air filter on box fan

One of the best things you can do to breathe clean, fresh air at home is to attach an air filter to your box fan! And this easy switch can do a lot to improve the air and keep you healthy. A good air filter can take out dust, pollen and other nasty particles that are likely floating around. Here are some simple steps to boost your box fan and make it more effective for indoor air quality.

You’ll need to collect a few things first. All you need is a box fan and an air filter that fits in your fan. Air filters vary in materials and sizes, so selecting the correct one is crucial. To prevent this, choose an air filter that is able to catch small items such as pollen, mold and pet hair for optimal results. These tiny particles can trigger sneezes or cause congestion.

Add an Air Filter to Your Box Fan

Most air filters have a MERV rating, which indicates their efficiency in trapping particles of different sizes. A higher MERV rating means the filter does a better job of trapping small particles, but it can also make it more difficult for air to flow through the filter. It is also critical to select a filter that clogs well, so less airflow is directed while your fan can still blow somewhat orientated in it.

After obtaining the correct air filter, it’s time to mount it on your box fan. In the above picture, you are going to put this filter on the intake side, ensuring the white sides face out of your furnace (the pleats should be facing out) [Note: Some filters include sticky strips or clips to hold them in place. These often come with your filter — if yours does not, use tape or a rubber band to keep it secure. When you switch on the fan, air will be pulled through the filter, which captures the harmful particles, preventing them from blowing back into the atmosphere.
