Thanks to Conair for sending me a free Portable Air Purifier. ConairPure™ Portable Air Purifier is ideal for small spaces and has a sleek design that fits any decor. It has a HEPA filter that removes dust, pollen, and other harmful particles. It is quiet, and I like that it can be used cordless for up to 22 hours on a single charge. The air purifier is lightweight, portable, and convenient to use in any location to enjoy clean air. Its compact size makes it an ideal addition to a desk or nightstand.
