Good, I think.
Pattern Name: 16x25x1, Style: Merv 11
Not my area of expertise but wanted something with a thicker filter and these seem to be doing well. They last 3+ months before discoloration is noticeable to the point you’d think it’s time to put in a new filter. The 6-pack price can’t be beat, truly. Easily installed and used, fits perfect to size and looks clean. Unknown relief on allergies so far since it’s been winter but I’m optimistic.

Better quality that name brand hardware store
Pattern Name: 20x20x1, Style: Merv 11
These are a great value for a multi-pack. They fit perfectly in the vent and you can definitely notice the difference in air quality. It’s much easier to just have a stack of these on hand so I can swap them out regularly without a trip to the store.

Great value filters – do the job well
Pattern Name: 12x12x1, Style: Merv 8
These filters are a great value for the price, especially getting a 6-pack. They fit perfectly (just keep in mind the actual size listed), and installation is quick and easy. I’ve been using them regularly and they do a solid job catching dust and keeping the air clean without restricting airflow. Good balance between filtration and performance. Nice to have multiple on hand so I can swap them out regularly without thinking about it. I’ll definitely keep buying these.

Most comfortable pillows for my back
I have a really bad back along with sciatica so I use these pillows on my recliner chair, one for my back and one under my bottom. They make all the difference in the world. They are soft and squishy yet still offer support. They are a great value for sure. This blue color was about half the price of other colors with was fine with me because I put washable covers on them anyway. I frequently fall asleep on them. My dog loves when they accidentally fall on the floor because he curls up on them and falls asleep. He finds them very comfortable. I can't say enough good about these. They would be great on a bed or couch too or even as a floor cushion. They are high quality, well made pillows.
