I was at the Ottawa Home and Garden show when I saw a booth advertising certified air cleaners. I have been in the market for an air purifier so I went over to see their product, "the Rainbow". They were giving away a free gift if I booked an in-home demonstration of the Rainbow so I booked one, and wow. I instantly fell in love. Not only is the Rainbow a certified air cleaner, but its also a vacuum cleaner, swiffer, mop, window cleaner, decontaminator, air freshner, inflator, deflator, you name it! It has everything you could ever want/need in a home cleaning system. You definitely need to see this product and EVERYONE deserves to have a Rainbow in their home!
