Can a Hepa Vacuum Cleaner Benefit Your Health?

HEPA filters were originally developed in the 1940s and used in the Manhattan Project to prevent the spread of airborne radioactive contaminants. After the 1950s, HEPA filters were later commercialized and the term became trademarked and known as a generic term to describe any high efficient filter. Over the years, because of demands for improved air quality in various industries such as aerospace, pharmaceutical processing, and healthcare, HEPA filters became commonly used in these industries to help eliminate airborne particulates such as dust, dander, mold, and asbestos.

In order to be considered a True HEPA filter, a filter must be capable of removing at least 99.97% of particulates as small as 0.3 microns. Particles of this size are the most difficult to filter, and they are thus considered the most penetrating particle size, or MPPS. HEPA filters consist of a mat of randomly arranged fibers that target and trap small particles by one of the following three mechanisms:

1. Interception - When particulates follow a line of flow in the airstream within one radius of a fiber and sticks to it.

2. Impaction - When large particles cannot avoid the HEPA fibers and are forced to imbed in one, which also increases with diminishing fiber separation and higher air flow.

3. Diffusion - When an enhancing mechanism results from the collision with gas molecules by small particles, which are impeded and delayed through the HEPA fiber.

Therefore, because of the superior filtration abilities of HEPA filters, they are extremely effective at removing particulates from the air and from surfaces such as carpets and upholstery, and their use can help make the air we breathe significantly healthier. Because our indoor environment contains allergens, chemicals, gas, dust mites, mold, and other harmful microorganisms, the respiratory tract struggles and suffers daily from these harmful pollutants. Poor indoor air quality can also cause symptoms such as itchy eyes, headaches, digestive problems, fatigue, congestion, and many more chronic and acute diseases. In fact, studies have shown that more than every one in three adult, child, or infant suffers from allergies, asthma, or respiratory diseases, and currently, asthma is one of the leading causes of upper respiratory illnesses in children.

Today, most HEPA filters can be found in air purification systems and even vacuum cleaners. HEPA vacuum cleaners use HEPA filters as part of the filtration process, and they are extremely beneficial for asthma and allergy sufferers, as the HEPA media is able to trap the fine particles that can trigger asthma and allergy symptoms. For a HEPA filter in a vacuum cleaner to be effective at particle abatement, the vacuum cleaner should be designed so that all of the air that is drawn into the machine is passed through the filter, with none of the air leaking past. In addition, because of the density of a HEPA filter, a HEPA vacuum cleaner will need a more powerful motor to provide sufficient cleaning power.

There are essentially two basic styles of HEPA vacuums: canister and upright. HEPA canister vacuums usually have smaller, stronger cases that can roll along and follow behind you as you vacuum carpet, furniture, or the floor. A long hose attached to a HEPA canister vacuum cleaner will help you clean hard to reach places. HEPA canister vacuums also often feature detachable rug beaters that are more powerful when compared to those found on upright HEPA vacuums. When the electric motor powered rug beater on a canister vacuum cleaner stops working, the unit can still be used to clean other surfaces. Overall, for homes with mostly bare floors and sparse rugged areas, canister vacuums can help you move seamlessly from one area to the next without scratching your floors.

On the other hand, upright HEPA vacuums consist of a single unit that may or may not come with an attachment hose to help clean hard to reach areas with specialized vacuum tools. Upright HEPA vacuums may leak dusty air back into your home, and since the rug beater bar is permanently attached to the vacuum's case, once this important component breaks, the entire vacuum will have to be replaced. However, if your home is mostly carpeted, a traditional upright HEPA vacuum may be a better choice, as its beater bar can better churn up dirt and dust embedded below the surface of your carpeting.

In terms of design differences, that are different styles of HEPA canister vacuums available, with the most common being those units with plastic cases utilizing a disposable dust collector bag made of plastic used to catch the dust from your carpet and into the vacuum cleaner. Keep in mind that with these types of models, dusty air may still leak through gaps in the plastic gases and even pass through the exhaust and back into your home environment.

When choosing a HEPA vacuum, also be sure to pay attention to the power of the model, as this is rated by its suction force in inches of water lift and by its air flow (in cfm). Anything with a 90 cfm or above is considered a powerful model and will effectively remove pollutants from your home. Also look to the position of where the HEPA filter is placed. HEPA filters in vacuums can be placed either before or after the motor, and some studies have suggested that a filter after the motor can help catch any fine carbon dust that is generated by the vacuum's motor. Strong seals to prevent leakage are also extremely important in vacuums that the filters after the motor.

Nevertheless, whether you choose a canister or upright HEPA vacuum cleaner, rest assured that it can help eliminate dust and dander from your home, and also alleviate your asthma-induced symptoms.

