I have several family members who are the unfortunate sufferers of allergies.  I also used to have a dog who had terrible seasonal allergies.  Below are some tips from Natural Home & Garden Magazine on how to fight allergies in your home without breaking the bank.

Pricey:  Central electronic HEPA filter system to reduce airborne dust mites, mold spores and pollen: $600-$1,000
Thrifty:  Portable HEPA air filter in sleeping area: $150-$300

Pricey:  Whole-house water filter: $900
Thrifty:  Shower filter (removes chlorine): $75
               Kitchen sink filter: $150

Pricey:  All-natural wool carpeting (dust mite desistant) or VOC-free cork flooring to cover 2,000 sq. ft.: $10,000 and up
Thrifty:  VOC-free sealant to cover 2,000 sq. ft. of existing wood flooring: $150-$250
