Your house can collect dust and many other matters, which is why having an air purifier is necessary. However, not everyone has the budget to buy one because unfortunately, they aren’t cheap.

If you don’t have extra money to allocate on an air purifier, you can still have one with this DIY air purifier trick. You will need the following:

  • Floor fan
  • One sheet of air conditioning filter (large)
  • Scissors
  • String
  • Pen or marker
  • Tape

If you can’t find an AC filter, a good alternative is a fixer fill, which you can buy at shops that sell fabrics. Another good alternative is an old sweater. Make sure it is not too thick and will allow the air to pass through.

With the materials ready, here are the steps that you need to follow for a homemade air purifier:

1. Take a piece of string, cut it, and tie it around your marker for easy measuring.

2. With the marker and string tied together, measure the back of your floor fan.

3. After measuring the circumference of your floor fan’s back, draw it on the filter.

4. Cut the filter based on the measurement you drew. You will use the filter to cover the back of the fan so it should have a bit of an allowance when you cut.

5. After cutting, use the tape to put the filter in place at the fan’s back. Make sure you apply the tape carefully around this area for this DIY air purifier to work effectively.
