This serves as a \"pre-filter\" to capture larger dust particles, hair, and debris, preventing the inner HEPA pleats from clogging prematurely.\u003c\/p\u003e\n\u003cp\u003eAirflow Orientation: The sticker labeled \"out win\"  indicates the air discharge side. This is critical for maintaining the structural integrity of the pleats under pressure.\u003c\/p\u003e\n\u003cp\u003eEfficiency Grade: Standard HEPA filters in this form factor usually range from H13 to H14, capable of removing 99.97% to 99.99% of particles as small as 0.3 microns.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003e2.⁠ ⁠PE Sintered Air Filter (Porous Plastic)\u003c\/h3\u003e\n\u003cp\u003e\u003cbr\u003eThis white, rigid cylinder is a sintered filter made from High-Density Polyethylene (HDPE) or Ultra-High-Molecular-Weight Polyethylene (UHMWPE).\u003c\/p\u003e\n\u003cp\u003eManufacturing Process: It is created by fusing plastic pellets together through heat and pressure without melting them completely. This creates a tortuous, interconnected pore structure.\u003c\/p\u003e\n\u003cp\u003eKey Characteristics:\u003c\/p\u003e\n\u003cp\u003eSelf-Supporting: Unlike the HEPA filter, this requires no internal cage or external support; it is structurally rigid.\u003c\/p\u003e\n\u003cp\u003eWashable: These filters are generally hydrophobic and can be cleaned (backwashed or ultrasonically cleaned) and reused multiple times.\u003c\/p\u003e\n\u003cp\u003eChemical Resistance: Highly resistant to most acids, alkalis, and moisture, making it ideal for humid environments or air intakes.\u003c\/p\u003e\n\u003cp\u003ePore Size: Typically available in ratings from 5 microns to 100 microns. In medical or air compressor applications, a 20-50 micron range is common for protecting internal machinery from fine dust.\u003c\/p\u003e","brand":"Oxyrevo","offers":[{"title":"HEPA Air Filter (Composite Design)","offer_id":46640417308857,"sku":"AirFilterHEPA","price":150.0,"currency_code":"USD","in_stock":true},{"title":"PE Sintered Air Filter (Porous Plastic)","offer_id":46640417341625,"sku":"AirFilterSintered","price":150.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0701\/0146\/7321\/files\/WhatsApp_Image_2026-03-17_at_10.16.49.jpg?v=1773764330","url":"https:\/\/www.zenergyrecovery.com\/products\/oxyrevo-soft-shell-hyperbaric-replacement-filter-2-pack","provider":"Zenergy Recovery","version":"1.0","type":"link"}
