We are going to get a new furnace and air conditioner installed this fall and are having a diffiuclt time deciding what to do for air cleaner/filter. We currently have an electronic air cleaner that is 19 years old and the heating people say can be hooked up to the new furnace. But they tell me that these electronic filters aren't considered to be so great anymore and are advising some system that uses a 4 inch disposable filter that only needs changed once a year. The cost of the system is around $350.
I have allergies to everything. My husband smokes. So what is the best type of air cleaning system today????
