Frequently Asked Questions

Why does the box show a different size?

The Envirowise outer box incorrectly shows 22.7x20x4.7, but the actual filters inside are correctly sized at 22.7x20.7x4.7. Always check the filter itself, not the shipping box.

How difficult is the assembly?

Assembly takes 1-2 minutes per filter. However, customers report challenges with sharp wire edges and securing tabs. Many prefer our pre-assembled compatible option to avoid these issues.

What's the difference between OEM and Compatible?

Both are 2-packs with MERV 11 filtration. The main difference: OEM ships flat and requires assembly (with potential sharp edges), while our compatible comes pre-assembled and ready to install. The compatible has 85+ 5-star reviews on Amazon.
