- What does H13 True HEPA actually filter?
- H13 is a high-grade HEPA class that captures at least 99.95% of particles around 0.3 microns, including pollen, dust and most pet dander. It does not remove gases or odors on its own.
- Is 857 sq ft enough for my room?
- That rating usually assumes one air change per hour at top fan speed. For allergy relief, treat roughly half that area as the realistic comfortable size, or about 400 to 450 sq ft.
- Does it remove smoke and cooking smells?
- Only if a carbon or activated-charcoal stage is included. The listed specs show HEPA filtration alone, which traps particles but not odor molecules.
- How often do I replace the filter?
- Most HEPA filters last six to twelve months depending on use and dust levels. Running it at top speed constantly shortens that.
- How loud is it at high speed?
- Large-room purifiers typically run noticeably louder on maximum. Expect a low hum on low and a fan-like rush on high, which is why many people run them overnight on a lower setting.
- Does it have an auto mode or app control?
- Nothing in the listed specs mentions a sensor, auto mode or app. Assume manual fan-speed control unless the full listing says otherwise.
