this is good, odourless. really has no scent. best part i love is their product is safe for babies. so even if you accidentally spray into their eyes its okay cos its water based. i bought last yr and still using the pocket spray but the machine is quite high maintainable so i used till my baby was few months old. solution on can last ard 5 to 6 days depending on how much u used.
Best to go to those selling the scents shop to purchase the purifier (:
