Take it loose from the faucet and flip the lever down on the filter in the on position. Take the cap off and remove the filter. Blow hard through it. You should hear a whirling noise of a gear, like a windmill. If not, I use a water dental pic to pulsate into it and clean it out. This is what makes the light work and when flow goes down, the light changes color. It's all mechanical. No battery. Just free up the gear so it turns freely to work the light. If standing in front of a mirror, you can actually see the light come on. PUR doesn't tell you this because they want you to purchase another one.

    I tried placing a straw in the hole on the inside of my unit and blowing hard several times. Sure enough, the green light is now working.

    Great advice!! I tried this and now the light works again. I called Pur first and they said that the battery was dead and I needed to buy a new filter.

    I can hear the gismo whirring when I blow on it but the light is still red, with or without the cartridge. Now what? buy a new one?

    Thank you so much! I actually didn't even have to go through all of the steps. After just removing the cap and filter, I noticed that the filter was not installed properly (and it was when I first installed it a few weeks ago, so I'm not sure how it moved). I just pulled it out, flipped the switch down to let the remaining water out, reinstalled the filter and cap, and - VOILA! All fixed here. Great information for future reference though. Thank you, Kathy!

    Also, has anyone else has noticed the white crumb-like debris when opening a brand new filter? I called Pur and they told me this is normal, and that I should always run a new filter for 5 minutes before using it. I never did that before, but this time I tasted a sip of the water before I ran it through for 5 minutes and it had a funky taste (plastic?), and it was actually slimy, even on my hands. Now I always wash off the filter before installing, I wonder if that stuff is silica, eww ??

    I tried the blowing of the filter. I installed a new filter. I saw the green light flash as I closed the top proving the mechanism is working. I clip onto faucet. Run the filter for the recommended 5 minutes. Light does not work at all. Its less than a year old and it did used to work.

    Try using a little vinegar to clean. I believe hard water deposits clog the wheel. You should hear the wheel spinning/whirring when you blow.

    Thanks! That did the trick. I used a pointed skewer to move the wheel. It was stuck. Now it works fine..

    Even though I heard the whirring sound, still no light... Any other ideas?

  • Anonymous Jul 23, 2018

    I blew hard and heard the whirring sound. Did it twice but it worked for only the first time after I put it back. I then take my new filter out, press the black hole firmly (let as little water out as possible) inside the unit housing and turn on the water to create pressure as if the filter is in the unit. Turn on and off the water several time. Finally, the light on every time I turn on my Pur filter.

    Got a new PUR Faucet device. Light was not working. I did the way you described and it worked. Now everytime I start my tap water, Light blinks for initial few seconds and then goes off. Thanks a ton. :)

    Different water supplies have varying amounts of minerals and sediment. This can cause problems.
    I cleaned mine using sanitizer from a home-brew store. Works great!
    You could alternatively soak your empty faucet in a mixture of cold water and white vinegar. 50-50. This will pull out dirt and any micro mould spores that end up growing in the hidden places. This should be done at least once a year. Twice is better.
    Also, while empty, take out the little sieve plate, which is the last thing the water goes through and soak that in white vinegar. Then run water from the faucet through the hole, reverse flow if you will and this will also help to remove any trapped sediment and help it to work better.

    I've read all comments did a few. I've had my Pur for about 7 years an now the light is out. So I guess it's about time to upgrade. Don't want to be drinking bad water.

Light now works, but it’s green, despite the filter’s being close to needing replacement.

Only removes very little chlorine that's in our water. Better off throwing it away and replace it with a reverse osmosis. if you're looking for clean water

SOURCE: Unable to loosen and unscrew kitchen faucet screen...

If you have a lime problem, try soaking the tip in boiling water with vineger added to it. The acetic acid in the vineger disolves the lime. I did it just last week when I serviced my kitchen faucet. It may take quite a while for the lime to disolve, but in the end you will achieve your goal.

Trying to put a pur water filter on a tuscany kitchen faucet threads do not match


Please check with a store like lowes to find out how you can update the faucet head in order to fit the pur water filter. You can reach lowes at 1 (800) 445-6937. They offer different fossette parts/designs.

Thank you.

How do you fix the light in a Pur faucet filter

It could be mineralized, try soaking it in vinegar or scale remover.

Low Water pressure from the unfiltered spout on the Pur wat?r filter rf-9999. Plenty of pressure in the line.

Check out the nozzle screen for clogging. And if that does not do it then the cartridge inside your faucet is not operating properly. And those cartridges can usually be replaced. If faucet is a Moen it has a lifetime warranty and all you do is call them and they send to your home a brand new replacement cartridge. Do U have a Moen?

Why is my Pur faucet filter so slow? It was not before

You either need to clean the the screen filters prior to as they may be blocked. The filter cartridge itself my need to be changed as you don't say how old it is.

Which glue to reattach chromed plastic to plastic?

Use old fashioned model cement. Not the child safe type. The old type will melt the styrene to the styrene. The new stuff only fills the gap but never really makes a good bond.

Can't remove the filter from my Pur Flavor Options faucet mount water filter

When mine gets stuck I stick the handle of a fork or spoon into the hole where the water comes out and use that to unscrew it. Works like a charm every time.

Water Filter Leaks

Since you weren't very specific where it leaks or when it started (like after a filter change) it could be tough to troubleshoot this leak.

If it is leaking at the faucet connection try tightening up where it screws onto the faucet. Depending on your strength (or lack of) you may need to use pliers to get a tight connection. Don't go crazy tight or it will crack the plastic fitting. If it still leaks remove the unit from the faucet and check the rubber washer inside where it screws onto the faucet. Make sure it's still there and is centered inside the cup and seated properly. Then reattach the unit to the faucet and tighten it well.

If it's leaking from the main body try removing the filter and reinstalling it making sure you have seated the filter properly and screwed on the cover correctly, and all the way. When it is tight the water outlet will be exactly at the bottom of the unit. Sometimes it's tricky getting it tight enough especially with wet hands.

Finally, if the leak is coming from the filter on/off selector this could be tough to fix. I would try firmly pushing and pulling the selector knob in and out several times while in both the on and off positions. This may re-seat the leaking seal. I wouldn't be too hopeful about this fix though. You may need to replace the unit if this part is leaking.
