There is nothing worse than air that is thick with allergens, and the reactions that come with it. You don’t deserve to spend your time suffering with dirty air, and we know that not everyone can afford an air purifier to keep things nice and clean.

To help you out, we have put this instructional guide together on how to make your own air purifier at home, and on a budget. It’s a lot easier than you might think, and it really does work!

Before we start, it is important to know what an air purifier is and how it can benefit you.

What is an Air Purifier?

An air purifier is a device which works to remove contaminants from the air and leaves it cleaner than it was before. The allergens and trapped in the filter, which is replaced on a monthly basis (or more depending on the device).

It is incredibly beneficial for those who have asthma or allergies as the culprits responsible for the reactions are trapped in the filter and unable to return to the air. This makes for a cleaner and more breathable experience. It can also help to reduce the amount of second-hand tobacco smoke that people in a home are exposed to if there are indoor smokers.

Now that you know a little more about air purifiers and what they do, we can move onto the process of making one for your own use.

What You Will Need

Here is a list of the items that you will need before you can begin the process of constructing your own:

  • A foot of 3 – inch diameter PVC tubing
  • A 3 – inch diameter computer fan (mine was 12V)
  • An AC/DC adapter, with a DC output the same as your fans
  • Filter for a room air conditioner
  • Toggle switch
  • Hose clamp for the 3 – inch pipe
  • Drill and various bits
  • Soldering iron + solder
  • Hot glue gun + sticks

Once you have all of these items together, you can get started with making your own.

Step 1: Preparation

Take the tube and start by drilling two small holes on either side for the wires from the adapter and the fan wires. The holes should be placed close to the top (about an inch) to ensure that the fan can be installed comfortably. Once this is done, make a larger hole between the two small ones for the toggle switch.

Step 2: Soldering

Hold the wires in your hands and take the negative ones and twist them together. Once this is done, solder them. Once you have done that, move onto the positive wires and twist those together before soldering them to the prongs on the toggle switch. Ensure that the wiring is inside the tube.

Step 3: Assembly

Now, take the toggle switch and push it through the large hole before securing the anchor that comes with it by screwing it on. Then take up the hot glue gun and glue the holes that the wires go through and around the toggle switch to form a tight and secure seal. Leave it to cool for a few minutes afterwards.

 

Once everything is cool, place the fan on the top of the pipe with the air flow positioned so that it is going away from the pipe (this ensures clean air is pushed out). Once you are sure it is in the right position, use the hot glue gun to stick the corners down and secure them. Following that, form a tight seal around the fan and pipe with more glue.

Step 4: The Filter

Take the filter and unfold it completely. There are some that are quite large, and so you have the option to cut it down or fold it (depending on your preferences). Some prefer to have a thicker filter as it can catch more, whereas others prefer to replace the filter on a more regular basis.

Once you have decided what you want to do, place the filter on the other end of the pipe and use the hose clamp to secure it. Tighten it as much as you can, and then cut off the excess corners so that you don’t end up catching it on yourself.

Step 5: Completion

Now that it’s done, you can switch it on and let it work its magic. The filter will need to be changed once a month, or when the color starts to darken from the original white and towards a greyish hue.

To Conclude

Hopefully, you have found this little step-by-step guide to creating your own air purifier at home easy to follow and create. It’s a simple and affordable option for many, and it doesn’t require too much in order for you to get started. Everyone deserves to have a home filled with clean and breathable air, and with this, you can too.
