As an avid backpacker, you know that staying hydrated on the trail is essential. But with so many water filter options available, it can be challenging to decide which one is right for your needs. In this guide, we’ll explore the different types of backpacking water filters and what to consider when choosing the best one for your next adventure.
Types of Backpacking Water Filters
There are three main types of backpacking water filters: pump, gravity, and squeeze.
Pump Filters: These filters use a hand-operated pump to force water through a filter cartridge, removing impurities and debris in the process. Pump filters tend to be the most effective at removing bacteria and viruses but can be bulky and time-consuming to use.
Gravity Filters: These filters use gravity to pull water through a filter cartridge, making them ideal for large groups or base camp scenarios. They are relatively lightweight and low-maintenance, but they can be slow when filtering large volumes of water.
Squeeze Filters: These filters are similar to pump filters but are more compact and lightweight. They use a hand-operated squeeze bag to force water through a filter cartridge, making them ideal for solo hikers or small groups. Squeeze filters are not as effective as pump filters at removing bacteria and viruses but are still a good option for most backpackers.
Factors to Consider when Choosing a Backpacking Water Filter
When shopping for a backpacking water filter, consider the following factors:
1. Water Source: Before choosing a water filter, consider the quality of water you’ll likely encounter on your trip. For example, if you’ll be hiking above the treeline, you may encounter pristine mountain streams that require a more robust filter. Conversely, if you’ll be hiking in areas with human or animal waste, you’ll need a filter that can remove harmful bacteria and viruses.
2. Filter Lifespan: Pay attention to the filter lifespan, which can range from 500 to 5,000 liters or more depending on the model. If you’re planning a multi-day backpacking trip, consider a filter with a longer lifespan or bringing multiple filter cartridges.
3. Weight and Size: The weight and size of your water filter are crucial factors, especially if you’re hiking long distances. Look for models that are compact and lightweight, such as squeeze filters or gravity filters.
4. Maintenance: Consider the maintenance required for each filter type. Some models require regular cleaning or backflushing, while others require no maintenance at all. Choose a filter that matches your preferred level of maintenance.
