Filter King 14 x 20 x 2 MERV 8
This six-pack is best for households or businesses that use a nominal 14 x 20 x 2 filter and want multiple replacements on hand. Its listed actual size is 13.5 x 19.5 x 1.75 inches, an important distinction from the nominal size.

Filterbuy lists a MERV 8 synthetic media that captures dust, pollen, lint, and mold, and claims it captures 90% of dust without restricting airflow. The actual size is 13.5 x 19.5 x 1.75 inches. The listing recommends replacement every 90 days.

Buying Guide: How to Choose the Right Filter Size
Does 2 x 8 x 14 mean a 14 x 8 x 2 filter?
It may refer to a filter with a nominal 14 x 8 face and a two-inch depth, but confirm the order used by your equipment label or existing filter. Filter dimensions are often written in different sequences. None of the products in this list has a 14 x 8 nominal face.
Should you buy by nominal or actual dimensions?
Use the size printed on your existing filter as a starting point, then compare the product’s actual dimensions with the filter slot. For example, several Filterbuy products labeled as two inches deep have an actual depth of 1.75 inches. A nominal label alone does not confirm the correct fit.
What does MERV 8 tell you?
MERV 8 is the listed filtration rating for these products. The product descriptions identify common captured particles such as dust, pollen, lint, and mold. Check your HVAC manufacturer’s guidance when selecting a rating, and avoid assuming that a filter with the right rating will fit if its dimensions are wrong.
How often should you replace a filter?
Replacement schedules vary by product and home conditions. Filter King recommends a 30- to 90-day range, while the Filterbuy listings recommend replacement every 90 days. Follow the filter instructions and inspect it regularly, especially if your household has higher dust levels or frequent system use.
Frequently Asked Questions

Can a 14 x 20 x 2 filter replace a 14 x 8 x 2 filter?
No. The face dimensions differ. Choose a filter that matches the required slot dimensions rather than matching only the depth.
Are these filters all MERV 8?

What does “actual size” mean?
Actual size is the measured dimension of the filter itself. It can be smaller than its nominal size, so compare the actual measurement with your system’s requirements.
Which option is best for a 14 x 8 x 2 opening?
None of these products is identified as a 14 x 8 x 2 filter. Check the equipment manual or filter slot for the correct size before ordering.
