Whether you’re traveling or simply want to improve the taste of your tap water, the best filtered water bottles offer a convenient way to remove potentially harmful bacteria, chemicals, and other contaminants. But what kind of filtering you’re looking for will be a major determining factor on which reusable bottle is best for you. No matter what kind of filtering you need, though, the best options all have filters that are easy to replace as needed. Plus, they come in a variety of sizes, materials, and styles, so there’s sure to be one that suits your needs.
What to consider when choosing a filtered water bottle
First, you’ll want to consider where you’ll be using your water bottle and the kind of contaminants you’ll need to filter out. Some water bottles feature multi-stage filters that can remove bacteria, viruses, parasites, particulates (such as microplastics), chemicals, and heavy metals. These can be particularly useful when traveling to areas where you’re not sure how safe the drinking water is or when planning your next outdoor adventure. But if you’re looking for a filtered water bottle that’ll be used primarily for tap water, there are plenty of chlorine and chemical-reducing filters that can help improve the taste and smell of your water but won’t help against things like giardia.
Water bottle material
Next, you’ll want to consider the material of your water bottle. Plastic options provide lightweight durability and are often available at a lower price, but they may absorb odors from things like dish soap. Stainless steel water bottles provide extra durability for traveling or outdoor use, and some feature double-walled insulation to keep your water cool. However, you may find that stainless steel gives water a slightly metallic taste. Lastly, glass bottles are nonporous, so they won’t change the taste of water or absorb odors, and they often feature rubber or silicone sleeves for some added impact resistance — but glass might not sustain drops as well as plastic or stainless steel. Whichever material you prefer, each of these types of water bottles has dishwasher-friendly options if easy cleaning is a must-have.
Finally, think about the special features you’d like your bottle to have. Some filtering water bottles can increase the alkalinity of your water. Other water bottles have bonuses like convenient carrying straps and multiple lids.
With these considerations in mind, scroll on for the best filtered water bottles, according to Amazon reviewers.
The tried-and-true one
- The membrane microfilter can clean approximately 264 gallons of water before needing to be replaced
- Filters bacteria, parasites, microplastics, chlorine, and more
- Comes with a carabiner
- With each purchase, the brand helps children gain access to healthy drinking water

The membrane microfilter has an impressively long life that lasts approximately 264 gallons before needing to be replaced.

The bottle is made of BPA-free plastic, boasts a silicone comfort straw, and proceeds from purchases of this bottle help deliver clean drinking water to children in need.
One reviewer wrote: “I moved from the midwest to the South about a year ago, and almost right away I started getting bad stomach aches, pains, etc. […] At some point, I started to wonder if it could be an issue with the water, so I started looking into filters. I decided to give this bottle a try, since the price was good and so were the reviews, and I wanted something I could carry with me. I am SO glad that I did, because almost overnight I stopped having stomach issues altogether. It is a *little* hard to drink through the straw, but nothing too bad- with as much filtration as this uses, it’s a small price to pay. Highly recommend it!”

Used with lake/river water and tap water. The purified water tastes great and looks very clean. We will be purchasing a couple more. Kinda spendy, but very much worth the money invested in our health when you consider how many parasites, viruses, and bacteria these filters remove. We are very happy with our purchase. Highly recommend!”

The one that increases alkalinity
- The removable filters can be used in multiple containers
- Insulated, stainless steel construction with two lid options
- Only one that increases alkalinity
- Some reviewers said it took a while to get used to the taste
- Does not remove bacteria or parasites
For a filter bottle that’ll increase the pH of your water, this stainless steel option is a great pick.

The filter lasts approximately 26 gallons and can be stored in the included waterproof pouch when not in use, and a three-pack of replacements is available. You can also use the filter pouch in any bottle.
Additionally, the bottle comes with two lids: a bamboo stopper with a steel handle and a sports cap with a straw and handle. While the insulated stainless steel construction helps to keep drinks hot for up to 24 hours and cold for up to 48 hours, the brand does not recommend using the filter pouch in hot water.
One reviewer wrote: “Love it!! I bought this bottle because I hate the taste of tap water and prefer clean, filtered water – a Ph filter is a bonus! […] I take it everywhere: to work, on trips or running errands. It doesn’t sweat, has a good capacity, and it fits nicely in the cup holder in my car as well as my backpack. I can easily refill it from any water fountain and thanks to the little filter, the water always tastes great. Love the two different lid options, too. I use both, but the straw lid is my favorite – so convenient. I saw that you can order extra filters on Amazon too, so I stocked up. I highly recommend this.”
