How to Make a Homemade Air Purifier

There are several different methods for making a homemade air purifier. Many articles and how-to videos are out there to show you the process from start to finish. You’ll want to familiarize yourself with how air filtration systems work and the environmental engineering that goes into their creation. Building an energy-efficient, properly working unit can prove difficult. Invest in high-quality materials to ensure a successful build.

Materials Required for DIY Purifier Systems

It’s not often that daily life will drive you to spend an afternoon figuring out the cubic feet of your home to determine airflow rates. That is on the agenda for DIY air purifier creation, however. You’ll need a full set of tools, a 20-inch box fan, and high-grade filters at the very least. The high-grade filters are one of the most important parts, so invest your money correctly.

An air purifier is an indoor air cleaning device that helps rid your home of unwanted indoor air pollutants. This includes gaseous pollutants like ozone as well. Even low amounts of ozone can cause less than ideal conditions for your health. It can even lead to respiratory disease. Different purifiers come in different sizes. They all cover a certain amount of square feet, so be sure to check before buying.

Why Buy Indoor Air Cleaning Devices?

Whether you have a whole-house system or invest in portable air purifiers, the benefits are incredible.

What to Consider Before Building

You’ll always want to look at a few things before purchasing one of these units:

  • The Clean Air Delivery Rate (CADR) of the purifier you’re purchasing
  • Total square feet of your house to find the right-sized model
  • Type of purifier that you’re interested in buying


Some DIY projects can be substantial fire hazards, especially if there is any sort of electricity or writing involved in the process.

  • Make sure your purifiers can handle the square feet of your house
  • Keep up on filter replacement everywhere, including vacuum cleaners
  • Consider having a whole-house system for purification installed

What is activated carbon good at?

Activated carbon is fantastic for cleaning up foul odors and particulate matter in the air, as well as a few other functions. A charcoal filter uses activated carbon.

STAT: Research shows HEPA filters to be standardized at a minimum 99.97% efficiency rating when filtering particles 0.3 micrometers (μm or larger in diameter. (source)
