The Best Water Purifier Bottles

Tired of lugging plastic bottles during your travels and adventures? Then you’re probably looking for a better alternative such as a water filtration bottle, which can give you fresh, drinkable water on the go. If you don’t want to get sick from polluted sources of water and are also thinking about the impact that plastics have on the environment, then you might want to look for the best filter water bottle. Here, we share the ultimate guide to the best water purifier bottles currently available in the market. 

Why You Need the Best Filtered Water Bottles

Most of the time, we get sick from drinking untreated water, especially because waterborne microorganisms are a huge issue in developing countries. Poor sanitation and the lack of water purification methods can lead to unsafe water entering drinking water supplies. Diseases like cholera, diarrhea, typhoid, and dysentery can be transmitted through water and can result in sickness. 

Luckily, there’s a solution for these problems, which is to bring a water purifier with you during your travels; these tools can easily and quickly filter dirty water and make your water safe to drink. If you have plans to travel internationally, make sure to have a water filter or a travel purifier bottle to help you manage your hydration needs. Doing this won’t just prevent illness from polluted water, but you’ll also save the environment from tons of plastics.  

What’s the Difference Between Water Purifiers and Filters? 

Unlike water filters, water purifiers use a water-cleansing method that can remove harmful chemicals, contaminants, and waterborne pathogens that create unsafe water sources such as salmonella, campylobacter, and E. coli. Viruses such as norovirus, rotavirus, and hepatitis A can also exist in bad water sources, along with parasites, protozoa, and heavy metals. On the other hand, a water filter uses a different way of cleansing, which forces water through a filtration system that separates solids larger compared to the pores of the filtration medium. 

While this can potentially allow contaminants smaller than the filtration system’s pore size, it can produce filtered water. Filtered water can be safe enough to drink, but some water filters might come with larger pores which may be too big to filter heavy metals, viruses, and chemicals.     

Types of Water Purifiers and Water Filters 

There are different kinds of portable water filters and purifier bottles currently available in the market that you can choose from.  

• UV Purifier and UV Light Options: This can be used to effectively disinfect water through ultraviolet light that works against parasites and bacteria but may not work as well in cloudy water.
• Activated Carbon Filter: This option can absorb organic and inorganic compounds by chemically attaching to them and then removing them from the water. It also removes chemicals such as iodine and chlorine, which improves the flavor and odor of the water. The only downside to a carbon filter is that it won’t remove microbes or kill microorganisms, so it’s best to pair them with another filtration method. 
• Chemical Purifiers: Iodine and chlorine compounds are common examples of chemicals that can be effective against viruses and bacteria. 
• Pump or Gravity Filter: Here, you can use porous materials to push water through while removing microbes of a specific size. While these won’t normally remove viruses, there is an electrochemical filter that can be added to help improve the filtration process. 

But no matter which filter you choose, it’s important to avoid heavily contaminated water that may come with metals and chemicals at all costs. Unfortunately, many purifiers aren’t able to remove these elements well enough to be safe to drink. Moreover, never drink from water sources that could potentially have viral contamination if you’re using water filters that aren’t rated to filter viruses.  

Why You Should Consider Viruses When Choosing Water Purifiers 

A virus is a microscopic organism and is much smaller compared to bacteria and parasites; when ingested, it can cause disease and can be transferred through contact with human or animal waste. Throughout Europe and North America, the risk of viruses inside rural water sources and tap water is low. Unfortunately, the same can’t be said of urban and rural centers in developing countries which will often lead to contamination in water supplies. 

In some areas, bathing and waste disposal in streams and rural lakes will often contaminate water sources with viruses from people. Moreover, leaks in underground pipes can combine freshwater with wastewater, leaving viruses in tap water without any warning. It’s because of these reasons that it’s essential to have a portable water purifier that can remove viruses as well as parasites and protozoa when traveling abroad.

The manufacturer recommends replacing the bottle every 3 months since it can get more difficult to suck the water through the straw; this can be costly since you’ll need to buy a brand-new product each time.

Features to Consider in Water Purifier Bottles

When choosing the right water purifier bottle, it’s important to remember to look for certain features that can help you decide based on your needs and preferences. These include filter and filtering capacity, taste, ease of use, cleanup, and construction materials. All of these are factors that should be considered when looking for the right water purifier bottle. 

Filtering

When looking for a reusable water bottle, you must ensure that the filtering mechanism can filter out harmful contaminants such as viruses, bacteria, and other impure compounds from the water source. It’s also important to consider if the filter leaves any particles in the water after it’s filtered. Moreover, you may want to think about how easy it is to replace the filters and whether replacements are included.  

Materials

Many filtered water bottles are often made from stainless steel or plastic but if you’re looking for an affordable option, be sure that it’s BPA-free. Make sure that it’s durable as well, and ask yourself if it could get a dent after dropping it once or twice. If you’re a hiker, it’s also a good idea to check whether the material is too heavy or not. 

Taste

This is an obvious consideration to make, especially if you want to get a filtered water bottle that will provide you with fresh-tasting water. Moreover, if you don’t want to get remnants of chemical tastes or mineral odors such as chlorine, then make sure to choose one that can rid water of these. 

Ease of Use

Putting your bottle together needs to be quick and easy, which includes the insertion and replacement of the filter. You should also think about how much water flows from the mouthpiece or straw to your mouth. Think about whether or not you need to tilt your water purifier bottle before you get anything out of it. 

Cleanup

Look for a filtered water bottle that’s also easy to clean and check if your bottle is safe to clean inside a dishwasher or if you need to hand wash it. You should also consider whether it can be easily stored, and find out what you’re supposed to do with it after it’s been washed. 

Conclusion 

Now that you know where to get the best water purifier bottles and what to look for in one, you should be able to identify which will work well for you and your needs. Whether you’re going to another part of the world or simply going out camping, these water bottle filters will provide safe water for your peace of mind while saving you from spending hundreds on bottled water. Just keep in mind that you should purchase the option that suits the kind of activity that you need it for. 

If you’re going backpacking, then you may want to invest in something that kills all kinds of pathogens, but if you only need filtration for tap water, then the Grayl Geopress would be too much.
