Febreze

I put one of these in a small guest bathroom that has no window, and it’s been killing the musty smell for weeks now. The scent boost adjustment on the cap is subtle but makes a real difference.

You can twist the top to adjust how much scent comes out, which I tested in my closet and settled on a low setting that lasted weeks. Perfect for a small, enclosed space.

I stuck one in my car's cup holder and another in the laundry room, and both spots have smelled fresh for over two weeks now.

My tiny powder room tends to hold onto odors, but placing one of these behind the toilet actually keeps it smelling fresh for weeks without overpowering. The lavender scent in this pack is surprisingly subtle and clean.

I had a musty smell in my bathroom closet that nothing else could touch, but after clipping one of these to the shelf, the whole space actually smells fresh and clean. The scent is strong enough to last a solid month without being overpowering.

I stuck one of these in my laundry room and the scent has been consistent for weeks now—surprised how long a tiny thing lasts. The variety pack is nice too, gives me different options depending on my mood.

The tiny dial on the bottom to adjust the scent intensity is genius—I set my bathroom one to low and it still kills any lingering odors. Been running for over a month now and I can still smell the fresh linen scent when I walk in.

I set these up in the laundry room and the bathroom, and they really do last more than a month each. The scent is noticeable but not overpowering, which is perfect for smaller spaces.

The vanilla scent is surprisingly subtle and doesn't clash with other fragrances in the room. I've had one tucked in the corner for three weeks now, and the bathroom still smells fresh every morning.

Tucked one behind the toilet and another near the sink — the scent is subtle enough not to be overpowering but still kills the damp towel smell. Lasts a solid month before I need to swap it out.
