A HEPA (High Efficiency Particulate Air) filtration vacuum cleaner is an important tool to minimize the effects of pollutants and other allergens, indoor air, whether to aggravate existing conditions or to prevent future health problems.
Because HEPA filtration is so desirable, the HEPA cleaners term is used to market a variety of vacuum, and is often applied in highly misleading that the vacuum can be difficult to chooseWipers>, filtration, levels, buy first.
The HEPA filtration specification consists of two numbers, description of a very high level of filtration of very fine particles. The first number is the percentage performance of the filter and the second number is obtained, the particle size. HEPA filtration efficiency must be retained for 99.97% of particles 0.3 microns and must be small (formerly Micron).
The phrase"As small as it is important is that if all particles were 0.3 microns in size, the filter would still be recognized and called to keep 99.97% of them (usually called" Separation ") is . The term "high up to 0.3 microns, is not to cover the same filtering performance as it can involve a mixture of particle sizes for specified performance.
The ability to filter very small particles is a very important statement, because small particles can quickly reach thedeeper in the lungs and after the U.S. Environmental Protection Agency, a wide range of extremely negative impact on health such as aggravated asthma, acute respiratory symptoms such as aggravated coughing and pain or difficulty in breathing, eye and nose causes coughing, breathing difficulties Infections and chronic bronchitis, decreased lung function, shortness of breath and lung cancer.
And for those who suffer from allergies, one of the most potent allergens, which is probably responsible for asignificant source of allergy is present in the faeces of house dust mites, which are generally larger 10-24 micron and even smaller when they found disturbed.
To give you an idea of how small these fine particles, a human hair is about 100 micrometers thick. HEPA filtration for 99.97% of particles to one third of a micron registered.
HEPA filtration is an important and valuable feature to have, as part of your vacuum cleaner. So how canYou can be sure that you are getting genuine HEPA filtration? Let's start with certified HEPA filters.
The HEPA filtration specification
The best HEPA filters are certified to strict standards, how to meet the European standard in 1822 (also referred to as EN 1822) for filtration performance and are identified with a certification number. Certified HEPA filters are also known as true or absolute HEPA filters. European companies often refer to it as a filter S-Class.
Originallydeveloped for evaluating filtration systems to maintain very clean environments in the pharmaceutical, computer, insurance, medical facilities and other clean-critical certification to this standard that the filter can serve as a true HEPA filter.
The EN 1822 is a test in two parts. The first part of the test identifies the particle size that penetrates more easily determine the HEPA filter, Most Penetrating Particle Size "or MPPS.
Once the MPPS isidentified the challenges of the second part of the examination will penetrate the filter only in particle size. When a filter for the filtration of 99.97% under the very worst to get, then you have a filter to provide true HEPA filtration.
And since the filter efficiency is strongly correlated with the speed at which the air through, this test is done at the same speed airflow Than When the filter is in force and the vacuum cleaner is running.
Thisis extremely important because any vacuum cleaner exhaust port to operate on the basis of air flowing from the opening of the cleaning head, through the vacuum cleaner bag and filter system and then. It is therefore logical that the HEPA filtration system is achieved when the filter (a filter or a series of filters that can contain the dust bag) 99.97% of particles smaller than 0.3 micrometers reserves.
When a HEPA filter is less than the actual airflow is testedwhen the device is used to be suspended, these small particles shot right through the filter into the air during normal operation. This is a way to filter, which failed to provide HEPA HEPA filtration in the real world.
Certification of the whole system
The important next question really is whether the air into the vacuum cleaner passes through the filter system. If the air leaving the vacuum beforeis filtered, a certain percentage of these are attributed to lung damaging particles and allergens, which were on floors and other surfaces in the room where the extremely light particles can circulate for hours. In this case, vacuuming even worsen the air quality at home.
Not only is a HEPA filter with standard EN 1822 certified crucial it is also important that detergent be sealed very well, so as not to leave the plane before theFilter.
