A HEPA-type air-filtration system for ~$25.

I'm just getting over my allergies -- that were causing me troubles for much of the springtime. It was with this in mind that it made me very happy to see a story about building a cheap air purification system.

To avoid indoor allergens, many doctors recommend using an air purifier with a High Efficiency Particulate Air (HEPA) filter. The cost of these machines can run from $75 up to $800 for high-end systems. For those who are looking for a cheaper alternative for high-use rooms such as the bedroom, Terrell offers a do-it-yourself solution at a fraction of the cost. “This is a filtration system that you can put together with items from your local hardware store for $25 to $30 and use in your home to cut indoor allergens by about 90 percent,” says Terrell.
