# SonoHealth AirPro vs. GermGuardian

> AirPro HEPA 14 vs. GermGuardian tower air purifiers: filtration grade, UV-C, room coverage, ozone, warranty, and price compared to help you choose.

The AirPro is a higher-grade, larger-coverage purifier: medical-grade **HEPA 14 (99.995% at 0.3 microns, EN 1822) with fully enclosed, ozone-free UV-C** and up to **1,200 sq ft** coverage for **\$169**. Most GermGuardian towers are budget **True HEPA (H13-class, \~99.97%)** units for small rooms, often with an optional UV-C/ionizer stage. Choose the AirPro for filtration grade, coverage, and enclosed UV-C; choose GermGuardian for the lowest upfront price in a small space.

## Filtration grade: HEPA 14 vs. True HEPA

GermGuardian's HEPA towers use **True HEPA (H13-class)** filters marketed around 99.97% at 0.3 microns. The AirPro is rated to the higher **HEPA 14** grade — **99.995% at 0.3 microns under EN 1822** — capturing roughly 10x fewer particles at the hardest-to-trap size, and 99.9% down to 0.1 microns. If filtration grade is your priority, the AirPro sits a full class above. See [HEPA 14 vs. True HEPA](/air-purifier/hepa-14-vs-true-hepa).

## Room coverage: small room vs. whole living space

Most GermGuardian towers are sized for a **single small room** (roughly 150-190 sq ft by AHAM room-size ratings). The AirPro cleans **430 sq ft in about 10 minutes** and up to **1,200 sq ft in 30 minutes** with 360-degree intake, so one unit covers a living room, open-plan space, or large bedroom. Match coverage to your room in [Room Coverage](/air-purifier/room-coverage).

## UV-C and ozone

The AirPro includes a **fully enclosed UV-C (254 nm)** stage as standard, with **no ozone** because there's no ionizer. Some GermGuardian models add UV-C, and a few pair it with an ionizer or PCO stage — if you want to avoid any ozone-generating technology, check the specific model. The AirPro keeps it simple: mechanical HEPA 14 + carbon + enclosed UV-C, ozone-free. See [UV-C Sterilization](/air-purifier/uv-c-sterilization) and [HEPA vs. Ionizer](/air-purifier/hepa-vs-ionizer-air-purifiers).

## Which should you buy?

* **Choose the AirPro** if you want medical-grade HEPA 14, enclosed ozone-free UV-C, whole-room coverage up to 1,200 sq ft, and a 60-day trial.
* **Choose a GermGuardian tower** if you need the lowest upfront price for a single small room and True HEPA is enough for your needs.

## Bottom line

For allergy, asthma, smoke, and mold buyers who want the highest consumer filtration grade and coverage for a whole room, the **AirPro's HEPA 14 + enclosed UV-C at \$169** outclasses a typical budget GermGuardian tower. If your only goal is the cheapest True HEPA unit for one small room, GermGuardian competes on price. SonoHealth backs the AirPro with a 60-day free trial and is a Google Top Quality Store (sitewide 4.7 stars, 673 verified reviews — a store-wide figure, not a per-product rating).
