Standard Plug and cord supplied with IG-133 series ionizers and DC-2 for 120 volts 60 Hz in North AmericaMost products offered on this site are wired for North America or Japan*, standard 100 to 120 volts 60 Hz. However, the following models are also available for export to Europe, the United Kingdom, Australia, Israel, and other countries:

  • IG-133A
  • DC-2 (DustGrabber™)
  • IG-133DG
  • IG-133DGB
  • The Air Probe Sanitizer with standard 8 inch UV probes will work on any voltage between 120 and 277 volts with no modifications. They do not come with a plug, because they are designed to be hard-wired into your system.
Custom units wired for 220-240 volt 50/60 Hz and with a special plug for those countries are now available from us for only $25.00 (US) per unit extra upon request.

Below are the plugs available for the 220 volt models listed above.

When placing your order, please specify which of the above plugs and voltage you require (minimum of two ionizer products as stated above). EXAMPLE: "Continental European plugs with the 220 Volt 50 Hz option".

(For plugs not shown above, the ionizer can be wired for 220-240 volts 50/60 Hz with a North American plug and then you can purchase an adapter plug.)

The model IG-133 ionizer is not available for 220 volts with the optional plugs shown.

All prices on this web site are in US Dollars, and orders are subject to the exchange rates in existence at the time we process your order. You might visit or or your bank (preferred) for currency exchange rates (which vary daily). We are not responsible for the content of those web sites, which are not in our control.

Some methods of payment we accept are:
VISA credit card MasterCard credit card Discover/Novus credit card American Express credit card PayPal ( Union

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.

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 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 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 must either pay 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 Card ID Number (Security Code):
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.

All overseas orders are shipped via Federal Express International Economy. Please see our shipping info page for more information. We cannot ship via postal mail, unless the international customer pays for the merchandise in advance (by bank check or Western Union) and is willing to accept all risks (including the risk of the shipment getting lost in transit from us to you). We're very sorry, we have had MANY problems shipping by postal mail. We strongly suggest paying the extra costs for Federal Express, as packages sent by them can be tracked and we guarantee delivery.

When you order online on this web site, it is impossible to have this web site's shopping software calculate and display the exact shipping cost to every location in the world. Therefore,  we set it to display $78.50 for everywhere in the world outside North America, and then contact you with the exact shipping costs for your approval.
We used to not display any shipping costs, but then people complained, so we now simply display the approximate maximum shipping cost to places like remote rural jungle areas. Shipping charges are usually much less than that, even to the farthest point on the earth from our location.

You can find out the Federal Express International Economy shipping cost yourself if you wish at Sometimes we are charged a $3.00 pickup fee by FedEx, which is added to the shipping costs displayed on their web site. Most orders weigh two or three pounds.

You are responsible for paying any duties, taxes, or other costs that your country's government may charge. We fill out all customs forms accurately.

* Ionizers used in Japan have a slightly reduced level of negative ion output due to the 20% lower line voltages (100 volts) there.

Various U.S. agencies have sanctions in place that substantially regulate or ban all trade with particular countries, including Cuba, Iran, Iraq, Libya, North Korea, and other countries, persons, and organizations, accessible from By law, we cannot (and will not) ship our products to countries, persons, or organizations listed.
