An air purifier can do wonders for helping reduce allergens such as pollen and dust in your home. However, some of the systems available can be extremely pricey. Understandably, this may discourage you from getting one for you home. Luckily, in this case you can have your cake and eat it too (or in this case have your air and breathe it too)! This do-it-yourself air purifier project will only costs about $30 to put together, and can help you breathe easier and ease your allergy symptoms. Once you construct it, place it in your bedroom to help you get a better night’s sleep.

What you will need:

  • 20 x 20 inch box fan

  • 20 x 20 inch HEPA furnace filter

  • Tape


Putting this air purifier together is extremely simple and quick. The most complex part of this process is making sure you purchase a HEPA furnace filter that has a good level of filtration. The better filter you buy, the better results you will get from your new air purifier. After you have all of your supplies, simply tape the filter to your box fan and you’re ready to go!

The Perfect Place (or Places) in Your Home:

Once your new air purifier is complete, you can place it anywhere in your home. Each one you make will cover one room. This means that you may want to complete this project a couple of times. This is especially true if you have any children with allergies. “...allergies account for the loss of an estimated 2 million school days per year.” Having an air purifier in your children’s rooms can help combat this problem and help them feel better all year round.

This simple do-it-yourself project is the perfect solution to all of the expensive air purifiers that are on the market. Not only with you save a lot of money, but this project is quick and effective. Still craving some more DIY crafts? The fun doesn’t have to stop with this project!
