Choice of a furnace filter or an air purifier is more important than the choice of the furnace itself. A good (5 inch wide) furnace air filter has large surface that can catch a lot of dust without restricting the airflow. Bad furnace air filter (1 inch wide) can ruin the best furnace and the air conditioner. With a good furnace filter even entry level furnaces will last and last.

Hepa Air Purifier for Home

In some homes, filter HEPA type was used in the past before 5 inch filters came to the market. As you can see from the picture, the HEPA air filter diverts only a part of the air flow, usually 1/4. Only that part of the air flow goes through the hepa air purifier and gets cleaned.

These days we have 5 inch furnace air filter that does exactly the same job as HEPA furnace filter but for the entire air flow, not just 1/4 of it. Also, it eliminates a restrictive 1 inch filter. All this makes use of HEPA air purifier for home obsolete.

Once again, for anything that HEPA furnace filter is trying to do for a part of air we have a whole house furnace filter that does the same for the entire air flow.
