My 85‑year‑old grandfather passed away recently. I flew back to the city where I was born to attend his funeral. I grew up with him, so we shared a very deep emotional bond. When he was admitted to the hospital, imaging scans showed that his lungs had turned white. Given the ongoing COVID‑19 pandemic, it was almost certain that he had contracted the virus. The hospital said his body was too frail to survive, so they only provided oxygen support; he died two days later. He had been diagnosed with stomach cancer three years ago and underwent a total gastrectomy. Without a stomach, he became extremely emaciated. The cancer recurred six months ago, but because of severe malnutrition, the tumor grew very slowly. This time, however, the COVID‑19 infection overwhelmed his already weakened immune system, and he simply could not fight it off. He is the first person in my family to have died from COVID‑19.

@SarahMcGinger Thank you. It’s just tough to stick with traditional manufacturing these days, given how much easier to make money from AI, crypto, or stocks.

The recent chip shortage has become increasingly severe. I had to pay more than three times the normal price to urgently procure 5,000 chips critical for production through underground market in Shenzhen. This is arguably one of the negative ripple effects of the AI boom.😡

@caredscared_ The speed 1 of Wear is slighter stronger than the mini. And the speed 2 of Wear is much stronger.

If you're tired of your loved ones, colleagues, neighbors, enemies, etc., not understanding why you're so frustrated about the state of indoor air, send them this history that compresses a semester's worth of knowledge into 100 minutes! youtu.be/yuXVu595DBI?is…

Many people are interested in positive pressure systems. Let me give you an example here. If you have a sheltered platform outside your wall, you can cut a hole in the wall and point the air outlet of the 3Pro toward that hole. This can create a positive pressure clean airflow of up to about 600 m³/h, which dilutes excessive carbon dioxide, particulate matter, bacteria, viruses, VOCs, and other substances in your home that affect your health. The trade-off: keeping your home at a comfortable temperature will consume extra energy. But usually, each person in a room only needs 30 m³/h of fresh air. So you can set the device to a very low level, and that way, both the noise and energy usage will be minimal.

Heat exchange means you have to control the outgoing air, allowing the incoming and outgoing air streams to come into contact and exchange thermal energy. This brings up two issues: 1. If air is actively exhausted, the positive pressure of the incoming air is reduced. 2. The intake and exhaust vents end up very close to each other, which makes it easy for the exhausted dirty air to be drawn back in.

@chrisgj198 You need to reverse the fans if put inside the room. Heat exchangers is not possible on positive pressure unit because it don't control the air going out of the room.

Transferring bacteria and viruses from the air onto a filter and letting them stay there quietly to die off naturally is not called disinfection. The strict definition of disinfection is to kill bacteria and viruses. However, to save myself from trouble, I will remove all mentions of bacteria and viruses from my website air-fanta.com.

Based on my experience, you can't expect customs officers to clearly understand the difference between removing viruses and disinfection. If they inspect my shipments and see phrases like "removes viruses from the air" or "filters out 99.9% of viruses" in the product description on my website, they could easily mistake it for a disinfection product. I'm not blaming them; it's just that this distinction requires some specialized knowledge.

After Singapore, the COVID trend in China is picking up. The monthly report from CDC here and the posts on social media can confirm it.

I'm noticing that the COVID trend in Singapore is picking up. In week 13, it was only 3%. By week 14, it rose to 7%, and by week 15, it reached 8%. Not sure which variant is causing this. But it's possible that other countries could see similar situations. Here is the link to
