Has anybody tested this system with a TDS meter? That is the only way to really know how good of a job it is doing. If the reading is 20 or less, then it is comparable to an RO filter. If it's much higher than 20, don't waste your money. Has anybody tested this system with a TDS meter? That is the only way to really know how good of a job it is doing.

A TDS meter is NOT "the only way to really know how good of a job it is doing" from the Zero Water FAQ they explain that Zero Water does not remove Fluoride, Bacteria, Arsenic, Phenol, Cryptosporidium. The TDS for the most part measures electrolytes (salt, minerals, etc). By the way, if you remove all those minerals they just get sapped from your body via osmosis. Google "drinking distilled water"

I tested it with the meter and saw very little in difference in the number. I took it out and replaced it with a zero water pitcher. Big difference. I'm sold on zero water. By the way the reading was 62 with the brondell from 68. Marietta Water

Yes I did test this system with the TDS meter and was very disappointed. The readings were exactly the same as what came out of the tap. I called Brondell and they informed me that was how it's supposed to be. Their system is apparently designed to only remove the bad taste...not the dissolved solids...well in my case it did neither. The water still tasted bad and the TDS reading was just as high as the tap. Our water is so bad here, typical readings from 450-800+ so it may just be that filters don't work here. I gave up on filters after trying many and ordered delivered water from Culligan. Yes I did test this system with the TDS meter and was very disappointed.

I have tested few times in the past month. There is no change at all in the reading - ~ 350 before filtering and ~ 350 after filtering.

I think it depend on Water piping and your management.Never throw hot water to RO filter.But RO system basically&#12288;waste water,and in my case,this system worsen TDS(Total Dissolved Solid) .I think we'd better use drainage water to gardening or such a daily water(not for drink).i don't recommend this system.

Your use of the number 0.1% would indicate you're looking for a high level of accuracy. I figure the meter is good for two or three percent plus or minus. I use mine to detect roof leaks. Six to 10 is no leak and 18 or above is a leak. Of course, as stated in the meter description, it'll measure zero to 99%. May be I don't fully understand your question!

One could worry about the exact accuracy of this device, where I feel it is more a relative reading, and tells you the approximate amount of solids remaining in the water. For the most part, after filtering the water, the ZeroWater device reads zero.

The membrane is doing almost all of the filtration. Most RO membrane last 2-8 years depending on your water quality and water use. If you have soft water they last longer. Get a TDS meter and test your water, if your raw water vs. treated water is below 80 % removal of TDS change the membrane. The indicator light should tell you if the membrane is bad if it tests TDS.

According to the website, they seem to have no idea."A. ZeroWater filters are not certified for the reduction of fluoride however fluoride is an inorganic compound. The TDS meter is designed to detect inorganic compounds. Fluoride levels in water are usually around 2 to 4 ppm, which will show up on the meter as 002 to 004. So when filtered water reads 000 it is not likely that fluoride is present in water."That's why I want one, too. To protect my teeth and precious bodily fluids.

Well, in practice it gives a display at speeds up to 34. How much time lag and how accurate it is relative to the changing bottom I don't know. I also don't know the sample rate. But yes, it'll give you a depth reading at speed.

Hello,Mine is measuring 3.88 on average. If I were you I would reset and then see where it goes. Twenty five sounds outrageously high. I would check it again then if the numbers are still that high I would buy one of those radon detectors that you mail in to compare the readings. I love the unit I bought as I can move it to different places. I have reset it a few times but overall it seems to be working quite well. I really hope those readings are bogus and that it just needs to be reset. If not you will have to have a system put in for remediation.

The life of the filter will vary based on the level of TDS in your water. You should change the filter once your meter reads 006. On average a filter will process between 25-30 gallons of water. The less TDS your water contains, the less often you will need to change your filters.

I get a different reading from every gauge I use. . .TD seems consistent between tires, though. Maybe battery?

Two years is the nominal service interval for these. The best way to monitor the performance of these is to use an inexpensive TDS meter to ensure the membrane is removing greater than 85% of the total dissolved solids from your water. Depending on the water you are treating and prefiltration in your system and water pressure you may be able to get 5 years out of your membrane, or less than two. Get the TDS meter, you will have fun monitoring the performance of your system!

There is a sticker to put on the filter that is time sensitive. It will tell you time, 6 months, 12 months.An easy way to test your filter is to test your water with an TDS meter. The aqua pure scale inhibitor will add about 50 ppm TDS to your water when working. This is a good meter: HM Digital TDS-4 Pocket Size TDS Tester Meter Without Digital Thermometer, 0-9990 ppm Measurement Range , 1 ppm Resolution, +/- 2% Readout Accuracy

I just tested it with my meter and with a Brita filter in it ....The TDS....it came out 77PPM

All I know is that it filters out just about everything but the water itself. A TDS meter comes with it, so you can measure your filtered water against your tap water. The filtered water should show 000, while the tap water may show 122 or something else. I can give you the phone number of the manufacturer of distributor (not sure which). It's 1 800 503 2939

Hello Nick, what are you using it for? I am using it for the pool and it is very accurate, but you do have to convert it from Parts Per Thousands to Parts Per million, so it will appear very low on the meter. Bob

So what is your question. I am no expert on pool filters. I have had this filter since I bought my first pool, so my experience lies with this brand only. I know others who have the 30 and 40 series versions. This filter compared to those others is top of line. I am extremely happy I have and am using this filter. I have a 24 ft round - 52 " wall pool and this filter is more than adaquate to handle the size of my pool. I dont know what your issue is with the clamp on top, but as long as you follow the directions for tightening the band up, you should be fine. Tip- I use a rachet set with a deep bit to loosing and tighten the clamp. Open end adjustible wrenches will strip the band belt bolt. So what is your question. I am no expert on pool filters.

Given your results I suspect you are using pH paper or test strips which can be off by a full point or more when testing RO water because the water is so pure. I suggest you get a good digital pH meter to test the water's pH. Remember to test the water in a way that represents normal use. A brand new system will test more acidic than a system that has broken in and is fully pressurized. Using a TDS meter is an indirect way to infer that the system working correctly. Test the water as it leaves the RO membrane and at the RO faucet, and then compare those to the tap water. Remember, the system adds calcium and magnesium minerals which both increase the pH, and increase the TDS.
