Jimbo: Nordic Pure is as good as it gets when it comes to filtration. I attached these to box fans to use as air filters and am very pleased with the filters's performance so far!

Michael S: Very good filters delivered in a heavy cardboard box to prevent damage to the filters. After learning my lesson in how nominal measurements differ from actual dimensions, I ordered these filters which are 1/8” smaller than the Filtrete filters they replaced. Perfect fit and sturdy construction.

allan pochop: Ordered the 20x24 size filters....the unit is not a pressing fit therefore. when the furnace comes on, an the fan turn ons one hears a noticaeble loud click as if a door closed. That click is the filter being sucked up off the vent door to the frame. Going to tape filter up to hold it against frame.

Arnell: This is a great product. It works as advertised. This is the second set I purchased. I can't do a scientific study that confirms the level of filtration, but it seems to do the trick. We have multiple animals in my household and constantly vacuum, which creates a lot of fine dust particles/dust throughout the house. These are primarily the allergens I'm trying to avoid getting through our HVAC system. This does the trick. Generally speaking this product is built well and arguably better than the high end branded ones at big-box stores and a cheaper price for the amount of filtration it has. I would recommend.

That being said, you need to be mindful of the MERV rating and your home system. The higher is not necessarily better. The higher the filtration, the harder it will be on your blower motor. It may potentially over stress your system if the filtration is too much. I've have read some HVAC tech advises the least amount to avoid this issue to ensure longevity to your system. The product I purchased was rated at 13, which is on the high end of filtration for most homes. Because of this, I replace these more often than recommended. I believe the recommendation is 90 days,...

Rose from The NorthRose from The North: No MERV rating indicated on box or filters, unlike on seller's sales pix.

I resent having to take important information on faith when we purchasers are paying more fore a higher MERV rating.

Amazon Customer: It fits! It works!
Crisscross reinforcement on package will hopefully prevent distortion that my old brand suffered from.
What more is there to say?
