How can I choose the best HEPA filter?
Filters
High particle efficiency filters are components used inside vacuum, air purifiers and other devices that help remove particles from the air. In order to be considered a filter HEPA, the filter must adapt to specific standards, ensuring that it can remove a certain percentage of particles from the air. All HEPA certified filters will work almost identical, as they meet the same standard, so the best of the filter that suits the device in which it is used and one that is most cost -effective. Some filters include additional features such as a layer of activated coal or the ability to be washed several times and reuse, although the efficiency of these properties is not regulated in the same way as the main components of the HEPA filter. There are some HEPA -like filters that are cheaper than the HEPA certified filter, although they usually do not meet the same strict instructions that the certified HEPA filter does and may not be able to capture very small particlese.
In order to bear the name "HEPA filter", a filter of air cleaning is required 99.97 percent of all particles that are 0.3 microns or more. When selecting the HEPA filter, this information is usually given on the packaging. In addition, when the filter has been certified as HEPA compatible, a specific serial number is assigned, which can also be printed on the packaging. Some filters claim to remove almost the same number of particles but are not certified. These filters are generally referred to as HEPA filters and can be significantly cheaper than the certified version, although the verification of the effectiveness of such a filter may be difficult.
above the certification is another aspect of selecting the best HEPA filter size, shape and manufacturer of filter. Some filters are boxes, some are rollers and others are thin panels. If you choose a HEPA filter that is not made by a company manufacturer's manufacturer is very importantMedium check of exact dimensions. Two filters that look like cylinders can have mild variations that make them different enough to be non -international.
The HEPA filter may have additional functions beyond the specifically needed. One of the common features is a layer of activated coal, which removes odors and some chemicals that do not lay the HEPA layers. Another feature is the ability to wash the filter so that it can be reused several times before the replacement, although the efficiency of the filter could deteriorate with each wash. Several filters, especially those designed for some industrial environments, may have ownership filter materials that increase the percentage of particles that are removed from the air, although these filter types may not always function properly in machines that are not designed for further air resistance they create.
