What can I do to relieve allergies and keep the dust and pollen out of my house? –Bitsy
A good quality air filter on your HVAC heating/cooling system is the first line of defense against dust, dirt, and airborne allergens in your home. Consider a filter with a high microparticle performance rating such as Filtrete filters from 3M. While costing more than fiberglass filters, they do a much better job of cleaning the air and last longer.
