Austin Air developed the Pet Machine™ air purifier to remove the allergens caused by pets. This filter uses HEPA technology to trap airborne dust and dander, while its special carbon blend helps reduce many pet odors that linger in the air. Every minute, over 250 cubic feet of air passes through 15 pounds of Activated Carbon and over 60 square feet of True Medical Grade HEPA, providing air so clean it could change your life and how you sleep. If it doesn’t, Austin Air will refund your money within 30 days. NOTE: due to increased demand for Austin Air’s medical grade air purifiers, production of Pet Machine units has been suspended, though replacement filters are still available.

The Pet Machine™ addresses the complete spectrum of air cleaning, removing sub-micron particles, noxious gases and chemicals. Austin Air’s 360-degree intake system draws air into all sides of The Pet Machine™, passing it through a 4-stage filter. The result: more clean air delivered faster and more efficiently than any other air cleaner on the market.

When to replace your Austin Air filter

Austin Air filters are designed to last up to five years under normal residential use. Many air purifiers on the market today come with an indicator that tells you when to replace the filter. These devices provide only a measurement of time, not a true indication that the media is exhausted. Media life depends on many other factors: how many hours the filter is run per day, the fan speed typically used, which pollutants are being removed, the quantity of pollutants in the air, and more. The easiest way to know when it’s time to replace an Austin Air filter is to watch for a change in smell when it’s running; normally a sweet or sour smell, or an ammonia or vinegar odor, indicates the unit needs a replacement filter.
