Multi Zapper

While the FDA hasn't approved zappers for use on humans or animals, they do accept that electricity can and does kill micro-organisms that may be living in water based conditions such as water, milk, fruit juices, etc. While the levels of electricity suggested by them for use in these processes are far too high for use on humans, lower levels can be effective as illustrated in the video, ParaZapper Works!. In this light, it is important that research be conducted into the use of electricity for controlling and reducing infections in both animals and humans. We will provide a limited number of free zappers for any approved research project as well as some possible additional support. The project must be approved by any agency having jurisdiction over the use as well as by us. The use of ParaZapper™products by several thousand people brings to us certain facts that may be important and answers several questions about zappers and zapping.

Is zapping safe or have there been any claims of injury or harm? It is safe if you follow instructions.
Is it legal for a person to use a zapper? Yes.
Are there any restrictions? There is some advice offered.

ParaZapper™ brand zappers are now available only at Hulda Zapper. This site is here so that you can order our 80 page booklet "Parasite Zapping and the Zapper and to read the postings about health issues.

Although zappers are now only sold for killing microbes in water, the following instructions were from some old information.

Using your ParaZapper

The basic ParaZapper™ is easy to use. Just hold the copper paddles in your hands or use the optional 3M straps. Turn the power on, select the desired frequency, and wait for 7 minutes. When the time is done, turn the power off. Wait 20 minutes and repeat two more times. Under normal usage, the battery should last several weeks to months ( most users responding report 1-2 months in a recent survey).

While some units automatically time the 7 minutes for you, we believe that the timing should be variable according to the users own needs. Sometimes, an extra minute or 2 might help and will not hurt. Some users report zapping for 1 hour a day continuous with no bad effects. Our Manual has additional information on the best and worst ways to zap, as well as information on what to do before, during, and after zapping.

Advanced zappers have a different timing requirement and the instructions supplied with that specific unit should be followed.

Also, as shown in the images to the right, the use of footpads significantly increases the range and effectiveness of the zapper signal.

Image shows that the microbes in the jar on the right are killed by zapping for a 1 hour session, two days in a row.

The cloudiness and color of the control jar on the left shows that there are still living microbes in it.
