Tips on how to Select a HEPA Vacuum Cleaner


Some sort of HEPA (High-Efficiency Particulate Air) filtration vacuum cleaner is a vital tool to minimize the effects of contaminants and other indoor air impurities, whether they aggravate existing situations or prevent future health troubles.

Because HEPA filtration is very desirable, the term HEPA has been employed to market a wide variety of vacuum cleaners, plus its often applied in a remarkably misleading way that can help it become challenging to choose a vacuum cleaner that could provide the levels of filtration you aren’t buying it for, to begin with.

The HEPA filtration standards comprise two numbers that designate a very high level of purification of very fine contaminants. The first number represents the actual filtration efficiency as a percent, and the second number may be the particle size retained. About HEPA, filtration efficiency should be 99. 97% and contaminants retained must be as small as zero. Three micrometers (formerly microns).

The phrase “as little as” is important because it implies that if all the particles had been 0. Three microns in dimensions, the filter would nevertheless capture and retain 99. 97% of them (usually known as “filtration efficiency”). The term “down to 0. 3 micrometers in size” does not refer to the same filtration performance, as it might refer to a mixture of particle dimensions for the stated efficiency.

The opportunity to filter tiny particles is a critical specification because little particles can easily reach the actual deepest recesses of the lung area and, according to the U. H. EPA, may cause a wide range of very adverse health effects, for example, aggravated asthma, acute respiratory system symptoms including aggravated hacking and coughing and painful or hard breathing, eye, nose, as well as throat irritation, respiratory bacterial infections, and chronic bronchitis, reduced lung function, shortness associated with breath and lung cancers.

And for allergy sufferers, just about the most potent allergens, which are responsible for a significant percentage involving allergies worldwide, are found in airborne dirt and dust mite feces, which are generally twelve to 24 micrometers in proportion and even smaller when interrupted.

To give you some idea of precisely how small this acceptable debris is, human hair is around 100 micrometers thick. DUST filtration is designed to capture 99. 97% of particles are a third of one micrometer in size.

DUST filtration is an essential feature to have as part of your hoover. So how can you be sure that you will get a true HEPA filter? Let’s start with certified DUST filters.

The HEPA Purification Specification

The best HEPA filter systems are certified to meet strict standards, such as the European Tradition 1822 (also referred to as DURANTE 1822) for overall filtration performance, and are identified with an accreditation number. Certified HEPA filter systems are called True or even Absolute HEPA filters. Western companies often refer to all of them as S-Class filters.

Initially developed for rating filtration for maintaining extremely thoroughly clean environments in pharmaceutical, pc manufacturing, medical, and other clean-critical facilities, certification using this regular assures you that the filtration system will perform as a correct HEPA filter.

The DURANTE 1822 is a two-part analysis. The first part of the test pinpoints the particle size that a majority of efficiently penetrates the DUST filter to establish the “Most Penetrating Particle Size” or maybe MPPS.

Once the MPPS is usually identified, the second part of the analysis challenges the filter MERELY with particles of the most individual size. If a filter can certainly maintain 99. 97% filter or filtering under the worst-case climate, then you have a filter that delivers true HEPA filter or filtering.

And because efficiency is powerfully correlated to the speed in which the air passes through the separate out, this test is done using the same rate of air movement as when the filter was in place, and the vacuum cleaner was in use.

This is extremely important mainly because all vacuum cleaners operate determined by air flowing from the opening up at the cleaning head, over the vacuum cleaner and the bag in addition to the filter system, and then out the exhaust port. It makes sense in that case that HEPA filtration is achieved when the filter method (a filter or group of filters that can include the particle bag) retains 99. 97% of particles as small as zero. 3 micrometers.

If a DUST filter is tested from less than the actual airflow it will probably be subjected to when the unit is used; these small allergens can simply blow right through the filter into the room atmosphere during regular operation. This is certainly one way a filter that could be HEPA will not supply HEPA filtration in the real world.

Certifying the Entire System

Another critical question is whether or not each of the air going into the carpet cleaner passes through the filtration system. If air leaks out of the vacuum before it truly is filtered, some percentage of the people lung-damaging particles and also allergens that have settled on floor coverings and other surfaces are recirculated into the room air the location where the extremely light particles can easily circulate for hours. In this case, vacuum cleaning can worsen the home’s air quality.

So not only is a HEPA filter certified, making use of standard EN 1822 essential, but it is also important that the carpet cleaner be exceptionally well sealed so that air does not leak ahead of the filter.

