Your body is important so treat it right. Whether you suffer from sensitive skin, dry hair, or brittle nails or you simply want to improve your overall health making the switch to a Life Ionizer shower filter is a change you can make today that will have immediate and long-lasting results. According to the Water Quality Association (WQA), 10 minutes of showering is the equivalent of drinking an entire gallon of contaminated water. You wouldn’t drink water you know is contaminated so why shower in it? Our highly advanced double filtration system is quick and easy to install, removes 99% of chlorine and other contaminates, and works immediately making this the easiest change you can make to improve your health right now. The "Lifetime warranty on the shower filter" warranty covers any manufacturing defect. This applies to the shower filter itself and the composite filter should be replaced every 6 months and the Polymer Cotton Filters every one to two months. The Polymer Cotton Filters are inexpensive and make the Composite Filter last longer. Lifetime Warranty - Your Life Shower Filter has a lifetime warranty on the System (filters are replaced as noted).
