Best decision we ever made was to purchase our Rainbow Air Purifier! And then to learn we could actually get it for free was AMAZING. I’ll be honest I was a little nervous about selling 2 units in 12 shows but In the first 3 shows my 2 units were sold. I went on to sell several more because once you see how amazing they really are they sell themselves. Our Rainbow has decreased our dust by at least 80% .Our return air filters are only being changed every 3-4 months and still aren’t covered in dust rather than every month. My husband has been able to stop his allergy meds completely. THE AIR QUALITY IS SO CLEAN ITS AMAZING! I could go on and on but to sum it up I LOVE MY RAINBOW!
