Frequently Asked Questions:
What is TriPure Technology?
TriPure is AprilAire's new filtration platform launching in September 2026, built around advanced purification media with up to 30% lower static pressure than leading competitors, up to 12 months of filter life, and self-aligning, toolless installation.
How is TriPure different from AprilAire's current 4" filters?
TriPure moves from 4" filters to a 3" filter format. The 4" filters will be discontinued as part of the transition. TriPure delivers lower static pressure (better airflow/energy efficiency), longer filter life (up to 12 months vs. shorter cycles today), and improved dust holding capacity.
Will my current cabinet still work?
Yes. Existing cabinets can be converted using the new Upgrade Kit, which includes preinstalled/compatible 3" rails plus a 3" filter. The kit offers backward compatibility with all AprilAire 6" cabinets, including legacy Space-Gard retrofit applications.
What's included in the Upgrade Kit?
A compatible upgrade rail and 3" filter packaged together for toolless, two-piece installation designed to minimize install errors and improve airflow.
How long does the 3" TriPure filter last?
Up to 12 months of filter life, aimed at reducing maintenance frequency and protecting HVAC equipment.
What performance improvements does TriPure offer?
- Up to 30% lower static pressure vs. at least one competitor's 4" brand (preliminary results, subject to change/legal approval)
- Superior airflow and lower resistance for energy efficiency
- Highest dust holding capacity in the market
- Premium protection against dust, particles, and common allergens