To deliver the most significant levels of filtration in a closed system, some carpet cleaner manufacturers now use HEPA filtration certified using the EN 1822 standard. Still, they are also certifying the entire vacuum cleaner.

These companies are offering proof positive that simply no air leaks before the filtration and that all air that goes far into the unit is DUST filtered before it leaves.

Therefore, to protect your health in situations where someone in your residence is already suffering from a condition that could benefit from a true HEPA filter or a filtering vacuum cleaner, certified vacuum cleaners are classified as the only way to obtain total reassurance of HEPA filtration.

It won’t mean that companies that do not certify the entire vacuum cleaner flow air before the filter, but the truth has to use your judgment. Nokia’s certified vacuum cleaners offer high-quality models with qualified HEPA filtration, even though the total vacuum is not certified.

Hunt for heavy rubber seals the place where the housings come together, as well as other remaining high-quality construction, such as heavy-duty plastic that maintains it has structural integrity.

When finding vacuum cleaners where the whole appliance is not certified, ensure that the HEPA filtration is often analyzed and certified using the HIERDOOR 1822 standard. This is a reliable indication that you are dealing with a severe maker about delivering genuine HEPA filtration.

If you choose vacuum pressure based on anything less than the above, you may or may not be getting DUST (or anything close to HEPA) filtration. The minimum typical should be that the manufacturer defines a HEPA claim and expresses the filtration efficiency in addition to particle size retained so that you can be sure that it is the DUST standard of 99. 97% efficiency capturing particles no more than 0. 3 micrometers.

Keep in mind Misleading Tactics.

Unfortunately, the “creative” use of HEPA is rampant in the vacuum cleaner marketplace. We have seen so-called “True HEPA” claims on hoovers with no efficiency or molecule sizes. And the remaining portion of the claims they make in their advertising and marketing does not come close to genuine HEPA performance.

True, accredited HEPA performance represents several design challenges to carpet cleaner manufacturers. Creating a sealed method and dealing with the elevated levels of airflow resistance regarding proper HEPA filtration while keeping outstanding cleaning performance demand companies to meet very high engineering, design, and manufacturing specifications. This is one of the main reasons that particular vacuum cleaners cost more than mass-market products.

But an aspect benefit to products coming from these companies is that because they are thus quality-oriented, they create some of the very finest floor cleaners available that deliver excellent cleaning performance and are a pleasure to use.

Some organizations also produce very high-filtering vacuum cleaners that do not get to HEPA levels to supply high filtration at a cheaper price. For example, one business offers filtration that holds 99. 95% of allergens down to 0. 5 of your micrometer and 94% regarding particles down to 0. a few of a micrometer. And several of these units can be upgraded into a true HEPA filter whenever you want. These vacuum cleaners can be a superb value, delivering very high degrees of filtration just shy of authentic HEPA.

Beware of the particular misleading tactics of many carpet cleaner manufacturers. Some manufacturers enjoy fast and loose with all the terms HEPA and make promises such as “traps 100% connected with dust mites, ragweed in addition to common grass pollens”, devoid of any mention of filtration efficiency as well as particle size. Manufacturers who make statements like this rely upon uneducated consumers choosing all their products based on misleading information.

The reality is these dust mites do not bring about allergic reactions; it is an allergen in their fecal material, which is very little. Dust mites themselves are commonly about 125 micrometers longer, and most pollens are concerning 5 and 50 micrometers in size. These are substantial chemical sizes and nowhere near as small as the 0. three or more micrometers required for proper DUST filtration. And this promise is also on a machine this claims HEPA filtration, although it does not list filtration proficiency or particle size.

While evaluating vacuum cleaners that offer innovative filtration below HEPA, look for specific efficiency, particle size ratings, and highly sealed housing to help you make an educated decision. If the manufacturer doesn’t show these numbers, you’re better off someplace else.

And, beware of companies that may state filtration efficiency without a particle or a molecule size without filtration performance. One without the other will be meaningless.

In summary, filtration regarding fine particles can increase indoor environmental conditions if you have allergies, asthma, and other breathing ailments and protect the fitness of everyone in your home.

The best efficiency will be obtained using EN 1822  DUST vacuum cleaners (the entire machine cleaner), followed by high quality, adequately sealed vacuum cleaners using HIERDOOR 1822 certified HEPA filter. High filtration but much less than HEPA vacuum cleaners made by highly regarded manufacturers may also be good choices. However, be sure to look for both filter or a filtering and particle size technical specs in a highly high-quality solution.
