Thanks for the video, any plant recommendations for indoor purification ?
Yes. There is an increasing amount of evidence supporting wellness in these seemingly obvious tools. I also wanted to share some more on this thread page.
Moderate exercise, paying attention to your nutrition, sufficient sleep... all these are natural and will support your immune system and regulating hormones better.
... all kinds of stories of the shitty care people get when the hospital's understaffed or overcrowded.
I think, like a relationship, society needs to get through a bit of hardship to be healthy and we've had it pretty easy for a long time.
Many plants would die if treated like this, true. But many plants can and will shoot up from an established root. The point is that you have to get an established root on your tree or shrub first. In my area, willow, cottonwood, poplar, alder, birch, hazel, and maple would be good candidates. It is important that the plants not die, as a completely dead hedge becomes brittle (which a cow could force its way through, if it was hungry at corn time), and in my opinion is far too much of a fire hazard to keep around. There is a structure called a dead hedge, and you can search about it on this site, and some people advocate them as well.
I can imagine many shrubs not surviving such a rigorous chopping at their base. Seems like you would need some very hardy plants; Or do they not care if the plants die?
Sterilization using radioactive such as gamma rays has the potential to decompose the PP materials, using alcohol will erase the charges. However, charges are retained by exposing the masks in the hot air at elevated temperatures such as 70C for 30 minutes, which kills the coronavirus according to a report. But be sure to suspend the masks in the hot air without contacting or being too close to a metal surface because the metal temperature is much higher than that of the hot air leading to a severe charge decay or to the damage of the masks.
Q5: Can the masks be treated using steam?
A: Yes, our investigation showed that the charge loss on the electret is unnoticeable by sterilization using 125oC steam for three minutes.
My friend, Dr. Cai, a retired filtration testing scientist, had experimental data conducted in February 2020 as in the below table that support my above result in the past.
Steam treatment Experimental Theoretical Prediction
Initial FE (3-fold medical mask) 93.2% N95 (99%)
Steam for 5 minutes 91.7% 98.5%
Steam for 30 minutes 85.2% 97.5%
The first web link in Q3 had similar insignificant charge decay as above sterilized using hot water vapor.
Q6: Can the respirator be treated by boiling water?
A: Yes, our investigation showed that the charge loss on the media is unnoticeable in boiling water for three minutes but stirring on the mask is not recommended to avoid its physical damage.
My friend, Dr. Cai, a retired filtration testing scientist, had experimental data conducted in February 2020 as in the below table that agree with my above result in the past.
Boiling water treatment
Initial FE (3-fold medical mask) 93.2%
Boiling for 5 minutes 92.4%
Boiling for 30 minutes 83.6%
