Meaningful differences
What changes the fit
| What changes | AprilAire E070 Pro | AlorAir Sentinel HD55S WiFi | Why it matters |
|---|---|---|---|
| Design | Ductable whole-home cabinet | Compact crawl-space cabinet | This changes how the product performs its main task and how it fits into the user's routine. |
| Filter | Washable MERV 8 | MERV 1 supplied | This identifies what the treatment path is built to capture or reduce and what recurring care it requires. |
| Connectivity | Onboard or external control | Wi-Fi app | This affects connection compatibility and available data paths. A higher label does not guarantee the same real-world result in every setup. |
