Buying water cartridges in multi packs is often the cheapest option so, for example, if you were looking for the #OB03 you could choose from different packs of 6, 5, 4 or 3 Brita filters. These cartridges fit a number of different Brita water dispensers, coolers and pitchers and need to be replaced when 40 gallons of water has been filtered or every two months. In the case of water coolers two filters will be required and will need changing every 80 gallons or four months.
Like every Brita filter these cartridges are tested and certified by the NSF and reduce mercury, lead, benzene, chlorine and zinc amongst other harmful things. Their use will improve the taste and odor of your water. Other products made by Brita include professional water filter systems and cartridges for vending machines, coffee machines, dishwashers and combination ovens.
Using these products you know you are in safe hands as the company has been among the leading experts in the field of water optimisation for almost 40 years. Quality by their continuing focus on research and development of products.
