hot and humid climate, as is found in tropical and subtropical regions worldwide testing and adequate humidity control important to understand and solve a mold problem.

In fact, many coastal homes in Florida and the problems of South-East mold experiment in the absence of a leak. Many homeowners and mold inspectors do not understand the connection between the common building defects that cause moisture and mold problems. Sometimes homes by the sea have large permanent or recurring mold problems, which over many years.

After the text to all reliable experts, including, but not Bioaerosols assessment and control, inspection, cleaning and restoration institute S500 S520 restricted certification, the policies can become the EPA and mold more of a problem when the humidity about 60% to RH is 65%. Please note that 60% RH is not optimal, but maybe the humidity just enough to give a small amount of the drought tolerant to support forms. More moisture, mold growth occurs more.

Low humidity also cause problems. The humidity below 30% cause dry mouth, dry throat, and have other health problems, such as increased drying of mucous membranes, and increased risk of a cold. Low humidity may also increase static electricity, which in turn can damage the computer data. To be on the safe side, keep humidity between 30% and 60% RH.

Some types of mold commonly found inside xerotorlant pen asp. xerotorlant is only a fantasy, the resistance against drought. I wish to draw moisture from the molds forms. These forms, which by definition does not require as much moisture as other shells, but they still need moisture. You can grow in the absence of leaks, simply by living on the humidity (ERH) surfaces they absorb the growth in the wetlands. Just here is how it works. The air absorbs moisture from the growth surface such as drywall, wood or clothes, the humidity in these substrates as the equilibrium relative humidity increases in direct proportion to the known humidity air. This causes the moisture to mount available (WA) in the substrate. So that the moisture in the air ends up in your closet is absorbed and the drywall in your house, then the shape.

Humidity growth in itself, because mold is not the only concern of the high humidity. It will also prevent proper drying of wet surfaces when leaks occur. If you are experiencing your property on the beach, even in Florida, Louisiana and South Carolina, high indoor humidity and a leak, you are courting trouble. Especially if you out of town when all this because the leak is not dry before mold sets in

happens
The Inspector (DW) is often two types of molds xerotorlant again these forms do not need much water, but only what they get from moisture. A particular type of moisture pen asp mold xerotorlant love / black growing on clothes and black shoes and black leather wallet. Why mold like black clothes? It grows on all the clothes, but it is almost always completely invisible to other clothes, because the tool is small, white circles by 8.1 inches in diameter, which shows only black clothes. This type loves clothes, luggage, leather, wicker, and sometimes walls.

It starts first in your closet, as the drying air flow is generally lower cabinets.

If your mold inspector check your shoes and clothes are not found in panic, it only makes his work.

An important fact is that mold if it can be started for the first time almost completely invisible untrained eye, but it has been shown to cause seriously high levels of spores in the air, also you can mold wear on your clothes and assigned to smell fresh every day and the allergic reactions as a result long before we know what happened.

The other common mold moisture xerotorlant I know that grows in damp indoor demand, but not leak is a slow growing form of golden tan pen / asp. will be more precise, it is a kind of Aspergillus, the painted on lacquered wood, grow dry, and is on the books, it also forms colonies about 8.1 cm in diameter, such as white mold is not leaking into the top spot. If you see your mold inspector will find your books, it is not likely to read, but can be the verification of these colonies of mold. If you are familiar with the fax or yellowing of the old books and documents that you already have an idea of what it looks like mold. This form and oxidation resulting paper fax can sometimes confused with one another.

There are several ways that water or moisture can be measured in the air. Inspectors have two methods on a regular use in the testing of mold and moisture comprehensive investigations tests.

Humidity

Relative humidity compares the amount of water vapor present in the air were to be the amount of water vapor in the air when the air was saturated with water vapor.

Mixing ratio

Mixing ratio also measures the amount of water vapor in the air. But, mixing ratio measures the mass of water vapor at a given mass of dry air. In general, we have the shape of grains of water per kilogram of dry air. It is not Gramm grains.

HR vs. mixing ratio

It is a strange phenomenon to take into account when the measurement is the amount of water in the air with a relative humidity – the coldest a package of air, the more they take even if you do not get wet with water to it. And the warmest of an air parcel, less humid, it is even if you do not remove the water from there.

By measuring the amount of moisture in the air through the mixture, the temperature does not change the reading of the inspectors, the inspector measures the mixing ratio in areas where hot or cold temperature does not affect the readings.

Example I:

The interior of an attic in a tropical temperatures up to 100 ° C and relative humidity RH is 50%. This is an acceptable moisture, if only to examine the relative humidity. to many researchers Florida mold do not test, something of this band, with the use of a moisture meter, or a good scorer and a psychometric chart, we see that the hot air 100 ° F 50% RH actually contains about 145 grains of water per kilogram of air . This is what some of the large amount of moisture in your attic, if it is raining outside, it may not unusual, but when this amount of moisture still in your attic, you may have a problem, In fact, when a cold front moving in and the temperature dropped to 88 ° F in the attic at night, relative humidity 70% relative humidity. These are ideal conditions for molds and bacteria, and to take home to your invitation to accept. If a few nights later, the temperature drops to 78 degrees F at night, without adding more moisture from outside the humidity would go up to 100% in your attic, enters in this stage of condensation. The metal can rust and mold growing on the outer surfaces of your attic channels when the conditions are not improved.

Example II:

replaced in a hot and humid attic ocean breezes through the soffit vents to the attic attic temperature can be 100 ° F and humidity will reach 50% RH. This is an acceptable moisture, if only to examine the relative humidity. This hot air at 100 ° F 50% RH actually contains about 145 grains per pound of water by air. This is what some of the large amount of moisture in your attic, in should not cause a problem in your attic, but if you are near the ocean Breezy Southeast Asia, Hawaii, Florida to live the southeastern United States, it can, as in your attic, much of the summer.

When the sea breeze in your attic through soffit vents in your attic and blows the moist air into your attic, wall cavities seal and sanctify the house through an attic access over long or openings Light Hat in the ceiling, then the air temperature in the meeting of about 78 ° F.

Without the addition of new moisture from the outside, the humidity of the air leaking roof in your house would go up to 100%, so that condensation forming and causing the formation of mold on the ceiling where the cold air escapes from the attic, or in areas with a high cupboard, where the traffic is bad. This condition confuses many of our customers and even mold inspectors and other escape attempts to resolve the problem sometimes for years or decades.

And now?

If you are associated with moisture mold not only keep your shoes dry, have a day, you can find on your clothes, furniture, walls, books and art works to spread. Not ignore, not the setting of a shape-Inspector to a cheap, fast air samples are just wasting your money and time.

If you evaluate your problem correctly, you will find a complete examination of a building designed is to bring all the pieces together, it must, it must be by a professional engineer, licensed expert mold, or a certified occupational health physician will be conducted environmentalists inside which some knowledge concerning the construction, HVAC systems, the complex problems of damp and has mold and ecology. The person need to hire you to see where the moisture from there you must come to some ways to prevent this advice in.

In the attention that they need to keep your HVAC system so that it is properly dry your air evaluated.
