What does a Garden Gnome do when she is not gardening, in the kitchen or doing genealogy? Well the answer might just surprise you so read the entries to find out more. This blog focuses on everything we do to make our house a home. There will be a strong emphasis on home energy efficiency and do-it-yourself (DIY) projects. At the same time there will also be crafts, knitting and crocheting projects along with any other little tips we do to create that down to earth, I want to be here home. Please enjoy your visit :)

Duststop Air Filter (Furnace Filter)

Our Honeywell UtilityPR)™ programmable thermostat installed in May of 2010 has a safety feature that will cut cause the display panel to turn off if air flow to the furnace is restricted in any manner.  This serves as a warning that the furnace needs to be checked for anything that may be restricting the air flow.  Ultimately by keeping the air flow at the proper level it saves money.  The Friday before leaving for our vacation home the thermostat blacked out.  I quickly realized that the burner wasn't being lit so called our repairman.  The problem ended up being the drain was clogged and gunked up contacts so it was a relatively quick and inexpensive repair.  A couple of days ago the thermostat cut out twice but we could find no immediate problem.  When the thermostat cut out again the following day we did a bit more troubleshooting.  The most obvious problem we could find was the furnace filter needed replacing.

Duststop air filter
Furnaces us filters to help keep the indoor air clean as well as prevent dust build-up in the furnace that would result in air restriction causing the furnace to run inefficiently.  Furnace filters should be changed every 30 to 90 days.  My husband bought a 2 pack of Dustsop air filters (made in Canada).  These are premium MERV 8 furnace filters that help remove dust, pollen, mould spores, bacteria, pet dander and other household fibres from the air.  MERV is the Minimum Efficiency Reporting Value.  This is an industry standard used to evaluate the filter's ability to capture various sized airborne particles.  The MERV scale ranges from 1 to 16.  Under test conditions it measures the ability of the filter to remove particles from .30 to 10 microns in size.  A higher MERV rating means the filter will be more effective at capturing smaller particles from the indoor air.

Changing the air filter seems to have corrected the problem somewhat.  It was apparent the filter needed replacing so changing it out was a wise decision.  However, the thermostat cut out as I was writing this post so we still need to do a bit more troubleshooting.  So that will be this afternoon's DIY project.
