Simply 20x20x1 Air Filter MERV 13 6 Pack - Allergy & Dust Control

Our review of the Simply 20x20x1 Air Filter MERV 13 6 Pack finds it best suited for households and small commercial spaces that need stronger filtration without complicated installation. The single biggest reason to consider these filters is the combination of MERV 13-level capture and a six-pack value, which makes them a practical option for allergy sufferers, pet owners, and anyone wanting to reduce dust, pollen and pet dander. They are universally compatible and easy to install, though some users report fit and sturdiness concerns under heavy HVAC loads.

Key Features

• Universally compatible size: The filters measure 20 x 20 x 1 in nominally and 19.75 x 19.75 x 0.75 in actual size so they slide into most central HVAC and furnace filter slots without modification.
• MERV 13 filtration: Rated to trap a high percentage of airborne particles including dust, pet dander, pollen and many allergens, improving indoor air quality for sensitive households.
• Advanced pleated design: A higher pleat count than many retail filters increases the capture surface and aims to balance particle capture with airflow efficiency.
• Up to 3 months life: Each filter is intended for about three months of use under normal conditions, which simplifies replacement scheduling for busy homes.
• Made in USA with recycled components: Constructed from 100% American components and recycled materials, offering local manufacturing and responsible material choices.
• Six-pack value: Supplied in a six pack to keep multiple changes on hand and reduce the frequency of reordering.

Who It's For

The Simply 20x20x1 MERV 13 filter is ideal for families with allergy or asthma concerns, pet households, and small offices where improved indoor air quality is a priority. Its six-pack format and roughly three-month replacement schedule suit owners who prefer to stock up and change filters seasonally or quarterly.

Those with very restrictive HVAC systems that require a thicker or manufacturer-specified filter should check system requirements first; similarly, buyers who need ultra-rigid construction or silent operation may want to consider sturdier, higher-end alternatives if noise or frame firmness is a top concern.

Pros & Cons

Replace approximately every three months under normal residential use, or sooner if the filter appears visibly dirty or if household conditions warrant more frequent changes.

Will these filters fit my unit?
They are nominally 20 x 20 x 1 in and measure 19.75 x 19.75 x 0.75 in actual, so they fit most standard 20 x 20 x 1 filter slots; always confirm your unit accepts MERV 13 filters before installing.

Do they reduce pet dander and pollen?
Yes, the MERV 13 rating and pleated construction are designed to capture dust, pet dander, pollen and many other airborne particles to improve indoor air quality.
