摘要： The two-stage air filter is formed of a nonwoven glass fiber first or inlet filter element and a second or outlet filter element formed of nonwoven fiber. The outlet filter element is preferably formed of either polyester material, or a blend of polyester and cotton fiber material. The first or inlet filter element is coarser than the second or outlet filter element, with the first element serving to capture larger particles while allowing smaller particles to pass therethrough to be captured by the finer second filter element. The two filter elements have a continuous and unbroken, homogeneous interface therebetween, with the attachment of the two filter elements with one another being solely at their mutual peripheries by a peripheral frame. Additional air freshening and cleaning, deodorizing, odor neutralizing, scent applying, fungicidal, bactericidal, and/or germicidal chemicals or materials may be applied to either or both filter elements.
摘要翻译： 两级空气过滤器由非织造玻璃纤维第一或入口过滤元件和由非织造纤维形成的第二或出口过滤元件形成。 出口过滤元件优选由聚酯材料或聚酯和棉纤维材料的共混物形成。 第一或入口过滤元件比第二或出口过滤器元件更粗糙，其中第一元件用于捕获较大的颗粒，同时允许较小的颗粒通过，以被较细的第二过滤元件捕获。 两个过滤器元件之间具有连续且不间断的均匀的界面，两个过滤器元件彼此之间通过周边框架相互间隔附近。 可以将任何一种或两种过滤元件施加额外的空气清新和清洁，除臭，气味中和，香味施用，杀真菌，杀菌和/或杀菌化学品或材料。

摘要： One or two filters in brackets are integrated with a square or circular fan. Filters and associated brackets are provided both in the front and in the rear of the fan in one embodiment. In another embodiment, a single filter in a bracket is provided at the rear of the fan. The filter(s) can be pre-pleated and pre-activated carbon filter(s). The fan housing can include a pocket for adding an odorizing and/or deodorizing agent. A plurality of stick-on right-angled brackets having the capacity of adjustable clearance to snugly hold the filters is another embodiment.
