### ⭐⭐⭐⭐⭐ Review
*by C***I on 16 May 2025*

Updated Nov 11, 2025 After one year, we still haven't gotten the warning to change filter. We are two persons+2 cats with 3.6L/123oz of water fountain tank that needs to be changed every 10 - 15 days and I also cook and drink a lot. The machine still works perfectly fine. There's no leakage or malfunction occurred at all. Couldn't recommend this enough! ------------ Old review Background before buying APEC I'm familiar with RO water and prefer it over anything else. I also used RO filter in Thailand and when I moved to USA I thought the water quality would be better so I wasn't looking for RO filter. I used tap water for cooking and drinking by filtering with Brita before but I personally hated it because there's still chlorine smell and honestly you can't trust water quality these days because there's a lot of contamination in it so Ineeded better filtration. Water quality It's RO so quality is as good as the bottled water. No chlorine smell. Water has taste but it has no sharp feeling when drinking. If you're worried that RO will get rid of minerals in the water, to be honest, you can get minerals from somewhere else - cooking, supplemental pills etc. Having access to non contaminated water is my priority. Filtration system When you use up one cycle it takes 90 seconds to filter new cycle in it. It doesn't take long at all. The noise can be high but it never really bothers me as it's a quick process. The vdo I attached is of when it's filtering new tank. Suitable for 2 people with small animals. We are a couple and have 2 cats with big tank of water fountain. I also cook a lot. Bigger household should consider under the sink installation instead. We use tap water, it's NOT suitable for well water. Design is modern with decent materials. It's convenient especially those living in an apartment where you're not allowed to drill.
