Description of Nordic Pure 10X20X1 Pleated Furnace Filtration
Actual Size of Filter: 9-1/2 x 19-1/2 x 3/4. Outperforms comparable fiberglass, washable, and poly disposable filters. Hypoallergenic and antimicrobial pleated electrostatic filter material. Made in the USA.
These are excellent quality filters, made in the USA and overall the filter is more solidly built than other brands of filters in major hardware stores. I will only buy Nordic Pure in the future based on my positive experience.
Buy! Don't waste your money on cheaper ones that don't work, or more expensive ones that don't work better or can overload your system. Worth the money if you have allergies etc. Make sure you breathe clean air in your home! Especially with closed doors and windows and air recirculation mode!
These filters work well. True, I don't have any air quality devices here, but I have no complaints about performance. The only thing I didn't like about them was the unnecessarily large box they came in. She was almost cartoonish.
