OEM PART READY TO INSTALL WHEN SCHEDULED
They were hard to get for a while, but this was a new OEM part and is ready to install on schedule. I like the RO unit. These parts are expensive but very easy to install.

Aerosmith reverse osmosis water filters
Excellent water filtration

Great filter great tasting water.
This water filter worked perfectly. Made very “hard” very drinkable and coffee made through the whole AO Smith reverse osmosis process really tastes good.

Easy to install, change filter makes the water taster good worth the price of the filter very functional. Only have to change twice a year
User
Water produced good seems quite clean but installation not especially easy,
Installer reported poor design for water spigit and difficult installation for such even though he had the proper tools. He did call the company rep and reported the difficulty. One might also have wished for a stronger water flow from tank. Otherwise filters easy to exchange and water quality seems good. Additional filters for later exchange seem rather expensive.

Good filter
Very good

Convenient
easy to use, mine typically las a year because we have whole house sediment filter, Water softener, and city water. the price is very high on this, Convenient 30 seconds to install includes removing the old filter, opening the box removing all material and placing it in the filter slot. No need to shut off the water valve and no clean up.

Fits OEM, expected life not equal to cost
Fits fine, very expensive for its expected life compared to other brands. Why can't the manufacturer have a side alone website to buy?
