Special order items take longer to ship

We want to make extra-sure you realize that you've added a special order item to your cart. These items take a little longer to get to you because we have to order from the manufacturer first. The "Est. Ship Date" is the date we expect items to leave our warehouse... so add your chosen shipping speed to see when it will show up at your door.

Product Reviews
Rated 5 out of 5 by from Years of reliability I've had one of these filters since it's release, several years now. It's been my go to on backpacking trips, thru-hikes and backcountry hunting trips all over the western United States. I've supported multiple people in all of these scenarios with a single filter. I may have backwashed it a handful of times and still using all original parts... Just ordered a replacement filter and maintenance kit to ensure that it remains my go to for years to come.

Rated 1 out of 5 by from Does not stand up over time I have had this pump for approximately three years. It is only used for a week every summer. I have had a plastics part break twice. First time the pump was still usable, but had to be held by two people to operate. Second break was the clear plastic in the bottle fill lid fitting. The resulted in the pump being nonfunctional. It appears that the plastic parts are not strong enough to withstand use over time. The fatigue and then break. I received a repair part for the first break. Based on the repeated issue I think that I will be looking at other models. Additionally, the on line repair site states that it will be 12 weeks before I get a response. Also, I was unable to upload pictures of the damage (jpg files).

Rated 5 out of 5 by from Easy and fast! We love this filter system for how easy it is to use. It’s light enough for backpacking and very efficient. We’re thrilled that it fits right on to our nalgene bottles.

Rated 5 out of 5 by from Great filter I borrowed one from a friend for the past 2 years. I finally bought one for myself. Compact. Lightweight. Easy to use. Filters quickly. All keys when backcountry backpacking.

Rated 5 out of 5 by from Impressions after extensive 8 years of use I have used approximately 6 different filters from 3 manufacturers. This one is the one I have been using exclusively for the past 8 years.

Rated 3 out of 5 by from Works great until it doesn't I've used the Hyperflow for years, including my PCT thru-hike in 2018. It works amazingly for the first 10 liters or so. Then it quickly gets plugged up and becomes very strenuous to pump. There's no way it gets the 3L/minute after a few days of use. The maintenance manual recommends backflushing every 8L. With a new cartridge, I was religious about backflushing every day or every other day on the PCT. It didn't help. It is a fantastic filter that I absolutely trust with my health, but it requires an incredible of amount of slow, labor-intensive pumping. A previous review says you should be prepared to buy a new $40 cartridge for every trip. I concur with this assessment.
