General Ecology Deluxe Replacement Canister Reviews:
Economic Water Filter
My last filter did not last long, but I think that is my fault. I think I let it freeze with moisture inside it, cracking the carbon block filter. I like the easy clean feature of the new design. It has to make backwashing easier. The gravity feed feature is handy and the hose fits the bottom valve on a two-gallon collapsible water carrier. The price has gone up a little over the years, but it works and it does provide your first need.
Great purifier. Have used for years with no issues. Only way this failed a dye test after a couple of uses is if it was dropped. It is ceramic so you actually have to read the warnings and treat it with a due amount of care. Do so and it will give you years of enjoyment.
I have the same First Need pump that I bought 20 years ago. The filter canisters still fit it. Easy to use. Easy to replace filter canisters. Never had a problem with water-borne diseases after getting this water filter. You can get lighter water filters but you can't get a better one.
i have had two in the past 20years and i will always stick with the first need water pump. it is the best around we use it for the Boy Scouts. two weeks ago we went on a 4 day trip and pumped at least 20gal. and it is still going strong.
My replacement canister was easy to install pumped water effortlessly and extremely fast. I have used a fist need on a NOLS course w/o any problems after 30 days in the field. My replacement canister served me well on a recent 4 day canoe trip in the Adirondaks.
I used this for a Boy Scout backing trip @ Philmont NM. Worked great kept 12 people hydrated for 10 days worth of hikeing. Water tasted great. Cool water from streams always better than warm from tap provided by BSA.
I heard great things about this filter. I used it threee times in clear streams. The last time I used it both myself and my friend got sick as dogs. Did not think anything of it at the time. But just pulled it out for a trip and did the "dye test" and it failed. Guess I know why we got sick!
