If you have mold, mildew, or foul odors in your home, an ozone generator may be the solution you're looking for. You may have heard some negative things about ozone, and some of them are true. However, the reality is that ozone can be essential to a healthy environment and does a remarkable job of killing potentially harmful bacteria as well as disinfecting the air. You can create your own ozone generator with things you probably have around the house and a couple of items you will need to purchase. This simple how-to guide will walk you through the steps needed.

Step 1 - Purchase Transformer

Before you can make your homemade ozone generator, you'll first need to purchase a transformer. You need to buy a transformer that is between 3000 and 15,000 V. Most of the time, these types of transformers are used in neon signs. Therefore, visit a local sign shop or other electrical supply store that sells these types and buy one.

Step 2 - Cut Foil for the Large Jar

Cut a piece of aluminum foil so that it will fit into the bottom of the large jar. Make the foil large enough that it will lay flat on the bottom but still protrude up the sides a couple of inches or so.

Step 3 - Place a Strip in Smaller Jar

Just as you did with the large jar, cut and place a piece of aluminum foil in the small jar as well. Again, make sure that the foil rises up along the inside a couple of inches.

Step 4 - Arrange the Jars

Making sure not to move the aluminum foil in the large jar, place the smaller jar inside the large one. Then, take and place them in the center of the 2x2-foot piece of wood. This piece should be laying on a flat and stable surface.

Step 5 - Prepare Transformer

In most cases, the transformer will come with very short lead wires, so, you'll need to strip and connect longer extension pieces. Cut and connect pieces of extension wire about 12 to 14 inches long, and secure connections with electrical tape. Then, connect the other end of the wires to the alligator clips.

Step 6 - Position and Set Up Transformer

Place the transformer on the piece of wood next to the jars. Then, carefully connect the two alligator clips to the pieces of foil inside each jar, one to each strip of foil. No bare wires touch should be touching or there could be an electrical spark and fire.

Step 7 - Plug In the Transformer

Finally, plug the transformer into a wall socket or other electrical outlet. If the transformer did not come with a plug adapter, you'll need to wire one to the transformer and secure the connections with electrical tape.

If your homemade generator isn't responding, you can disconnect the alligator clips and test the leads to be sure your transformer and the outlet are working properly.
