1. LifeStraw Go Water Filter Bottle

The best filtered water bottle overall

LifeStraw Go Water Filter Bottle best filtered water bottles

Brand: LifeStraw | Material: BPA-Free Plastic | Capacity: 22 oz | Price: 💰💰💰💰

You’ve probably heard of the LifeStraw, but did you know they have a whole water bottle too? Well, they do! The LifeStraw water bottle is designed in various colors and comes in 22oz or 1L sizes. Lifestraw made the filtration using a hollow fiber membrane, as well as an activated carbon filter. They claim this design removes 99.9999% of waterborne bacteria and 99.9% of waterborne protozoan parasites. The activated carbon works to reduce odor and chlorine, so your water is even purer.

Reviewers were very pleased with the Lifestraw water bottle, on the whole. They thought it was perfect for traveling, loved that the filter lasted a long time, and some who had issues received excellent and efficient customer service. However, a few users mentioned that the bottle leaked and that the water was pretty hard to suck out of the straw. Some responded that the water is more difficult to suck out due to the amount of filtering, so this may not be an ideal option for those who don’t want to suck too hard.

  • Ideal for traveling
  • Filter lasts a long time
  • Great customer service
  • Bottle leaks
  • Water is hard to suck out of straw

2. GoPure Water Filter Pod

The best versatile filter for water bottles

GoPure Water Filter Pod

Brand: GoPure | Material: BPA-Free Plastic, Diatomaceous earth, Silver | Capacity: No Bottle, Filter Only | Price: 💰💰💰

GoPure has designed a fascinating new water bottle (or any water container) filter. It is a small pod made of BPA-free plastic (which is recyclable), with a filter inside. To use, you can just plop it into a pitcher of water, a water bottle, and it will filter the water. GoPure also has water filters for animal water dishes, so they can also have the cleanest water. Each pod purifies 264 gallons of water, so they should last around six months, depending on the frequency of use. This filter removes cysts, algae, and asbestos from water, so it is not something to use for anything other than tap water. The GoPure website only allows you to buy these in packs of 2 or more, so if you want to spend less money and just try one out, Package Free has that option!

This funny little filter received many positive reviews from buyers. It made tap water taste great, was easy to use (just drop it into any water container!), and buyers were happy that the filter could even be used in their pets’ water bowls. One buyer’s only complaint was that their water didn’t taste any different from before, which made them question if the filter pod worked. 

  • Can be used for animals as well
  • Makes tap water taste way better
  • Easy to use in every water container
  • Water doesn’t taste different
  • Made someone less hydrated, though they aren’t sure it’s the filters’ fault

3. Brita Stainless Steel Filtered Water Bottle

The best insulated filtered water bottle

Brita Stainless Steel Filtered Water Bottle

Brand: Brita | Material: Stainless Steel | Capacity: 32 oz | Price: 💰💰💰💰

This Brita water bottle comes in 20oz and 32oz sizes, is stainless steel, and comes in various colors. Brita made this bottle with double-wall insulated for keeping your water at the perfect temperature. The filter reduces chlorine odor and taste, and the manufacturer recommends replacing it every 40 gallons. Needless to say, this filtered water bottle is not designed for drinking potentially contaminated, bacteria-filled water but is ideal for refining tap water

Buyers liked this filtered water bottle, overall. They liked that it kept their water cold, made their tap water taste good, and is a good size as well as being sturdy. However, some struggled to use the bottle correctly. Many seemed to believe that to drink from the bottle, they had to tilt the bottle up, when in reality, you are supposed to keep it level and just suck through the straw. Unfortunately, drinking from the bottle wrong meant that they didn’t get to drink at all! The only legitimate issue that buyers mentioned is that mold grew on the mouthpiece after very little usage. 

  • Keeps water cold
  • Good size and sturdy
  • Good for filtering tap water
  • Some struggled to use it properly
  • Mold grows in the mouthpiece easily

4. Survimate Filtered Water Bottle

Brand: Survimate | Material: BPA-Free Tritan Copolyester | Capacity: Not Specified | Price: 💰💰💰

This sleek filtered water bottle from Survimate is an excellent addition to this list. It comes in various colors, and Survimate used BPA-free Tritan Copolyester to make it. The bottle comes with a straw-style lid, so you don’t have to take a lid off and on to gain access to your water. The filter is made from various materials such as medical-grade PP cotton, coconut shell activated carbon, and medical-grade hollow fiber membrane. The manufacturer designed the filters to last through 1500L of water, although this may vary depending on the water quality.

Overall, buyers loved these filtered water bottles. They appreciated that there was no weird aftertaste from the filter, though it was a perfectly sized bottle, and found both the filter and bottle to be good quality. Some, however, were not satisfied. A few mentioned that the water tasted bad or had a bad aftertaste. Others expressed frustration with needing to suck on the straw several times (5-7) before any water came through. 

  • Perfect size bottle

This purchase comes with a bottle that comes in a variety of colors and patterns and a cap that uses UV light to purify the water inside from bacteria and viruses. The bottle has double-wall vacuum insulation to keep your water at whatever temperature you want. CrazCap’s bottle and UV light are certainly not cheap, although, with the money you’ll save on bottled water, it could be a worthwhile investment!

The majority of buyers were extremely pleased with this unique water purifying bottle. They loved how infrequently they had to charge it, were impressed that it worked, and thought the bottle design was beautiful. However, there were some complaints. Some mentioned that the bottle didn’t last very long or that the cap didn’t function for more than a couple of months. There were also mentions of the package arriving already opened and/or damaged. It is worth noting that all the reviews we looked at were from Amazon since there were significantly more than on the product website.

The filter inside the bottle lasts 394 uses (with the Brita bottle) and is best at filtering out chlorine and other various particles that could be in your tap water. Brita did not design this bottle for drinking water straight from a creek, so keep that in mind.

The vast majority of buyers were happy with this Brita water bottle, and their kids loved it too! Most parents reported this bottle helped their kids want to drink more water because it is such a fun bottle and because it made their water taste great. One buyer commented that she didn’t like that you have to gulp some air before the water comes through the filter, and one other buyer mentioned that the lid was very hard to screw on and off.

What to Look for in the Best Filtered Water Bottle

When it comes to finding the best filtered water bottle for you, there are a couple of aspects to consider.

1

Lid Types

There are so many random types of lids these days! Some have straws, some are just a typical screw-on lid, and some are even a combination of both. Whatever type of lid you want, you can find it! 

Straw Lids

Straw lids are probably the easiest. You don’t have to unscrew anything or tilt your head back and risk splashing water on yourself. They are, however, capable of growing mold or mildew a lot more easily than most other lid types and, indeed, something to consider. If you aren’t willing to thoroughly clean your water bottle most days, this may not be the best choice for you.

Screw-on/off Lids

The most basic type of lid! There is always a chance of getting water all over yourself, but if you’re able to adjust to this type of lid quickly, then it just might be worth it! We love that this type doesn’t develop mold as straws do.

2

Type of Filter

Just because a water bottle claims to be filtered doesn’t mean that it has the type of filter you want. Some filters can only remove chlorine from tap water, while others are designed to eliminate all sorts of bacteria and microbes from water taken straight from a natural source like a creek. Especially if you want to go backpacking or traveling somewhere with low water quality, you need to be sure to find a water bottle that specifies having a filter that gets rid of all the nasty things that will be in your water. As long as you read descriptions and all of the best filtered water bottle reviews, you should be safe!

Drink Safely!
