About Filtrete 20x25x5, AC Furnace Air Filter
84% praised for improving indoor air quality
I have experienced an improvement in air quality after using these filters. With three dogs, the filters capture dust and other pollutants.
After using the new furnace/AC with these filters instead of the old-style one-inch-thick filters, I noticed fresher air with less dust in my home.
After changing to this filter from the standard filter that the builder installed, the air feels lighter and cooler, even a bit easier to breathe.
76% liked its compatibility, but 24% had issues with compatibility
A MERV 16 filter is designated for 'general surgery' by the American Society of Heating, Refrigerating and Air-Conditioning Engineers.
The filter is of great quality but unfortunately not compatible with my Lennox air handler due to its thickness.
80% found it easy to install and replace, but 20% had difficulties
I have to massage the filter material back into shape before installation as all four of the filters I used had pleats bent or crushed, reducing the effective filter area.
Installing the filter is difficult when it is all crumpled up.
74% liked the long-lasting filter, while 26% thought it needed frequent replacements
I will probably replace the filter every 4 months as the original filter lasted for that long before it was nearly plugged up with dust.
I change the filter every 2 months despite the manufacturer's suggestion to run it for 6 to 12 months.
The filter's lifespan is at most a year and depends on factors like climate, pets, cooking, and number of people.
The filter will not catch any dust, but it will last forever.
77% appreciated its high filtration efficiency, while 23% thought it was mediocre
The repair guy explained that the filter causes too much airflow restriction, which makes the furnace shut down due to overheating of the temp sensor.
If the filter is used for a long time with lots of people, cooking, pets and dust, it could harm the HVAC or make it less efficient.
85% appreciated the quieter operation, but 15% didn't notice a difference
The filter keeps the evap coils clean by filtering out a lot of dirt from the air in our house.
I did not mention anything about noise reduction.
On the low setting, a multiple stage system will not push enough air and the airflow will be impacted slightly.
