Can you add a filter easily? do you need to change the straw for this? Any idea if it's NSF certified? Maybe it's on the label if it is. Thanks!

Sorry I cannot help you since this water bottle sweats I just used it one time.

I'm not sure if you can add a fliter but I stop using it being the fact that dirt was getting in the straw and there was no way of cleaning it. I also didn't see on the label that it was NSF certified

The straw is made out of BPA free plastic, you simply take the top and straw apart, and rinse it out, or you can soak it in soapy water to make sure it's clean. I just use some hot water quickly to rinse the flip top and the straw. No, you do not have to keep replacing it.

It's been 4 months and my water filter still seems to be working great (2 person household.) Would be great if someone could post a link to a consumer reports type article about this subject. Of course the mnfctr is going to recommend faster changes than are necessary to get you to buy more. I just set up 3 month regular shipment from Amazon, to be safe.

You may want to contact the manufacturer to get a better explanation. What I can tell you is that you do want to soak and shake the filter in water for a few minutes. And then you will filter about 1 gallon through your pitcher and dump that before use. You will see that the water is kind of gray from this gray dust like stuff that comes from the filter. Not sure what it is, but I figure you don't really want to consume it! Definitely pre-soaking IS required.

You can remove the bite valve, and its tough to get inside of it to clean. I use a q-tip. You cannot just use the straw.

I just purchased this based on the answers to this question saying that the filter was removable. I previously had the Teavana option and that was my problem with it in that the filter got all clogged and it was not removable so I had to throw it out and look for a replacement. I can tell you after an insane amount of pulling, wiggling, teasing.. this filter DOES NOT come out.

You can buy replacement filters on amazon, I don't know if the straw is replaceable.

i dont you use filters, infact i bought the permanent lid cover cause the provided lid cover kept falling off the lid blocking the container ,leaving me with a mess

No, there isnt a modification that I know of unless you design your own, but I havent seen any fine debris escaping. Sometimes the water seems to get cloudy while using, but honestly I think its tiny air bubbles as they disappear within seconds of turning the unit off. The filter chamber has very fine mesh fabric covering it. Very fine.

You should add some ceramic rings in a tray and add some carbon in another tray. This should really help. There is a fiber sheet provided for each tray that works well, but I like rings and carbon to better clarify the water. You have the ability to set this filter up the way you prefer.

The newer models dont require filter replacement. Some of the older ones we sold do have optional ones. Historically they did not use filters on these, but modern drinkers don't want grounds in the bottom of the cup.The easiest way though is to just use some fine cheesecloth which you can put around the siphoning piece if you like

Amber, yes, Theresa answered correctly but here is some additional information. The filter straw is rated for 25 gallons in Turbid or Stagnant water. If the water is very dirty it will clog from the porosity of the filter being clogged up. But as Theresa noted, the Back-Flush kit is designed to help restore flow and extend the life of the straw. In clear water, the filter straw is rated to remove bacteriological contaminants including Chlorine, Heavy Metals (Lead) and VOC (Volatile Organic Compounds) for 200+ gallons. But when the water is not clear (dirty water) the useful life of the straw will be reduced. So the goal is to always drink from the clearest water available to you to give it the longest life possible. But the straws useable life is done when, even after back-flushing, you can no longer draw water through the straw. As long as you can draw water through the straw it is still working.

Fine... I always squeezed/filtered the best water I could find. I thought the lake water might have a bad taste, but even that was palatable right out of the filter. That said, I typically keep a little lemon juice for my pack-bladder. After my trip, I back-flushed the filter and didn't see any particulates, so again, all the water I filtered was pretty clear. My $.02

There is not a filter required on this particular model. It works fine, I've had for several months at work but it's a half gallon so it's goes through the water a bit faster than the ones I have at home but I've been quite happy with this one. Good luck!

I think the directions said you had to run quite a bit of water when you first replace the filter. We did that and had no problems with the taste. Hope it gets better.

I never noticed that. I just put it in the filter holder. Make sure you rinse it well first. It works just fine.

It's my understanding that with proper back flushing and drying the filter will be good for unlimited storage... but hey, for the price, how cheap do we need to be. I have a few that I use on a regular basis and several in "permanent" storage (i.e. go bags). I have reused two of these on a regular basis for well over three months and still feel comfortable with their effectivity. However, I do not filter extremely turbid or dirty water. Such source water I prefilter and let settle before using the straw on them.
