First 12 hours of seasoning study comparing two 84% RH Pouches and HumiForm Mini Humidifier. The Mini is already above 70% relative humidity.
Questions: Can a humidor season too quickly? Should I reduce the amount of filament to maintain RH around 70% while the pouches catch up?
With pouches being our main competition, we decided it was time for a head-to-head comparison. For this study, we purchased two new and identical 50-stick humidors, two 84% relative humidity pouches and one 72% relative humidity pouch from a well-known manufacturer, and a holder with vented sides. The pouches cost about $6.5 each and the holder was over $23.
To season the humidors, we placed the holder containing the two 84% pouches in one humidor, and in the other humidor we placed a HumiForm Mini. According to the pouch manufacturer, seasoning should approximately take two week.
We have study starting soon comparing the HumiForm to pouches, from a well known supplier, each inside new identical humidors. The plan is to break the study into two sections: the first is to see how long it takes each humidor to become seasoned, and second to measure consistency of the relative humidity and how long each of the two humidifiers lasts before needing to be replaced (pouch) or refilled (HumiForm). To make the comparison more fair, we are planning to use the HumiForm Mini which holds about 35% as much water, or propylene Glycol mixture, as the HumiForm 50 V or 100 V models. Stay tuned.
I've broadened the topic to include pathogens that could include viruses, bacteria, and fungi - and coined the product name, ChloroCloud™. Due to the corrosive nature of chlorine, this version uses PVC tubing and fitting. I should mentioned that my experience with HCl gas and liquid chlorides goes back decades, and I was co-inventor on U.S. Patent 5,599,425, Predecomposition of organic chlorides for silicon processing, a commercial product sold by Air Products under the trade name, Trans-LC.
Today's check of the storage bin containing the ChloroCloud device 12 hours after increasing the concentration to 1 to 1 ratio of distilled water and standard laundry grade bleach. As noted in yesterday's post, the fumes are still noticeable and reminiscent of a hotel indoor swimming pool. I could envision this ChloroCloud device being placed inside a mailbox for months between refills and disinfecting mail.
In researching how long COVID-19 may survive on a surface, there is already quite a bit of information available. Site https://science.howstuffworks.com/life/cellular-microscopic/long-can-viruses-live-on-surfaces.htm references researchers at the National Institutes of Health, who tested forms of coronavirus. They found these viruses may live on plastic and stainless steel for more than 72 hours, cardboard for more than 24 hours, and copper for less than 4 hours.
The concentration of chlorine vapor will need to be balanced versus time needed to kill pathogens. The SDS (safety data sheet) from Clorox at https://www.thecloroxcompany.com/wp-content/uploads/cloroxregular-bleach12015-06-12.pdf mentions for handling to "Handle in accordance with good industrial hygiene and safety practice. Avoid contact with skin, eyes, and clothing."
Planning to reach out to CDC, NIH and known virus experts for ways to test the effectiveness of ChloroCloud at killing pathogens. I've also identified some commercial applications I plan to contact for possible collaborations.
Hello and Welcome to our first Blog for HumiForm. While this product was originally intended for humidifying cigars, we've had a moment of inspiration that maybe HumiForm has a place in the fight against the Corona Virus. This is NOT an area we've dealt with previously, so please bare with us as we proceed.
HumiForm draws water from a reservoir and transfers as water vapor inside a cigar humidor. What if we can deliver diluted chlorine vapor instead, using Sodium Hypochlorite (a.k.a. common bleach)? Would this create a way to disinfect your mail, packages or other items? We think so.
Testing is underway where we have initially mixed up a 4 to 1 blend of distilled water and bleach in a standard HumiForm reservoir, and placed inside a plastic storage bin with closed lid. Literature suggests that chlorine may kill viruses in a matter of minutes, although most of what we've uncovered is based on the use of liquids rather than vapor/fumes. We'd expect longer exposure to be necessary with HumiForm, with an emphasis on safety over speed.
Here are some photos showing the configuration of HumiForm with the water/bleach mixture in testing.
UPDATE: An hour into testing, the filament is soaked as expected, but the fumes are barely noticeable. Increased the strength to 2 to 1 distilled water to bleach.
Four hours into testing, the fumes are still barely noticeable. Increased the strength to a ratio of 1 to 1 distilled water to bleach.
Nine hours into testing, the fumes are fairly noticeable at a 1 to 1 ratio of distilled water and bleach. It's reminiscent of a hotel indoor swimming pool.
