Product Description

Restore your Austin Air purifier to full performance with the HealthMate Plus Replacement Filter — a complete 4-stage, medical-grade cartridge built for the toughest chemical, smoke, and odor loads. It pairs 60 sq. ft. of True Medical Grade HEPA with up to 15 lbs of activated carbon, potassium iodide impregnated carbon, and mineral-based media to capture fine particles and neutralize VOCs, formaldehyde, wildfire smoke, and strong odors. Handcrafted in Buffalo, NY.

Key Features

  • True Medical Grade HEPA (60 sq. ft.) — captures 99.97% of airborne particles down to 0.3 microns and 99% down to 0.1 microns, including smoke, dust, pollen, mold spores, bacteria, and viruses.
  • Enhanced carbon blend (up to 15 lbs) — activated carbon, potassium iodide impregnated carbon, and mineral/zeolite media remove formaldehyde, benzene, and other toxic chemicals from wildfire smoke, paint fumes, and building materials.
  • Complete 4-stage cartridge — includes both pre-filters, the full carbon bed, and the HEPA in one drop-in replacement.
  • Designed to last up to 5 years under normal residential use (sooner in high-pollution or pet-heavy homes).
  • Prefilter color to match your unit — choose White for White or Sandstone purifiers, Black for Black or Midnight Blue purifiers.
  • Backed by a 5-year warranty and a 30-day risk-free trial; handcrafted in Buffalo, NY.

4-Stage Filtration

  • Stage 1 — Large-particle pre-filter: hair, dust, and visible debris.
  • Stage 2 — Medium-particle filter: pollen, mold spores, and smaller dust.
  • Stage 3 — Carbon & mineral blend: up to 15 lbs of activated carbon, potassium iodide impregnated carbon, and mineral media for gases, chemicals, VOCs, and odors.
  • Stage 4 — True Medical Grade HEPA: 60 sq. ft. for fine particles, smoke, and allergens.
