[Nhcoll-l] Air filtration (MERV rating) at collection rooms

[Hawks, Catharine]

Hi Miguel

You may want to consult the ASHRAE Handbook section on Museums, Galleries, Archives, and Libraries, which has information/recommendations for MERV filtration.

https://store.accuristech.com/ashrae/standards/a24-museums-galleries-archives-and-libraries-si?product_id=2573501

It sells for $55 USD, but is one of those publications that every museum should have on hand.

Dear all:

We will remodel a building that will harbour all our collections at the Galapagos Islands thanks to generous donations of donors. This building will have central AC control, and our architect is asking what level of air filtration (using the MERV rating) is the most recommended for collections. I am unaware of special air filtering conditions for collections, so I would think that anything in the MERV range 8-13 would be just fine. I would be very interested in knowing your experiences while choosing MERV rating filters for AC systems in collections.
