記得之前有人說過，true-HEPA的過濾效果會更好

True-HEPA並不是比HEPA更好的意思, 而是告訴消費者這是通過驗證的HEPA.
原因是因為之前出了太多類HEPA的濾網, 但是其實都是不合格廉價品.
以下來自維基百科:
"Today, a HEPA filter rating is applicable to any highly efficient air filter that can attain the same filter efficiency performance standards as a minimum and is equivalent to the more recent NIOSH N100 rating for respirator filters. The United States Department of Energy (DOE) has specific requirements for HEPA filters in DOE regulated applications. In addition, companies have begun using a marketing term known as "True HEPA" to give consumers assurance that their air filters are indeed certified to meet the HEPA standard.[5]
Products that claim to be "HEPA-type", "HEPA-like", "HEPA-style" or "99% HEPA" do not satisfy these requirements and may not have been tested in independent laboratories. Some of these sub-par quality filters may come reasonably close to HEPA filtration, while others will fall significantly short, making them truly inferior.[6]"
