# MSR Thru-Link Inline Backcountry Water Filter

The MSR Thru-Link Inline Backcountry Water Filter is designed to connect to a hydration reservoir for drinking while moving. Its hollow-fibre and activated-carbon filtration approach is suited to hikers who want an inline setup, but the listing gives two different flow rates that should be clarified before purchase.

## At a glance

- Designed for inline filtration with a hydration reservoir, rather than a separate pump-based workflow.
- Quick-connects are claimed to work with any hydration reservoir system on the market.
- Manufacturer states the hollow-fibre filter meets NSF protocol P231 for protozoa and bacteria removal and treats up to 1000 liters.

## Pros

- The inline design lets hikers drink through a hydration system without stopping to filter into a separate container.
- Manual operation avoids a powered filtration setup.
- The listing includes both hollow-fibre membrane and activated carbon in its purification method.

## Before you buy

- The listing is inconsistent about flow, stating both 1.2 liters per minute and a maximum of 1.5 liters per minute. It also gives dimensions as 19.1L x 4.1W x 4.1H centimetres and separately as 19.05 x 4.06 x 4.06 cm; 70.87 g. Confirm the applicable specifications for the selected listing. Compatibility with reservoir systems and the stated treatment claims are manufacturer claims, not independently verified here.

## In the box

- Filter (Included)

## A good fit for

- Hikers and backpackers who already use a hydration reservoir and want inline filtration while drinking.
- Buyers seeking a manual filter with stated hollow-fibre and activated-carbon elements.

## Less suited to

- People who need a standalone filter with its own water container, since the product is presented as an inline reservoir filter.
- Buyers who require one confirmed flow-rate or dimension figure without resolving the listing’s inconsistencies.

## Customer feedback

The supplied evidence contains aggregate ratings but no customer-comment summary, so it does not establish what buyers praised or criticised. The rating distribution is mostly five-star, with ratings across the other star levels as well. Treat that as a broad signal rather than evidence about flow, reservoir fit or filtration performance. Those details matter for an inline filter intended for use while hiking.

## Frequently asked questions

### How is the MSR Thru-Link intended to be used?
It is designed to connect inline with a hydration reservoir so water is filtered as you drink. Confirm that your reservoir connections are compatible.
### What filtration method does the listing specify?
It lists an activated-carbon and hollow-fibre membrane method, and the manufacturer claims P231 performance for removal of protozoa and bacteria.
### What flow rate should buyers expect?
The listing gives both 1.2 liters per minute and 1.5 liters per minute. These figures conflict, so verify the applicable rate before buying.
### What comes in the package?
The included-components field lists a filter. The package is described as a cartridge.
