Product review (5 stars): GOOD PRICE, GOOD PRODUCT.
AMAZON HAD THE EXACT PRODUCT I NEEDED AT A GOOD PRICE, AND DELIVERED IT PROMPTLY.

NO RETAIL STORE IN NYC HAD THIS PRODUCT IN STOCK, AND EVEN THE BIONAIRE PEOPLE THEMSELVES WERE BACK ORDERED ON THESE FILTERS FOR THEIR OWN PRODUCT.  EVEN THOUGH A GENERIC PRODUCT ARRIVED, WITHOUT THE BIONAIRE NAME OF IT, THE FILTERS THEMSELVES FIT PERFECTLY IN THE BIONAIRE UNITS AND FUNCTION WELL.
