In the comparison chart below you'll find alkaline water ionizers compared . Pay special attention to:
1) Filter replacement prices. Every 6-12 months you'll want to change the filter and many (or should I say most) water ionizer manufacturers overcharge. This "after purchase" replacement needs to be factored into your purchase.
2) Warranty Terms. The Warranty (return policy in short term) and Guarantee terms (longterm reliability) are usually reflections of the quality and durability of the ionizer brand. Be careful of terms which indicate "Pro-rated". These can often mean paying money when it comes down to having it repaired if needed.
3) Quality. Without taking each Water Ionizer apart it's hard to determine how well they are made (Hence this website!). Look for certifications such as ETL, UL, or CE which can be an important criteria determining quality.
When it comes to alkaline water ionizers compared the question most asked is:
"Are the less expensive ones as good as the $4,000 models?"
Just because the Kangen water ionizer machine (I call it the Grandfather of water ionizers) runs close to $5,000 doesn't mean that you can't get a Water Ionizer just as good - for much less. Kangen is a quality made machine which uses some of the older technology along with some of the best materials. With it's high price tag you have to factor in the Multi-Level Distributor commissions. At one point they were just about the only water ionizer available.
Several manufacturers wanting to break into the industry are bringing better technology and a lower price to the market, especially since the demand for Water Ionizers has grown in the U.S.
Several certification standards exist that determine quality of design and of electrical components:
UL Certified - Underwriters Laboratories Inc. (www.ul.com) is an independent lab that writes testing standards and tests products for safety and certifies them.
CE Certified - The European Commission describes the CE mark as a "passport" that allows manufacturers to circulate industrial products freely within the internal market of the EU. Most products covered by New Approach Directives can be self-certified by the manufacturer and do not require the intervention of an EU-authorized independent testing/certifying company (notified body).
ETL Certified - A product bearing the ETL Listed Mark is determined to have met the requirements of 200 prescribed product safety standards.
What I especially like about the ETL certification is the mark indicates that "the manufacturer's production site conforms to a range of compliance measures and is subject to periodic follow-up inspections to verify continued conformance".
The fact that most water ionizers are made in the Orient means that safety can be a issue, as their standards are much lower than ours.
