Description

Filter manufacturers recommend replacing the filter regularly. As it processes air, the filter traps pollutants and allergens. A full filter causes the HVAC system to work harder, increases energy costs and reduces indoor air quality. An air filter gauge monitors the level of contaminants in the filter. Install it between the blower and the filter. When the filter is full, the vacuum in this location increases and raises the vane on the gauge. A built-in screen traps dust and keeps the gauge clean. Use an extension kit to mount the gauge up to 10 feet away from the location you wish to monitor. Easily replace the gauge when needed.

  • dial is easy to read
  • simple to calibrate
  • easy to install
  • build-in screen removes dust from the air samples and keeps the gauge clean
  • mount up to 10 feet away from monitoring location

    Rigged up my own extension kit to put the gauge at eye level. Easy calibration. Now I don't have to wonder about when to change the filter.

          Dealer claims he knows how often I should change the filter.
          I think a measurement is a much more accurate assessment.
          Drill a small hole, easy installation.
          Newly installed, I expect it should be problem free for years - we'll see.

              Comments about GeneralAire G99 Air Filter Gauge:

              The gauge was easy to install and will let me know when the filter needs to be changed without guessing. I use high quality filters and changing them unnecessarily is expensive, but not changing it when it is dirty is hard on the furnace and bad for air quality. Now I will know for sure. I haven't had it long enough to need a filter change at this point.

                Comments about GeneralAire G99 Air Filter Gauge:

                I installed this unit using a piece of tubing, which allowed me to mount the gauge on the outside of the duct and sense the vacuum between the filter and fan. I used window caulking to seal the tubing at both ends.
                My only problem was the gauge read the same reading with the new filter and the old. The old 5 inch thick filter had been in the system for 7 months and I expected a significant difference.
                It was easy to adjust to get a gauge reading. Either my old filter was clean after all those months or there is something else wrong with my system.

                  Filter and fan near floor so bought some tubing and installed at eyeball height. Sticks slightly so needs a nudge for accurate read.

                  Saves Money! You'll know exactly when to change the filter. Don't throw away a good filter early, and don't overwork your AC Compressor or Furnace Fan.
