Reviews

"I would not buy this again. I was excited about it because I thought it would be like my car air freshener and last longer however, I am disappointed that it only lasted. I would say one day. I would either work on trying to get them to last a full 30 days or charge less and have them switched out every seven days but really after seven days. There’s no sense left at all. Maybe it would be better to make it like the car air fresheners where it’s liquid, so it will last longer and always give a vibrant sent. The scent was very vibrant for the first hour, and after that, it went down."

Scentra is compatible with all Alen air purifiers!

How long does a scent last?

How do I control scent intensity?

Open the Scentra dispenser to increase intensity, and close for less intensity. Always adjust intensity with the dispenser; do not lower purifier fan speed to adjust intensity as that may compromise purification.
