• Primarily culturable and total spore methods

• Also filter cassettes, biochemical assay or molecular techniques

  • polymerase chain reaction (PCR)

• Ex: Andersen N6, Aerotech 6, BioStage-1, Burkard

Total spore or spore trap: impaction onto prepared slide

• Ex: Air-O-Cell, Burkard, Cyclex

Filter cassettes: desiccates hydrophilic species

• nStill used, but obsolete (IMHO)

• Collection method for PCR assays
