Can HIV and other viruses pass trough 0.22 um filters?

Why are you guys suddenly worried about @MindlessWork cumming on your raws?

Seems someone has an obsession

Seems someone has an obsession

I know, right? Some of these guys are so obsessed, they're even worried about their raws. That's crazy!

Fixed.

Hiv is dying after some minutes out of the body.. in dry powders noz possible firthe virus to survive.. in oily gear with alcohol... Come on...

More interesting could be hepatitis c ... This virus is even more robust

...we have determined the diameters of mature and immature HIV-1 to be 110 to 128 and 132 to 146 nm, respectively...
Determination of the size of HIV using adenovirus type 2 as an internal length marker. - PubMed - NCBI

110 nanometers = 0.11 micrometers
Convert nm to um - Conversion of Measurement Units
so the HIV (AIDS) is half as big as the 0.22 um filters pore and can pass unfiltered

In the processing of biologics, viruses must be removed or inactivated, requiring the use of nanofilters with a smaller pore size (20–50 nm) are used. Smaller pore sizes lower the flow rate, so in order to achieve higher total throughput or to avoid premature blockage, pre-filters might be used to protect small pore membrane filters.
Sterilization (microbiology) - Wikipedia

The problem is that oil being so thick may not pass trough 20-50 nanometer filters.

And the HIV is a relatively large virus, most other viruses are smaller, so they can well pass trough unfiltered.


It looks like 70% ethyl alcohol degrades most viruses proteins, rendering them inactive on evaporation

You can pour raws on a beaker or shallow pan, pour enough 70% ethyl alcohol to fully cover raws, and allow it to fully evaporate to "kill" viruses.
Best if you only pour a shallow layer for faster evaporation.

At least the deadly Coronavirus can raise further awareness on steroid sterility.

Viruses tend to be fragile, holding at a specified low temperature in many cases should kill them. You would need a special oven that is capable of holding at an exact temperature for hours so you don't wreck your gear. You can build one with a PID controller, or I'm sure there are some commercially available at great cost. You would need to know the temperature when your gear begins to break down and the temperature when your targeted virus begins to break down.

This isn't a scientific study, you would want to do some research on google scholar.

While some scientific studies suggest that 62–71% ethanol, 0.5% hydrogen peroxide or 0.1% Sodium hypochlorite can innactivate some coronaviruses, however these studies should be taken with a grain of salt as they only apply to NATURALLY OCCURRING coronaviruses, not the MAN-MODIFIED CoVid-19.

Common sense tells that the CoVid-19 was probably engineered to be much more resistant outside living beings than its natural counterparts. Although we don't know for sure yet.

Anyhow, it's a great idea to soak up your raws in 70% alcohol and allow it to evaporate before brewing.
You can repeat the soak-dry procedure several times for extra safety.

So much BS.
By the time your cargo arrives from China the virus would be dead already.
