Very cool. Anyone seen a mod that adds activated carbon? A lot of DIY filters are very cost-effective, but the lack of activated carbon is a big downside compared to commercial solutions.
There's really only two air cleaning technologies that are worthwhile right now:
- HEPA filters (remove PM 2.5 particulate and above).
- Activated carbon (neutralizes harmful gases).
The only other thing that may be worthwhile is a pre-filter, but that is mostly a cost saving measure rather than actually improving air filtration.
Unfortunately commercial filters are full of gimmicks that don't work or may even be harmful due to Ozone generation (e.g. Ionizers, UV lights, et al.).
- papercrane 4y agoYou could buy an activated charcoal filter built to attach to the same inline fan booster from most garden stores that carry indoor growing equipment. They're popular with people growing cannabis indoors to remove the smell from their grow area. Something like this: https://www.amazon.com/dp/B07GSKFBL8/ https://www.amazon.com/dp/B07GSKFBL8/
