We’ve tested hundreds of filters—and here’s what we found: high-quality air filtration doesn’t have to come at a premium. According to data from IndoorAirCenter.com, most homeowners overpay by up to 40% for name-brand filters that offer no measurable improvement in particle capture or airflow. That’s why we created the 11.25×23.25×1 Filter Bundle—a smart, budget-friendly solution engineered to deliver lab-grade filtration at a homeowner-friendly price. Built with the same high-density pleats and durable frames we use in our pro-grade filters, this bundle gives you everything you need to protect your HVAC system and breathe easier—without compromising on clean air or cost.

Frequently Asked Questions
What does a 11.25×23.25×1 air filter fit into?
This size is commonly used in residential HVAC systems that require a non-standard filter dimension. It’s best to double-check your existing filter or HVAC manual to confirm compatibility, as our filters are manufactured to be true-to-size for a precise and efficient fit.
How often should I replace these filters?
In a typical household, replacing your filter every 90 days is ideal. However, if you have pets, suffer from allergies, or live in a high-dust or pollen area, changing the filter every 30 to 60 days will help maintain optimal air quality and system performance.
What’s the difference between MERV 8, 11, and 13?
MERV 8 filters handle common particles like dust and pollen. MERV 11 filters go further by capturing pet dander, mold spores, and finer dust. MERV 13 filters offer the highest protection by trapping bacteria, smoke particles, and virus-carrying aerosols—ideal for allergy-sensitive homes.
Will using this bundle save me money?
Yes, it will. Buying in bulk reduces the cost per filter, and regularly replacing filters helps your HVAC system run more efficiently—potentially lowering your energy bill by up to 10%, according to EPA research.
Are Filterbuy filters made in the USA?
Yes, all Filterbuy filters are proudly made in the USA using durable, high-performance materials, and they’re rigorously tested to meet or exceed industry standards.
