TL;DR Quick Answers

17x22x4 Air Filters

A 17x22x4 air filter is a 4-inch deep, custom-size pleated filter built for HVAC systems and furnaces that don't fit a standard 1-inch slot. The extra depth means more pleated surface area, which traps more dust, pollen, and dander while putting less strain on your blower than a thinner filter would.

Here's what to know at a glance:

• Actual size: Filterbuy 17x22x4 filters measure slightly under nominal (typically ~16.5 x 21.5 x 3.75) for a snug, leak-free fit

• MERV options: MERV 8 (everyday dust), MERV 11 (allergies + pets), MERV 13 (hospital-grade, captures up to 98% of airborne particles)

• Replacement cycle: Every 6–12 months for a 4-inch filter — much longer than 1-inch versions

• Best for: Homes with deeper filter housings, allergy sufferers, pet owners, and anyone wanting fewer changes per year

• Made in the USA, shipped factory-direct, with auto-delivery so you never run out

If 17x22x4 is your size, you're already set up for one of the most efficient filter formats on the market — you just need to pick your MERV.
