Filtration Process

The Healthmate Plus has a 360-degree air intake that then moves the air through the 4-stage filtration process.

The Large Particle Pre-filter removes particles easily seen by the naked eye (e.g. dust, hair and pet dander). The Medium Particle Pre-filter removes small to medium size particles (e.g. molds, spores and pollen). Next, it moves the air over 780 cubic inches of Activated Carbon, Potassium Iodide Impregnated Carbon and Zeolite which helps remove Volatile Organic Compounds (VOCs), formaldehyde, benzenes, chemicals, gases and odors. The last stage is the True Medical Grade HEPA which removes 99.97% of all particles larger than 0.3 microns and 99% of all particles larger than 0.1 microns.The Healthmate Plus is a system equipped with the PERMA FILTER pre-filter and HEPA filter. The system also contains nearly 15 pounds of a chemical compound mixture. This mixture includes activated carbon and zeolite. The compound is also impregnated with potassium iodide. This chemical is known for its ability to absorb odors and chemical fumes from air and trap them. Once the air has been through the filtering system, the particles and contaminants are eliminated. The air is then passed through the chemical compound and the odors and fumes are eliminated.

Coverage and Real-World Use

Austin Air rates the HealthMate Plus for coverage up to 1,500 square feet at one air change per hour. For more frequent air cycling (about 2 ACH), it’s effectively targeted around 900 sq ft with 8-foot ceilings.

In everyday usage, the unit’s performance aligns with larger, high-capacity purifiers. It’s typically slower on particulate removal compared with high-CADR machines, but its VOC/gas results and odor removal are among the best in its category.

Noise and Day-to-Day Operation

Noise levels range from just under ~40 dB on low settings to around ~65 dB on high settings. That places it within typical conversation levels at higher speeds, and reasonably quiet for continuous use on low.

There is no air quality sensor, auto mode, sleep mode, or smart control. The control is a simple manual dial. For some users this will be a drawback; for others it reinforces the unit’s durable and straightforward approach.

Build Quality and Design

The HealthMate Plus features powder-coated steel housing and 360-degree intake grilles, giving it a solid and long-lasting feel. Casters included under the unit make repositioning easier despite its ~45-47 lb weight.

Maintenance and Filters

Filter Lifespan: Up to 3–5 years under normal residential usage.
HealthMate Plus replacement filters are more substantial and expensive than typical consumer units, but the up to 5-year life expectancy offsets long-term cost for many owners. There is no filter replacement indicator; maintenance is manual.

Pros and Cons

Pros

• Very strong VOC, odor, and chemical filtration
• True medical-grade HEPA for fine particulates
• Long-lasting filters with extended lifespans
• Coverage for larger rooms
• Durable steel construction
• 360° intake maximizes effective airflow

Cons

• Heavy and sizable compared with tower purifiers
• No smart features, sensors, or auto mode
• Higher upfront and filter replacement costs
• Manual controls only

FAQs

Final Verdict

The Austin Air HealthMate Plus excels when your priority is VOC and chemical removal combined with strong particulate filtration in larger spaces. It trades modern smart features for filtration depth, durability, and long-term value. It’s often recommended for chemical sensitivities, odor concerns, and environments with elevated VOC exposure, but may be over-engineered for basic dust/allergy needs.
