Cons
- Requires an Aprilaire media cabinet

Consensus
Compare
Ranked #4 based on expert reviews, user sentiment, and value analysis.
Pros
- Huge size catalog including customs
- MERV 13 at value pricing
- Subscription discounts
Cons
- 1-inch MERV 13 raises static pressure

- OEM cabinet sealing
Cons
- Only fits 4-inch return cabinets
- MERV 11 trails newer 13-rated media
