Hepa or Furnace Filter for Heating Cooling Vents Q&A
From: Elizabeth L
Do you have or know somewhere that carries a (thin) hepa filter to cover a heating vent?
We do not recommend covering a heating vent with a hepa filter because of the resistance a hepa filter presents to air movement. Use of this filter would stifle the circulation of air through your heating vent so it is not recommended.
The best thing you can do is to install a high-quality furnace filter in your whole house central heating system. These furnace filters can eliminate 50% of all dust and can also be anywhere from 70 to 90 percent efficient at removing the smaller particulates as small as 1 to 1.5 microns.
Keep in mind, the particles smaller than this down to 0.3 of a micron would still require a hepa filter, but using it in your furnace would create too much back pressure on your heating system and would reduce the overall air flow. We have furnace filters ranging in price from $79.95 to $364.95. These are permanent filters that require periodic cleaning every 2 to 4 months. They last a lifetime and do not have to be replaced.
