Filter water bottles offer a convenient and safe way to drink clean water no matter where you are. They are lightweight and portable, so you can take them with you when hiking, camping, working, exercising, or traveling.

Just like water filter pitchers, filter water bottles remove harmful chemicals and contaminants from water using a built-in filtration system. They can be used for regular tap water, but they are especially useful when you are unsure of the water quality or when there is limited access to clean water. Also, a reusable filter water bottle is a handy eco-friendly alternative to single-use plastic water bottles.

What to Consider When Choosing the Best Filter Water Bottle

Whether you need a new water bottle for camping, hiking, or just hanging out, there are many different filter water bottles to choose from. Features like material, filtration type, and lid design can play a factor in figuring out which is best for you. Here are some important things to look for when choosing the best filter water bottle.

Material

Filter water bottles are available in different materials including stainless steel, plastic, and glass. The material impacts the water bottle’s durability and weight as well as the quality of the water.

  • If choosing a stainless steel option, look for 18/8 food-grade stainless steel, which means the bottle consists of 18 percent chromium and 8 percent nickel. Double-walled vacuum insulated water bottles are a common type of stainless steel water bottle. They contain multiple layers separated by a vacuum, which helps keep beverages at their optimal temperature. Stainless steel water bottles are durable, making them a good option for outdoor adventures like hiking.
  • Plastic water bottles weigh less than other types of water bottles, which makes them a good choice for those looking for a lightweight water bottle. If opting for a plastic water bottle, make certain it is BPA-free, meaning it is free of the chemical bisphenol A.
  • Glass water bottles also keep water fresh while preventing chemicals from getting into the water. Filter water bottles are easy to clean and some are even dishwasher safe, but it’s best to wash the filter by hand.

Size and Weight 

Size and weight are two important factors to consider when shopping for a filter water bottle. They come in a range of sizes with different water capacities. The average water capacity for filter water bottles is 17 to 24 ounces. The weight varies depending on the material and filtration system, but most are relatively lightweight. Plastic water bottles weigh less than stainless steel water bottles, and glass tends to be the heaviest.

Since they are typically used on the go, filter water bottles are designed to be portable. They can easily be thrown into a bag or brought on a hiking trip, and many have spill-proof caps, making them easier to transport. Some filter water bottles also come with carabiner clips for additional portability.

Filtration Mechanism

There are a few different filtration mechanisms for filter water bottles, including straw, gravity, squeeze, and pump filters. Each filtration system is designed to filter out harmful bacteria and contaminants from water.

  • Straw filters are contained within a straw and covered by a protective layer. The water is filtered while the user drinks through the straw.
  • Gravity filters use gravity to filter water. Dirty water sits above the clean water reservoir and flows through a filter with the help of gravity.
  • Squeeze filters function similarly to gravity filters but require the user to squeeze the water reservoir to get the water through the filter.
  • Pump filters have a small hand pump that is used to filter the water.

Filtration Systems

The filtration system determines what is filtered out of the water. Carbon and UV are two popular types of filters, and some water bottles use both types of filtration systems.

  • Carbon filters can effectively remove chemicals like chlorine from water, along with bacteria and parasites, but they do not provide any protection against viruses. Carbon filters are suitable when using indoor tap water.
  • UV filters can remove bacteria and viruses, but they cannot filter out chemicals. More advanced—and often more expensive—UV filters are necessary when using water from outdoor water sources or in underdeveloped countries with lower quality water.

Some water bottles may also use multistage filtration systems, including medical-grade PP cotton, coconut shell activated carbon, antibacterial beads, and medical-grade hollow fiber membranes.

Lid Design 

Filter water bottles have functional lid designs to add to their portability. Screw-on, nozzle, or flip-top lids are common types of lid designs for filter water bottles. Some also have straws and silicone mouthpieces built into the lid for added convenience and easy access to the drinking water.

Most filter water bottles feature leak-proof lids that prevent water from leaking out of the bottle. This is an important feature, especially if you want to toss the bottle into a bag and not worry about any spills. Some lids also have one-touch button locks for extra protection against spills.

Filter Longevity

The lifespan of the water filter depends on the quality of the water and how often the water bottle is used. Most filter water bottles can accommodate 40 to 100 gallons of water before requiring a replacement filter. Water bottles with longer-lasting filters are more convenient because they do not have to be replaced as often.

To clean a filter water bottle, remove the filter and rinse it under water while washing the bottle itself in warm soapy water or putting it in the dishwasher. While water filters do not last forever, many filters are recyclable.

Additional Features

Water bottle design and extra features can be important factors when shopping for a filter water bottle. Filter water bottles come in a range of patterns and colors such as mint, clear, and pink to accommodate different style preferences. There are some made specifically for kids in smaller sizes with fun designs, like sports motifs.

In addition to their stylish appearance, there are filter water bottles with ergonomic designs and molded grips for more comfortable holding. Many are designed to fit into standard-size cup holders, and some also come with built-in compasses, which is a useful feature to have when camping or hiking. Other features include integrated carrying loops and carabiners that make it easy to carry and transport the water bottle.
