The term “light box” can mean a few different things, but from a lighting perspective it typically refers to a backlit display panel. Light boxes are most commonly used for advertisements or other commercial displays. You’ve probably seen them in trade show booths, restaurants, airports, nightclubs, offices, hotels, museum exhibits, and retail shops. That’s right, light boxes are everywhere.

One of the most common uses for light boxes is the commercial advertisement. You see these in large spaces like terminals or outdoors at bus stops. They capture the attention of passers-by and create lasting impressions. The light box pictured below is one of the biggest I’ve ever seen.

One of the most obvious places you’ll see light boxes are along the walls inside and outside of movie theaters. Sometimes lines of light boxes stretch incredible distances, advertising all the movies being shown in large theaters.

In fact, light boxes can be a fun addition to any home and can be used for as many purposes as you can imagine. Sure, you could illuminate a movie poster of your daughter’s favorite movie. But you could also make a custom sign saying whatever you want. I really like the light box below, created at home for home.

Were you aware that the air quality inside your home can be worse than that of the outdoors? While this is especially prevalent in spring, fall isn’t exactly a walk in the park. The change of seasons kicks up many allergens and debris that can make even the healthiest person ill.

Before you think, “Well I change the air filter in my HVAC system on a regular basis, so isn’t that enough?” consider this: Your HVAC system’s air filter is there to protect the inside components of the system, not your indoor air.

So maybe you have an electronic air cleaner to take care of this problem. This type of air filter is incredibly beneficial. It works by removing microscopic impurities from your indoor air, such as dust, smoke, and smog, in addition to pet dander. Perhaps these seem like harmless particles to you—however, they can actually make you and your family ill.

Electronic air cleaners work best when you stay on top of cleaning the plates so that dirt doesn’t accumulate to a point that it becomes a problem. But if you have an electronic air cleaner, do you need a UV purifier?

While electronic air cleaners eliminate pollutants from the air, a UV air purifier kills certain contaminants within your ductwork before they even have a chance to enter the air. Most importantly, they eliminate microorganisms such as mold, mold spores, and other bacteria.

Microorganisms are not something that an electronic air cleaner can remove from the air. This doesn’t mean that electronic air cleaners are ineffective though—each type of air purifier eliminates the problem that the other one leaves. In other words, they work perfectly together for a comprehensive indoor air quality solution.
