- Simply 12x12x1 Air Filter, MERV 8, 6 Pack, Furnace Air Filter for HVAC (Actual Size: 11.75"x11.75"x0.75") DUST, Pet, & Allergy Control

These MERV 8 filters are a great balance of quality and value. They trap dust, pet dander, and pollen really well, and I noticed less sneezing and fewer particles floating around within a couple of days of swapping them in. The actual size fits perfectly (19.75"x19.75"x0.75"), and the 6-pack makes it easy to stay on top of replacements without last-minute trips to the store. They’re durable, don’t sag, and airflow stays consistent — no strain on the HVAC system. If you have pets, allergies, or just want cleaner indoor air without spending a fortune, these are a solid choice.

The filters are sturdy and built well. I have been using a filter from big box retailers for several years but the price just keeps going up. The were half the price and equal or higher quality.

Exactly as advertised. Fit perfect. Good quality. Easy installation. Keeps the air quality in the house good.

I’ve been using the Simply 20x25x1 Air Filters for a while now, and I’m very pleased with the overall value. The Merv 8 rating is perfect for my home HVAC system, providing good filtration without being too restrictive. I typically change the filter twice a year—before winter and before summer—and these filters are always up to the job. At a great price for a 6-pack, they last a long time and keep my air quality consistent throughout the year. They fit easily into my AC and furnace units, and I’ve had no issues with poor airflow or compatibility. The MPR 600 rating is ideal for capturing common household particles like dust, pet dander, and pollen, so it’s a solid choice for families or anyone with allergies. Overall, these filters offer excellent value for the price, and I’ll continue to use them for my regular maintenance.

fit well and work well

I use these air filters and change them every 2 months. The filter quality is great. Also, a great price.

These filters came packaged well. Works perfectly and I love the quality of these filters. This is my second purchase and I will buy them again.

I recently switched to this Simply 6-pack because the prices for single filters at big-box hardware stores have become unreasonable. For the cost per unit, this set offers incredible value without cutting corners on quality. The actual dimensions (13.75" x 23.75") were spot-on for my intake vent. They slid in easily with a snug fit, preventing any whistling or air bypass. The cardboard frames are sturdy and hold their shape well, even when the system is running on high. As far as performance, the MERV 8 rating is the sweet spot for my home. We have a golden retriever, and these filters effectively trap dander and dust without restricting airflow or straining the HVAC motor like denser filters can.

Did the job they are intended for

Worked great for my older furnace with hard to find filters.

These are exactly what I was looking for, which has been very hard to locate at my local hardware stores. The 6 pack is nice too so I dont have to re-order very often

Didn’t quite fit what we needs for the furnace but my husband made it work. Happy with the quality and the job it does.

fit right in
