The below listed organizations and governing bodies support the above comparison method and have determined that indoor mold spore levels should be similar in number and type to outdoor mold spore levels and types.A Micro5 non viable spore trap with pump calibrated and run at 5 LPM for. Thus, entire colonies can be examined in the lab for more accurate identification of mold types, sometimes even to the species level. This is very important because often spores can be allergenic or potentially toxigenic, regardless of whether they are live. The first four methods above are non viable spore traps, this means that live and spores are collected in the sample device to give an idea of the total estimated number of spores per cubic meter of air one time purchase of a reusable sampler as apposed to the free one time use plastic cassettes provided y labs.  

Outdoor Mold Spore Levels The most widely accepted guideline across the nation to help determine if indoor mold spore levels are indicative of a possible mold problem is the comparison of indoor and outdoor mold spore levels. It allows for the culture of live mold in the lab. Also, the Cyclex typically samples 200 liters or of a cubic meter of air, thats a good amount for an air sampler, the more air sampled the more statically reliable the results. The fifth method above is used for viable air testing. Surface sample methods just do not provide as much quantitative info as the following 5 air sample methods.. These mold testing methods have been proven over and over by time, legal trial, and third party scientific lab verification for reliability taking into account many complex factors related to aerodynamics and physics.00 for a stainless steel impactor plate with 400 tiny precession drilled holes, as apposed to a simple plastic air testing cassette provided for free by the lab.

A single stage viable impactor plate, such as an Andersen Impactor or one of it's exact duplicated clones.A CyClex-d non viable spore trap with pump calibrated and run at 20 LPM for 1 to 10 min. Viable sample means that only live mold colonies from live spores or live colony forming units are counted. Indoor mold spore levels should be similar to or lower than levels found outdoors, and the types of mold spores found in indoor mold test samples should be similar to types found in outdoor test samples. This sampling method does not miss spores. Though this method does not allow the counting of spores, it is a very important and respected sampling methodology used by professionals for around from the 1950's to the present. The Cyclex from method 28/415 Cosmetic packaging plastic bottle cap above is not used as much as some other methods because it requires a larger up front investment on the part of the mold testing firm.  

In addition to testing 200 liters of air with each sample the CyClex sampler developed by Environmental Monitoring Systems also has a cut off diameter the size of the smallest spores, this means tiny pen / asp spores just  microns  across do not pass through the device and escape unnoticed.Cell non viable spore trap with pump calibrated and run at 15 LPM typically run from 1 to 15 min. Also, viable sample results have a longer turn around time 7 to 10 days as apposed to about 3 days for viable methods.
