# SonoHealth AirPro vs. Blueair Blue Pure

> AirPro HEPA 14 vs. Blueair Blue Pure purifiers: filter grade, UV-C vs. HEPASilent, coverage, noise, and value compared to help you choose.

The SonoHealth AirPro and Blueair's Blue Pure line are both quiet, capable purifiers, but they take different filtration approaches: the AirPro uses medical-grade **HEPA 14 (99.995% at 0.3 microns) plus fully enclosed, ozone-free UV-C**, while Blueair uses **HEPASilent**, a hybrid of mechanical filtration and electrostatic charging that Blueair rates highly for small particles and states is ozone-free. Blueair filters are not graded to the EN 1822 HEPA 14 standard and the Blue Pure line does not include UV-C.

## Filtration: HEPA 14 vs. HEPASilent

Blueair's **HEPASilent** combines a mechanical filter with an electrostatic charge, and Blueair reports strong capture of small particles at low noise. However, Blue Pure filters are **not certified to the EN 1822 HEPA 14 standard**, so the grade isn't directly comparable on paper. The AirPro's **HEPA 14** is independently defined at **99.995% at 0.3 microns** -- the same class used in hospitals and cleanrooms -- with activated carbon for odors and VOCs. If a verifiable, hospital-grade mechanical rating matters to you, the AirPro's HEPA 14 is the clearer spec. See [HEPA 14 Filtration](/air-purifier/hepa-14-filtration) and [HEPA 14 vs. True HEPA](/air-purifier/hepa-14-vs-true-hepa).

## Sterilization and ozone

The AirPro adds a **sealed UV-C lamp** (254 nm) that targets microorganisms captured on the filter, with no ozone and no user exposure. Blue Pure models rely on filtration alone and include **no UV-C**. Both are designed to be ozone-free: the AirPro has no ionizer, and Blueair states HEPASilent does not produce harmful ozone. For background on why ozone matters, see [HEPA vs. Ionizer Air Purifiers](/air-purifier/hepa-vs-ionizer-air-purifiers).

## Coverage and noise

Blue Pure coverage **varies widely by model** (roughly 200--540 sq ft), and the line is well known for very quiet operation. SonoHealth rates the AirPro at **430 sq ft in 10 minutes and up to 1,200 sq ft in 30 minutes**, with a **25 dB Night Mode**. Because coverage is published differently across brands and Blue Pure models, size to your actual room using [Room Coverage](/air-purifier/room-coverage) and [CADR vs. ACH Explained](/air-purifier/cadr-vs-ach-explained).

## Which should you buy?

* **Choose the AirPro** for a verifiable HEPA 14 grade, built-in ozone-free UV-C, large rated coverage in a single unit, a lifetime-warranty option, and a 60-day free trial.
* **Choose a Blueair Blue Pure** if you want an ultra-quiet, minimalist design and are comfortable with HEPASilent's electrostatic-plus-mechanical approach rather than a certified HEPA 14 grade.

## Bottom line

Both are quiet, capable, ozone-free-designed purifiers. The **AirPro leads on a certified HEPA 14 grade, added UV-C, single-unit coverage, warranty, and trial period at \$169**; **Blueair Blue Pure** shines on quiet, simple design with strong small-particle capture. SonoHealth is a Google Top Quality Store (sitewide 4.7 stars across 673 verified reviews).

The AirPro is a consumer wellness appliance that reduces airborne particles; it is not a medical device and does not treat any condition. Talk to a clinician about specific respiratory concerns.
