This is a device I use in my office: it draws outdoor air from outside the window into the room, passes it through a filter, and then vents it indoors. The excess air pressure pushes indoor air out through the gaps around the door. This way, indoor carbon dioxide, particulate matter, and VOCs can be reduced to very low levels. Even an air purifier with activated carbon cannot achieve this effect, because air purifiers cannot lower CO2 concentration. This device is modified from an AirFanta 3Pro. I reversed the fan installation and connected two reducing adapters so that the final diameter matches that of this plastic expandable duct. Finally, I sealed the window with a sealing fabric, leaving only an opening the same size as the duct. Its only drawback is the lack of heat exchange, so it requires some additional air conditioning load. It would be unsuitable in very cold or very hot places.

Recently there is a study of Long Covid in China. Scientists utilized cryo-electron microscopy to examine myocardial biopsy tissue from long COVID patients and found severe damage to the mitochondria within the cells. This organelle impairment cannot be detected through routine examinations.

I developed a meter to measure Co2 and particles for Covid cautious people. It is very popular in China. Now I made an English version of it. 🔻It contains a NDIR co2 sensor and a laser particle sensor. 🔻It shows particle quantity per liter, which is very rare in the market. It can give you more information when the air quality is 0μg/m3. 🔻It can be connected to an app on your phone through Wi-Fi. 🔻If you have a Tuya smart plug and connect it with the air purifier, you can set an automation to start/close the air purifier based on Co2 or PM2.5 reading on the meter. I haven't started to manufacture, if you have any suggestion, please let me know.

I made a new video to show not only how powerful the AirFanta 3Pro is, but also how compact and portable it is. It is the only air purifier on the market that have more than 400CFM CADR and be so portable at the same time!

We made a short video to show how powerful the 3Pro is on pulling the adjacent air. The smoke drifts in one direction in the beginning but is then drawn back toward the filters.
