Frequently Asked Questions - PFM420W PUR
How often should I replace the PUR PFM420W filter?
You should replace the filter every 2 months or after filtering 40 gallons (151 liters) of water, whichever comes first.
How do I know when to change the filter?
Most PUR pitchers include a filter indicator. If your model doesn't have one, monitor the water flow and taste – when flow slows noticeably or water has an odd taste, it's time to replace the filter.
Can I use hot water in the PFM420W pitcher?
No, you should only use cold tap water. Hot water can damage the filter media and the pitcher, and may cause bacterial growth inside the filter.
How do I install a new filter in the pitcher?
To install, remove the old filter, soak the new PFM420W filter in a bowl of cold water for 5 minutes, rinse it, then press it firmly into the reservoir until it clicks into place. Run two pitchers of water through before you start drinking.
How do I clean the pitcher?
Disassemble the pitcher, wash the lid, reservoir, and spout with mild dish soap and warm water. Rinse thoroughly. Do not put the pitcher in the dishwasher, as heat can warp the plastic and damage the filter seat.
Is the PFM420W filter certified to reduce lead?
Yes, this filter is certified to NSF/ANSI 53 for lead reduction, along with other contaminants. It also meets NSF/ANSI 42 for chlorine taste and odor reduction.
Why does my filtered water taste different after replacing the filter?
A new filter may initially release tiny carbon particles. This is normal. Run two full pitchers of water through and discard that water. Also, the activated carbon can neutralize any residual chlorine, so the taste may be cleaner and fresher.
Can I put the PUR PFM420W pitcher in the refrigerator?
Yes, the pitcher is designed to fit in a standard refrigerator door shelf. Keep it refrigerated for the most refreshing cold water. The filter works better when the water is cool.
How long does it take to filter a full pitcher?
It typically takes about 5–10 minutes to filter a full pitcher. The rate can vary depending on water pressure and filter life. A clogged filter will slow down the process.
What is the capacity of the PFM420W pitcher?
The pitcher has a total capacity of 7 cups (1.6 liters), with a filtered water reservoir of about 5 cups (1.2 liters). The remaining space holds the unfiltered water.
