The convenience of having clean, safe drinking water at your fingertips is a lifesaver. The problem with tap water from your home is that you can never be too sure about it until you test it for quality.

When the water leaves a tap, it should be clean and available for drinking, but that is not always the case. The water you drink may be contaminated with lead. The pipes and service lines that carry water to your house are usually made of lead, which can get into our drinking supply and contaminate it. There are also places where it is advised not to drink the water for safety standards.

Luckily, there is an affordable and portable solution: a water purifying bottle.

You can fill them up from any source and let their purifying system do all the work to make it safe for you to drink while still being portable to carry.

Choosing your bottle is important otherwise, you may end up with one that leaks or have an unpleasant plastic aftertaste.

The environmental and economic benefits of reusable water bottles are undeniable. Also, you can find a good filtered water bottle for under $40, with some premium ones being much pricier. You may even find yourself drinking more clean water than usual.

The Difference Between Filtered and Purified Water

The difference between filtering and purifying water might be confusing for some, but it’s important to know the difference. Side-by-side filter and purifier bottles look and function the same. So what is the difference, and how to know which one to pick? 

Water bottles with filters are great for catching larger items, like silt and protozoan cysts, Salmonella, Escherichia coli, etc.

Water bottles with purifiers are a must-have for anyone who wants to stay healthy and safe from contamination. Using a UV-C light, they can catch or kill 99.99% of smaller contaminants like viruses, bacteria, fungi, microbes, etc. So, to summarize, a purifier is designed to catch or kill what your filter can’t.

Which Material To Choose For A Water Bottle?

Here is a list of the most common choices:


Almost all filtered drinking bottles will be made from BPA-free plastic. However, because plastic doesn’t have good insulation, the water won’t be refreshingly cool to drink. Also, these plastic bottles always have some kind of odor that is hard to get rid of, and companies also use the filter to solve this problem.

Stainless Steel

Stainless steel filtering water bottles are strong with a premium feeling and design, and not to mention they are good at keeping your water cold for up to 24h. Also, there is a less bad smell, and they are easy to clean and maintain.


Drinking water from glass is the best way to refresh yourself. But as you’ve probably realized, glass is easy to break, and with that, you lose portability.

1) UVBrite: Self-Cleaning Water Bottle


UVBrite is a self-cleaning “smart bottle” that uses UV-C light to kill up to 99% of bacteria, viruses, and fungi. Besides that, UVBrite is made from stainless steel, and it can keep hot and cold beverages at a temperature for upwards of 12 hours.

UV light emitted from UVBrite has a higher intensity than what’s naturally produced by sunlight, eliminating bacteria and viruses.

To use UVBrite, fill the bottle with water, put back the bottle lid on, and press the button to activate ultraviolet light. The purifier will make water safe in just 180 seconds. According to UVBrite, it can eliminate up to 99.99% of harmful germs in your water.

The self-cleaning capability ensures that your water bottle never gets nasty. For example, when you use UVBrite to purify water, it also purifies the bottle simultaneously.

The bottle uses a rechargeable battery. The system will last for several weeks and purify up to 60 full bottles with a single charge.

The UVBrite’s UV-C LED light is rated to last for 10,000 hours, translating into over 29 thousand gallons of purifying power, which is impressive for a water bottle.

2) LifeStraw Go

You probably know LifeStraw, which most people use for hiking and outdoor activities. LifeStraw is now even more convenient and easy to use than ever before with LifeStraw Go purifying water bottles.

LifeStraw Go is a great option for short hikes near water sources. You can easily fill up a bottle anywhere on the go and have instantly clean water.

LifeStraw Go is a protection system for your water that will keep you safe from lead, bacteria, and parasites. In addition, the manufacturer claims it reduces chlorine taste to make the drinking experience better.

The built-in filter reduces chlorine and bad taste, thanks to its hollow fiber membrane & integrated activated carbon capsule.

We only heard one complaint, and it is about how difficult it is to drink water through a straw because the filtering system is attached to the straw directly. This bottle has less water volume than other bottles because of the big straw and integrated filtration system.

3) Brita Stainless Steel Bottle

Brita stainless steel water bottles are perfect for staying hydrated, especially on the go. They’re made without BPA and can keep your drink cold for up to 24 hours.

It’s perfect for anyone who constantly finds themselves away from their home water source. This portable filtration system allows you to take clean drinking water anywhere with ease, whether from public restrooms or city fountains.

The Brita bottle has a built-in activated carbon filter designed to remove chlorine and other contaminants while preserving certain healthy minerals. In addition, the unique housing of this product is made without BPA so that you won’t have the bad taste of water from the bottle.

The filter can last for about two months before needing replacement. You will use six filters in one year and spend just under $20 on water bottle replacements.

The downside of Brita filtering bottles is cleaning. Mold can grow easily if not washed properly and can lead to a bad odor of straw, and cleaning the straw without a straw cleaner can be tricky.

4) Astrea One

Astrea One is also one of the premium water filtering bottles, and it is made of stainless steel to keep your water cold.

The Astrea One filtered water bottle is a great choice for avoiding lead, benzene, and other harmful chemicals in the water. Unfortunately, the website doesn’t say anything about using the filter with water filled with bacteria, so we don’t advise you to use it for this application.

It also filters out chlorine and zinc to make water taste great. Also, Astrea One is certified to reduce over 20 contaminants like pesticides, pharmaceuticals, and lead. This water bottle is designed to last for a long time because it’s made from a stainless steel body and a BPA-free plastic lid.

We learned that Astrea One is great for filtering heavy metals, but behind that filtration stands a huge filter that takes up most of the bottle space, and it can last up to 3 months.

Although the filter is large, you can completely remove it for thorough cleaning of the bottle. The bottle opening is wide enough to fit a standard dish scrubber inside the lid, and it doesn’t require additional cleaning tools.

Astrea also offers a subscription service, so you never have to worry about replacing your filter. The cost of the filter is $12 and should be replaced every two months if used regularly.

Astrea One water bottle is ideal for those at work and who have bad tap water at home. The downside of Astrea One filtering water bottles is that it can’t filter bacteria.
