    I hope to shed some light as I have worked in this industry for several companies. To those who are worried about it being an unknown brand: the filter media design and material are going to be the same in all these straw tube-style filters. They are extremely cheap to manufacture but early adopters and well known brands charge more because they market better. They should not effectively expire if they are kept out of damp or humid conditions. On that same note, best practice is to back flush with clean water after use or every 20-30 gallons during active use as the media does plug up and contaminants need to be released. Always shake them dry between use and don't store them in something air tight.
    Sorry, that was long winded.

    Is this a well known brand? I'm unfamiliar.

    Edit: not well known. some apologists in the comments claiming they are all the same...which is a weird claim for safety equipment.
    the business address is a residential house. always a little sketch.
    the name is hard to pin down. one nearby company does provide filtration for lab equipment but doesn't list this item on their website.
    YMMV/Buyer Beware ...which for any safety/emergency equipment is an immediate pass for me.

    I see it's being promoted by a Paid SD Staff Influencer...is this an affiliate? paid advert? any vetting/communication with the company to clear up the concerns? it's been pushed to Frontpage now. I also wonder if the phrasing "sharing this deal" is meant to be a CYA rather than claiming to have "found" this deal like some other posts or if it's just DE style choice

    Edit 2:

    Be advised that these are not the well known life straw brand. They are even made with the same color etc to make people think they are life straw at first glance. They may work ok, I don't know. However when it comes to potential lifelines I try and stick to what I know I can trust. You don't skimp on those types of things.

    Everyone should have one of these. They are cheap, (especially with this deal) small, (easy to store) and could save your life in an emergency.

    After this purchase just now to add to my 5 already in storage, I have 9 total. Got in for the same price about a year ago on same 4 pack. Not only good for emergencies, but for wherever you want to go without taking water with you. Whatever water you can find from wherever (except non-diluted urine/salt water) this will make it perfectly drinkable and safe instantly. BTW, One gallon of water weighs 9 lbs....think about that....These things are worth their weight in gold to be honest if you stop and think about. $3.75 per straw can keep you comfortably alive for 4 years straight at one gallon of filtered water per day. (each filter good for 1400 gallons). The 4 pack for $15 can do it for 16 years straight. Cheapest life insurance you can buy for uncertain times...

    On Amazon there's also a link for the "newer model". What's the difference and do they "expire"?

    So I looked at lifestraw and it seems to filter only 0.2 micron while these can filter 0.1 micron so the posted one should filter better

    The LifeStraw brand claims NSF Certified, these don't.

    So you are going to think that some Chinese purposely fake looking filter is better than a well known proven brand based on what they post?? Ugh….,

    Not going to trust my life or families on some unknown Chinese imposter brand that purposely attempts to make people think they are legit life straws. They are intentionally trying to be deceptive. Just my opinion based on field use in 8 countries and having my life depending on a water filter.
