:110 Upgrade Furnace Filters

Welcome to today’s 1:5:10:365 Tip for becoming a better steward for our home and planet.

1:5:10:110  EcoTip: Pleated filters are available that do a much better job than standard HVAC filters. Hot weather is coming so it is time to start thinking about making sure your air conditioning system can run as efficiently as possible.

When you change your filter – upgrade to a higher efficiency pleated filter. They fit in the same slot as a standard fibrous furnace filter but are much more effective in removing dust and small particles like mold spores. 


 Additional Information

Suggested Review – none

The Filtrete pleated filter by 3M has a MERV 11 rating which means it will do a pretty good job of removing mold spores, pollens and other small particles and it fits in a standard system slot.

Lawrence Berkeley research laboratory has excellent additional information of furnace system retrofits and includes information on filters at: http://ducts.lbl.gov/HVACRetrofitguide.html

  2. Make sure you get a electrostatic pleated furnace filter. It will caputure more dirt then a standard pleated filter. The electrostatic uses static electricity to pull dirt particles onto the filter.
