About Honeywell FC100A1037 Ultra Efficiency Air Cleaning Filter
78% praised for improving indoor air quality, but 22% didn't notice a difference
The new filter has poor construction where the paper element is not attached to the cardboard frame and allows unfiltered air to pass by.
I am unsure about the air quality improvement of the furnace-filter as it was damaged when I received it. I am disappointed with the seller for sending a damaged product.
92% liked its compatibility, but 8% had issues with compatibility
I was surprised to find that it was difficult to fit the Honeywell filter in the unit, despite the identical listed dimensions of the two filters.
The filter does not fit a generic 25x20x5 whole house filter return cabinet.
The width of the product is 1/2 inch larger than any other 20x25x5 filter I had before.
87% found it easy to install and replace, but 13% had difficulties
I discovered that the Honeywell unit requires removal of an alignment pin on the bottom wall before fitting a new cardboard filter.
The replacement filter arrived damaged with one side banged up and the cardboard strips torn on both sides. But I was able to straighten it out and refold the pleats as best as I could and the service tech felt it was usable.
81% liked the long-lasting filter, while 19% thought it needed frequent replacements
I have used this filter for a while now and it works great. The original filter was full of dust and pollen after only 6 months. Based on my experience, I can say that this is a great filter.
I have replaced the filter after 1 year.
Our filter has 50% less surface area, significantly limiting its lifespan.
80% appreciated its high filtration efficiency, while 20% thought it was mediocre
The filters are shorter than they should be, leaving a gap for air to get around and causing them to sit lopsided. This may affect their filtration efficiency.
The filter I received has 50% fewer pleats than the picture, significantly limiting its life.
95% appreciated the quieter operation, but 5% didn't notice a difference
I prefer the paper filter over the old electrostatic filters because it eliminates the zapping sounds.
The new filter allows unfiltered air to pass by, affecting the noise reduction of the furnace-filter.
