I have Elixir and plug & play air purifier by O2 cure and they not only take care of the indoor air but they have also helped me with my pollen and dust allergies as well as controlled cross-contamination of cold/cough. I don't fall sick anymore in the pollen season and the air purifierS also works well with odour. Within few minutes it treats any odour. It's been a great investment for me. A big Thankyou to team O2 cure for consulting me on the most suitable air purification solution for my health
