Can a DIY Carbon Filter Remove VOCs Like the Expensive Brands?

Free email course: 5 mistakes I made that worsened my home's air quality, and what to do instead. Sign up here: https://renegadeairquality.com/ Can a simple DIY carbon air purifier remove VOCs as well as the more expensive consumer units? In this video, I build a DIY activated carbon setup designed specifically for VOCs (odors) and compare it to three well-known consumer air purifiers: Austin Air, AllerAir, and Airpura. I walk through the build, explain the reasoning behind using separate units for particles and gases, and share performance comparisons. Many consumer air purifiers combine HEPA filters and thick carbon blocks, which can restrict airflow and increase noise. This video explores whether a simple, inexpensive DIY carbon filter can offer a more balanced solution for people dealing with persistent indoor odors from off-gassing, smoke, pesticide drift, or factory emissions. This is not a lab-grade VOC test, but I hope it helps spark a more grounded conversation around how we clean our air. 0:00 - Intro 0:44 - Why didn't I just buy a consumer unit? 5:30 - My solutions to the issues with consumer units 6:42 - How I chose the parts/materials 8:37 - HOW TO BUILD IT 11:15 - THE TESTS (how DIY compares to consumer units) 15:18 - Are the DIY units BETTER than the consumer? 16:49 - Summary PRODUCTS MENTIONED: Smaller, cheaper DIY setup: -6x16 carbon filter: https://amzn.to/4lWReAK -IF THE FILTER ABOVE IS OUT OF STOCK: https://amzn.to/3Yvk016 -Filter box with MERV filter included: https://amzn.to/4ldqkUM -Fan: https://amzn.to/4eqTexY -Buy one clamp: https://amzn.to/4ern3yy Larger, more powerful/expensive DIY setup: -6x24 carbon filter: https://amzn.to/4mdMPsK -IF THE FILTER ABOVE IS OUT OF STOCK: https://amzn.to/452DcqF -Filter box with MERV filter included: https://amzn.to/4ldqkUM -Fan: https://amzn.to/3I6xOdD -Buy two clamps: https://amzn.to/4ern3yy Replacement filters: -MERV-13 for catching carbon dust, $23 each (replace every 6 months): https://amzn.to/3G5B8Fn -Carbon filter above (replace every ~2 years) Above are affiliate links.
