Suggested Air Sampling Filter Handling Techniques
  1. Avoid over-handling of filters as much as possible.
  2. Always handle filters with clean powder-free gloves on in the manufacturing, packaging, laboratory or other processing areas.
  3. Keep all filters in sealed plastic “zip lock” bags and use separate bags for clean and used filters. Never put used filters in the clean filter bag.
  4. Put tips on filters after turning pumps off. Avoid carrying filters without tips in place. Collect at least one filter blank for each monitoring period (day or shift whichever is shorter). A filter blank should be a clean filter with the tips reversed (as if a used filter) and placed in each bag with other used filters.
