How to make DIY air filter for wildfire smoke

Wildfire smoke is full of small particles that can get into your eyes and lungs causing health problems including chest pain, headaches, or an irregular heartbeat.

Keeping your windows and doors closed and using an indoor high-efficiency HEPA filter can help keep indoor air as clean as possible. High-end filters can be expensive if you don’t already have one in your home, but the good news is you can make one for a fraction of the cost in just a few easy steps.

All you need to do is buy what’s called a MERV 13 or FPR 10 furnace filter and tape it to the back of a box fan. The filters sell for about $15. Don’t worry if you don’t have any tape because the suction from the fan should make the filter stick to the back.

Air filters should be used in your bedroom or in the room where you spend most of your time.
