we discussed this before in some time ago. Checked alphamax website d, the model should b A0840 & A0845.
1) NSF 61 is mainly on components and not the performance of the filtration.

NSF/ANSI Standard 61 Drinking Water System Components - Health Effects is the standard that establishes minimum health effects requirements for materials, components, products, or systems that contact drinking water, drinking water treatment chemicals, or both.
2) The salesperson might tell you that you do not need to change anything but you will need to change the sand and microz averagely 3 years once.
Alphamax is OEM by Perfect Steel. Since they are the same, i cant c why Perfect Steel requires changing of sand while Alphamax do not need to change
anything. Have a look at below, i highlighted the spec for both filters, they even use the same wordings.
3) Cant comment much on the indoor water filter (AMAX-08T) as they didnt post the spec online. However, i doubt they have any NSF certificates on their performance. The filter look cheap and ugly.
If you are looking for a good sand filter and indoor combination. I would recommend
Perfect Steel G2 series (similar to Alphamax A1040, better than A0840 & A0845) + 3M AP Easy Complete = RM 1750 only with our Merdeka Promotion.
3M AP Easy complete has NSF standard 42 and 53, these two standards show that it can filter odor, chlorine and bad contaminants.

NSF/ANSI Standard 42: Drinking Water Treatment Units - Aesthetic Effects
Overview: This standard covers point-of-use (POU) and point-of-entry (POE) systems designed to reduce specific aesthetic or non-health-related contaminants (chlorine, taste and odor, and particulates) that may be present in public or private drinking water.
NSF/ANSI Standard 53: Drinking Water Treatment Units - Health Effects
Overview: Standard 53 addresses point-of-use (POU) and point-of-entry (POE) systems designed to reduce specific health-related contaminants, such as Cryptosporidium, Giardia, lead, volatile organic chemicals (VOCs), MTBE (methyl tertiary-butyl ether), that may be present in public or private drinking water.
However, for better filtration i would recommend 3M AP902 (POE filter) + 3M APDWS1000 (POD Filter)
