PHILIPS BPA-Free Tritan Filtered Water Bottle - 22 oz Reusable Travel Water Bottle with GoZero Everyday Filter, Replaces 450 Plastic Bottles - Perfect for Hiking, Camping, Gym & Outdoor Activities (Pink)

Great item! Really filters tap water, you can taste the difference. Super convenient for drinking water anywhere and not needing to cause more environmental harm with disposable bottled water, not to mention it saves you money in the long run. I own both the Brita and Philips brand of these filter style bottles, both work well, but I prefer the design of the Philips. The inside of the Brita spout has a ridge in the silicone that keeps trapping bacteria no matter how much I clean it.The bottles are a bit brighter in person than the colors shown in the photos, just something to note. I have used it every day for two months now and there is no mold issue in the cap. Just wash the cap and attached straw tip frequently. I do every time I refill.You need to hold this upright and suck through the straw like you are a kid using a sippy cup, lol. If you try to tilt and pour, nothing will come out! Also I can never seem to drink the last bit of water in the bottle, I always have to unscrew the top and pour. Minor issue, but wanted to mention in case someone finds that annoying. It's a well-designed product, does not leak. Oh and last thing to mention - the plastic can get fingerprints on it very easily and does not keep cool, so if those things are important to you, get the stainless steel version. I am one of those odd people that likes their water room temperature so I don't mind, and I like seeing how much water I have left, so that's why I got the plastic one.EDIT: Been using this bottle for close to a year now. I am seeing all these reviews talk about mold. Well, you really have to ***WASH FREQUENTLY EVERY DAY*** to keep the mold away. Do not let it sit overnight with your saliva all over the spout. I have uploaded a new photo and you can see the only speck of mold I have is oddly on the plastic portion and not the silicone parts. I am not even sure if it's mold tbh, could just be a gray dot of discolored plastic? The color is also way off, because it was taken in the kitchen under fluorescent lighting.Every single night I wash the entire bottle and cap, including sticking a straw cleaner in the spout opening, then let it completely air dry, LID OPEN, before using again the next day and this habit has kept the mold away! If you don't mind all the washing effort, then you probably won't have a mold issue, but if you are a low maintenance person, this is not a bottle for you.
