The Austin Air HealthMate® was designed to address your everyday air quality concerns. The Medical Grade HEPA technology is proven to remove up to 95% of all airborne contaminants as small as 0.1 microns. This includes viruses*, bacteria, dust, dander and allergens. The carbon blend used in this filter will also effectively remove chemicals, gases and odors. The Austin Air HealthMate® will significantly improve the quality of air in your home.

The HealthMate® is Austin’s original filtration unit. It is still our most popular unit as it addresses a wide variety air quality concerns by removing sub-micron particles, noxious gases and chemicals.

The Austin Air HealthMate® Filter is our originally designed filter that contains a blend of activated carbon and zeolite capable of absorbing chemicals, odors and gases as well as true medical grade HEPA (High Efficiency Particulate Arrestance). The HEPA in this filter traps 99.97% of all particles down to 0.3 microns in size. Today this is still our most popular unit as it addresses the most general of indoor air quality concerns.

The NuWave OxyPure Smart Air Purifier Is Calculated to Remove 99.999% of Airborne Porcine Respiratory Coronavirus in Areas up to 1,200 Square Feet in 6 Hours!*

Revolutionary 5-Filter System:

  • The Stainless Steel Pre-Filter, which is also washable and reusable for up to 20 years captures larger particles, pollutants, and allergens such as pollen, pet hair, and dander.
  • The OxyPure™’s Bio-Guard Filter uses Electrostatic Precipitation (ESP), which is washable and reusable for up to 20 years, captures and traps 100% of particle pollutants as small as 0.09 microns. No other air purifier on the market captures 100% of particle pollutants down to sizes of 0.09 microns, as well as eliminates 99.99% of bacteria, 99.96% viruses, and molds!
  • The Ozone Emission Removal Filter, with a 20-year lifespan, eliminates harmful ozone gas (O3) from the home to less than 1 ppb – 70 times less than the EPA’s household standards of 70 ppb.
  • 2-in-1 HEPA/CARBON FILTER - Most HEPA filters are good against particle pollutants, but the OxyPure's combination HEPA/Carbon Filter not only traps particles and allergens such as pollen, dust mites, molds and spores; it also traps industrial, household, and vehicle fumes and emissions; VOCs such as formaldehyde, benzene and other cleaning chemicals; and household and cooking odors.

Other Features:

  • 360-Degree Air Intake
  • 6 Fan Speeds
  • 6 Air Quality Levels
  • Six Odor Levels of Detection
  • Eco-Friendly Mode
  • Sleep Mode
  • Wi-Fi-Enabled (Track, monitor and operate the OxyPure through an APP.)
  • Ultimate Clean (Automatically adjusts based on air quality.)
  • 2 Certifications (California's CARB and EPA's Energy Star)

OxyPure Test and Performance Data:

  • Air Purifier Efficiency Test – Coronavirus by University of Minnesota Particle Calibration Lab
    • The University of Minnesota tested the OxyPure’s removal rate for coronaviruses using the porcine respiratory coronavirus and calculated it to remove up to 99.999% of the virus in just 6 hours.*
  • Air Purifier Efficiency Test - Pathogens by Intertek Testing Services
    • The test focused on the removal rates for airborne pathogens, specifically the H3N2 Influenza virus (99.96%)
  • Air Purifier Efficiency Test - Escherichia Coli by Intertek Testing Services
    • This test focused on the removal rate for the following: E. coli bacteria (99.99%), Staphylococcus Albus bacteria (99.99%), Staphylococcus Aureus bacteria (99.99%), and Aspergillus Niger bacteria (99.99%). Intertek found that after 2 hours, the OxyPure removed an average of 99.99% of the pathogen.
  • Air Purifier Efficiency Test - Smoke, Dust, And Pollen by Intertek Testing Services
    • Using Tobacco Smoke (particle size: 0.10 - 1.0 microns), AC Fine Test Dust (particle size: 0.5 - 3.0 microns), and Paper Mulberry Pollen (particle size: 5 - 11 microns), the tests showed an average Clean Air Delivery Rate (FT3/Min) of 354.9 for Smoke, 332.8 for Dust, and 362.6 for Pollen.
  • Air Purifier Efficiency Test – Anions by Intertek Testing Services
    • In addition to producing no ozone, the OxyPure also produces no extraneous negative ions (anions). The Bio-Guard Filter creates anions as part of its normal function. However, like the pathogens and particles trapped by the Bio-Guard Filter, the anions it generates also remain in the filter.
  • Air Purifier Efficiency Test – CADR For Smoke, Dust, And Pollen by Intertek Testing Services
    • Intertek Labs tests are based on the Clean Air Delivery Rates (F3/Min.) for Tobacco Smoke (particle size: 0.10 - 1.0 microns), AC Fine Test Dust (particle size: 0.5 - 3.0 microns), and Paper Mulberry Pollen (particle size: 5 - 11 microns), the tests showed an average Clean Air Delivery Rate (FT3/Min) of 354.9 for Smoke, 332.8 for Dust, and 362.6 for Pollen.
  • Air Purifier Efficiency Test - Formaldehyde Intertek Testing Services
    • Intertek tested the OxyPure’s formaldehyde removal rate. The test shows that at 110 minutes, the removal rate is 95.1%!
  • Air Purifier Efficiency Test - Ozone Emission by Intertek Testing Services
    • Ground level ozone concentrations (measured in parts per billion or ppb) varies depending on where you live. You can live in places where it is fairly low, like Oahu in Hawaii, which averages 49ppb1; or in places like Chicago, which averages 72ppb2. The national average hovers around 70ppb3, which is also the current EPA standard. The CARB-Certified OxyPure's Ozone filter drops the ozone concentration in your home to 1ppb, 70 times lower than current EPA limits and well below the ozone concentration you would find outside anywhere in the U.S.

The NuWave OxyPure™ Smart Air Purifier includes a 5-year limited warranty by the purifier manufacturer. (The warranty is between the purchaser of the purifier and the NuWave manufacturer.)

MAC HEPA filters installed in new or existing supply, exhaust or return duct systems are efficient to 99.97% at 0.03 micrometers as standardized by the CDC and NIH in the Biosafety in Microbiological and Biomedical Laboratories (BMBL). The MAC filter line is manufactured to these standards.

The filters are available with 8", 12" and 16" flanges depending upon the size of the filter in CFM's.

The lifespan of the MAC filter is between 5-7 years depending upon the environment of filtered air.
