As a longtime user of PUR water filters, I’ve learned the ins and outs of replacing them to keep my drinking water fresh, clean, and contaminant-free. Changing the filter regularly is crucial to get the most from your PUR system. In this comprehensive guide, I’ll walk through the entire process step-by-step.
Whether you have a PUR pitcher, faucet mount, dispenser, or another filter type, replacing the cartridge occasionally preserves optimal performance. I’ll cover the basics for all models, with tips specific to certain systems. With a new filter in place, you can keep enjoying PUR’s superb chlorine reduction and removal of potentially harmful contaminants.
Why PUR Water Filters?
I switched to PUR years ago after learning how effectively it reduces chlorine taste and odor compared to alternatives like Brita. Chlorine is added to public water supplies as a disinfectant but can react with organic compounds to form potentially toxic byproducts.
PUR’s two-stage filtration combines activated carbon with ion exchange resins. This targets chlorine and its compounds for reduction up to 96% according to PUR. Other filters like Brita use only activated carbon, which primarily removes chlorine byproducts rather than free chlorine.
Additionally, PUR filters are independently certified to reduce lead, pharmaceuticals, microbial cysts, pesticides, mercury, and other concerning contaminants. Having PUR gives me peace of mind that harmful pollutants are being removed from my family’s drinking water.
Now let’s get into the details of replacing PUR filters to maintain that high level of water purification.
Preparing for PUR Filter Replacement
Before swapping out the old filter, some preparatory steps help ensure a smooth change. This involves gathering needed materials, locating the existing filter, and turning off any water supply to the system.
You’ll need the following:
- A new PUR filter cartridge (check model number to match your system)
- The owner’s manual for your specific PUR filter
- A bowl or sink
First, locate the existing filter in your PUR system. For pitchers, it’s inside the lid. Faucet systems contain the filter in the main housing attached to the tap. Dispensers house the filter internally or behind a panel.
Once you’ve found the filter, turn off any water leading to the unit. For faucet systems, shut off the line valve supplying that tap. This prevents leaks or spurting during replacement.
Review the manual to find filter change instructions specific to your PUR model. Now we’re ready to remove the old cartridge.
Removing the Old PUR Filter
With the water supply off, carefully detach the existing filter. Most twist or turn to unlock from the housing before pulling out.
Pitchers: Lift the pitcher lid and turn the filter clockwise to unlock from the lid sockets. Pull up firmly to remove it.
Faucet Filters: Turn the housing base counterclockwise and detach it from the unit. A vertical pull removes the cylindrical filter.
Dispensers: Access varies by model. Some have front panels that snap off to access the filter. Others require tilting the dispenser to remove a hatch underneath. Consult the manual for your particular unit.
With the old filter removed, discard it responsibly. Do not reuse old cartridges. Some recyclers accept spent filters, or toss them in the garbage if no recycling exists in your area.
For faucet systems, inspect the housing bowl and clean any dirt or debris. Check the filter compartment in pitchers as well.
Now let’s get the new replacement filter prepared and installed.
Preparing and Installing the New PUR Filter
PUR filters require preparation before first use to flush out any loose carbon particles. The process differs slightly for the two main types.
PUR Plus Filters
PUR Plus filters feature enhanced contaminant reduction. To prepare a new Plus cartridge:
Step 1: Place the filter in a bowl and completely submerge in cold water for 15 minutes. This fully saturates the filter.
Step 2: Remove the filter and rinse under cold tap water for 10 seconds to flush out carbon dust.
Step 3: Allow excess water to drain out by holding the filter vertically for 15-30 seconds.
PUR Basic Filters
For standard Basic filters, simply rinse under cold tap water for 15 seconds.
Once prepped, we can install the new cartridge. Insert it into the system, aligning any tabs with the housing slots. Push firmly until it clicks fully into place at the bottom.
Pitchers: Drop the filter into the lid socket. Rotate counterclockwise to secure it.
Faucets: Seat the filter in the housing bowl. Reattach the base by rotating it clockwise until tight.
Dispensers: Replace any panels removed earlier to access the internal filter. Replace and latch any covers.
Double-check that the new filter is firmly snapped in and oriented properly. We’re now ready to reattach the faucet systems and run the initial water flow.
