How to Make an Air Purifier (That Actually Purifies Air)

Air Purifiers are pretty important things to have in your home. Whether you live in an area with a lot of air pollution, suffer from asthma, or even have a lot of allergies, an air purifier can help you out.

However, they can be quite expensive to buy, and not everyone is able to make the investment.

That is why I have put this quick guide together, showing you how to make an air purifier that will not only keep your air clean, but is also incredibly cheap to make.

So if you are able to spare less than £30 for parts, take a look at this guide and get building.

How to Make an Air Purifier

What You Will Need

  • PVC tubing (one foot, 3-inch diameter)
  • 12v computer fan
  • AC/DC adaptor
  • Filter for a room air conditioner
  • Toggle switch
  • Hose clamp for the tubing
  • Drill
  • Soldering iron
  • Hot glue gun

The Step by Step for Making Your Own DIY Air Purifier

Step One: Preparing the Tube

Take the PVC tubing and drill two small holes in it for the wires of the adaptor (put the wires through these holes).

It is important that you make sure the holes are placed close enough to the top that you have room to install the fan. Once you have done this, make a larger hole between the two small ones. This is where the toggle switch will go.

Step Two: Starting the Assembly

Take the negative wires, twist them together, and then solder them so that they stay together. Now take the positive wires. Twist and solder each of these to the prongs of the toggle switch. Please note that the positive wire for the adaptor may have a white stripe on it.

The negative wires tend to be plain. However, if you are ever in doubt then make sure you call a professional. Poor wiring can be a fire hazard.

Step Three: Continuing the Assembly

Now, push the toggle switch through the large hole, and screw the anchor that it comes with on tight. Then, take the hot glue gun and make sure it is adequately heated so that the stick is melted and ready to apply.

Glue the holes that the wires go into, as well as around the toggle switch. This will form a tight air seal.

Following this, you should allow it a few minutes to cool down. Once it is cool, you can take the fan and place it on top, ensuring that it is centered with the air flow going away from the pipe.

Once this is done, use the glue gun to stick the corners down. Then, form a tight seal around the edges of the fan and pipe.

Step Four: Attaching the Filter

When you get the filter and begin to unfold it, it will reveal itself as a rather large sheet. Feel free to cut this down to size, ensuring that it will not only cover the opening of the tubing, but also go a little over the sides.

It is suggested that you make it around four layers thick. Once this is done, place it on the top of the pipe and use the hose clamp to secure it. Tighten it as much as possible, and then cut off any excess filter.

Step Five: Plugging it in

Now, your filter is complete and waiting for you to use it. Simply plug it into the mains, and it will start working immediately. It actually runs really quietly, which is great if you don’t want to be disturbed while working or sleeping.

They are practically indestructible, which is also a great feature. Once the colour of the filter starts to turn grey, it is recommended that you remove and replace it.

This should be around once every month, depending on the impurity of your air. Even if the colour doesn’t change a great deal, once a month is a healthy change time.

To Conclude

Making your own diy air purifiers can be a lot of fun, but also a much more cost effective way of doing things. Keeping your air clean and breathable is important, and this solution should cost you less than £30 for most of the materials.

While it pays to be a little handy if you plan on making your own diy air purifiers, this guide can be followed by anyone – whether they are beginners or experts in the field of DIY.

Just remember to take your time, and follow each step to the letter. Also, never be afraid to call for professional help if you get a little confused with the wiring.
