How to Find a Good Water Purifier

How to find a good water purifier? I guess it depends on what the purpose of the water being purified is intended for hence defining the quality of water needed. Water that is used for irrigation in the Southwest has been treated, but not to drinking water standards. However, water for some industry uses has been treated to such an extent the water is classified as “ultra pure” and the quality is measured in mega ohms. A mega ohm is a measurement of electrical resistance. As you know pure water will not conduct electricity.

So if we understand the following:

1. The intended use of a given water.
2. The quality of a given water before treatment.
3. The budget for a given project.

We can have a good understanding of the situation and avoid any of the hidden pitfalls created by misguided expectations. Some consumers want a Cadillac on a Volkswagen budget and that is not going to happen. The Internet is a good place for those on a moderate budget, but the consumer is left with making the correct decisions on the right application, assembly, and installation. Equipment purchased over the Internet usually has short warranties and if there are problems the buyer has to deal with some sales person over the phone who could be two thousand miles away.

You can run down to your local hardware store, but most big box type systems are mass-produced and come with one-year warranties. If you are treating water that has high hardness, iron, or chlorine issues the typical big box system will start bleeding hardness in a relatively short amount of time. And don’t expect to run down to the local hardware store and get expert advice on water treatment.

In my opinion the best way to find a good water purifier is to search the internet for local water treatment companies and pick at least three to come out and test your water. Have each one give a quote on their top system and also second level system. I would then make sure that they have a contractor’s license and installers who are insured and bonded. Then I would check with the Water Quality Association to make sure they are members in good standing and have gone through some type of certification through the WQA.

I would then compare the three quotes making sure to check warranties, pricing, and the overall customer service you have received. Don’t fall for hard pressure tactics, as a good decision today will be a good decision tomorrow.


Stay away from softeners that have stacked medias inside a single tank. Some manufactures will stack carbon or KDF on top or on bottom of ion exchange resin. Bad idea!

Stay away from magnets. Any softener that claims to soften water without the use of sodium or potassium is typically a scam. There is a media on the market that changes the molecular structure of the calcium and magnesium ion and can reduce the impact of hard water, but I still would not call the water soft.

In most situations always use reverse osmosis for drinking and cooking water.

Troubled well waters will usually need more than a softener to produce utility grade water. Hydrogen sulfide, iron, manganese, tannins, bacterial contamination, turbidity, acidity (low Ph) are just some of the issues involved with troubled waters.
