How much water is wasted per gallon to filter the water? I noticed the 6-stage was 2:1 (it said: only 2 gallons wasted for every gallon)

Since July 2014, a Water Detector is included in tool kit as free gift. The main use is to alarm for water leak. If you use a reservoir to collect and reuse waste water, the probe can be used to alert you when it is full. A 5-gallon bucket (sold at HD for $3) would usually be good enough as most family don't consume more than 2 gallons of RO water. iSpring Water Systems | (678) 261-7611 M-F 9-5 EST | sales@ispringfilter.com

real-world test here (yes I measured). To fill the tank from empty, it's about 2.5:1 (2.5 gallons waste to 1 filtered). BUT once the tank is full and you draw a glass from it, the ratio jumps to 5:1 (5 gallons waste to 1 purified), this has to do with the filling tank creating back pressure and allowing less water through the RO membrane. These systems (RO in general) are NOT efficient!!

The ratio is the same, 2:1. Las Vegas's water rates are $1.16 per 10 thousand gallons. If you are paying comparable rates, it comes to about 2 cents per 10 gallons of filtered water. I've been using my system for a year now and probably should change the filters. The ppm reading out of the tap is 443 and 51 from my 5 stage system. I'm satisfied.

I think the guy in Los Vegas is full of it. If not they waste a lot of water that California would pay dearly for. Ours (mid Kansas) is 1.91 per 1000 gallons. That is 16 time more expensive than he is stating and that equates to 3600 gallons of wasted water per month unless it actually does shut off the flow when the tank is full. I see no mechanism that would do that unless there is a high pressure shutoff somewhere.

Follow the chart on the back of the container as it gives several different ratio of ounces per gallon depending on what you are trying to control. I personally have used anywhere from 2 to 6 ounces per gallon. Does a great job.

I just got a syringe and figured that 2cc was the right amount for 1 gallon of water. if this is a wrong compilation please let me know!

That depends on the membrain that the R/O system uses but a typical 50 gal per day membrain is a 4 to 1 ratio. That is it wastes 4 gallons for every one that it produces. If you go to a 100 or 150 gallon per day membrain they will waste less water but they will also produce water that has a lot more disolved solids in it (less filtered). We use the standard 50 gallon per day membrains unless someone asks specifically for something else.

Hello, the unit can use up to 4 filters at a time, each one has a life of 3,000 gallons, I hope I helped you, have a nice day.

I use 1/2 ounce, per gallon as a good rule. The manufacturer suggests 1oz per 2 1/2 gallons.

Interesting question. I wanted to know so... Let's say your unit costs 180. 2 of the filters are good for 6 months (HF-31, HF-33), and 1 filter is good for a year (HF-32). From page 5 of the manual, "The period for filter exchange is based on 0.5 gallons average use per day". So, I believe cost per gallon for the first 6 months would then be .5gal/day*180 days = 90 gallons @ 180, in which case your price per gallon is 2 bucks. Your costs would go down from there since you wont have to factor in your one-time equipment cost, just the filter replacement cost.

That depends on the rate of filtered water gallons used and proper use of the filter system. Warm/hot water will ruin the filter if allowed to run through on filtered setting. If one person is using the filter for drinking/cooking purposes at a rate of 1 gallon per day, the 200 gallon filter will last you 200 days. Additionally, if two people are using the filter for drinking/cooking purposes at a rate of 1 gallon each per day, the 200 gallon filter will last 100 days. So, just approximate the number of people using the filter system, multiplied by the amount of filtered water used by each person per day, then divide into 200.

i thought this can only filter 25 gallons? I'll have to go back to my manual to verify. 265 gallons seems like way too much. even my bad ass water filters on my fishtank can't do that many gallons.

It will ALL depend on your water quality. You should be able to hit that (or better) pretty easily. I am in the Houston area (nasty municipal water supply) and I am getting about a gallon every 3.5 minutes. Also depends on how often you clean your filters.

We use the black filters and I believe it's 3,000 gallons each. They say to multiply the filters times that. So I have two filters. We get 6,000 gallons till need replaced. We also use fluoride filters and I believe those are 1,000 gallons. As far as not removing chlorine that's bogus. It removed bacterias, antibiotics,lead,chlorine etc. that's why it is good for survivalists because u can put swamp water in it to make drinkable.

The tank holds 1 gallon. I use filtered water, and so did not install the provided filter (which uses up some of the volume).

It says 100 ml treats up to 50 gallons of water so I would assume 2 would be too much. I use 100 ml for 46 gallons and the tank is sparkling and only water changes every 4 or 5 weeks

You need a little less than 3 grams for 1/2 gallon of water, which is about 3/4 tsp, or a heaping 1/2 teaspoon, or a loosely-packed teaspoon. Going by weight is best, but I don't bother. My plants are doing great.

Uses 4 filters at once, so it filters faster. Each filter filters 3000 gallons (I called the company to confirm by the time I want to purchase it). So, just change the filters after 12,000 gallons filtered. Another tip I wished I knew before, be patience with the taste. Just after three full filtration I finally got the amazing and fresh water taste. I have been using it for about two month for all the cooking and drinking, love it. It is worth each dollar and all the research I did.

The ProPur dome filters are rated to filter an average of 3000 gallons each. For a family of four using a gallon of water per person, per day, that equates to a little over 2 years per filter. A 2 filter system would last 4 years.

It comes with filters (I think 2) that you can use right off. I purchased filters when I bought it because I was not sure either. The instructions state that you should change the filter after so many gallons poured through. So depending on how often is it used that would help to decide what filters to have on hand.
