How to Repurpose Your Old Bread Machine Into a DIY Air Purifier

Having an air purifier can make a big difference in improving your indoor air quality, which is important for health and wellbeing. But buying an air purifier can be expensive. Luckily, with just a few easy steps, you can repurpose an old bread machine into a DIY air purifier for a fraction of the cost of buying one.

Why Repurpose a Bread Machine Into an Air Purifier?

There are a few key reasons why repurposing a bread machine into an air purifier is a great idea:

  • Cost savings – Buying a new air purifier can cost $100 or more. By repurposing a bread machine you already have, you save a lot of money. The materials needed for the DIY purifier are very inexpensive.

  • Customization – By making your own air purifier, you can customize it exactly how you want. You can choose the size of filter, type of filter media, fan speed, and more.

  • Fun project – Repurposing something old into something new is always a fun DIY project. It’s satisfying to give an old appliance new life.

  • Effective purification – With the right materials, a DIY purifier made from a bread machine can clean the air just as effectively as a store-bought model.

How a Bread Machine Works as an Air Purifier

Bread machines are well suited for repurposing as air purifiers because they already have a built-in fan and holes for air circulation. Here’s how a bread machine air purifier works:

  • The fan inside the bread machine pulls air in through the vents in the side of the machine.

  • The air is then pulled through a filter to trap particles like dust, dander, and pollen.

  • Clean air is pushed back out the top vents of the machine and circulated throughout the room.

  • The constant air flow through the filter helps remove contaminants and improve air quality.

Choosing the Right Bread Machine

When selecting an old bread machine to repurpose as an air purifier, there are a few things to look for:

  • A strong fan – You want a robust fan that will be able to push enough air through the filter media. Bread makers with multiple fan speeds are ideal.

  • Vent holes on the sides and top – The machine needs vents so air can enter and exit. Vents on multiple sides improves air circulation.

  • A large interior chamber – More interior space allows you to install a bigger filter, meaning better air purification.

  • A detachable lid – You’ll need to remove the lid to insert the filter material. Machines with removable lids are easiest to work with.

Look for a bread machine that has these key features to make the best DIY air purifier.

Choosing Filter Media

The filter media is what actually captures dust, allergens, and other particles as air passes through. There are a few common choices:

  • Furnace filters – Pleated furnace filters trap particles very effectively. Look for MERV ratings of 8+ for best results.

  • Activated carbon – Carbon absorbs gases, odors, and fumes. Pair it with a particle filter.

  • HEPA media – HEPA (high-efficiency particulate air) media captures ultra-fine particles, but can restrict airflow.

  • Polyester or cotton – Pillow stuffing or fabric scraps layered together work surprisingly well to trap larger particles.

I recommend using furnace filters or a combination of materials like carbon and cotton for the best DIY bread machine filter.

Assembly Instructions

Follow these steps to assemble your DIY bread machine air purifier:

Supplies needed:

  • Bread machine
  • Filter media (furnace filter, activated carbon, etc.)
  • Scissors
  • Tape


  1. Remove the bread pan from the machine, if still inside. You won’t need this.

  2. Take measurements of the interior chamber. Cut your filter media approximately 1-2 inches smaller than the chamber on all sides. You want a snug but not too tight fit.

  3. Roll or fold the filter media to fit it into the bread machine chamber.

  4. Place the filter inside the chamber and remeasure to confirm a good fit. Trim the filter if needed.

  5. Tape down the edges of the filter media so it stays securely in place.

  6. Replace the lid on the bread machine. Make sure it is on securely.

  7. Plug in and turn on the machine. Set the fan to the highest speed for maximum air flow.

  8. Place the purifier in the room you want purified! Keep it running whenever the room is occupied for clean, filtered air.

And that’s it! With these simple steps you can easily give an old bread maker new life as an air purifier. Enjoy cleaner indoor air on a budget.

Maintenance Tips

To keep your DIY air purifier running optimally:

  • Change the filter every 3-6 months. More often if it appears dirty.

  • Use a vacuum brush to remove dust from the vents as needed.

  • Wipe down the exterior periodically with a damp cloth to keep it looking clean.

  • Check for obstructions blocking air flow like curtains or furniture. Keep purifier in open area.

  • Monitor the fan noise. Have it serviced if the fan becomes excessively loud or rattly.

With basic maintenance like changing the filters, your homemade bread machine air purifier will provide years of effective air cleaning.


Turning an old bread machine into a DIY air purifier is an easy, economical way to improve the air quality in your home. The right bread maker with a good fan and air vents can filter out allergens, dust, odors, and more when outfitted with the proper filter material.

With just a few basic supplies and these simple instructions, you can build your own air purifying unit for a fraction of the cost of buying one. Plus, you get to reuse and repurpose an old appliance in an eco-friendly way. Just be sure to change the filters regularly to keep your homemade purifier working at peak efficiency. Enjoy the benefits of fresher indoor air!
