How We Decided

In determining the best privacy window film to buy, we explored type, UV/light blocking ability (expressed as a %), application method, and aesthetics.

There are several different types of privacy window films, including decorative, blackout, and one-way window film. Decorative window film like our #1 pick Rabbitgoo 3D Decorative Privacy Window Film combines aesthetics (beautiful square pattern) and 95% of UV ray blocking, bringing in the best of both worlds.

Blackout film is designed for babies and deep sleepers and offers the most privacy, albeit at the expense of matching your room decor. Lastly, a one-way window film like the #3 pick WPCTEV Privacy Window Film offers a mirrored effect on the inside and total privacy facing in from the outside. This is for people who prefer to see what’s outside.

UV/light blocking ability is very important. Most of our recommended picks achieve 90%+ UV blocking, harmful sun rays. With prolonged exposure, UV rays could result in health defects, including melanoma and various skin cancers. These privacy window films also carry a thermal insulation effect, which helps reduce your energy bills.

The application method is key. We like static cling on a privacy window film that does not require any adhesives to install. Kudos for not leaving a messy residue. Our only knock is that it may be hard to apply from time to time, particularly with ensuring no tiny air bubbles from between the window and the film.

Aesthetics is also something we look at. From heavily neutral (blackout) to a cacophony of different colors, there are more than enough styles and patterns to choose from.
