Electronic Air Filters

[kn]

Here's a dumb question. Is it necessary to have an electronic air filter on 24/7? I would think there's no need to run it during the summer months when your furnace is hardly operating.

But I really don't know and haven't been able to find an answer on-line. I do know it's recommended to change the filters approximately once a month.

It is not necessary to have it on 24/7. I do have my fan on 24/7 in the summer for better air circulation. In the winter the fan comes on only when the furnace kicks in.

Is there anybody with allergies in the house?. Different filters available for that. I check my filter once a month but if it is not dirty I don't bother changing it. I work with furnaces and boilers so dirty can be a rather subjective word. Do you use a reusable filter or a throw away?.

Thanks for the reply Svartsengi.

There is a person with allergies and that is why it was originally installed. The filters are reusable but I think I'll keep it off until the furnace is used regularly.
