When considering the most important feature in any room, windows are definitely near the top of the list. They provide a look out into the world, keeping us connected to nature, helping reduce stress and regulating our biological clocks. At Apartment Therapy, we love a good window; that’s why we have articles on how to dress one up and the best blackout curtains for every season. But just as often, windows can offer outsiders a look into our homes, disrupting the sense of privacy we value so much. Fortunately, Amazon has a solution — I mean, when does it not? For just $12, the Coavas window privacy film promises to keep potential snoopers away, which can be especially helpful when living in close proximity to neighbors or in a high-volume neighborhood.

Although I typically feel safe at home, my affinity for true crime podcasts and general reality as a woman can sometimes stir feelings of paranoia over the possibility of someone getting access to my most private spaces. Other Amazon shoppers share this sentiment and credit the window privacy film with alleviating some of these fears. “Had some windows at the front door that were completely see-through and needed to cover it up so I could avoid being surprised by whatever’s on the other side of the door,” a customer wrote. “I’ve always had a fear that one day I would walk by the front door and someone would be peering through the clear windows into the house.” Relatable, am I right, ladies?

In all seriousness though, the window privacy film is good for a multitude of things. For one, those who have a more minimal home decor style will enjoy this product because it removes the need for blinds and curtains. I must admit, although I haven’t personally tried this film, the mere thought of not having to dust my blinds is tempting me to press “add to cart.” Even pets seem to experience a more peaceful existence with the addition of this home feature. “We have two long windows framing our front door, and we wanted to add the film so that our dogs don’t bark by everyone walking down the street,” one customer shared. More tempting still.

The film also guarantees complete glare removal, as well as “heat insulation in the summer and heat preservation in the winter.” Those who bought it praise its easy application and removability in addition to its subtle appearance. “It’s thick and does a nice job allowing light to filter through with a nice white glow,” one reviewer wrote. Available in 15 different dimensions, the UV-blocking film is fit for a multitude of window sizes. To apply, wet your window with water, place the film on top, making sure to scrape out any bubbles, and dry the surface.

All in all, I can appreciate any product that makes a home feel safer and more economical without sacrificing visual appeal. It appears this privacy film does all of that, and for an unbelievably low cost.
