How to choose

Finding the right fit

Three things decide which purifier is right for you.

Start with your trigger

Chemicals and smoke need heavy activated carbon; allergies and dust need true HEPA. Most of our units do both.

Match it to your space

Coverage is rated in square feet. Size up if you want more air changes per hour in a larger room.

Filtration first, no ozone

No ozone generators and no ionizers. Where a model has a UV-C lamp, it is sealed inside the cabinet and its page says so.

What people say after the first week

Two wildfire seasons and still performing

I live in fire-risk country and needed something compact for my 380 sq ft bedroom that could run on high during smoke events. The 'it' at speed 4 keeps indoor particle levels low during fires and drops to speed 2 for normal operation. Two wildfire seasons through. Performs exactly as expected. For bedroom-sized protection in a fire-prone area, this is the correct unit.

Impregnated carbon for mold-related VOCs — specific choice

We discovered mold after water damage. Post-remediation, I needed something for both residual spores and the VOCs from the remediation process. The V600's impregnated carbon specifically targets the VOC classes associated with mold off-gassing, and the True HEPA handles the spore class. Six months post-remediation, air quality testing came back clean. The V600 has run continuously since.

Gateway to the Austin Air lineup

Started with the 'it' for my bedroom. Loved the results enough to buy a standard HealthMate for the living room and a Junior for my daughter's room. The entry-level unit introduced me to what real air filtration feels like — no plastic smell, no ozone, consistent performance. Now I'm all-in on Austin Air. The 'it' is still running perfectly at 14 months on speed 2 in my bedroom.

Eight wildfire smoke days handled easily

During last fall's fire events, I ran the Junior at speed 4 for 8 consecutive days while outdoor AQI was hazardous. My indoor monitor never read above 22 during that period. The HEPA stage on smoke particles is very effective. Now running at speed 2 for normal operation. This is essential equipment if you live in fire-risk areas and don't need the coverage of the full HealthMate.

Solid entry level — know what it's built for

The 'it' is a genuine air purifier for spaces up to 500 sq ft. It doesn't cover 1,500 sq ft — it's not supposed to. For a bedroom, office, or small apartment, it's the right tool. Real HEPA, real carbon. Speed 4 is loud but you'd only run that during a smoke event. Speeds 1–2 are quiet enough for sleep. Good product, just size it to the right application.
