Last 45 days. At last - the pure clean essence of nature's best captured in a liquid home fragrance. Almost lighter than air. Ambi-Pur enhances your home with a subtle yet lasting fragrance. Fine fragrances contain a blend of many elements known as top, heart and base notes. Crystal Ocean Waters blends these notes for maximum harmony. Sparkling marine fresh air and green notes emerge first. Fruity notes add refreshing fullness and personality. Woodsy notes add depth.
