About Nordic Pure 20x20x4 MERV 12 Pleated AC Furnace Air Filters 2 Pack
Overall Feedback:
82% positive
80% liked its compatibility, but 20% had issues with compatibility
It affected the air flow a bit compared to my previous filters, but I adjusted the fan speed to compensate for it.
Most poor reviews are due to the filter not fitting, but the actual filter size is provided, so it's unfair.
83% found it easy to install and replace, but 17% had difficulties
The filter can be taped or tied to the back of the fan if needed, as it is held in place by the suction of the fan.
I am concerned about air leakage around the outside of the box, which makes it useless.
80% liked the long-lasting filter, while 20% thought it needed frequent replacements
I noticed that the first TechPure filter that came with my new unit was quite dirty just after 4 months, which is much sooner than the expected lifespan of 1 year. I can already feel the difference in airflow with the new filter installed.
I doubt that the filter can perform as well as the more expensive one I replaced, which may lead to a shorter lifespan of the filter.
80% appreciated its high filtration efficiency
I switched to the merv 15 version of the filter in December and it helped with my allergies. The filtration difference is significant and there is much less dust.
81% appreciated the quieter operation, but 19% didn't notice a difference
I did not mention anything about the noise reduction of the filter.

Nordic pure plus carbon works well in my home HVAC system and lasts about a month in heavy use, while Nordic pure carbon only lasts a couple of weeks before air flow is blocked.

I removed the filter and noticed a significant improvement in air flow and a decrease in noise, suggesting that the filter was causing turbulence in the blower.
