Filtrete(フィルトレッテ) ハウス全体の芳香剤 エアコン炉用エアフィルター、Linen Breeze

Nice smell without being too powerful. Lasts for a while

this was a waste of my money. i opened both outlets for maximum smell but there was no effect. my house smells the same. I ignored the negative reviews and regretted this purchase. Please, do not buy!

Nice smell for whole house

I open all of them and make sure the open part is getting the air flow directly. You should have the air flowing through the filter first, then directly into the open part of the bulb, then on thru the system. If you have it installed backwards, it won’t work well. I’m on day 7 and my house smell great despite occasionally smoking inside. I taped them to the filter to keep them from getting stuck when changing filters.

This whole house air freshener didn’t work for me at all. It barely had any smell, and I couldn’t notice any difference in my home. Unfortunately, it ended up being a waste of money.
