Review on 🔍 BISSELL 2X Allergen Cleansing Formula: Effective Full Size Machine Solution, 60oz - 89Q5A by Barbara Ortega

I have never tried the "Professional" formula so I can't compare the two but I can tell you that this Allergan formula in our environment did very well. high-pile carpets and does without a strong fragrance. Our pets went into the rooms, which I cleaned as soon as we let them, and they stayed away if there was a trace of a strong odor. It seems to have helped my wife's pollen allergy and our nephew's pet allergy, however fairly frequent shampooing is required to maintain this protection (Bissell recommends once a month). I couldn't find this Allergan formula in my area so I'm glad Revain has it and the price of Revain seems very good compared to other types I've been able to find locally. Note, however, as at least one other reviewer has noted, pay close attention to the price of the different sizes. At the time of my purchase, 60 oz. The size was a bargain but 24 oz. There was no size as it cost almost the same as 60 ounces.
