High quality

[This review was collected as part of a promotion.] I received a Filtrete™ Refillable MPR 1550 Allergen, Bacteria & Virus Air Filter Kit (4") from Influenster for my honest review. The filtrate system feels and looks high-quality. It assembled easily and the kit came with a spare filter, resulting in 12 months of filtering before another replacement is needed. Once assembled, the product slid easily into my system and provided clean breathable air. #influenster
