It installs in the factory filter location for compatible Palisade models and is built to the vehicle’s original fit specifications. The filter is intended for drivers who want a higher-grade alternative to standard paper cabin filters without changing factory airflow or fitment.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the PureFlow HEPA filter reduce particles inside my Palisade?\u003c\/h3\u003e\n\u003cp\u003eThe first filtration stage is true HEPA media rated at 99.97% efficiency for fine particulates at the rated particle size. That layer traps dust, pollen, mold spores, and similar airborne particles before they reach the climate control vents. Because it’s integrated into a four-layer assembly, particulate removal works alongside the other layers instead of replacing them.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-efficiency HEPA media captures ultrafine particles.\u003c\/li\u003e\n  \u003cli\u003eMulti-layer construction maintains consistent airflow.\u003c\/li\u003e\n  \u003cli\u003eDesigned to match factory cabin filter dimensions for proper sealing.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this filter help with odors and vehicle smells?\u003c\/h3\u003e\n\u003cp\u003eYes—the PureFlow uses activated carbon in its second and third stages to adsorb volatile compounds and typical cabin odors. One of the carbon-containing layers is enhanced with baking soda to target acidic and sulfurous smells commonly produced by food, spills, and trapped debris. These layers work by binding odor-causing molecules as air passes through.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo activated-carbon layers for wider gas and odor adsorption.\u003c\/li\u003e\n  \u003cli\u003eBaking-soda infusion helps neutralize common cabin odors.\u003c\/li\u003e\n  \u003cli\u003eInstalled between exterior intake and cabin vents for continuous odor control.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat is the purpose of the copper and silver ions in the final layer?\u003c\/h3\u003e\n\u003cp\u003eThe fourth stage contains copper and silver ions, which are included to target and neutralize certain fine contaminants that make it past previous layers. These ions are incorporated into the media to provide an additional protective layer that complements particle capture and odor adsorption. This final treatment aims to leave the outgoing air cleaner before it reaches occupants.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCopper and silver ions add an extra neutralizing surface.\u003c\/li\u003e\n  \u003cli\u003eWorks downstream of HEPA and carbon layers for layered protection.\u003c\/li\u003e\n  \u003cli\u003eManufactured to remain stable within the filter media for its service life.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow easy is this filter to install and maintain in a Palisade?\u003c\/h3\u003e\n\u003cp\u003ePureFlow HEPA cabin filters are made to match OEM size and mounting points for 2020–2022 Hyundai Palisade models, so installation follows the factory filter change procedure. No special tools or system modifications are required; simply remove the old cabin filter and replace it with the PureFlow unit in the same orientation. Regular inspection and scheduled replacement according to driving conditions will keep the system performing as intended.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDirect-fit for 2020–2022 Hyundai Palisade cabin filter housing.\u003c\/li\u003e\n  \u003cli\u003eTypical DIY installation using basic hand tools or dealer service.\u003c\/li\u003e\n  \u003cli\u003eReplace interval depends on mileage and local air quality conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: Ideal for Palisade owners who want a higher-performance cabin filter than standard paper elements—particularly drivers concerned about fine particulates, recurring cabin odors, or exposure to urban and seasonal allergens. It’s suited to those who prefer a drop-in replacement that matches factory fit while offering expanded filtration features.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is the PureFlow PC99525HX a direct fit for my 2021 Hyundai Palisade?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
