Here are some more examples of how to make an air purifiers:

Here are the things that you need to make a simple, compact air purifier:

  • CPU Blower – 12 volt
  • Motorcycle air filter
  • 12-Volt Battery
  • DC Wire
  • Glue Gun

To make the air purifier (video), follow the steps below.

  • Use the glue gun to attach the motorcycle air filter on top of the CPU blower (the opening of the fan). Press the two objects against each other firmly.
  • Straighten out the DC wire.
  • Connect the CPU blower’s wire to the DC wire to make it longer.
  • Attach the wire endings to the 12-volt battery’s ports.
  • This homemade air purifier works by sucking in polluted air through the filter and releasing clean air through the CPU’s blower outlet.
  • This model of DIY air purifier is quite weak and is only intended for small rooms or small areas.
  • Since the unit’s wire is directly connected to the battery, it doesn’t have a control system for the on/ off functions.

Here are the things that you need to make a box fan air purifier (video):

  • Box fan – 20 inches
  • HEPA furnace filter or air cleaning filter – size 20×20 inches
  • Duct tape

Assembling your box fan air purifier involves very simple steps:

  • Make sure that the fan is unplugged.
  • Using duct tape, attach the filter at the back of the fan.
  • Plug the fan and turn it on.

  • This box fan air purifier works by sucking polluted air into the fan system and filtering the dirt (and other allergens) from the air. Purified air is then released back into the room.
  • To make sure that your fan air purifier is always working at its best, clean the blades from dust regularly.
  • This air purifier can be operated just as you operate a fan. If your fan has 3 speeds, you can also operate this DIY air purifier using 3 speeds.
  • Note that this type of homemade air purifier is only intended for box fan models as their design allows them to be converted into an air purifier. Other fans are not really designed for this purpose (to run with filters) and are therefore not suitable as materials.
  • For a really effective air purification method, choose filters that have high ratings and efficiency scores. Otherwise, your homemade project will only have a short lifespan.

We all need the best air purifier for large room or whole house because we are living in a highly polluted world – that even our indoor environment is filled with airborne pollutants and contaminants.

Air purifiers are designed to filter dirty (polluted) air so that this can be converted into clean air. The process is really simple as airborne particles are sucked into the device so that clean air can be released back into your indoor environment.

With clean, fresh air in your home (or office), your immediate environment will be odor-free, dust-free, and germ-free as well (depending on the type of air filtering system your unit has).

Of course, there are also disadvantages to making your own air purifier. Consider the points listed below.

  • Because of your limitation as a sole maker of a homemade air purifier, the features and designs of the unit can also be limited in nature.
