The 3M BPTAP003 Bright Screen Privacy Filter limits side viewing on Apple iPad 11-inch models (1st–4th generation) and iPad Air 10.9-inch models (4th–5th generation). Its 3M ID is 7100311651.
Using 3M Nanolouver technology, it restricts side viewing outside a 60-degree viewing angle. 3M states that the filter transmits an average of 85% of the device’s brightness and helps reduce blue light without distorting natural display color.
The reversible filter has glossy and matte sides. According to 3M, both finishes help reduce glare and fingerprints, letting you choose the screen appearance that suits you on the listed iPad models.
