1. A box fan (any size will work, but a 20-inch fan is recommended)
2. A high-quality air filter (MERV 13 or higher, or a HEPA filter)
3. Some duct tape or bungee cords

Step 1: Choose the right air filter

The first thing you'll need to do is select an appropriate air filter. I recommend using a MERV 13 or higher filter, as these are designed to capture smaller particles like pollen, mold spores, and even some bacteria. Alternatively, you can use a HEPA filter, which is even more effective at capturing tiny particles. Just make sure the filter you choose is the same size as your box fan.

Step 2: Attach the air filter to the box fan

Next, you'll want to attach the air filter to the back of the box fan. This is the side where the air is drawn in. Make sure the filter is facing the right way, with the airflow arrow pointing towards the fan. You can use duct tape to secure the filter to the fan, or if you prefer, bungee cords can also work well. Just make sure the filter is firmly attached and there are no gaps for air to bypass the filter.

Step 3: Turn on the fan and let it work its magic

Now that your filter is securely attached to the fan, all you need to do is turn it on! As the fan operates, it will draw air through the filter, trapping particles and improving the air quality in your home. Make sure to run the fan on a lower setting to avoid putting too much strain on the motor.

Step 4: Replace the filter as needed

Over time, the filter will become dirty and less effective at capturing particles. It's important to replace the filter regularly to maintain optimal air purification. The frequency of replacement will depend on the air quality in your home and the specific filter you're using, but a good rule of thumb is to replace the filter every three months or when it becomes visibly dirty.

And there you have it! With just a few simple materials and steps, you can create your own DIY air purifier using a box fan. While this solution may not be as effective as a dedicated air purifier, it's a budget-friendly way to improve the air quality in your home.
