Reduced Prices

Now with IEC power connector
instead of non-removable cord.

220 volt Ionizer with IEC connector on black IG-133A

Lets you supply your own power cord with
the plug you need in your country to save money.

Cords may be available for little or nothing
 at your local computer repair shop.

A Black model IG-133A-BLK negative ion generator shown above.
This new feature is also available on other models and color.


The following 220-240 volts 50/60 Hz models are available for export to Europe, the United Kingdom, Australia, Israel, and other countries:

  • IG-133A-220V (black or white)
  • DC-2-220V (DustGrabber™ only)
  • IG-133DG-220V (ioniser with built-in DustGrabber™, in either black or white)



here is no longer an extra $25.00 charge for these 220 volt models, if you would rather supply your own power cord*.

   Instead of the cord (with special plug) that could not be removed, these ionisers now are supplied standard with an IEC connector (like on the back of computers and monitors) as shown above. Check your local computer repair shop; they may have a cord for the asking.

* All international power cords (with non-North American power plugs) are much more expensive when purchased by us here in the USA, than in your own country. This new design has been requested by many overseas customers to lower the price for 220 volt ionisers.

The special IEC power cord with the required plug for most countries are available from us for $25 per cord extra, if you request them. Otherwise, all 220 volt ionizers are shipped without a cord (as shown above) now at the same price as 120 volt ionizers.


Cords available for the 220 volt models listed above are shown to the right.

All these come with a IEC connector on the end opposite the plug.

Besides these ionizers, the Air Probe Sanitizer will work on any voltage between 120 and 277 volts with no modifications.

* Most IG-133-series ionizers on this web site are wired for North America or Japan, standard 100 to 120 volts 60 Hz. Ionizers used in Japan have a slightly reduced level of negative ion output due to the 20% lower line voltages (100 volts) there.

Why we take these precautions

  A few years ago, a person in eastern Europe ordered an ionizer from us. We e-mailed back and forth, and as he seemed honest, we shipped the order to him.
  However, the credit card company later informed us that he used a stolen credit card.
  Who do you think paid for that order? Not the person who owned the credit card. And not the customer. We did, friend.

No overseas orders can be shipped to other than the billing address of the credit card. In order to protect against credit card fraud, we must verify all billing addresses of all orders shipped.
Some countries will not verify a VISA/MasterCard credit card billing address. If your country or bank is one of them
*, then we usually cannot accept a VISA/MasterCard credit card payment from you. American Express Credit CardWe can ship to almost anywhere in the world if you pay by American Express, because American Express verifies the credit card billing address in any country in the world.
* Some countries that will not do a billing/shipping address verification with VISA or MasterCard are the United Kingdom, Australia, France, and Israel. Customers in these and any other country where we cannot verify the billing/shipping address of the credit card may be required to pay by using an American Express credit card, send us a check in advance, pay by Western Union, or pay via PayPal and we can ship to your confirmed PayPal shipping address. Sorry.


We also need the credit card ID Number...
Card ID number locations on AMEX (front of card) and VISA/MC (back of card) credit cards. This helps verify that the customer actually has the card.
to help guard against credit card fraud from stolen cards.


We DO NOT SHIP to these and some other countries.
high-risk countries

We no longer accept credit cards or checks from any of the countries listed in the "High-risk countries" chart. Sorry, too many Nigerian orders have been placed attempting to use stolen credit cards or fraudulent checks.
