If you are comparing the SonoHealth AirPro against a Shark air purifier, the short version is: the AirPro uses medical-grade HEPA 14 (99.995% at 0.3 microns) plus fully enclosed, ozone-free UV-C, starting at $169, while most Shark purifiers use True HEPA (H13-class) filtration with no UV-C. Shark’s pitch is easy setup and, on NeverChange models, a long-life filter; the AirPro’s edge is a higher filtration grade, added UV-C, and up to 1,200 sq ft of coverage.

Filtration: HEPA 14 vs. Shark’s True HEPA

Shark’s HEPA purifiers use a True HEPA (H13-class) filter, which captures roughly 99.97% of particles at 0.3 microns — genuinely good filtration. The AirPro is rated one grade higher to HEPA 14 (99.995% at 0.3 microns) under the EN 1822 standard, letting through about 10× fewer particles at the hardest-to-catch size, and it adds a UV-C stage Shark models don’t include. See HEPA 14 vs. True HEPA for what that gap means in practice.

​
What about Shark’s “NeverChange” filter?

Some Shark models advertise a long-life or “NeverChange” filter designed to last several years, which is convenient and lowers how often you handle a filter. The trade-off is that a very long-life filter still loads with particles over time, and you cannot swap in a fresh certified HEPA 14 element. The AirPro instead uses a replaceable HEPA 14 filter (6–12 months, tracked by the unit) so filtration stays at full grade — at 29.99–29.99–79.99, or 20% off with the filter subscription.

​
Where Shark wins

Shark is a strong mass-market choice: wide retail availability, simple controls, and on NeverChange models, years between filter changes. If you want a straightforward purifier from a familiar brand and True HEPA is enough for your needs, Shark is a reasonable pick.

​
Where the AirPro wins

The AirPro leads on filtration grade (HEPA 14), adds enclosed ozone-free UV-C, covers up to 1,200 sq ft, runs as low as 25 dB in Night Mode, and comes with a 60-day free trial and a 2-year warranty (lifetime with the filter subscription). Facts are grounded in the AirPro product page.
Neither purifier is a medical device, and neither treats or prevents any health condition. Both reduce airborne particles in the air passing through the unit; follow your clinician’s guidance for any respiratory concern.

​
Which should you buy?

  • Choose the AirPro if you want the highest filtration grade, built-in UV-C, quiet night operation, and a risk-free trial.
  • Choose a Shark if you prefer a familiar big-box brand and a long-life filter, and True HEPA (H13-class) meets your needs.
