Homemade Air Purifier: Reduces 90% of allergen particles

Many people with sinus problems have underlying allergies to dust, pollen, mold or animal dander. All of these can build up in the air inside homes.

One of the best ways to get rid of allergy symptoms is to avoid allergens in the first place, says Jeffery E. Terrell, M.D., director of the University of Michigan Health System’s Michigan Sinus Center. 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.

Start with a 20-inch by 20-inch box fan, which often retails for about $12. To the front of it, tape a 20-inch by 20-inch by 1-inch furnace filter.
