{"product_id":"agh400-air-purifier-replacement-filter","title":"Airthereal AGH400 Replacement Filter | Glory Days Pet Air Purifier | H13 HEPA + Activated Carbon or Pet Deodorizing","description":"\u003cp\u003eThe filter is what defines the AGH400 — this is the replacement, built to the same standard as the original.\u003c\/p\u003e\u003cp\u003eEvery AGH400 runs on one of two filter configurations, and this replacement is available in both. The H13 option pairs true HEPA filtration, capturing 99.97% of particles down to 0.3 microns, with an activated carbon layer for general odors and harmful gases. The Pet Deodorizing option keeps the same H13 HEPA core but swaps in a third layer engineered specifically for cat urine, litter box odor, dander, and the allergens a standard carbon filter handles less effectively. Both are available as a single filter or a 2-pack, so the order can match the household's actual replacement schedule.\u003c\/p\u003e\u003cp\u003eReplacement is straightforward: unplug the unit, rotate the top counterclockwise and lift it off, rotate the bottom cover to access the old filter, and swap in the new one. Reassemble, power on, and hold the Filter Button for 3 seconds to reset the reminder. The AGH400 tracks this for you — the Filter light turns red at the 3,500-hour mark, or roughly every 6 to 8 months of typical use. Increased noise, decreased airflow, and a visibly clogged filter are the earlier signals worth watching for.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eProduct details:\u003c\/strong\u003e\u003c\/p\u003e\u003cul class=\"list-disc pl-8 mb-3\"\u003e\n\u003cli class=\"pl-2\"\u003eCompatibility: Airthereal Glory Days AGH400 Pet Air Purifier — this model only\u003c\/li\u003e\n\u003cli class=\"pl-2\"\u003eFilter options: H13 HEPA + Activated Carbon, or H13 HEPA + Pet Deodorizing\u003c\/li\u003e\n\u003cli class=\"pl-2\"\u003eH13 HEPA core: 99.97% of particles to 0.3 microns, both configurations\u003c\/li\u003e\n\u003cli class=\"pl-2\"\u003ePet Deodorizing layer: engineered for cat urine, litter box odor, and dander\u003c\/li\u003e\n\u003cli class=\"pl-2\"\u003eAvailable in single-filter and 2-pack quantities\u003c\/li\u003e\n\u003cli class=\"pl-2\"\u003eReplacement interval: every 6-8 months, or when the Filter light turns red\u003c\/li\u003e\n\u003cli class=\"pl-2\"\u003eReset: hold Filter Button for 3 seconds after installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhy we love it:\u003c\/strong\u003e\u003c\/p\u003e\u003cul class=\"list-disc pl-8 mb-3\"\u003e\n\u003cli class=\"pl-2\"\u003eSame H13 HEPA standard as the original unit — no drop-off in filtration between replacements\u003c\/li\u003e\n\u003cli class=\"pl-2\"\u003ePet Deodorizing option is a purpose-built third layer, not a generic carbon filter doing double duty\u003c\/li\u003e\n\u003cli class=\"pl-2\"\u003eChoose the quantity that matches your replacement schedule — single filter or 2-pack\u003c\/li\u003e\n\u003cli class=\"pl-2\"\u003eBuilt-in Filter light removes the guesswork on when to change it\u003c\/li\u003e\n\u003cli class=\"pl-2\"\u003eSimple twist-and-lift replacement process — no tools required\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eNative Manor Note:\u003c\/strong\u003e The AGH400 is only as good as the filter inside it.
