Both Espring and 3M APDWS1000 are tested and verified by NSF with standard 42 & 53 with norminal particulate class I. Both of these filters are good and proven to be safe to direct drink by NSF without affecting our health. If you think 0.4% makes a big difference, how bout comparing things like VOC, chlorine & Nominal Particulate Class I, ≥0.5 to < 1.0 μm reduction.

I would agree that espring has better disinfection system with the UV light. However, as what stevie said, our water contains chlorine and there is not much harmful bacteria left for the UV light to kill. If there are family members or friends who are too weak, you can just boil the water. If you are not comfortable with the small percentage of bacteria and has extra budget then ofcoz u can go for espring. Once again, 3M has been tested by NSF to be able to filter off harmful contaminants and it is safe to direct drink.

I wouldnt say 3M is the best water filter but just saying that their package could provide a wider range of filtration (providing clean water rated 5 micron for whole house and clean drinking water which is safe to direct drink). So, what is good for your family is for you guys to decide.

If you are looking for something good yet affordable, 3M AP Easy Complete would be suitable. YOu do not have to worry about after sales service as we will follow up and assist you if you need to claim warranty and etc. 3M is a reputable company and we (Builders Hardware) is very reputable in lowyat forum for good price and service. With the 3M & Builders Hardware reputation, the certifications from NSF and healthy forumers who are still alive after using 3M (NIckLJF), what else can go wrong?

U can check the dealers online in 3M website or u can purchase from me. It is very ez to replace the cartridge, no need tools. Wont take more than 15 sec to replace the cartridge. The stock will only come in these few days, so i cant show u the video
