Febreze Small Spaces Luftfräschare Heavy Duty Fresh Lemon, 25 fl. oz, 4-pack

The 45-day freshness claim actually holds up—I put one behind the toilet and forgot about it until I caught the lemon scent wafting out weeks later. Heavy Duty isn't just marketing hype; it cuts through musty air way faster than the regular version. Already ordered another pack.

My bathroom finally smells like real lemons instead of just covering up odors. The heavy-duty formula makes a noticeable difference, and these little discs actually last the full 45 days like they claim.

I was skeptical about the 45-day lifespan claim, but this little thing has been pumping out fresh lemon in my laundry room for over a month now without fading. The pack of four is perfect for stashing one in each bathroom.
