Allergan-reducing products not effective against asthma

Special mattress pads, allergen-reducing fabric sprays, air filters, and so forth ... if you have asthma you may have invested lots of money in products such as these. Dust mites can be a big asthma trigger, and trying to minimize them is a good way to reduce asthma episodes. But a research group has determined that many of the special efforts people take to reduce allergens and dust mites aren't effective enough to make a difference.

Previous studies have reviewed both physical and chemical allergen reducers. The research group reviewed 54 studies. They found that, while many products were ineffective, others did reduce allergens as advertised -- but not enough to ward off an asthma attack.

If you currently own special products such as fancy vacuum cleaners, air filters, and mattress pads, feel free to keep using them. Many do reduce allergens, though they aren't effective enough to make much of a difference. A good habit to get into is washing sheets, blankets, and pillows often using high temperatures. Also, remove soft toys from your child's bed.
