Just got my hands on the Aerostar 16x21 MERV 8 air filters, and wow – what a difference! The 6-pack is super convenient, and I love that they're made in the USA.

Installation was a breeze – the arrows make it foolproof. No more guessing which way the filter goes in! The pleated design looks sturdy and seems to catch way more dust than my old cheap filters.

I've noticed my allergies acting up less since using these. That MERV 8 rating really works – fewer sneezes and clearer breathing. My HVAC system seems happier too, with good airflow and no weird noises.

The only tiny downside? They fit maybe a millimeter too snug in my unit, but nothing a gentle push can't fix. For the price and performance, I'll definitely be buying these again!

Pro tip: Set a calendar reminder to change them every 2 months – they work best when fresh!
