# SonoHealth AirPro vs. Honeywell HPA300

> AirPro HEPA 14 vs. the Honeywell HPA300: filtration grade, UV-C, coverage, noise, and value compared so you can pick the right air purifier.

The main 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 Honeywell HPA300 is a proven **True HEPA (H13-class, 99.97% at 0.3 microns)** purifier with a strong fan but no UV-C stage. Honeywell is a trusted, widely available workhorse; the AirPro adds a higher filtration grade, UV-C, quiet 25 dB nights, and a 60-day trial at \$169.

## Filtration: HEPA 14 vs. True HEPA

The HPA300 uses a genuine **True HEPA** filter rated to **99.97% at 0.3 microns** (the H13 class). The AirPro's **HEPA 14** filter is certified to **99.995% at 0.3 microns** under EN 1822 — roughly **10× fewer particles** passing through at the hardest-to-trap size, plus capture of 99.9% down to 0.1 microns. For general dust, True HEPA is plenty; for smoke, ultrafine allergens, or sensitive households the higher grade matters. See [HEPA 14 vs. True HEPA](/air-purifier/hepa-14-vs-true-hepa).

## Noise and night use

Honeywell's HPA300 moves a lot of air but is noticeably louder on its higher settings. The AirPro is engineered for quiet operation, with a **25 dB Night Mode** and dimmed lights that suit bedrooms and nurseries. If you plan to run a purifier while you sleep, this is a meaningful difference.

## Where Honeywell leads

The HPA300 is backed by a long-standing brand, a **5-year limited warranty**, and very wide retail availability, and its powerful fan clears a mid-size room quickly. If you prefer a simple, no-frills True HEPA workhorse from a legacy brand, it's a solid pick.

## Which should you buy?

* **Choose the AirPro** for the higher HEPA 14 grade, built-in enclosed UV-C, quiet 25 dB nights, smart filter tracking, and a 60-day risk-free trial at \$169.
* **Choose the Honeywell HPA300** if you want a legacy-brand True HEPA unit with a strong fan and a long warranty, and don't need UV-C or an ultra-quiet night mode.

## Bottom line

The AirPro delivers **HEPA 14 filtration and enclosed UV-C at \$169**, a grade above the HPA300's True HEPA and with germicidal UV-C the Honeywell lacks. The HPA300 remains a dependable True HEPA choice with a long warranty. SonoHealth backs the AirPro with a 60-day free trial and is a Google Top Quality Store (sitewide 4.7 stars, 673 verified reviews).
