# SonoHealth AirPro vs. Medify MA-40

> AirPro HEPA 14 vs. the Medify MA-40: filtration grade, UV-C, coverage, noise, and value compared so you can choose the right air purifier for your home.

The core difference is filtration grade and sterilization: the SonoHealth AirPro uses medical-grade **HEPA 14 (99.995% at 0.3 microns, EN 1822) plus fully enclosed UV-C**, while the Medify MA-40 is a well-reviewed **H13-class "True HEPA"** purifier (marketed at 99.9% at 0.3 microns) with a large touch panel but no UV-C stage. Both are strong mechanical purifiers; the AirPro sits one grade higher and adds germicidal UV-C at a lower entry price of \$169.

## Which one filters more thoroughly?

Both are genuine HEPA purifiers, but they sit one grade apart. The Medify MA-40 uses an **H13-class filter** marketed as capturing 99.9% of particles at 0.3 microns — the "True HEPA" tier. The AirPro's **HEPA 14** filter is certified to **99.995% at 0.3 microns** under EN 1822, so roughly **10× fewer particles** slip through at the most-penetrating particle size. For everyday dust the gap is small; for wildfire smoke, ultrafine allergen fragments, or an immunocompromised household it is the meaningful upgrade. See [HEPA 14 vs. True HEPA](/air-purifier/hepa-14-vs-true-hepa).

## 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 the filter traps them, sealed inside the unit with no user exposure and **no ozone**. The MA-40 relies on filtration alone. Learn how the AirPro's works in [UV-C Sterilization](/air-purifier/uv-c-sterilization).

## What about coverage and noise?

Medify publishes coverage using air-change rates, while SonoHealth publishes coverage as **area over time** (430 sq ft in 10 minutes; up to 1,200 sq ft in 30 minutes). Because the two use different yardsticks, match each to your room with [Room Coverage](/air-purifier/room-coverage) and [CADR vs. ACH Explained](/air-purifier/cadr-vs-ach-explained) rather than comparing headline numbers. On noise, the AirPro's 25 dB Night Mode is engineered for bedrooms and nurseries.

## Which should you buy?

* **Choose the AirPro** if you want the higher HEPA 14 grade, built-in enclosed UV-C, near-silent 25 dB night operation, and a 60-day risk-free trial at \$169.
* **Choose the Medify MA-40** if a large touch-panel display and its True HEPA filtration are enough for your space and you don't need UV-C.

## 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. The MA-40 is a capable True HEPA alternative. 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.