To provide the highest filtration system in a closed system, there are several Now manufacturers of vacuum cleaners that use HEPA filters certified under the EN 1822 standard, but also try the vacuum cleaner around.
These companies offer proof that the loss from the filter and all air entering the device is HEPA filtered before leaves.
Therefore, to protect their health andSituations in which someone in your house is already suffering with a state that can benefit from a true vacuum cleaner HEPA filtration vacuum cleaner, certified the only way to get absolute certainty filtration, HEPA.
This does not mean that companies certify the entire vacuum cleaner is not air tight, before the filter but you must use your verdict. The companies that have certified quality vacuum cleaners also offerModels with certified HEPA filtration, even if the vacuum system is not certified.
Before heavy rubber seals in which the body meet, as well as other elements of high quality construction materials, such as high-performance plastics, which maintains its structural integrity.
The choice of vacuum in which the entire machine is not certified, make sure that the HEPA filter tested and certified with EN 1822. This is a strong indication thatDealing with a vendor to provide true HEPA filtration is serious.
If you click on a blank on the basis of something less than described, you may or may not always HEPA (or something close HEPA) filtration. The minimum standard should be that the manufacturer has a standard of performance and results of HEPA filters and particle size is maintained, so you can be sure that it is actually the standard HEPA 99.97% efficiency, capture small particles 0.3Micrometers.
Beware Deceptive Tactics
Unfortunately, the 'creative use "of the industry term is widely used in vacuum cleaner HEPA and we saw the" True HEPA "vacuum without demands on so-called efficiency or particle sizes listed. And the rest of the claims in their advertising that are not near HEPA performance.
The true HEPA performance is certified in some design challenges for manufacturers of vacuum cleaner. to create a closed system and in dealing with the increased air resistance of the true HEPA filtration and performance with the same excellent cleaning companies require a very high level of technology, design and manufacturing needs. This is one of the main reasons that this vacuum cleaner products cost more than mass market.
But a positive side to products from these companies is that they are so focused on producing some of the best quality> Vacuum cleaners available to provide superior cleaning performance and a pleasure to use.
Some companies also provide high-performance vacuum filtration levels that REACH does not provide the price for HEPA high efficiency filtration with a more affordable. offers Thus, for example, a filtration company that 99.95% of particles down to 0.5 microns and 94% of particles 0.3 microns to maintain. It can be updated many of these units into a true HEPA filter forAt any time. This vacuum cleaner can be an excellent value and provides a very high level of true HEPA filtration, so here only.
Attention to the deceptive tactics of many producers of vacuum cleaners. Some manufacturers are playing fast and loose with the term HEPA and requests as "traps 100% of the mites, ragweed and common grass pollen, with no mention of separation or particle size. Producers, that statements like those found on count ignorantConsumers the choice of their product is based on information that, at best, misleading.
The reality is that dust mites cause allergic reactions, it is an allergen in their fecal material, which is very small included. Mites are usually about 125 micrometers in length and most of the pollen 50-50 microns in size. The size of the grains are large and not nearly as small as 0.3 microns for true HEPA filtration is required. And this statement is also on a machineargues that the HEPA filtration, but not on separation or particle size.
In the evaluation of vacuum cleaners that offer housing under Advanced HEPA filter again, trying to secure efficiency and particle size evaluations as well as sealed up, so you can play a decision. If a producer does not show these figures is better somewhere else.
And a company's performance without filtering or particle size of government assistance The particle size without separation. One without the other is meaningless.
In summary, the filtration of fine particles can really improve indoor environmental conditions for people with allergies, asthma and other respiratory diseases and to protect the health of all persons in your home.
The best performance) will be cleaner, the use of HEPA vacuum cleaners certified EN 1822 (full vacuum, followed by high quality, well-sealed> Vacuum Cleaner with HEPA filter certified EN 1822. High filtration HEPA vacuum cleaner manufacturers and less well-known decisions may also be good, but be sure to check the product specifications for filtration and a particle size of very high quality.
