Hi Linnao! The scent typically lasts 2-3 days and is perfect for a special event. ~ Meghan, Filter Fresh
Hi Darpan. These are not foam. Although the idea is intriguing, I'm having a hard time imagining how you might be able to make that work. It's a cardboard cutout with gel applied. ~ Meghan, Filter Fresh
Hi EEEE! We see a few days to a week in testing! ~ Meghan, Filter Fresh

I've only seen them sold individually in the st ore. I ordered te 6 pack online & picked up in the store.
Hi maryanne, unfortunately for this home air freshener, if ordered on Homedepot.com, will be purchased and shipped as it appears on Homedepot.com. We are not able to make changes to the product and do not offer the Balsam scent. We appreciate your business and look forward to serving you in the future. Thank you for shopping Home Depot!
