I do this and it works wonders if you have pets.
Tips:
- run this homemade air purifier when you are vacuuming, as that tends to agitate particulates a lot
- get 2 filters, a cheap low grade and a premium, high-HEPA-rated filter. Stack them together and you can replace the cheap one frequently and the expensive one less frequently.
Swedish tracing paper works well for a pre-filter. It's inexpensive for a long, seemingly inexhaustible roll, and can be washed numerous times.
It also works well by itself if you just want to cheaply filter large particulates. I used to use it in those cheap $40 Hamilton Beach air purifiers. The OEM filters for those cost almost at much as the new unit and wear out [for me] within a couple of weeks. That setup with Swedish tracing paper works well for dust, as a supplement for my HEPA filter purifier.
I am so tired of dust in my studio. There is no ventilation other than the small fan in the bathroom or the big sliding door in the front. So I leave the fan turned on overnight but because of pressure difference, very small particles keep accumulating all over my place. I’m really hoping this changes that.
