HEPA filter ("Folter"): description and reviews. HEPA filters for vacuum cleaners
Air filters are produced by Folter. You, for sure, met modern vacuum cleaners, which recently are increasingly equipped with HEPA filters. Below you can find information that describes the characteristics, as well as feedback, to understand whether it is worth buying a technique with this principle of cleaning.
If you translate from English the abbreviation HEPA,then it means highly effective particle retention. Such devices can be attributed to filters that provide the most fine cleaning. Their effectiveness is proved by laboratory tests. For such tests an aerosol is used, in a mixture of which synthetic microparticles are present, their size varies within 0.3 μm. HEPA filter "Folter" can refer to one of the classes, depending on the fraction that will be delayed by the device. Thus, HEPA 10 is able to retain microparticles in a volume of up to 85%, their size will change to 0.5 microns. If the figure under the abbreviation increases to 11, then the filter will be able to hold up to 95% of the particles, the number 12 indicates the ability of the device to hold up to 99.5%. Figure 13 indicates that the filter will cope with cleaning 99.95% of sewage.
What does the filter look like?
HEPA filter "Folter" can be made ofdifferent materials. The latter can be disposable or reusable. In the first case, cellulose is used as the base, which is added to the glass fiber during the manufacturing process. If we are talking about reusable filters, they can be cleaned, they are made of fluoroplastic fibers.
In order to provide a lower levelresistance to air flow, similar devices have a larger filter area. To do this, they are performed on the basis of a material consisting of folds. This indicates that the device is made in the form of accordions. Fibers are glued together in a large frame. If you have a small size filter, you should be aware that it has a small filtering area. Such surfaces will quickly clog, creating an additional barrier to air flow. This can cause a reduction in the suction power of the vacuum cleaner. The motor may overheat.
Feedback on the effects of engagement and inertia
If you are interested in the HEPA filter "Folter", thenyou should know about what and by what principle it catches. When operating the described device, several mechanisms are used, as one of them the effect of engagement is applied. According to consumers, all the particles that need to be removed from the surface, from the largest to the smallest, will pass through the microfiber, clinging to them and sticking to them. They will cling to other particles that have previously stuck to the fibers. Buyers also point to the inertia effect, which is used by the HEPA filter. It is especially effective for large particles. The latter are unable to circumambulate the fibers, they lack the ability to follow an uneven trajectory. For this reason, they will continue to rectilinearly move until they encounter an obstacle.
Feedback on the effect of diffusion
HEPA filter "Folter" uses in its workanother principle, which is called diffusion. Users of vacuum cleaners, in which such filters are installed, note that this effect contributes to catching the smallest particles, their size can vary from 0.01 to 0.1 μm. This principle can be called dominant at low airflow rates.
Filter service life
If you use Hypa filters Fyas-Folter,then you should know that they can only retain their abilities for a certain time. Microparticles of the mentioned sizes will be retained until they accumulate on individual fibers. If the whole place is occupied, the dust begins to stick to each other, clinging to the fibers of impurities. If the filter is used more than the time it is designed for, then it will lose its characteristics, this will lead to a decrease in the ability to suck. The work of the vacuum cleaner will be accompanied by the release of an unpleasant odor. In order to exclude such consequences, the spent filter should be replaced with a new one. If it is a waterproof device, then it must be rinsed.
Feedback on the operation
If you use a HEPA filter for a vacuum cleanerGorenje 253263, it is important to know about the features of its operation. A number of owners who use disposable filters make the decision to blow the device through compressed air, directing it in the opposite direction. It should be noted that such an approach is able to rid the fibers of only 80% of large particles, the size of which exceeds 1 μm. It is these elements that cause clogging of the filter, and their elimination allows only to reduce the resistance to air flow. The described technology helps to cope with 30 percent of poorly confined particles, whose fraction is 0, 1-1 μm. As for the remaining 70%, these elements will be as tightly and firmly retained on the fibers, they will not be able to get rid of them in this way. More experienced users emphasize that after several similar procedures air purge will not have a restoring effect on the filter. However, you can use these manipulations to clean waterproof devices. Use for this compressed air is not recommended, but it is possible to make a washing. At home, the use of water for the filter will be most effective.
Is it worth combining HEPA and aquafilters?
Users are often interested in, you canwhether to combine a HEPA filter for a Samsung SC6570 vacuum cleaner with an aquafilter. Experts argue that with small bubbles of liquid, small dust and other contaminants will penetrate the filter. It will also receive fairly large particles of dirt. However, even more troubles will cause the growth and growth of bacteria, fungi and mold, which will be located in the fibers. Warm and moisture-laden air, which contains a huge amount of dust, will create favorable conditions for the reproduction of bacteria. Thus, with the above mentioned devices working in tandem, you will sow the whole apartment with spores of microorganisms.
If we conclude on the above, it is worthnote that the use of combinations of the two filters is desirable only in the event that the described device will often be replaced. However, users often refuse water-resistant HEPA filters, which presuppose the possibility of water purification, for the reason that they are quite expensive, and their intermittent replacement can cause gaps in the family budget.
Is it worth combining the HEPA and the cyclone filter?
HEPA filter for the Zelmer vacuum cleaner in somecases try to use with a cyclone filter. The latter has unique design features, due to which a large number of small particles are passed to the second filter. This soon clogs the microfiber, as a consequence of the decline in filtration efficiency. At work of the vacuum cleaner the unpleasant smell is allocated. If small particles are added to large particles, this will reduce the suction force, the motor will overheat and may fail. If you decide to use a HEPA filter for your Philips vacuum cleaner together with a cyclone filter, you should use the same technology as described above. It involves a fairly frequent change of the device, water treatment of the fibers. The air used for cleaning does not always lead to the desired result. To achieve the effect in this case it is impossible, and the use of household appliances without consumables turns into inefficient cleaning. Then the effort will be futile.
