My son has allergies to dust, mold, cats, etc. His allergist advised us to use Filtrete filters. They really do help! He does't get runny eyes, cough, or sneezing since I replaced my other brand. He sleeps much better and my furniture is dust free longer. I was dusting my furniture daily with a special cloth, but now I only dust twice a week. I like that this filter captures pollen, pet dander, candle or kitchen smoke, bacteria and  viruses. My home has very clean air now and we all sleep better.
