Public health experts have repeatedly stressed the importance of having a quality face mask to protect you from COVID-19, with the Centers for Disease Control and Prevention urging people to wear a well-fitting, multi-layered mask. That's important now more than ever.

"Now is not the time to relax the critical safeguards that we know can stop the spread of COVID-19 in our communities, not when we are so close," CDC director Rochelle Walensky recently said during a press conference. In addition to picking a snug-fitting mask, the CDC said in guidance issued in February that a quality mask is one "with layers to keep your respiratory droplets in and others’ out."

If you already have a mask you love but want to upgrade it, there's a solution: Add a filter—but not just any filter. PM 2.5 activated carbon filters are considered the gold standard. These filters contain five layers, including an active carbon sheet, to help filter out airborne particles.

And, right now, Amazon is holding a sale on its best-selling JCBABA PM 2.5 filters. Currently, you can snag a 20-pack for just $9 (was $11).

The filters are a quick and easy way to upgrade your existing mask or make a new mask you're considering even more efficient. Just slip them into your mask's filter pocket and—voila!—more protection.

The filters are washable and reusable, and it's recommended that you swap yours out for a new one every week.

These filters have an army of fans who swear by their quality. One five-star reviewer even ripped a filter apart to verify that it had five layers. "The size fits perfectly in my cloth masks," a happy customer wrote. Another fan said they "work great!" in their cloth face masks, pointing out that they tried the "flame test" to try to blow out a candle while wearing the filter. "I couldn’t blow it out with this filter in place," they said.

Another five-star reviewer said the filters actually make their cloth face mask more comfortable. "It has a little stiffness to it that actually holds the cloth mask away just enough so you can breath better," they said. "It does not stick to your mouth so it is easier to speak."
