Pentek US-1500 vs Everpure H-300

[Aquaman]

It is a misnomer to suggest that either the Pentek or the Everpure are superior to one another. The Pentek US-1500 system is capable of using many different cartridges, which makes the comparison impossible unless we agree which cartridges are being used for the comparison. It is also difficult to make a comparison without a point of reference concerning the specifics of the water that is being filtered. Both brands manufacture excellent product, and both brands under the right circumstances can and will do an excellent job of filtering water of the contaminants that their respective cartridges are designed for. As already discussed, there are differences in the maintenance requirements of these systems, but this has nothing to do with the filtration performance. Obviously each system will be uniquely suited to specific situations, but this does not make one "better" than the other.

In response to jjhrae: I think it's possible you are missing my larger point, which is, that in 95+% of all regular residential situations, Reverse Osmosis will produce a purer finished water product than any regular non-RO system. I'm not saying it's the best fit for all situations, or that it will always be the most cost effective choice. I'm simply saying that if you want the purest possible water, then you want RO water. That is an undeniable scientific fact, and it doesn't matter what contaminants, or otherwise nuetral non-water components remain in the water. There will be less of everything in RO water when compared to any other regular non-RO filtration system. That fits my definition of pure water, not merely safe or safer water, but PURE H2O.

In response to One Dumm Hikk: I don't disagree with you, but the discussion was aimed at regular residential drinking water systems. We could also ad an ozone machine, a hydrogen peroxide exposure tank, and a powerful UV light and get safer and purer water, but RO is 95+% pure water. For regular people it's about as ultra pure as it gets. I get your point.

[Aquaman]

I should not surprise you that Aquaman took the time to read the articles at the links you provided, because I wanted to be fair in my approach to this discussion. It didn't surprise me that none of the articles referenced any scientific studies with evidence backing their claims concerning the "harmful" effects of RO water. In fact, at least 3 of the articles were written by, wait for it, representatives of a water filtration sales company that, shock of all shocks, don't sell RO systems, but do sell their own regular filtration system. Send me some links with actual peer reviewed scientific studies, and you will have my attention. Good luck, because there aren't any!

Look, I'm not interested in a debate slanted by the politics of product sales. We @ WaterFilters.NET are dedicated to the SCIENCE of pure water. RO is great, and so are other forms of filtration. RO is, for regular people in residential situations, the purest form of water available, and I'm not saying this to sell RO systems. I frequently recommend regular filtration systems, but if someone asks for the purest possible water, the answer is RO and that is a scientific fact.

I have quickly read through some of these articles. Although there are a few good points, I find that most of the arguments are either false, exaggerated, misleading, or completely off the mark.

I can amplify my points if you care to hear more.

DI water and Distilled Water should never be used for drinking water. As for drinking RO water, it depends on what type of system you are using. A 100gpd membrane has a ~90% rejection rate. A 75gpd membrane has a ~98% rejection rate. The effects of 90% rejection won't hurt humans.

As for people having mineral deficiencies, the only way you could ever prove, beyond any doubt, that it was from drinking RO water, you would have to have identical twins in a controlled situation, where the only difference in the intake of either was the water they drank. Then you would still need a very large test pool to even come close to meeting the standards for scientific proof.

Just because a person has a mineral deficieny and drinks RO water doesn't mean the RO water was the cause of it.

As for the Google search, try searching Google for "RO Drinking Water Beneficial" and read the very first link.

What support you get from Google depends on what support you want to find. I can find links in Google that will tell me Radiation poisoning from an A bomb is beneficial to me if that is what I want to find.

[Aquaman]

Aquaman may not agree with everything One Dumm Hick says (I don't agree with everything anyone says), but I like his style, and agree with his assesment of the "links" to articles written by highly biased persons with no scientific evidence to speak of. If there are any peer reviewed scientific studies on the matter, I welcome them, however, conjecture and overzealous opinions slanted by salesmanship motives are of no value. If RO water is bad for people, then I'm the first one who wants to know, because I would not like to carry the burden of guilt for selling a harmful product. Aquaman has a conscience!

Was jjhrae's posted deleted?

I was going to go back and read his references. MAybe I am looking in the wrong place.

I can also lengthen my links and have Dr's testimonies as well as Previous RO customers who have test results showing their mineral deficiencies, Intensified by their use of RO systems. I could go on, But the Fact of the matter is RO water causes minerals to be removed from the body! This is a Fact as the above stated findings with customers and their health professsionals! I have more proof in my business email and will have to transfer it over to this email address. IF you want to see PHD's testimonies on this subject!

RO should be used on Specific problem waters as I stated in a previous post. NOT for 95% of consumers as it will cause increased health problems As well as Distilled and DI water will!

Everpure systems are Not Basic filter systems, I don't recommend these either, Everpure systems are Certified by NSF and surpass their highest ratings. they work on city or well water applications. There are only a handful of products that can compare to Everpure systems. By the way Everpure also has RO systems I have Only sold 4 in 20 plus years and 2 of those I told the homeowners they didnt need them!

One of those was a Dr and he passed away a few years ago!

jjhrae, (if you are still with us)
I am having a very hard time buying the arguement that RO water is dangerous for your health. Whew! And of course you told those two that they didn't need an RO, you are telling everyone that.
You also posted a link that said that ROs cost $10,000! I wonder if you could elaborate on that?

Also, didn't you imply that there is a lot of wasted water with ROs? Could you please define your meaning of 'wasted' water?
Thanks

Yes, it seems to be deleted.

RO water at 90% purity is actually good for you. It is only when you approach, and exceed, 98% purity that it becomes bad for you.

That would be a rip off The RO/DI unit I have produces close to 180 gallons a day (DIY setup) by using two RO membranes and running the waste out of the first one through the second one.

The TDS out of each RO reads 15-16. After DI, it reads 0 TDS (for my aquariums).

I have less than 200 dollars in the entire setup and I have yet to be waiting on water production.

RO membranes are the most efficient when the waste water to RO water ratio is roughly 4:1. For every gallon of RO water you produce, you get 4 gallons of "waste" water that most people simply run down the drain. I have a holding tank that my waste goes into and I use it in my FW aquarium, water the grass, and to wash my cars with.
