Hi Zheilwane, i am interested in 3M AP902 and Aquaphor crystal eco for indoor and outdoor. Please pm me the best price. Besides, i have a few questions to consult u:
1. Is AP902 suitable for landed house? i want to save space so trying not to go for those big sand filter.
2. For indoor water filter installation, would it be possible to drill a hole on concrete top (3.5 inches include tiles) for the water filter tap without breakage?
