Waterdrop RO Reverse Osmosis Water Filtration System w/ 3 Filters (400 GPD) EXPIRED

My understanding is these tankless systems are actually worse for waste ratio. It has to pump faster to provide proper flow which ends up wasting more water.

Is it a new Osmosis system ?

Quote from ZUKHAN : Based on EWG tap water database, these are the contaminants in my water that are above health guidelines: Arsenic Bromodichloromethane Chloroform Chromium (hexavalent) Dibromoacetic acid Dibromochloromethane Dichloroacetic acid Haloacetic acids (HAA5) Nitrate Perfluorooctanoic acid (PFOA) Radium, combined (-226 & -228) Total trihalomethanes (TTHMs) Trichloroacetic acid Uranium, combined (pCi/L) Other contaminants: 1,4-Dioxane Aluminum Barium Bromoform Chlorate Chlorodifluoromethane Chromium (total) Fluoride Manganese Molybdenum Monobromoacetic acid Monochloroacetic acid Selenium Strontium Toluene Trichloroethylene Vanadium

R/O would be your best bet.

Even EWG is indicating RO is the way to go.

Having said that, it appears EWG is an environmental activist group. Seems to me there is a possibility they need to raise awareness even if it may not be an issue to keep donations coming in.

Some items can not be avoided like trace amounts of arsenic as it is naturally occurring or it is in the atmosphere.

I suggest getting your own test done. Something like https://mytapscore.com.

If you are on city water, they are required to publish an annual water quality report. It should be posted on their website.

One thing that none of these systems mention is chloramines, which some water districts are using now instead of chlorine. This can get past carbon filters,especially the cheap ones. RO membranes will not remove it. In the reefing world, this comes up all the time because chloramines can kill your fish/coral. That is why it is always best to get the latest water quality report from your water district so you know what is in your water.

Wish Amazon sold an installation service with it too

Quote from seawolf : The only selling point I see is less footprint under the sink and leak detection. The rest are gimmick and dubious marketing. https://www.waterdropfilter.com/p...ion-system TDS is a gimmick. You're not going to open the cabinet every pour to check the TDS reading. TDS meters are cheap. 30 day warranty [waterdropfilter.com] - Not a Typo

1. TDS is useful to the agricultural world...its a nice redundant check for them.

2. Since you obviously are a hydraulic engineer explain how a permeate pump is a gimmick, I'm an aerospace engineer and I would love to here your thoughts as I still enjoy learning a thing or two and it been years since I had fluid dynamics and experimental fluid flow courses.

3. Again Ag will appreciate the higher than "traditional" flow....can't stand around for 24-72 hours waiting on your large reservoirs to fill now can you.

4. That's 30 days to return for a full refund if you do want the unit....on the their main page [water-filter.com]....top right, click that little shield with a check mark icon, scroll to the "submit button" and click "GENERAL WARRANTY TERMS AND CONDITIONS"...1 year on product with caveats like most manufacturers .....lifetime on tech support, for whatever that is worth.

I never found any comparisons of this model and others with lab testing so its reviews only....and those are truly useless as you all can see with this thread.
I have 1 for consumption(on city water) and 5 for AG purposes, they just can't come out and call it the the GANJA 400GPD...then you just painted yourself into a corner on sales but with the rash of legalization might not be a bad idea....point is, it makes the water tasteless and my TDS is low like I need for AG so it has worked over a year for me.

This is dead water it'll rot your body away!

400GPD on a system meant to be under a sink? I can almost guarantee that this is super wasteful, plus it still costs more than the (very good) apec systems that you can find on Amazon. I wouldn't call this a deal.

I personally have the apec ROES-PH75, the water tastes great, the ice I get from it is crystal clear, and it only costs about $230. If you're on well water, you'll want a system that has UV, otherwise don't bother with UV.

Quote from Lovinglyfe : How so? There was a study last year that said zerowater was the best retail filter. It comes with a tds.

TDS is a measure of charged compounds in water, uncharged things like motor oil, gasoline, many pharmaceuticals, and pesticides do not contribute to a TDS/ppm measurement. TDS/ppm meters do not detect PFAS in drinking water.

You can have Malathion (an organophosphate pesticide) dissolved into a glass of water 100 times higher concentration than allowed by the EPA for drinking water, and the TDS/ppm meter can still read ZERO.

ZeroWater and their TSD/PPM/000 with a meter is marketing hype.

Thanks. Don't know why they don't make warranty more clear on the product page.
