Your search matches the manufacturer’s listed filter identifier.
Before you buy
This lookup identifies the exact Nordic Pure pack, not a confirmed match to your furnace or air conditioner. Check actual dimensions and the rating allowed by your equipment manual before buying. Other 20x20x1 filters, ratings and pack sizes are not interchangeable by name alone.
Why this filter
What’s included
Two identical MERV 8 filters. Use one at a time when your system takes one filter; keep the other for a later change.
Size and fit
The printed size is 20 by 20 by 1 inch. Actual measurements are 19.5 by 19.5 by 0.75 inches. Measure your existing filter and slot; the printed size alone does not confirm a fit.
Filtration rating
Nordic Pure labels these filters MERV 8, an air-particle capture rating. We have not independently verified a test report for this specific filter. A higher rating is not automatically better if it restricts airflow in your system.
How this compares
This is a checked replacement, not a Best Overall or Best Value winner yet. Before choosing a winner, we need other filters we can trust, a fair comparison of how they work and how reliable they are, and current prices including shipping.
Filtration tests and details
These records explain which filter results we have checked and what their limits are. The same certification name does not mean two filters work equally well.
What we have verified about filtration
Manufacturer-supported fit does not by itself establish filtration efficiency, odor removal or superiority over another replacement. Those performance claims need their own reviewed evidence for the exact filter and equipment combination.

These sources explain the fit, features and filter test results described above. They are not retailer price checks.
Installation and care
Caring for the filters
Nordic Pure suggests changing each filter every one to three months, depending on use and conditions. That is guidance for each installed filter, not a guaranteed life for the whole pack. No specific unopened shelf life has been established here.
