Here is a review I did on the Sawyer Squeeze. I have no financial connections with Sawyer, I have only bought and used this item.

Sawyer Squeeze review

One thing I failed to notice, until someone else pointed it out, is that the way I use the washer to backflush, I would probably contaminate the clean water, unless I cleaned the washer first, like with boiling etc. Just something I overlooked in the video.