Particulate Materials (Hardcover) $388.92 Naturally occurring or manufactured through chemical and/or physical processes, particulate materials are substances consisting of individual particles which have significance to the global economy, society and environments. Due to the diversity and intrinsic nature, manufacturing, handling and processing of particulate materials still face numerous challenges. Aimed at addressing these challenges, this book contains a selection of papers discussing the state-of-the-art research in particulate materials science that were presented at the UK-China Particle Technology Forum III held at Birmingham, UK in 2011. Classified into four distinct topics namely synthesis, characterisation, processing and modelling, the chapters showcase the advances in these areas including for synthesis a range of advanced techniques for example spray-pyrolysis, supercritical fluid synthesis assisted with ultrasound, continuous synthesis using supercritical water, hydrothermal synthesis of nano-particulate materials and jet milling. For characterisation, various methods for characterising particulate materials at both particle and system levels are introduced and how these properties affect the behaviour of particulate materials in various processes, such as inhalation, filling, and consolidation, are discussed. In the processing section, recent advances such as capsule filling, micro-dosing, dry granulation, roll compaction, milling, and more are presented. The last section concerns mathematical and numerical modelling in particulate materials, for which the book includes both analytical methods and advanced numerical methods, such as discrete element methods (DEM), computational fluid dynamics (CFD), lattice Boltzmann methods (LBM), coupled DEM/CFD and DEM/LBM, and their applications. Particulate Materials is aimed at research communities dealing with these diverse materials, and scientists and engineers in powder handling industries, such as pharmaceutical, food, fine chemi

Particulate Morphology $100 Encompassing over fifty years of research, Professor Gotoh addresses the correlation function of spatial structures and the statistical geometry of random particle assemblies. In this book morphological study is formed into random particle assemblies to which various mathematics are applied such as correlation function, radial distribution function and statistical geometry. This leads to the general comparison between the thermodynamic state such as gases and liquids and the random particle assemblies. Although structures of molecular configurations change at every moment due to thermal vibration, liquids can be regarded as random packing of particles. Similarly, gaseous states correspond to particle dispersion. If physical and chemical properties are taken away from the subject, the remainder is the structure itself. Hence, the structural study is ubiquitous and of fundamental importance. This book will prove useful to chemical engineers working on powder technology as well as mathematicians interested in learning more about the subject. Concisely explains various mathematics and tools applied to the subject. Incorporates multiple fields to give a clear view of the application of mathematics in powder technology.

Particulate Emissions from Vehicles $145 The public health risks posed by automotive particulate emissions are well known. Such particles are sufficiently small to reach the deepest regions of the lungs; and moreover act as carriers for many potentially toxic substances. Historically, diesel engines have been singled out in this regard, but recent research shows the need to consider particulate emissions from gasoline engines as well. Already implicated in more than one respiratory disease, the strongest evidence in recent times points to particle-mediated cardiovascular disorders (strokes and heart attacks). Accordingly, legislation limiting particulate emissions is becoming increasingly stringent, placing great pressure on the automotive industry to produce cleaner vehicles - pressure only heightened by the ever-increasing number of cars on our roads.  Particulate Emissions from Vehicles addresses a field of increased international interest and research activity; discusses the impact of new legislation globally on the automotive industry; and explains new ways of measuring particle size, number and composition that are currently under development. The expert analysis and summary of the state-of-the-art, which encompasses the key areas of combustion performance, measurement techniques and toxicology, will appeal to R&D practitioners and engineers working in the automotive industry and related mechanical fields, as well as postgraduate students and researchers of engine technology, air pollution and life/ environmental science. The public health aspects will also appeal to the biomedical research community.

Particulate Gravity Currents $179.95 This volume arises from the conference Sediment Transport and Deposition by Particulate Gravity Currents held in the UK in 1998. The field of particulate gravity currents ranges from turbidity currents in the oceans, lakes and reservoirs to pyroclastic density currents and avalanches, debris flows and lahars, grainflows, powder snow avalanches, effluent dispersal and ancient gravity current deposits. Although the sub-division of particulate gravity currents into discrete sub-categories (such as grain flows, turbidity currents or debris flows) provides a convenient descriptive shorthand, it undermines the sense of process continuum needed to describe many natural flows. The structure of this volume reflects an integrative aim, with papers grouped by research approach. The first section of the book contains six papers on theoretical and numerical modelling of a range of flow types. The following four papers are focused upon combined theoretical and experimental modelling approaches. The next section contains four papers describing experimental modelling and the final section includes five papers detailing field-based studies. The volume stands as a testament to the broad range of research carried out on particulate gravity currents, and hints at the enhanced rate of progress that is likely to be achieved through further integrated studies.
