For the Spring 2021 class project of the Engineering 535, Development Technology class at Humboldt State University, we were tasked with designing, building and testing an affordable and easily replicable wildfire smoke mitigating air filtration system for low income families or individuals. The Do It Yourself (DIY) air filter was deigned to efficiently filter particulate matter in wildfire smoke and PM 2.5 (particulate matter 2.5) from other indoor pollutants. The ease of use for people with physical disabilities was also considered as seen in the inclusion of swivel caster wheels at the bottom of the air filter. The efficiency and cost effectiveness of the DIY air filter was found to be equivalent to that of a typical off the shelf air filter system.

Note[edit | edit source]
- This air filtration system was designed to be used by people of different physical and economic ability.
- The air filtration system is designed to trap particles down to 0.3 microns including dust, pet dander, pollen, dust mite debris, mold, bacteria, microscopic allergens, virus, and smoke smog.
- The DIY air filtration system is four sided to allow use in different conners and room sizes and shapes such that the filtration process is not compromised by the area where it is being used.
Caution[edit | edit source]
- Remember to change your filters when they get dirty.
- Estimated time of use before changing the filters was not measured.
- For more information on how to safely and effectively use this DIY air filter, please see the user manual below.
User Manual[edit | edit source]
Other safety and user tips[edit | edit source]
- Reduce the strain on your filter by ensuring minimal polluted air entry into the house, especially during wildfire season
- If you have one filtration system, prioritize use for those that need it the most i.e., people with respiratory health problems and children.
- Do NOT kick your filtration system to move it.
- Keep it in dry clean place when not being used.
- It is better to buy the necessary materials required during the low season i.e., out of wildfires season.
