I built the best DIY heat recovery ventilator I’ve seen on YouTube

I built a heat recovery ventilator (HRV) from only sheets of corrugated plastic and adhesive. EDIT: SEE PINNED COMMENT for some corrected efficiency metrics. To summarize, my HRV is actually 60% efficient (which is still decent!), not 85%. Even so, it works great! My HRV is powerful enough to deliver fresh air to most of my house, and it’s designed to use 4” thick MERV-13 filters to help keep harmful particulate (PM 2.5 and 10) out. It greatly reduces VOCs and CO2 as well. My indoor air quality has significantly improved. The cherry on top: it cost me less than $300 in materials to build!

So, I measured the CFM at the supply outlet at various fan speeds. Here’s the data: With an anemometer distance of 6-8 inches from the outlet: -speed 1 of 8: ~100 cfm -speed 3 of 8: ~150 cfm -speed 6 of 8: ~250 cfm -speed 8 of 8: ~330 cfm
