But some filtration systems, like PUR, go a step further to include filters made from activated carbon for even smaller pores for the water to pass through. PUR filters also include ion exchange materials for trapping unwanted metals.

The standard pitcher replacement filter is made of ion exchange resin and granular activated carbon. The PUR Plus Pitcher replacement filter contains ion exchange resin and granular activated carbon enclosed within a pleated microfilter.

Do PUR Filters Work? It depends on what's in your water. With proper upkeep, PUR pitchers are a great solution for some water quality concerns, but it is important to understand what they can and cannot do.

While not all generic filters reduce chlorine, PUR water filters all reduce chlorine and improve taste and odor. In fact, our PUR PLUS Mineral Core™ Faucet Filters filter water over minerals in the filter itself, specifically to ensure the water tastes great.

Polyurethane rigid foam (or PUR for short) has been used in construction since the 1960s as a high-performance insulation material. Continued technical developments in Europe and the US have led to the next product generation which is often called polyisocyanurate or rigid polyiso foam (or PIR for short).

As water flows through the filter, physical and chemical contaminants are adsorbed by the carbon while heavy metals like lead and mercury are adsorbed by the ion exchange materials.

These filters work to absorb and/or dissolve unwanted particles along with neutralizing bad odors. But some filtration systems, like PUR, go a step further to include filters made from activated carbon for even smaller pores for the water to pass through.

PUR pitcher filters have been rigorously tested and certified by NSF to reduce microplastics, chlorine, mercury, copper, zinc and other chemical & physical substances* that can cause bad taste and odor in your drinking water.

Polyurethane (PUR) is a resilient, flexible and durable manufactured material. There are various types of polyurethanes, which look and feel very different from each other. They are used in a very broad range of products.
