The biggest difference is filtration grade and sterilization: the SonoHealth AirPro uses medical-grade **HEPA 14 (99.995% at 0.3 microns) plus fully enclosed UV-C**, while the Levoit Core 400S uses a **True HEPA (H13-class, 99.97%)** filter with no UV-C. The Levoit adds Wi-Fi, an air-quality sensor, and auto mode; the AirPro leads on filtration grade, quiet operation, and its 60-day trial. ## Quick comparison | Feature | **SonoHealth AirPro** | Levoit Core 400S | | ---------------------- | --------------------------------------------------------------------------- | ------------------------------------------------------- | | **Filter grade** | HEPA 14 (99.995% at 0.3 µm) | True HEPA, H13-class (99.97% at 0.3 µm) | | **UV-C sterilization** | Yes (fully enclosed, 254 nm) | No | | **Filtration stages** | 3-stage + UV-C | 3-stage (pre-filter + HEPA + carbon) | | **Coverage** | 430 sq ft / 10 min; up to 1,200 sq ft / 30 min | \~403 sq ft at 5 air changes/hour (larger at lower ACH) | | **Noise** | 25--50 dB (Night Mode 25 dB) | \~24--52 dB | | **Smart features** | Lifetime filter tracker, Smart Timer, Night Mode, aromatherapy, 360° intake | Wi-Fi app, auto mode, air-quality sensor, display | | **Ozone** | None (no ionizer) | None (no ionizer) | | **Warranty** | 2-year (lifetime with filter subscription) | 2-year (typical) | | **Trial** | 60-day free trial | Retailer-dependent | | **Price** | \$169 | Typically \~\$220 | ## Which filters more thoroughly? Both are strong mechanical purifiers, but they sit one grade apart. The Levoit Core 400S uses a **True HEPA** filter rated to **99.97% at 0.3 microns** (the H13 class). The AirPro's **HEPA 14** filter is rated to **99.995% at 0.3 microns** under the EN 1822 standard — roughly **10× fewer particles** slip through at the most-penetrating particle size. For most healthy households, True HEPA is more than adequate. If you are buying specifically for allergies, asthma, wildfire smoke, or an immunocompromised family member, the higher HEPA 14 grade plus UV-C is the meaningful upgrade. See [HEPA 14 vs. True HEPA](/air-purifier/hepa-14-vs-true-hepa) for the full breakdown. ## Does UV-C matter here? This is the clearest functional gap. The AirPro adds a **fully enclosed UV-C (254 nm)** stage that targets bacteria and mold after they are trapped by the filter; the Core 400S has **no UV-C**. The AirPro's UV-C is sealed inside the unit, so there is no user exposure and **no ozone**. Learn how it works in [UV-C Sterilization](/air-purifier/uv-c-sterilization). No air purifier "cures" or prevents illness. UV-C and HEPA filtration reduce airborne particles and microorganisms in the air that passes through the unit; they are not a substitute for medical care, vaccination, or ventilation. ## What about smart features and coverage? Here the **Levoit leads**. The Core 400S includes a Wi-Fi app, an air-quality sensor, and an **auto mode** that adjusts fan speed to real-time readings — genuinely convenient if you want a hands-off purifier. The AirPro takes a simpler approach: manual fan speeds, a 2/4/6-hour Smart Timer, a 25 dB Night Mode, and a lifetime filter tracker, with **no app required**. On coverage, the two are rated differently. Levoit publishes a **CADR (260 CFM)** and a room size at a specific air-change rate (\~403 sq ft at 5 ACH). SonoHealth publishes coverage as **area over time** (430 sq ft in 10 minutes; up to 1,200 sq ft in 30 minutes at fewer air changes). Because the two use different yardsticks, match each to your room using [Room Coverage](/air-purifier/room-coverage) and [CADR vs. ACH Explained](/air-purifier/cadr-vs-ach-explained) rather than comparing the headline numbers directly. ## Which should you buy? * **Choose the AirPro** if you want the highest consumer filtration grade (HEPA 14), built-in UV-C, near-silent 25 dB night operation, and a 60-day risk-free trial at a lower price. * **Choose the Levoit Core 400S** if app control, an air-quality sensor, and automatic fan adjustment are must-haves and True HEPA is sufficient for your needs. Both avoid ozone, so neither carries the [ionizer ozone concern](/air-purifier/hepa-vs-ionizer-air-purifiers). ## Bottom line For allergy, asthma, smoke, and mold-focused buyers who want the strongest filtration and sterilization for the price, the **AirPro's HEPA 14 + UV-C at \$169** is the stronger value. For smart-home users who prioritize sensors and app automation, the **Levoit Core 400S** is a fine True HEPA choice. SonoHealth is a Google Top Quality Store (sitewide 4.7 stars across 673 verified reviews) and backs the AirPro with a 60-day free trial. *** **Related:** [AirPro vs. Coway](/air-purifier/airpro-vs-coway) · [AirPro vs. Dyson](/air-purifier/airpro-vs-dyson) · [Best HEPA 14 Air Purifier](/air-purifier/best-hepa-14-air-purifier) · [AirPro vs. Competitors](/air-purifier/vs-competitors) · [Buy AirPro](/air-purifier/buy)
