Unbelievable, THEY DO WORK!!
I put these around right out of the packing.  After one day, I have noticed the lack of familiar smells that were just in the background and annoying.  I opted to buy the largest, 500g, available, thinking other people’s reason for not working maybe too small for a large room.  I placed one in a cats litter box area. That lingering, not dirty cat litter smell but just cat litter smell is gone. The cooking smells in the kitchen dissipated quickly and I can’t wait to see if they cut down on dust. I am so pleased after one day, that I’ve already ordered 5 more.  These are going to be definite gifts for Christmas!!<br /><br />I am going to make sure to recharge them monthly in the sun. For me, these things work perfectly!!
