Filtrete 12x12x1 AC Furnace Air Filter, MERV 13, MPR 1900, Premium Allergen, Bacteria & Virus Filter, 3-Month Pleated 1-Inch Electrostatic Air Cleaning Filter, 2-Pack (Actual Size 11.81x11.81x0.78 in)

As long as you measured correctly, you’re ok.

These are great filters. They really help with reducing allergens. They fit the unit perfectly so easy in, easy out! They get a lot of the dust we get here every time you open a door. They also help filter out most of my mom's cigarette smoke before it gets to my room.Our apt complex replaces what they call filters monthly, free of charge but these are so good I don’t mind having to pay for them. I would be so miserable, especially in the mornings if it weren’t for these. I’ve used them for years everywhere I’ve lived.They are a little expensive but not my so bad I would sacrifice my health by not using them.

Reasonable price.

Good filters, good price

Change my filter every 3 monthsThese work great
