Lifestraw Filter Breakdown

The award-winning cartridge comes in two parts. The second part of the filter is optional:

Stage 1: 0.2 micron hollow fiber membrane which removes protozoa and bacteria that often saw in streams and lakes.
Stage 2: Activated carbon filter which reduces the taste and odor of chlorine.

The hollow fiber membrane filter can operate independently without the activated carbon filter.

Cartridge Lifespan: 

There has been a confusion on the lifespan of the stage 1 filter of Lifestraw on whether it is 1000 or 4000 liters.

According to Lifestraw, 1000 liters is the minimum tolerance level of the test conducted. However, the actual lifespan can be up to 4000 liters.

We do recommend the filter to be changed every 1000 liters as we are filtering bacteria and parasites.

Stage 1 average cost per gallon: $0.027
Stage 2 average cost per gallon: $0.25

Verdict: Recommended

Lifestraw has been trusted by many for its durability and quality. This water bottle filter is cost effective and easy to bring along on any occasions.

How to Pick a Purifier Water Bottle?

Choosing the right purifier water bottle is not a difficult task. You just need to nail down a few aspects of the selection process.

Here are 4 criteria that I use when choosing the best filtered water bottle.


What is the main purpose of getting this water bottle? Are you using it for outdoor activities such as hiking, camping and surviving?

Outdoor activities: You will need a filter which removes bacteria, protozoan even virus to prevent intestinal infection.

You will need the same filter if you are traveling to least developed countries where the cleanliness of water is questionable.

Indoor Water Source: Majority of the urban water source is contaminated with chlorine.

You practically don’t need an expensive filter which filters virus and bacteria. A simple carbon filter is able to do the job.

Filtration Capability

The cartridge is the heart of the whole system. In most cases, we will pick the filter which removes most of the contaminants.

If your water source is only contaminated with chlorine, you can look for a carbon filter.


The cost of the water bottle includes both the initial cost as well as the maintenances cost.

Beware of cheap bottles, it might be poorly designed and leaky as well as incurring huge maintenance cost.

We break down the ongoing cost for every bottle that we analyze.


Durability is one of the things that we need to look for on a filter. We want to have a purifier bottle that can lasted 5 years.

But how do we know whether it is durable?

Read the customer’s review. Avoid leaky bottles as it will create a lot of problems in the long run. It might damage your belongings too.

Say no to plastic bottled water. Filtered water bottled are more environmentally friendly and it is reusable. Single-use bottles will fill up the landfill and release a toxic gas that affects our health.

Let us know in the comment below if you need additional information on the filter that we mentioned above.
