Product review (2 stars): Slightly used?
Expected to receive a new filter without any white residue on it. It appeared to have been used and repackaged as new. I have not had it even 6 months yet and does not filter properly. Slimmey foul-smelling mold and mildew like substance develops quickly in base. Concerned of health problems occurring with my allergies.--the reason I needed a good filter. The Hunter unit is cleaned once to twice weekly with vinegar as recommended and still have problems with this slim and also calcium build up. Please send a (NEW) replacement.
