Indoor Air Quality

Indoor Air Quality Sampling Cassettes

Sampling cassettes are a convenient and reliable way to test for various indoor air quality (IAQ) factors. When used with a standard pump, they facilitate fast collection while maintaining the integrity of the sample for later analysis. As a result, they are ideal for home inspections, allergy testing, flood damage restoration and other applications.

Zefon International sells a wide range of indoor air quality sampling cassettes, including our proprietary Air-O-Cell® products. Shop our online store to explore our catalog or get in touch with our head office for more information about any of our products.

What Is an IAQ Cassette?

IAQ cassettes collect samples that are used to diagnose air quality issues such as mold spores, pollen, fly ash, inorganic dust, and other airborne allergens and hazards. Due to their popularity as the method of choice in testing for airborne mold, they are often also called mold cassettes. 

Air-O-Cell® IAQ Sampling Cassettes

The Air-O-Cell® product line contains some of our bestselling products. The first choice of air quality professionals, Air-O-Cell® sampling cassettes provide a quick method of collecting particles from the air that can be tested for a wide range of viable and non-viable aero-allergens, including pollen, mold spores, insect parts and more.

Air-O-Cell® cassettes employ a process known as inertial impaction, where a pump draws air through a small inlet slit, which in turn directs it to a slide containing a collection media. There, the particles impact on the media while the air flows through. The media holds the particulate in place, eliminating the risk of blurring, washing off or other damage during handling and shipment.

Use Air-O-Cell® cassettes with any pump with a 15 LPM open flow rate and are commonly used with our portable battery power Bio-Pump.

MoldSNAP™ Sampling Cassettes

MoldSNAP™ is designed as a first-line mold screening tool that can be easily used by home inspectors to get preliminary information on whether a mold problem may exist and further investigation is warranted.

MoldSNAP is a type of "spore trap" impactor that uses slit impaction as the collection mechanism. This is important as slit impaction is not only the most reliable collection method, it is an industry-recognized method that allows superior mold spore collection.

Accessories and Starter Kits

Sampling cassettes are one component necessary for indoor air quality analysis. Most are designed to work with an air sampling vacuum pump such as the Zefon Z-Lite™ or Zefon Bio-Pump. It's for this reason that we offer several convenient starter kits consisting of a pump, accessories and a selection of IAQ sampling cassettes. We also sell accessories and replacement parts - such as wall sampling adaptors and other items.
