have any data on how much faster ventilation occurs with a cooker hood compared to without?
Ah, yes, indeed I do, Mr. Fuji.
Your company, FUJIOH conducted a simulation* comparing the dust emmision rate with only the window open to ventilation with both the window open and the cooker hood on.
After 10 minutes, they found that using the cooker hood expelled 70% of dust compared to only 5% without it.*
Approximately 14 times* faster than when a cooker hood was not used? It's quite a significant difference!
Right?
*Calculated from the amount of dust particle residues obatined in the simulation
Analysis conditions
- Cooker hood is operated at "High" airflow speed, equivalent to 420㎥/h.
- The amount of dust particles floating in the room is 100,000 with a diameter of 4µm and a density of 3000kg/㎥ (typical dust in the Kanto region, Japan).
- External wind conditions involve a lateral wind speed of 1m/s from right to left, with windows opened in both the living room and kids room.
- There is no continuous 24-hour ventilation.
- Dust entering from the outside is not taken into account.
That's remarkable! Such a substantial change could make a world of difference in maintaining air quality.
Absolutely, Mr. Fuji. It's all about maximizing the effectiveness of our home appliances.
Thank you for sharing that insightful statistic.
I still have so much more to learn.
You're welcome, Mr. Fuji. I'm always delighted to shed light on ways we can enhance our living spaces for better health and well-being. That's what your company and the brand have been aiming to do.
