How Often Should I Replace My PUR Water Filter?

With the cost and waste associated with bottled water, home water filtration systems have grown increasingly popular in recent years. PUR water filters vary in design and type, depending on the filtration system. Knowing how and when to change your PUR filter will keep the system providing you with clean, healthy water.

Filters reduce contaminants from drinking water.

Purpose

Tap water contains potentially harmful contaminants, such as heavy metals, microbes, industrial pollutants and trace levels of pharmaceuticals. PUR filters contain an activated carbon microfilter to reduce these contaminants from your drinking water. The system also eliminates the odor and taste of chlorine while preserving valuable fluoride content.

Faucet Filters

Replace your PUR faucet filter every 100 gallons or approximately every two to three months. An indicator on the filter housing alerts you when the filter needs to be changed. To change the filter, remove the housing cap, pull out the old filter and install the new filter in the same direction. A damp rag makes a handy grip for loosening stubborn housing caps.

Pitchers and Dispensers

PUR pitcher and dispenser filters are effective for filtering up to 40 gallons of water. Replace these filters roughly every one to two months, depending on your household size and frequency of use. Some models feature an electronic light indicator on the lid. Replace a PUR pitcher or dispenser filter by removing the lid from the vessel, pulling out the old filter and installing a new one in its place.

Refrigerators

Depending on the refrigerator model, PUR refrigerator filters effectively filter between 100 to 200 gallons. These filters should be replaced every six months. The filter is located at the bottom of the refrigerator and may have a push-button for removal. Push this button to eject the old filter then remove the grille cap from the end of the filter. Twist the grille cap onto the new filter and insert the filter into the refrigerator. For models without a push-button, you must first turn off the ice maker. Twist the filter clockwise to remove it. After transferring the grille cap from the old to the new filter, insert the new filter into the refrigerator and twist it clockwise to install it. Don't forget to turn on the ice maker afterward.