Reattaching Faucet Systems
With the prepared filter installed, faucet systems can be reconnected to the water supply.
Hold the unit upright against the faucet, aligning the threading horizontally. Rotate the locking collar nut clockwise until hand-tight and snug.
Before turning the water back on, inspect the connections for any gaps or misalignment that could cause leaks. Tighten further if needed to prevent dripping.
Flushing the New Filter
Once secured, slowly turn the faucet or system handle to divert water flow through the new filter. For faucets, switch the lever to the “filter” setting if applicable.
Let cold water run for 5 minutes. This flushes out any loose carbon particles and activates the filter. Cloudiness, discoloration, or bubbles escaping during initial flow are normal as the cartridge is conditioned with use.
For faucet systems, remember to run cold water through the unit for 5 seconds before each use to activate the filter’s chlorine and contaminant reduction. Otherwise, water bypasses the filter.
Resetting Indicators
Some PUR filters have built-in indicators that show when to replace the filter based on the time or volume used. If applicable, reset this gauge after changing cartridges.
Electronic countdown timers: Press and hold the reset button on the display until the timer resets to the cartridge lifespan (typically 6 months).
Water usage monitors: Similarly, holding the reset button resets the usage indicator to zero.
Sticker indicators: Peel off the old sticker and apply the new indicator included with replacement cartridges.
Refer to the owner’s manual for resetting details specific to your model. With the change complete, your PUR filter is once again ready for optimal performance.
Enjoy Crystal Clear Water
By methodically replacing your PUR filter, you can continue to enjoy contaminant-free water with reduced chlorine for better taste. Changing cartridges every 6 months or 300 gallons maintains PUR systems at peak purification levels.
For families like mine, having great-tasting, cleaner water from the tap provides peace of mind that we’re avoiding potentially harmful pollutants. While initial investment in a PUR purchase may seem high, the savings over buying bottled water quickly offset the cost.

Related FAQs
How often do PUR filters need replacement?
PUR filters are designed to be replaced every 6 months or 300 gallons used, whichever comes first. This maintains optimal contaminant removal. Write the installation date on the cartridge or enter it in your phone’s calendar for an easy reminder.
What happens if I don’t change my PUR filter regularly?
Over time, the carbon and ion exchange media inside the filter become saturated with contaminants. This reduces filtration performance, allowing more chlorine, chemicals, particulates, and bad tastes through over a neglected filter’s lifespan.
Can I wash and reuse PUR filters?
No, PUR filters are designed for single use and should never be cleaned and reused. The internal media wears out after months of accumulation and cannot be restored by washing. Always replace with a new PUR cartridge for best performance.
Why is my new PUR filter leaking?
Ensure the filter is firmly pressed into the housing and securely locked into place. Run only cold water through the system and avoid over-tightening connections. Warm water or over-tightened collars can warp the plastic, causing leaks. If leaks persist, contact PUR customer support.
How do I know my PUR filter is working?
PUR filters should make water taste fresher by significantly reducing chlorine. But you cannot confirm the removal of other contaminants visually. Check indicators to know when a cartridge needs replacing. If ever in doubt, contact PUR to test your water’s purity.
Can I recycle my old PUR filter?
Some recyclers accept used filters, however availability varies regionally. Otherwise, safely discard spent cartridges in your normal refuse. Never reuse an old filter. Always replace PUR filters with a new one.
What PUR filter do I need for my model?
Check your owner’s manual or the label/markings on your existing filter to determine the correct replacement cartridge for your PUR system. Using the wrong filter type risks leakage or poor performance.
Why choose PUR over Brita?
While Brita filters remove some chlorine, PUR is certified to reduce nearly 100% for the freshest taste. PUR also removes more contaminants and is independently tested to ensure filtration performance.
Can I use PUR filters with hot water?
No, PUR systems are designed for only cold water. Hot water can warp or damage plastic components. Always run cold water through the filter for at least 5 seconds before first use from the tap to activate chlorine reduction.
How do I clean my PUR system?
For pitchers or dispensers, wash removable components in soapy dishwater. Do not place the filter cartridge in water. Faucet systems can be wiped down with a damp cloth and mild detergent. Never use harsh chemicals or soaps.
