In recent months, a curious trend has been gaining attention online and in everyday households: people hanging face masks in front of electric fans. At first glance, it may seem strange or even pointless — but there’s actually a clever reason behind it. And once you understand the trick, you might want to try it too.

A DIY Air Freshener and Humidifier in One

The main idea behind hanging a face mask in front of a fan is to transform it into a simple, low-cost air freshener or mild humidifier. Here’s how it works:

People lightly spray the mask with essential oils, floral water, or even diluted vinegar or herbal solutions. When the fan is turned on, the airflow passes through the mask, diffusing a gentle scent throughout the room. If the mask is slightly damp, it can also add a bit of moisture to the air — ideal for those hot, dry summer days.

Why It Works

The fabric of a face mask holds scents well and allows air to pass through easily. When suspended in front of a fan (not covering the fan), it acts like a scented filter. Unlike some commercial air fresheners, this method is natural, customizable, and eco-friendly.

Some users add a few drops of lavender or peppermint oil to promote relaxation or alertness, depending on the time of day. Others use lemon or eucalyptus for a refreshing feel. The method is especially popular among people sensitive to synthetic fragrances.

My Experience

Curious about the trend, I gave it a try — soaking a clean disposable mask in diluted rose water and hanging it a few inches in front of my standing fan. Within minutes, the room filled with a subtle floral scent. It wasn’t overpowering, but enough to create a fresh and pleasant atmosphere. I didn’t expect much at first, but the result was truly surprising: a soothing, spa-like vibe using items I already had at home.

A Few Tips

• Don’t oversaturate the mask — it should be damp, not dripping wet.

• Use natural, skin-safe liquids if the fan is in a bedroom or near children.

• Replace or re-spray the mask daily to avoid bacteria buildup.

• Avoid blocking the fan’s airflow completely — the mask should be hung loosely in front, not pressed against the fan.
