Ionizer Brand Comparisons Which is the best air purifier? How do you choose the right one? This page provides clear information that shows you how to compare between all the different brands and types of home ionizers and other types of air purifiers yourself.

Have you seen the false advertising and misleading statements? There are several misleading product ads and product names that imply that their 'ionizer' actually puts out a breeze consisting of high-density negative air ions, when that is not the case. Before you buy, read their manual, catalog, package, etc. Do they say that their product actually emits large numbers of ions externally (in the millions or trillions)? Our products do. Several other 'air purifier' products claim to be negative ionizers, but are in fact really ozone generators. Yet other "ionizers" do generate some negative ions, but they do so internally; few ions ever leave their unit and go out into the room. And as unbelievable as it may seem, some even put out positive ions. And some use chemicals, perfumes, or agents. None of our products do; check before you buy one. During the first week of December 2002, we carefully tested two different models of nationally-advertised, column-style "ionizers" being sold in a nearby retail store, using a very sensitive negative ion detector. The negative ion output reading from either unit was zero. But we could walk outside and easily detect negative ions that were normally present that day outdoors. A close examination of the instruction manuals (and also another brand of 'air purifier' of similar appearance that was not tested) revealed no claim to actually emitting negative ions; only ozone.   Our products also feature: High ion output and high negative ions per cc while almost undetectable levels of ozone Compact design Low power requirements   We occasionally receive e-mails like this asking "how do your products compare to..." other ionizers made by other manufacturers. We do not consider it ethical (nor would anybody believe us!) to immediately say that, yes, ours are better than a certain brand. But the comments from people who've bought them speak for themselves. And there's already enough info on this web site that says why we believe ours are superior and longer-lasting.

THE LATEST DECEPTION TO PROMOTE INFERIOR "AIR PURIFIERS" ... are web sites masquerading as non-profit, impartial comparisons for the benefit of people shopping for the best value. By listing competitive brands and models together (besides the one that is actually trying to be promoted by the web site's owner, which is usually at the very top of the list), they appear to be impartial. Not so. There are even pages on these sites that offer information and advice, in an attempt to appear credible. But some of this info ranges from just being technically inaccurate to downright false and misleading. For example, negative ionizers (which have been scientifically proven through the years again and again to be the best, if properly designed) are presented in a bad light with many disadvantages and drawbacks. It is not difficult to see through this unethical and deceptive selling technique, with these thoughts in mind.   We think our IG-133- models will outlast any other ionizer available. That's a bold statement, but we believe it is the truth for several reasons: 1. All ionizers have an ion emitter, and all emitters wear out. But our emitters are either user-renewable (details on our site) or, for $29.95 extra, extremely long life. In any case, they are replaceable; they just plug in. 2. We've seen many ionizers that build up a coating of dirt inside that makes them stop working after a relatively short period of time. But ours are designed to have the dirt build up on the outside so it can be cleaned off easily. 3. The electronics inside the ionizer is not only a reliable design, but quality built. 4. We still have, and use, the first ionizers we've ever made. And they still work like the day we built them, even though they have been in almost continuous operation for years. 5. We have a 60-day money-back trial period on all our products. But very few (maybe one in a hundred) are returned to us asking for a refund. 6. We have a five-year warranty. But only 3 or 4 ionizers have ever been returned to us because they failed. And we think some of those failures were due to power surges from lightning, but we exchanged them with new ionizers, anyway.
