The Austin Air Immunity Machine is powered by an 8-phase filtration system—the most comprehensive air cleaning technology available today. Each stage is designed to target a specific class of pollutants, working together to deliver unparalleled protection for your immune system. It starts with our large and medium particle prefilters, which trap visible contaminants like dust, hair, pet dander, mold spores, and pollen. By capturing these irritants early, the Immunity Machine keeps your air cleaner while extending the life of the deeper filtration layers.

In the next phases, the Immunity Machine goes beyond ordinary purifiers with a combination of activated carbon, potassium iodide-impregnated carbon, zeolite, and proprietary-impregnated zeolite. This unique mix of media adsorbs odors, smoke, and everyday household gases, while also neutralizing hazardous pollutants like VOCs, formaldehyde, ammonia, and nitrogen dioxide. No other air purifier combines all four—making this system a powerhouse against the chemical and gaseous toxins that most threaten human health.

Finally, the Immunity Machine delivers medical-grade protection with true HEPA and HEGA filtration. The medical-grade HEPA removes 99.97% of particles down to 0.3 microns and 99% of particles down to 0.1 microns—including viruses, bacteria, and microplastics. The final barrier, our HEGA carbon cloth, is a military-grade material originally developed to protect against chemical, biological, and radioactive agents. Together, these final stages provide unmatched defense, ensuring you and your family breathe the cleanest, healthiest air possible.

The Austin Air Immunity Machine uses an 8-phase filtration system that’s more comprehensive than any other air purifier on the market. Each phase targets a specific class of pollutants, working together to provide maximum protection for your health and immune system.

Phase 1: Large Particle Prefilter – First Defense Barrier

Captures visible pollutants like dust, pet hair, and dander. This keeps your air cleaner from the start and helps extend the life of the deeper filters.

Phase 2: Medium Particle Prefilter – Precision Particle Catcher

Removes smaller irritants like mold spores and pollen that often trigger allergies, especially in children and sensitive individuals.

Phase 3: Activated Carbon – Odor & Gas Adsorber

Eliminates common household odors from pets, cooking, and smoke, while also removing everyday gases and chemicals.

Phase 4: Potassium Iodide-Impregnated Carbon – Advanced Chemical Component

Neutralizes hazardous chemicals such as VOCs and formaldehyde, along with toxins from building materials, cleaners, and wildfire smoke.

Phase 5: Zeolite – Dedicated Detox Agent

Targets and removes gases like ammonia that standard carbon filters can’t capture on their own.

Phase 6: Proprietary-Impregnated Zeolite – Enhanced Gas Neutralizer

Binds to nitrogen-based gases, including Nitrogen Dioxide (NO2) from gas appliances and smog, as well as other difficult-to-remove pollutants.

Phase 7: Medical-Grade HEPA – Particle Protection

Removes 99.97% of airborne particles as small as 0.3 microns and 99% down to 0.1 microns—including viruses, bacteria, allergens, and microplastics.

Phase 8: HEGA (High-Efficiency Gas Adsorption) – Military-Strength Protection

Uses military-grade HEGA carbon cloth—originally designed to guard against chemical, biological, radioactive, and nuclear agents—to remove the most dangerous gases, ultra-fine particles, and biological threats.

Together, these eight layers create the most advanced air purifier available, delivering unmatched protection against allergens, chemicals, gases, and pathogens so you can breathe the cleanest, healthiest air possible.

While both the Austin Air Immunity Machine and the Austin Air Bedroom Machine deliver exceptional clean air performance, the key difference lies in the filtration media. The Immunity Machine includes not only carbon and zeolite, but also impregnated carbon and impregnated zeolite—advanced filtration materials that the Bedroom Machine does not use.

This matters because impregnated carbon is specially treated to neutralize tough chemical pollutants like formaldehyde, VOCs, and other toxic byproducts from wildfire smoke, cleaning products, and building materials. Similarly, impregnated zeolite is enhanced to capture nitrogen-based gases, such as nitrogen dioxide (NO₂) from gas appliances and vehicle emissions, as well as ammonia and other harmful compounds.

By combining four layers of granular adsorption media instead of just two, the Immunity Machine provides a more robust defense against the widest range of chemicals, gases, and VOCs. If your main concern is immune health, environmental toxins, or protection from chemical pollutants, the Immunity Machine offers a higher level of protection than the Bedroom Machine—making it the most comprehensive air purifier available today.

It’s even better! A "whole house air cleaner" is typically integrated into the home's HVAC (Heating, Ventilation, and Air Conditioning) system, but portable air cleaners by Austin Air are the best air filters for home and here’s why:

• Cost-Effective: Austin Air cleaners are less expensive upfront compared to whole home systems. This makes them a more accessible option, in addition to being the best home air purifier.
• 24/7 Use: We recommend running our units 24/7 but no matter what you choose, you are in control unlike whole house systems which only work when the heating or cooling are active.
• Immediate Benefits: Austin Air filters in the house provide immediate relief from poor air quality in the specific area where they are used. They can start working right away to improve air quality and comfort.
• Customizable Coverage: You can choose different models and sizes of Austin Air cleaners – Standard, Junior, or the “it” personal air purifier – based on the specific needs of each room. This allows you to customize the level of air purification according to the room’s size and air quality requirements.
• Targeted Air Cleaning: Portable air cleaners can be placed in specific rooms or areas where air quality is a concern, allowing for more focused and effective cleaning of the air where it’s needed most.
• Flexibility and Portability: Portable units can be moved from room to room as needed, which is especially useful if different areas of your home have varying air quality issues or if you want to address different rooms at different times. For one example: this is a game changer for home cooks with kitchens that are prone to setting off the smoke alarm. 
• Ease of Maintenance: Maintenance for portable Austin Air cleaners is simpler and less costly because filters last for five years. Filter replacements and cleaning can be done by the user, without the need for a professional.
• No Installation Required: Austin Air cleaners are plug-and-play, meaning you can start using them right away without professional installation, which saves time and money. 

In other words: a portable air cleaner by Austin Air is the best air filter for home and work.
