I didn't expect this little cone shaped air freshener to smell up my whole house but I had a little higher expectation. I bought 4 of these and use them over the course of a couple months, one at a time. At 1st I put 1 in a living room that is approximately 20' by 15'. You could smell the freshener if you were with in approximately a 5' radius after that there was no smell detected. I used the 2nd one in my bathroom. That Room is approximately 7' by 10'. That Room I could smell it perfectly when walking in and it lasted about a month with a nice scent. I used another 1 in my kitchen and really could not smell it until I put it in the garbage closet which is just a very small closet that only fits the garbage can and a broom with 2 shelves above it for storage. Every time I opened the door there was a nice release of the clean linen scent. It covered the garbage smell nicely. I would purchase this again for the very small spaces but it really did no good to have it anywhere other than a small, closed in area. The clean linen scent is a very neutral smell.
