Regarding HEPA filters, the more layers, the better, but why do HEPA filters of the same brand have different prices? Another way of asking questions is what are the differences between filters at different prices? In fact, we know that a brand of air purifier will have multiple series, corresponding to the three grades of high, middle and low, and the matching HEPA filter is the same. Different prices of HEPA filters use different materials, such as the five materials mentioned above: PP filter paper, glass fiber, composite PP PET filter paper, melt blown polyester non-woven fabric and melt blown glass fiber.
For example, the HEPA filter with composite PP PET filter paper has the advantages of low price, good heat resistance and chemical resistance.
In addition to different materials, HEPA filters at different prices will also have filter levels. For example, EPA (Efficiency Air Filter) is divided into E10, E11, E12; HEPA (High Efficiency Air Filter) is divided into H10, H11, H12, H13, H14; ULPA (Ultra High Efficiency Air Filter) is divided into U15, H16, H17 Three levels etc.
To sum up, it can be seen that the number of layers of the HEPA filter does not mean that the more the better. When buying an air purifier, just pay attention to the CADR value, the price of the HEPA filter and other factors, and figure out the real intention of buying the air purifier.
Of course, reasonable and scientific use of air purifiers is also very important. For example, use air conditioners indoors to achieve indoor air circulation and avoid bacteria breeding in enclosed spaces; and when used with air purifiers, HEPA filters can be replaced in time. Net, the effect of purifying the air in this way is far better than buying a multilayer HEPA filter.
