Airthereal AEH300 Replacement Filter | Ethereal Rain Air Purifier + Humidifier | H13 HEPA, Humidifier Filter, or Combo Pack

The AEH300 runs on two separate filters — one for the air, one for the water — and this covers replacement for either, or both at once.

The 2-Pack HEPA Filter maintains the purifier side of the machine: a three-layer build of nylon pre-filter, H13 HEPA core, and activated carbon, capturing 98% of airborne particles including dust, pollen, pet dander, and smoke, with the carbon layer absorbing household odors, VOCs, and gases like formaldehyde and toluene. The 2-Pack Humidifier Filter covers the other half — the evaporative pad that filters water before it becomes moisture in the air, keeping the AEH300's no-mist, no-white-dust humidification working as designed. For households replacing both at once, the Combo Pack bundles 2 Humidifier Filters with 1 HEPA Filter, matching how the two filters wear at different rates.

Each filter has a defined lifespan: the HEPA filter runs 6 to 8 months depending on use, the humidifier filter closer to 6 months on its own — which is why the combo pack leans toward the humidifier filter, replaced more frequently. Installation is quick on both, with no disassembly beyond opening the filter compartment and swapping in the new piece.

Why we love it:

• Matches the AEH300's original 3-layer HEPA + carbon build — no compromise on filtration switching to replacement
• Activated carbon layer handles formaldehyde and toluene specifically, not just general odor
• Humidifier filter keeps the evaporative system mist-free and dust-free as designed
• Combo Pack matches real-world replacement rates — more humidifier filters, fewer HEPA
• Three purchase options — replace one system, the other, or both on the schedule each actually needs

Native Manor Note: The AEH300 does two jobs, and each one wears on its own timeline. This replacement lineup matches that reality — HEPA and carbon for the air, evaporative pads for the water, and a combo option sized to how the two actually wear. Keep the machine doing what it was bought to do, on the schedule it actually needs.
