When choosing a water filter bottle, you should consider your budget, how much water each bottle can filter before a replacement filter is needed, and whether you want a portable version or something to use at home. There are also bottles made from various materials, and some are more durable than others. You might also consider certain materials if you will be using the bottle for travel, since some are safer and more reliable for travel than others.
One factor you should consider when searching for a water filter bottle is the price you can spend. Some have higher-grade filters than others, and these tend to cost more. That doesn't mean that lower-grade filters won't improve the taste and health of your water, so if you can't afford a top of the line model, you shouldn't worry. Larger bottles are also usually more expensive than small travel-sized ones.
You should also consider how many refills of water each water filter bottle can handle before you will have to replace the filter or cartridge. Some offer more than others, and this is often linked to the quality of the filter and bottle, although this isn't always the case. Read each package carefully to determine how much you'll be getting for the price before you buy. A bottle that costs a little more but offers dozens more refills than a cheaper model might actually be the better value overall.
There are also various water filter bottle sizes you can choose from. Some are large enough to hold multiple servings, so you have enough for an entire day or longer. Others are travel-sized and are roughly the same size as the average plastic water bottle. When choosing which type to buy, you should consider which is more likely to be useful in your daily routine. If you don't travel very often, a larger bottle might be more convenient so you won't have to keep refilling throughout the day.
You should also keep in mind that some materials are better than others. If you will be traveling by car frequently, you might consider a metal or glass water filter bottle, since they won't release chemicals when heated in the car. Many are also durable, so they're less likely to crack or break during trips. Plastic bottles are also handy for various reasons, since they are typically lighter weight and easier to carry.
