Common Questions About the Aprilaire 413 Clean Air MERV 13 Replacement Filter
How often do you change an Aprilaire 413 filter?
Aprilaire specifies once per year under standard residential operating conditions. Homes with 3+ dogs or heavy renovation dust may benefit from a 9-month interval.
What is the difference between Aprilaire 410 and 413?
The 410 is rated MERV 11, while the 413 is rated MERV 13. Both fit the exact same cabinet, but the 413 captures significantly more fine smoke, smog, and virus carriers.
Does the 413 require pleat spacers?
No. The 413 uses modern Self-Seal interlocking rails; old wire pleat spacers from legacy Space-Gard cabinets are no longer needed.
