Asbestos is best described as a type of mineral fiber that can be identified with the use of a microscope. Although people usually use the term asbestos when talking about this fiber, there are actually several different types of asbestos fibers. In the early1900s, scientists discovered the first case of Asbestosis, which is progressive fibrosis of the lungs. In 1931, the term Mesothelioma finally found its way into medical literature. This rare type of cancer can be caused by asbestos. By the 1970s, asbestos was finally banned from being used as a building material in the United States. Although asbestos cannot be legally used any more in the creation of homes, there are still many old buildings in which asbestos was used in some fashion. A lot of homeowners find that old pipes or ducts are covered or wrapped in an asbestos compound. This is because asbestos was often used as a type of insulation. Due to the fact that asbestos flakes and crumbles very easily, it is recommended that anyone who buys old houses should have them checked for the fibers.

Once asbestos starts to flake, it releases very harmful dust into the air. Since the dust released by asbestos is known as a risky carcinogen, which can cause lung cancer, it is always recommended that the homeowner hire professionals to remove asbestos from a home. In some cases, asbestos can be enclosed and left alone. Only a professional can tell a homeowner if the asbestos has started to degrade to a point where it needs to be removed. Since there are strict regulations in the removal of asbestos, it is recommended that homeowners contact professionals to remove it. Labor costs related to the removal of asbestos usually rage from $200 to $700 per hour. Before hiring a contractor to remove asbestos, however, the homeowner will need to start with an inspection. This needs to be done both prior to and after the removal of the asbestos to make sure it has all been removed. The cost of doing a pre- and post-asbestos inspection is usually around $600 to $1,000. Thus, the overall cost of inspecting a home for asbestos and having it removed will usually run between $800 and $1,700, depending on the state and city in which the home is located.

One reason why removing asbestos from a house costs so much is because of the special gear and materials that contractors have to use to safely remove it. This may not be a complete list of the materials that professional contractors need to remove asbestos from a home, and the prices are based on an average. The cost of each unit may be higher or lower.Respirators - $150 per unitEyewear - $20 per unitDisposable Coveralls - $50 per unitRubber Boots - $30 per unitDisposable Gloves - $10 per boxHEPA Vacuum - $1000upholstery wet vacuum cleaner When a contractor is cleaning up all of the asbestos after removing it, they will likely use a High Efficiency Particulate Air vacuum. karcher vacuum cleaner onlineIn order to be considered a HEPA vacuum or an HEPA filter, it has to remove at least 99.97 percent of all particles that pass through it. miele handheld vacuum cleaners review

The smallest size that the filters can catch is usually 0.3 microns. This is a very important number because the most common dust size that comes from asbestos is 0.5 microns, but there are some rare forms that can be smaller. These types of vacuums are very effective in cleaning up the dust that is left behind by asbestos. It is generally recommended that homeowners clean their entire house with a HEPA vacuum whenever they have had asbestos removed. This ensures that all of the particles that might have been left behind are safely disposed. Not all HEPA vacuums are perfect for cleaning up asbestos. Just like any other product or device, there are a number of varieties of HEPA vacuums. Some of them simply work better than others. While some HEPA vacuums can be purchased for as little as a few hundred dollars, these are usually not industrial strength and will not do a great job at removing all of the asbestos. One of the key things that homeowners should keep in mind is the maneuverability of the vacuum.

This should be one of the primary concerns. That being said, the maneuverability must be properly balanced with the power of the vacuum. If it is a large project, a larger HEPA vacuum is going to be needed. The homeowner will want a large vacuum to make sure that the job goes quickly. At the same time, the larger the vacuum, the less maneuverability it has. There are three major types of asbestos to worry about, and each one has a different fiber size. Thankfully, most of them are large enough to be picked up by a HEPA vacuum. The most dangerous type of asbestos is crocidolite. This asbestos ranges in size between 0.7 to 0.9 microns. A very rare type of asbestos is amosite, and it ranges in size from .20 to .26 microns. This is the only type of asbestos that can pass by most HEPA vacuums, unless it is industrial strength. Last is the most common type of asbestos, Chrysotile. The fibers that make up this asbestos range in size from 0.5 to 0.6 microns.A HEPA air purifier is a filter used for cleaning air.

HEPA stands for "High Efficiency Particulate Arrestor Air filter." This air filter is used to improve the quality of air and clean equipment such as vacuum cleaners and other similar types of appliances. Mostly, HEPA air purifiers can screen different airborne particles, like asbestos measuring around 0.3 microns. The reason why many experts note the use of HEPA air purifiers is that they are so efficient. The efficiency rating of a standard HEPA air purifier is around 99.97%. HEPA purifiers are deigned to filter some of the hardest particles to screen. These particles include smoke, animal dander, dust, dust mites, and asbestos residue. HEPA air purifiers have been useful for many different companies, such as air pharmaceutical sites and areas that have had toxic spills. Especially for buildings, HEPA air purifiers are mainly used to remove and filter asbestos. The following section discusses how these air purifiers remove asbestos and other particles from specific locations. The HEPA air purifiers have specially designed air filters that are capable of trapping different allergens and particles, such as asbestos.

The screen-like construction of the filters absorbs or traps the particles while letting clean air pass through. Many professionals note that in order for an area to be completely asbestos-free, it’s important to use the air purifier a number of times. All asbestos particles that may have eluded the filters during the first try will definitely be trapped the second time. The more the air purifier is used, the better the quality of the air. There should be a higher exchange rate of air to ensure that air quality is at its best. However, it is important to note that one HEPA air purifier can clean only one place at a time. You cannot simply assume that all connected rooms will be cleaned just because the door is opened. For example, a HEPA air purifier inside a bedroom can only clean the air within that room. The living room and other areas should be purified at a different time since they are not cleaned at the same time as the bedroom. There is a limit to the scope of each HEPA air purifier.
