FILTRETE MERV 11 MPR 1000 MICRO ALLERGEN DEFENSE 2-INCH AIR FILTER REVIEW

March 21, 2021

6.6 / 10 Filterstudy Score
PFE1 Efficiency (0.3-1 μm)4.6
PFE2 (1-3 μm)7.6
Permeability / Pressure Drop7.5
Pros
* Higher dust-holding capacity than most 1-inch filters. Requires less frequent maintenance (filter replacements).
Cons
* Less than mediocre performance at filtering 0.3-1µm particles, which are more likely to lead to chronic lung-related conditions.

* OK performance at filtering 1-3µm particles, which are more likely to cause various respiratory problems and other health and productivity issues.

* OK permeability. The lower the permeability score, the more strain the filter would put on your equipment which can dramatically increase the cost of operating your furnace, air conditioner, and heat pump.

* Requires an aftermarket filter housing which could potentially require a professional installation.
