True to size. Good quality at reaonsable price

True to size. Good combination of airflow and filtration. I am running them 600 runtime hours between replacements in a household with no pets and they could probably go 800 - but why chance it...

Great Subscription

Would Recommend

Lowes has made changing filters for me and my tenants a breeze. Tenants get prompted scheduled deliveries. The filters work great and the tenants report no issues with air quality. Review written without AI.

Great quality

I’m very happy with this air filter. It was easy to install, fit perfectly, and seems to do a great job keeping the air in our home cleaner and fresher. The quality is good, and I’ve noticed less dust since using it. It’s a great value for the price, and I would definitely purchase it again. Highly recommend!
