Review of 3M Filtrete - Ultra Allergen
These are outstanding air filters, based on the lack of dust and clean air inside our property the construct top quality of these filters and the truth that they have such a high rating. We've been working with these filters for about ten years in a Trane heat pump system, with no issues.
This filter has a 3M Micro-particle Efficiency Rating of 1250. "MPR" focuses on a filter's ability to capture the smallest particles between .three and 1 micron. The greater the MPR, the a lot more successful the filter is, and the additional high priced. The "simple" Filtrete is the least costly. These are close to the leading-finish. Their highest filter is MPR rated at 1700, but fees about 1/three more that this one particular, and I can not tell the distinction although an individual with allergies most likely could. See Sorts OF FILTRETEs soon after this critique for far more data.
Ours is a two-story home with a basement. There are two returns in the technique, high in the wall, one particular each on the very first and second floors. A variety of years ago, to do an even much better job of air cleaning, and to maintain the inside of our ducts clean, I replaced both return grilles with a grille assembly that has a built-in "furnace" filter holder. We use 3M Filtrete Ultra Allergens in the system's air exchanger and at each and every of those returns. In other words, all air flows by means of two Filtretes, which has been no predicament for our heat pump's air exchanger. (Because there's no gas or oil "fire", it's not referred to as a furnace). With this setup, the 3 filters need replacement every single six months. Before adding the two return filters, we replaced the single air exchanger filter every single 2 months, so total filter price is the identical.
A single reviewer stated: "little did I know the added drag on the air flow would lead to my Lennox Heat Pump to burn up." All filters result in some drag on air flow, but the only way that could turn out to be a considerable drag is if the filter was especially dirty, which would be the fault of the homeowner for not replacing it. In my setup, if a filter is overdue for replacement, it arches in the middle (from the air drag) towards the fan's suction, and the air whistles as it rushes about the filter. Dirty filters reduce the efficiency of heat pumps or furnaces, but claiming a heat pump "burned up" since of a high-efficiency filter's air drag, is a stretch. It really is more most likely that his contractor gave him that line to switch blame away from the Lennox equipment, which failed for a different cause. I checked the Lennox web web site, and they do not even mention disposable filters, which isn't surprising. Envision Lennox Corporation warning shoppers not to use 3M filters for the reason that their gear cannot deal with the stress.
We don't have pets or allergies we use these filters due to the fact they result in especially clean indoor air.
Types OF FILTRETEs
I did some analysis, and found that 3M tends to make three classes of disposable Filtrete 1" filters for heating and cooling systems, with many possibilities inside every "class" 14 numerous Filtrete filters in all.

I discovered this Amazon product page although seeking for data on furnace challenges and this filter.
We've been making use of the red "micro" Filtrete filters for years. This was our first try with the purple "Ultra" filters. I tried 1 in December, and removed it these days (January three, 2010).
It cut our heating capacity by at least 40%!
With the red Filtrete, we have at least 92 degrees of heating capacity: if we set the thermostat at 72, the residence maintains 72, even when the outside "ambient" temperature (the typical of the day's low and high) is -20 degrees F.
Yesterday and right now, we lost the capacity to keep temperature. On a day with an typical temperature of ten degrees F (low of 5, high of 15) the property dropped to 65 degrees. So, rather of getting in a position to heat the residence to at least 90 degrees above the outside temperature, we are down to only 55 degrees.
The FAQ on the 3M website glosses more than this situation.
"Do I have to be concerned about restricted airflow with Filtrete filters?
Filtrete filters are designed to operate in most residential furnaces and air conditioning systems. If a Filtrete filter remains in use longer than three months, it can start to restrict airflow or cause the technique to malfunction. It also could restrict airflow in some greater efficiency/air conditioning systems. In this case, alter the filter a lot more frequently."
Bull! Our furnace is not "high efficiency", it's an older 125000 BTU Singer, with a 160 degree limiter on the heat exchanger. A 3 or 4 week (not month) old purple "Ultra" choked the furnace, but when I place the two month old red "Micro" back in, the temperature came correct back up!
