Genuine 3M product – well packed and received in perfect condition
Received the 3M Home Water Filtration replacement cartridges (IAC420) in excellent condition. The packaging was secure, and the cartridges appear to be 100% genuine 3M products. Fit perfectly in my existing system and arrived exactly as described. Very satisfied with the purchase and delivery quality.

Genuine Product
I am using this product for my 3M overall water tank filer. Its one of the best product from 3M and Original Product was delivered by AMAZON.

Too costly..
Does not last for long. It changes it’s white colour within a month and slowly turns pitch black in 3-4 months. Since it is very costly and every year you need atleast 3 replacements, running cost is very high, 10k per annum it is going to cost you. Either the price of the cartridges has to come down or quality has to improve so that it lasts longer. Even if it runs for 6-8 months, cost is manageable.

Awesome
Works great and as expected

Good but pricey
This prevents scale but dont know for how long, needed to change it after 3 months. The filter also catches a lot of iron which needs cleaning as this layers on the outer cover. Inside there are crystals and I managed to remove the cover and load resins to recycle and use it again. Also the price is quite high for a domestic use.

Doubt if it is genuine, doesn’t appear to be genuine
I can’t confirm if it is genuine product, I seriously suspect that it is not an original one. The package looked very old with a cello tap seal. There were no papers inside. The filter inside has no visible logo of 3M. I will think again before buying in future.
