Hi I am looking for water purifier recommendations

1. landed or condo? Condo
2. how many pax in your household? 1-2 pax
3. got senior / babies / people with disease like kidney failure for example in the house? No
4. can you able to do some small DIY installing yourself or not? (like replacement filter yourself?) Yes
5. how much u afford to installment per month for at least 5 years? 50/mth or 100/mth or 150/mth? ~100 month
6. or do u prefer 1-time off purchase? below 1k or 2k or 3k? Not really
7. do you own external water filter yet? No
8. hot/water function is it a must for you? will you willing to fork out another RM50/mth electricity bill for the feature? or you just stick with thermal pot + fridge cold water? Must have hot/cold, more emphasis on cold water, water needs to be super cold if possible. Not negotiable.

Basically just looking for tabletop water purifier/dispenser for cold water. Doesnt need to be super fancy as long can dispense cold water whenever I need it. Saw a few brands Cuckoo, Coway, SKMagic and LG but not sure which to get yet.
