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

Yes, it is. Also, FYI, I am unhappy with the small hole on top, plus space around the straw that allow leaking if it tips or falls over. I read others note this & thought it would not be a problem for me, but it has been. Currently looking for one like this (I like all the other features.) w/o holes on top.

I did sometimes, but I realized it was user error. If the mouthpiece is not fully opened and the straw isn't all the way on, you can't get anything out of it. Hope it helps!!! That seemed to help for me :)

There are many ways to modify the filter compartments on this unit. I do not know if there is a filter on the market that will replace this one but google some of the biocube DIY filter ideas. The floss filter is really not necessary in a healthy reef system anyway. When I have time the filter and bio balls will be pulled out and replaced with an algae turf scrubber setup and when necessary a small bit of filter floss to help clear cloudy water. Good luck!

1. There is a little see-through sticker that comes with the pitcher, and a smaller marking sticker that you use to show when you put the new filter in, and the month that is two months later. For instance, I put the little marker over August - October. That will remind me that the two months is up. However, I live alone, so I figure my filter will last at least twice as long, so in October, I'll move the marker to October - December. I would use the 40 gallons, but that's just my opinion. 2. I'd have to think the shelf life of the unused filters is extremely long. I believe it's just charcoal inside a plastic casing, and I don't know why that would go bad. I ordered a pack of three spares, and I'm not worried about them going bad. I will probably take me at least a year to use them up. This water, cold, tastes delicious - the first water I've enjoyed drinking. (I'm not much of a water drinker, so having this pitcher has helped me drink more and keep hydrated much better than before I got it.)

Yes, there is another filter you can purchase for it. I did, and have not had to use it yet.

Yes. You may have to remove the filter floss or just use less floss. I can stick this in a nano filter even.

It requires one filter. Availability and duration of use may be as stated by the others, but I had a huge problem changing the filters - since one has to unscrew the outer cover & mine stuck tight. Since it is all plastic, there is no place to grip it. Maybe this was a problem only I had, but it was a killer.

It makes a great gravity filter--I purchased some surgical tubing (no memory coils) that attach to each end of the filter. The "uphill" tube inserts into the water source (bucket or bear canister), when with some sucking, the water will siphon up and over the side, and down through the filter, into the downhill tube and your water bottle. I do not use the sawyer bottle, except for storage. Once the first container is filled, others are quickly put in it's place until the source is out of water, and the cycle repeates. I love the backflow syringe for instant cleaning--BEST feature of the whole device!

The filter is replaceable. Therefore, it can be taken out, and the bottle still be used and drink from the straw. Hope this helps you out.

I'v had mine for a couple months now and have no need to change the filter, It's a metal type filter and completely washable, just rinse and re-use I use mine for loose leaf tea and works wonderful. Hope this helps

Two thoughts... First, try sucking more. Each time you fill the bottle, especially the very first time on each filter, it takes me 4-6 sucks to get the water up through the filter. Another possibility is that the straw part is not open the whole way. For some reason, it has a point the it stops that looks open but is not all the way, then you pull further to open completely. It is like the way some cars have two levels to push down to open a car window a little or the whole way down.

Samantha I not found any verification ..but I have used the filter in some nasty water to test it myself ..so far no side effects but I also have a back up .it is called the life straw

I don't know about that. Mine didn't work well and we eventually tossed it. (Darn! Wish I'd kept the straw for you!)

I have not changed the filter yet. I am not happy with the bottle. It leaks and siphons for no apparent reason. I have air coming out of the cap when there shouldn't be any coming out. There are other issues others have had and you can see them at Amazon. The seller has ignored my letter that I sent.

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.

Never had the problem with algae. I buy usually every 4-6 month a new filter, can tell on the taste when I need a new one. If it's a replacement filter maybe you bought an off brand which I did one time too, but the quality of the filter is not the same. Maybe it could also be the disc with mineral stone. You have to boil the stone before you use them. It also needs to be reboiled every 6 month. Personally do not use the mineral stone disk, don't like the taste of the water with it. Hope could give you an insight with it.
