Okay, so I’ve been through SO many air filters, and let me tell you—these Aerostar MERV 13 ones? *Chef’s kiss*. First off, the fit is perfect (20x22x1, but actual size is slightly smaller—no biggie). Slid right into my HVAC like it was made for it.

The MERV 13 rating is no joke. My allergies have been brutal this year, but since switching to these, I swear my sneezing fits have dropped by like 80%. Pet dander? Pollen? Dust mites? This thing traps them all. Plus, the airflow doesn’t feel restricted at all—my AC isn’t working overtime.

Also, huge shoutout for being cost-effective. A 6-pack lasts me months (I change them every 60 days), and at this price? Way better than the overhyped brands I used to buy. The pleats are sturdy, no bending during install, and they actually *catch* dust instead of just looking fancy.

Bonus: My air quality monitor shows a noticeable drop in particulates after running the furnace fan. Wood stove smoke used to linger—now it’s gone in minutes. If you’re on the fence, just try them. Trust me.
