Review on 🌬️ Enhanced True Blue Allergen 20X25X1 Filter: Unrivaled Protection for Clean, Allergy-Free Air by Erik Peterson

Thin, not in original packaging, only half an inch thick, not 1 inch as advertised. I also find it strange that True Blue filters supposedly do NOT use the MERV score for filtering. They use FPR as a measure. So I'm not sure why the box image of this product has a MERV 11 rating when the red box for this brand is a MERV 8. Be careful buyers, do your homework before you buy. This is especially important if you're buying them for a family member with allergies or asthma.
