The details you need for the job.
Dimensions, installation guidance, and test information for compatible 14″ × 6″ return openings. Impeccable Air adds pre-filtration alongside the primary system filter; it does not replace it.
Dimensions.
| Duct opening | 14″ × 6″ |
|---|---|
| Exterior | 15.75″ × 7.75″ |
| Material | white ABS |
| Mounting | Three friction-fit clips (one top, two bottom); screws and anchors included. |
Airflow resistance.
An independent laboratory measured the pressure differential across a clean filter pad sealed in a laboratory duct fixture, at four duct airflows. That is a bench measurement of the pad — not of the assembled grille, a loaded filter, or any particular home. The figures will be published here once the tested pad is confirmed against the current production filter.
Filter loading varies by environment. Recommend regular inspection and replacement based on the filter’s condition.
Bench test, clean filter media, laboratory duct fixture. Resistance rises as a filter loads — inspection matters more than any single clean-media number.
Application limits.
Fits 14″ × 6″ return-duct openings
- 01
Returns only.
- 02
Wall mounting only — not evaluated or sold for ceiling use.
- 03
Fit requires an exact 14″ × 6″ return opening; other sizes are reviewed individually — never approved automatically.
- 04
The filter is activated-carbon pre-filtration — it supplements, never substitutes for, the system filter.
Understand the test conditions.
Replacement timing depends on how quickly the filter loads. Our field observations remain internal records, not published performance evidence. The particulate laboratory report is available to read; its results describe the tested configuration.
Review the methods and conditions when assessing the product for your application.
