By Pei-Ji Chen
Below information is from one website I found for MERV rating. The one I have is 12. This is only 8. That is why so cheap, only 60% of the price."MERV ratings are used to rate the ability of an air conditioning filter to remove dust from the air as it passes through the filter. MERV is a standard used to measure the overall efficiency of a filter. Higher MERV ratings mean fewer dust particles and other airborne contaminants pass through the filter.MERV ratings are determined by adding particles of varying sizes (1-12) into a controlled testing environment. The particles are added upstream of the test filter and a laser particle counter samples the air before it enters the filter and after it leaves the filter. The two particle counts are compared to calculate the Particle Size Efficiency of the tested filter. Once this is determined, a MERV Parameters chart is used to determine the MERV rating.MERV ratings range from 1 - 16 and measurements are in microns. Some of the common particles related to MERV ratings are pet dander, insecticide dust, smog, dust, viruses, wood, tobacco smoke, spores, bacteria and pollen.Some of the most common filters found in residential use only have a merv rating of 1 to 4. These are typically disposable panel type filters and do not do a good job of filtering the air because they will not stop particles smaller than 10 microns.Merv 5 to 8 rated filters are a better choice and are more commonly found in commercial applications. These filters will collect particles as small as 3 microns and are a good choice for home owners also.Filters with a merv rating of 9 to 12 are used in commercial and industrial applications and will stop particles in the 1 to 3 micron range. These filters are a great choice for home owners who want the best dust control possible. When using filters with Merv 9 ratings and above it is important to clean or replace them when recommended by the manufacturer because they will have a negative effect on air flow when they become dirty. This can lead to performance problems and decreased operating efficiency.The most efficient filters have merv ratings of 13 to 16 and will stop particles as small as .3 microns. These filters are used in hospitals and other super clean environments."

By GS on Amazon
The filter may be great, but I may never know. The dimensions given (16x25x4) are smaller than the actual dimensions of the item (x4.25) and won't fit in the furnace. Better spec information would have helped.

By Scott R. Dilworth
I have a geothermal heating system and it uses a 16x25x4 filter. I have been using ones purchased at Lowes which run in the $30 range. I purchased this Honeywell filter as a cheaper alternative. However, it is clearly not made well even though it is a name brand. For example, there aren't many ridges in the filter (to increase surface area) and the ridges aren't evenly spaced thus they bunch up in a couple areas and wide spacing in others. I can probably try and straighten these out but I'm going back to my regular filters after this. I'm rather surprised at the condition.
