Buying Guide for Emergency Water Filters

There are a lot of aspects to consider when selecting the right emergency water filter for your situation.

#1 Budget

First and foremost, it is important to think about your budget in terms of which water filter will work best for you. Do you have a lot to spend on a top of the line model, or are you looking to keep your purchase under thirty dollars? Your budget will help you choose the area in which you need to look for the perfect emergency filter for your needs.

#2 Plans

If you are an extreme outdoor enthusiast, you may need a larger and more permanent filter model than you would if you simply take a few hikes every now and then. Survivalists looking for the most extreme primitive adventure may prefer to work with smaller and more portable water filters, while those who will be camping in one spot for a long time might do better with a larger option.

#3 Strengths

Depending on what you are looking for in a filter, you may choose one with certain strengths over a different, comparable model. A filter that is lightweight and portable may be best for adventurers who do a lot of hiking.

However, a sturdier product may work well for anyone looking to spend weeks out on the trails or lost in the woods without the promise of clean water in the near future.

#4 Brand

Brand name should never be the only deciding factor when it comes to choosing the right filter for your emergency and survival situations, but it is important to keep it in mind.

A product with a popular brand name may have better customer service, but it may be more expensive than an off-brand, generic product. Weigh the pros and cons before making a final call.

#5 Reviews

It is always important to see what other customers are saying about the products you are interested in purchasing. It may seem obvious, but you should probably not stake your clean water on a product that only has a few good reviews!

Rather than simply looking at the positive and negative reviews, however, be sure to consider the number of reviews as well. This can show you how many people have purchased the same products, and may help sway your decision.


It may seem like a daunting task to choose the right best emergency water filter for your needs, but rest assured that you can make the right decision easily when you consider this simple buying guide.

Check out the top five survival filters on the market today, and choose between these products based on your budget as well as your size and filtration needs.
