Made with pleated filter technology for 3X longer life compared to our standard Brita filters, lasting up to 6 months*. Longlast replacement filters reduce lead, mercury, asbestos, cadmium and additional contaminants (substances reduced may not be in all users' water). The pull top cap on these filters makes insertion and removal easy. Keeps a healthy level of fluoride, a water additive that promotes strong teeth (applied to fluoridated municipal tap water). *Approximation based on 454L filter life and average family usage of 11 glasses per day.
