GeneralAire G99 Air Filter Gauge
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

Comments about GeneralAire G99 Air Filter Gauge:
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.
Pros
- Easy To Install
Cons
Best Uses
- Central Heating
Comments about GeneralAire G99 Air Filter Gauge:
Filter and fan near floor so bought some tubing and installed at eyeball height. Sticks slightly so needs a nudge for accurate read.
Bottom Line Yes, I would recommend this to a friend

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.

Comments about GeneralAire G99 Air Filter Gauge:
As I saw in other reviews of this product, you don't want to use the recommended drill bit size. While it won't have an adverse effect, it is mostly for peace of mind and ease of sealing the unit. I took a little extra time and removed the double stick tape that came on the gauge. Then I used silicone sealant to install the gauge. I used enough so the hole was completely sealed where the gauge entered the furnace and secure the back of the gauge to the mounting surface. I installed mine on the fan housing door as it was the most visible area and the door had excellent weatherstripping so there would be no leaks. Set up was no issue either. Just be patient and turn the screw in small increments and make sure your blower is running on the highest setting. If the unit works as well as the set up went, I will be extremely happy with it and save money by replacing the air filter only when necessary.

Comments about GeneralAire G99 Air Filter Gauge:
Having pets & allergys its great to have a way to know when the filter is loosing effectiveness. My furnace is in the basement and not obstructed on the sides. Mounting the gauge on the side of the furnace was easy and easy to see by bending down. Would recommend the remote hose option would be better to put the gauge in a better visual area, specially if the furnace is enclosed. I even bought one for my girl friends house.

Comments about GeneralAire G99 Air Filter Gauge:
Now I can change the furnace filter when it is needed based on usage instead of what the calendar says.
