Works Very Well, Easy to install and it WORKS!!

The supplied hose allows you to mount the meter up to 10 feet from the furnace, but I didn't need it.

It installs in about five minutes and now I just look at the gauge.

We recently purchased a new furnace, and one of the features of it's new thermostat was an indication of when the filter should be replaced. Sounds like a great idea, until in reading the installation booklet on the thermostat, I discovered it was nothing more than an "electron timer/reminder" that can be set from few as 30 days to more than a year.

This Air Filter gauge takes the guesswork out of when to replace the filter. In my case after 6 months of usage I got the message of replace filter. Apparently the furnace installer choose 6 months as the life expectancy of my filter. The filter still looked pretty good to me however, but I ordered a replacement filter at the same time as ordering this Gauge Kit. I installed the gauge kit, and calibrated it with a fresh filter installed. Then to get a comparison reading I put back the 6 month old filter. The reading increased slightly with the old filter but still well within the good range.

I'm guessing I could have delayed purchase of the $80 replacement filter for another 6 months.

I'd recommend that you recalibrate the gauge each time you install a new filter since even new filters do not always perform the same. Also the air handling blower should be running at it's highest normal speed, when calibrating and/or checking the filter gauge, since this is also when you'll see the highest reading.

We have been having some issues with our furnace. A tech suggested that we not use a high efficiency filter (Filtrete 1250) because this reduced the airflow and caused the furnace to run hot.

I did lots of research about this. It's hard to find specs for filters. So I bought about 5 different types. I set up a crude "device" to compare the airflow from each: taped a half-sheet of notebook paper to a vent in our dining room, then swapped filters and measured the distance of the paper off the floor for each one. I did find measurable differences, but knew this was pretty rough.

So I bought this filter gauge. It confirmed my tests but with much more accuracy. Compared to the filter I finally ended up using (a polyester one sort of like the cheapo fiberglass) a brand new Filtrete registered as "dirty" with the gauge.

One more hint for anyone doing the testing I did: we have an instant-read thermometer we use for cooking. I taped it to a heat duct right next to the furnace to see the difference in the temp with different filters. This was crude too, but it worked (as far as showing the differences between filters, but not the actual heat rise in the furnace).

What a great little gauge! Easy to install and gives immediate and accurate feedback about the condition of the air filter. We just had a new high performance heat pump installed. The HEPA quality filters are over $100 each, with manufacturer's recommendation to change the filter twice a year! With this gauge I am safely able to more than double the service time of the filter without worrying about damaging the equipment. Paid for itself within the first month or two.

I dunno, I like the concept of this device. I use it and trust it to change filters generally. Its just so sensitive I'm not positive what its telling me. You put in a new filter and calibrate it. When the needle goes red you replace the filter. Just touching the gauge makes it jump all around though which makes me question its reading. I double check what its telling me by inspecting the filter. That just sort of defeats its purpose in life

After years of forgetting to clean the filter on my Jet air cleaner this baby makes it simple. It installs in about five minutes and now I just look at the gauge.

The idea is to set it with the calibration screw to the Good mark when the filter is new. Then when it starts plugging up, it works its way to the Red range. That sounded like and excellent concept, and I don't know how anyone could do much better. I didn't have the install problems others had. I thought it went really well, and was quite pleased with the way it looked and worked when I was finished. I believe for most people, the furnace is not a very big duck in their pond, until there is a problem. They replace the filter when they think about it, which may or may not be when it actually needs it. I was thinking this might help.

Reasons it didn't work out.
1. Different medium have different restriction. The furnace even say what to use, and what to expect from the different types, and the restriction build between clean and dirty is different. Thus, I can't know if it is time to change the filter when the needle goes into the red.
2. My furnace is a 90%+ furnace as is common these days. The blower runs at all different CFMs, based on what the controller decides based on its sensors, and whether you are running heat, AC, or just the circulation fan, and the CFM range is huge. My furnace even says it auto-compensates for filter restrictions when it starts to get dirty. However, the device can only be calibrated for one CFM. It might work better on a furnace with a fixed speed blower and standard 1" thick fiberglass filter.
3. Will you actually look at it? I didn't, once the novelty wore off. I looked at it when there seemed to be not much air coming out, and then it was way overdue.

I believe the furnace manufacturer is in the best position to tell you when the filter needs to be changed.
