Overview and Features

Whether you have dogs or cats, pets leave behind an odor that’s unmistakable. This is often due to their pet dander, which can float in the air for several hours. But finding an air purifier that can trap micro-sized particles of pet dander can be a real challenge.

How to keep home clean with pets isn’t easy, but if you have the right air purifier, you can keep your house smelling fresh around the clock.

These days, most air purifiers that you’ll run into are only designed for bedroom use. And while that’s definitely a bonus if you need a powerful air purifier that can purify the air while you sleep, others are looking for a model that can handle larger spaces in the home, working to efficiently purify the air, eliminating pet odors and dander.

Inside the filter, the glass fibers are carefully arranged in order to capture dust, pet dander, mold, and other large particles, allowing clean air to pass through.

Thanks to this unique design, up to 99.9 percent of contaminants are trapped inside the filter. The filter’s powerful design will majorly impact the air quality in your home.

Coverage Size
