RICHMOND FC PREMIERS 2017, 2019, 2020

Having just acquired a dehumidifier and with this and my AC now cranking 24/7 I wondered if any members have advice on ranges for both temperature and humidity. I followed a link on an earlier post which advised 20 degrees Celsius and 45% humidity. Do members accord with these numbers or wish to offer own advice.

Regards

re: Temperature & Humidity

The archival industry standard is a stable environment of 70°F (21°C) with a relative humidity held between 30% and 50%.

re: Temperature & Humidity

Hi Everyone;

@ Richmond & 51Studebaker;

Those numbers sound just right based on my experiences with stamps. Those temperature/humidity levels will prevent molds and stuck down stamps from happening.

@ Everyone;

The reason I mentioned in another thread about basements and stamps, is really quite simple. Cool temperatures and high humidity are bad for anything made from paper.

Also most consumer room size AC units will not work to reduce dampness in cool environments. The problem is the coils tend to ice up and stop functioning. So the only alternative is a dehumidifier. I would still recommend that stamps be removed from basements or just thrown out. Even dry basements seem to be bad for anything made of paper.

Richmond; I don't think that it is necessary to use a dehumidifier in the whole house, just the room where stamps or family photo albums and other treasures are stored. Good luck with your stamps, and hope you never have to soak valuable stamps apart.

Still just sortin'....

re: Temperature & Humidity

I keep the majority of my collection in a gun safe with 2 canisters of Damp-Rid which I empty every 3 months. The wireless monitor shows an almost constant temp of 72 and humidity of 42. It hardly changes throughout the year.
