How To Test For Mold In Air

Where To Take A Mold Air Sample And Ideal Conditions

How to Air Mold Test the Right Way and Avoid Overpaying for Mold Remediation in East Tennessee.

Air samples can be taken to help verify and gather more information in any areas of a house suspected or confirmed to have mold growth. Moisture intrusion, water damage, musty odors, apparent mold growth, or conditions conducive to mold growth are all common reasons to gather an air sample.

Samples typicallyshould be taken near the center of the room, with the collection devicepositioned 3 to 6 feet off the ground.

Sampling should take place in livable spaces within the house under closed conditions in order to help stabilize the air and allow for reproducibility of the sampling and measurement. While the sample is being collected, windows and exterior doors should be kept closed. It is best to have air exchangers or fans that exchange indoor-outdoor air switched off during sampling.

Weatherconditions can be an important factor in gathering accurate data. Severe thunderstormsor unusually high winds can affect the sampling and analysis results. High winds or rapid changes in barometric pressure increase the difference inair pressure between the interior and exterior, which can increase thevariability of airborne mold-spore concentration. Large differences inair pressure between the interior and exterior can cause more airborne sporesto be sucked inside, skewing the results of the sample.

Musty Odor When Hvac Is Running

If you are running your HVAC and smell a musty odor, the potential for mold in the vents is high. Mold has an odor that is considered to be earthy or musty. The odor wont be good on the nose, but its one of the more recognizable signs that mold growth is present and can be detected easily.

If the mold is growing in the ducts, the smell might even spread throughout rooms that are near the source of the growth. Any strange smells similar to that of mold in your rooms means you should check nearby vents immediately, as it could be a telltale sign you have mold in the air ducts.

How Are Mold Air Test Samples Examined In Thelaboratory

Mold spore sample slides are prepared in the laboratory and then examined atmagnifications from 100x to 1920x to identify the dominant or other indicativeparticles collected. Particle counting, such as spores/M3 of air, ifprovided, is performed at 400x, 480x, 720x, 1000x, up to 1920x.

Somecompanies also use polarized light and darkfield methods and a variety of slidepreparation chemicals and stains.

Poor Reason For Testing #7 To Make A Party Respond To The Problem

There is no legal requirement to correct a mold problem in most residential or occupational settings. Collecting mold test results does not change this fact. While common sense supports the importance of correcting indoor mold problems quickly and effectively, there is rarely any rule or law that requires a property owner to do so.

Private homeowners are responsible for deciding how they will respond to real or suspected mold problems. This includes owner-occupied condominiums and townhouses, although issues of preventive maintenance and liability may be more confusing when an association is involved. Their insurance company may or may not cover any related costs depending on the details of their policy and other factors. In occupational settings, mold and any related health concerns are solely the responsibility of the employer and/or the property manager. In leased space, terms of the lease agreement may or may not address responsibility for mold and air quality complaints.

In rental housing, tenants should promptly alert the property owner or manager to evidence of mold or moisture problems if they cannot fix the problem on their own. Tenants concerned about mold in rental properties may also ask their city or county housing officials for help. If and how local authorities address mold complaints in rental situations depends on the status of local codes or ordinances and what authority the local program has to deal with this issue.

Limits To Mold Detection

Ottawa Mold Testing, Detection &  Air Quality Inspections

Air quality monitors are amazing devices, giving you the information you need to act and improve your air quality. However, your air quality monitor isnt infallible, and it has certain technical limitations that reduce the usefulness of mold detection.

Your particle detector measures the number of particles in your air, not what kind they are. It cant differentiate between the mold spores in your air and other particulate pollutants, so it just counts them all as particulate matter. Furthermore, spore size depends on species, so some mold spores may not fall into the simple categories of coarse particles or fine particles and wont be counted.

Additionally, mold isnt just mold. Mold is actually a nonscientific term used to refer to a group of fungi, not a specific species. Just as the sensor wont tell you how many of the particles are mold, so too will a general mold count not tell you what kinds of mold are in your air. Theres a massive difference between the health implications of simple mildew and black mold , and you cant effectively make decisions about the health of you and your loved ones without knowing if youre dealing with run-of-the-mill allergenic molds or the more serious pathogenic and toxigenic mold species.
