Review on Colorfullife Replacement Purifier Particle Activated by Tyler Bonnell

Have been buying them for a few years now and am very happy with the product. until now. The last delivery received on 04/22/2021 is SERIOUSLY inferior to the previous quality. The filter has a larger circumference and is attached too loosely to the plastic frame of the cleaner. The charcoal mesh looks where it used to be dense and opaque. The accordion paper folds are also twice as thin. I guarantee this latest CHEAP version does not meet the HEPA filter standards expected when using a 411 air purifier. I have SERIOUS allergies and COPD so I cannot compromise on filter quality. VERY disappointed to the point that I will again only buy replacement filters from reputable brands.
