Air-O-Cell Bioaerosol Sampling Cassette 10-Pack by Zefon

Sold in packs of 10. The Air-O-Cell by Zefon is a single-use bioaerosol sampling cassette designed for rapid collection and direct microscopic analysis of mold spores, pollen, insect fragments, and skin cells. It uses inertial impaction at a precise 15 LPM flow rate to deposit particles onto a glass slide with adhesive collection media, with no additional preparation required before lab submission. Analysis is performed via direct microscopy. Shelf life is limited, check expiration date before use. Single-use only, not reusable.

What is the Zefon Air-O-Cell cassette used for?
It collects airborne biological and non-biological particles — including mold spores, pollen, fibers, and inorganic particulate — onto an adhesive glass slide via inertial impaction. The sealed cassette is sent to a lab for direct microscopy analysis, giving you a broad airborne aerosol snapshot for IAQ and mold investigations.
What flow rate is required, and why does it matter?
15 LPM is the required operating flow rate. The cassette's impaction geometry is calibrated for this velocity — sampling at a different flow changes particle capture efficiency and makes results incomparable to standard interpretation references. Verify flow with a calibration device before and after sampling and record both values.
Air-O-Cell vs. Anderson impactor — which should I use?
Use Air-O-Cell for total airborne spore counts via non-viable microscopy — it's faster and covers both living and dead particles. Use an Anderson impactor when you need culture-based, viable organism identification. For most mold investigations and IAQ screenings, Air-O-Cell is the standard choice.
How many cassettes do I need for a mold investigation?
AIHA and IICRC S520 guidance calls for at least one outdoor baseline sample, one per suspect area, one per non-suspect comparison area, and at least one field blank per shipment. A 10-pack typically covers a small-to-medium investigation with blanks included.
What's a common mistake that produces unusable results?
Overloading the slide by sampling too long in high-spore environments, which makes slides unreadable. Also: wrong flow rate, missing field blanks, and incomplete chain-of-custody documentation. Keep cassettes sealed until the moment you sample, and label immediately after collection.
What else do I need beyond the cassettes?
A calibrated pump capable of maintaining 15 LPM (such as the Zefon Bio-Pump Plus), flow verification equipment, chain-of-custody forms, and a lab arrangement for direct microscopy analysis. The cassette cost is typically the smallest line item — lab fees and pump rental are the larger variables.
Are Air-O-Cell cassettes rented or purchased?
They're purchased as single-use consumables, not rented — each cassette is one sample. A 10-pack covers most small-to-medium mold investigations including field blanks. Budget separately for pump rental (if needed), lab analysis, and chain-of-custody supplies — those typically outweigh the cassette cost on any project.
