Title: TruFilter vs. Standard Filters: MERV 11 tested… Allergen Defense payoff! We switched to the BNX TruFilter 12x12x1 MERV 11 (6-Pack) and noticed a difference almost immediately. The electrostatic pleated design traps fine particles like pet dander and smoke, while the MPR 1200 FPR 7 rating keeps things running efficiently. Unlike cheap standard filters, our HVAC system runs quieter, and our allergies feel less triggered. The MADE IN USA pride adds a bonus— quality we trust. Six filters last us an entire year, saving us time and hassle. True, they’re pricier than off-the-shelf options, but the Allergen Defense payoff is worth it. Our home feels cleaner, and our lungs thank us each time we breathe. The BNX filters stand up to the test—this is one upgrade we recommend without reservation.
