(More customer reviews)Review of 3M Filtrete - Ultra Allergen
These are outstanding air filters, based on the lack of dust and clean air inside our house; the build quality of these filters; and the fact that they have such a high rating. We've been using these filters for about 10 years in a Trane heat pump system, with no issues.
This filter has a 3M Micro-particle Performance Rating of 1250. "MPR" focuses on a filter's ability to capture the smallest particles between 0.3 and 1 micron. The higher the MPR, the more effective the filter is, and the more expensive. The "basic" Filtrete is the least expensive. These are near the top-end. Their highest filter is MPR rated at 1700, but costs about 1/3 more that this one, and I can't tell the difference; although someone with allergies probably could. See TYPES OF FILTRETEs after this review for more information.
Ours is a two-story house with a basement. There are two returns in the system, high in the wall, one each on the first and second floors. Several years ago, to do an even better job of air cleaning, and to keep 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 of those returns. In other words, all air flows through two Filtretes, which has been no problem for our heat pump's air exchanger. (Since there's no gas or oil "fire", it's not called a furnace). With this setup, the 3 filters need replacement every six months. Before adding the two return filters, we replaced the single air exchanger filter every 2 months, so total filter cost is the same.
One reviewer said: "little did I know the extra drag on the air flow would cause my Lennox Heat Pump to burn up." All filters cause some drag on air flow, but the only way that could become a significant drag is if the filter was very 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 around the filter. Dirty filters reduce the efficiency of heat pumps or furnaces, but claiming a heat pump "burned up" because of a high-efficiency filter's air drag, is a stretch. It's more likely that his contractor gave him that line to switch blame away from the Lennox equipment, which failed for another reason.I checked the Lennox web site, and they don't even mention disposable filters, which isn't surprising. Imagine Lennox Corporation warning customers not to use 3M filters because their equipment can't handle the stress.
We don't have pets or allergies; we use these filters because they result in very clean indoor air.TYPES OF FILTRETEs
