MoldCheck's National Research on Indoor Mold Spore Levels and Chronic Indoor Air Quality Irritability Symptoms

The objective of this page is to present the basic outline of our survey and ask you to participate by entering the results of your use of the MoldCheck™ Mold Test Kits. You can read our research ideas below or go directly to input your data.

We encourage you to take a minute to input your data and become a participant in the first of its kind National Indoor Mold Spore Levels and Illness Survey. This survey will allow MoldCheck™ users to insert their data into this statistical system so it can be analyzed and shared with other users and researchers.

Graph Key:

The graph below displays six environmental air quality relationships relating to airborne mold spores indoors and outdoors as detected using the MoldCheck™ Mold Test Kits.

This instructional graph shows a series of relationships which our research has shown to be fundamentally true.

We invite you to review this information and enter your MoldCheck™ Data in a first of its kind national survey on indoor mold spore levels and allergy type illnesses.

As more and more kit users share their data on their indoor mold spore counts, their indoor allergy symptoms and their discovery of the locations of indoor mold contamination, we will produce the national results in table and graph formats for kit users to see on line and be used by researchers, allergists and health officials.

The key code below the graph explains each of the mold spore relationship variables.


MoldCheck™ Users:

Individuals who purchase a MoldCheck™ Mold Test Kits generally have a suspicion that they have some type of Indoor Air Quality problem which is giving them chronic year-round allergy type symptoms.

There is no National Environmental Illness database to track indoor air related complaints and findings. There are no health related indoor air quality standards for microorganisms or their toxic off-gases.

This database of results from MoldCheck™ users will provide a first "rough cut" of real field data on sampling results, symptoms and problems discovered.


The purpose of this page on our web site is to gather MoldCheck™ user’s data to share with academic researchers, physicians, health officials and you concerning chronic indoor allergy-like symptoms and asthma health complaints related to indoor environmental air quality. We are specifically studying elevated mold spore levels coming from contamination originating somewhere within the building envelope.


The news is full of articles on the upsurge in asthma and the dramatic increase in the use of antihistamine medications to fight many allergy type symptoms. Teacher and student complaints and illnesses have led to the closings of schools for mold renovations in more than a few cases throughout the country. There are news stories about people forced out of their home by a "toxic mold", etc. etc. But these are extreme cases which get high profile attention and news play after years of complaints and expensive laboratory testing which confirms that hidden sources of indoor mold contamination are the culprit. 

Of greater significance, however, are the large numbers of people affected indoors with chronic year-round allergy and flu-like symptoms (headache, lethargy, itchy or burning eyes, sneezing, coughing, runny nose, etc.) These individuals suffer with lost workdays and medical bills for medications and dead-end physical exams which can’t seem to pinpoint a specific allergy or medical condition related to these symptoms. Often these individuals feel better when they are away from home or work for a week’s vacation or trip - but the symptoms return once they are back home or at work.

A recent study published by Dr. Sheryl Szeinbach of Ohio State University found that fully 65% of the patients on prescription drugs for allergy type symptoms did not have true histamine related allergies. Some other factor was the cause of their allergy-like symptoms.(Source: Robert Bozell,, May 29, 2001).

There is not yet any definitive clinical, toxicological or statistical evidence showing a causal relationship between specific levels or types or mixes of indoor mold spores and illness - although many scientists and allergists suspect it - and so do we.

Could it be that creeping indoor mold growth in aging and newer (but tightly built) homes with minor, chronic or unnoticed leaks is producing a mix of abnormally high irritating mold spores and chemical off-gasses? Many scientific studies are pursuing this theory – and so are we.

You will want to read an excellent article entitled, "Is Indoor Mold Contamination a Threat to Health?" by Harriet M. Ammann, Ph.D., D.A.B.T. Senior Toxicologist, Washington State, Department of Health.


Every doctor, allergist, and researcher agrees that the vast majority of allergic and asthmatic episodes (attacks) appear to be caused by external environmental triggers (microscopic particles, chemical odor irritants, cold air tissue shock). Consequently, doctors tell their patients to reduce environmental triggers as much as possible in their indoor environments.

Has the aging of homes (and increase in water leaks) and the greater air tightness of homes lead to a condition which is trapping abnormally high concentrations of mold spores and off-gassing chemicals indoors - we think so.

Patients can avoid irritating odors, cover their beds and pillows with non-allergenic fabrics and reduce humidity to kill dust mites and put in good furnace filters and room HEPA filters to lower overall airborne particle counts. However, the filters can never quite get the job done, if there is a hidden source of microscopic particle irritants constantly drafting into the indoor environment from an unidentified source (i.e., hidden mold growth in damp walls, floors, rugs, ceilings, fabrics, books etc.)

Novel Research:

Home Health Science, Inc. has embarked on a novel two-pronged approach to managing indoor air quality in order to lessen the frequency and severity of asthmatic attacks and chronic upper respiratory conditions while in indoor environments.

Our first research tool is the MoldCheck™ Mold Test Kits These kits will enable users to detect the rooms with the highest mold spore counts. Then guide them through a detailed search / inspection to pinpoint the source of the hidden mold and hidden moisture.

Our second research tool is the National Indoor Mold Spore Level and Illness Survey.
