What are the advantages and disadvantages of reverse osmosis water purifiers and ultrafiltration water purifiers?

Both are common pure water equipment on the market. Both have their own advantages and disadvantages. Understanding their advantages and disadvantages is particularly important for choosing the right water purification equipment. Here I will briefly introduce their advantages and disadvantages. For reference.
1. Advantages

1. Reverse osmosis water purifier: The functions of reverse osmosis water purification equipment are more complete, integrating microfiltration, adsorption, ultrafiltration, reverse osmosis, ultraviolet sterilization, ultra purification and other technologies, which are fresher, more hygienic and safer.

2. Ultrafiltration water purifier: The produced water can be consumed directly; the effect is different according to the different filter elements selected. The ultrafiltration equipment adopts the new generation of filter elements in Korea, which has high filtration accuracy, long service life, water hammer, pressure resistance, etc. The tests have passed NSF test standards.

2. Disadvantages

1. Reverse osmosis water purifier: the effluent is pure water that can be directly drunk, the output is small, the ratio is about 4 to 1, the discharged wastewater is not drinkable

2. Ultrafiltration water purifier: The effluent ratio of the ultrafiltration water purifier is 2 to 1, and the filtered water can be drunk directly, but the premise is normal tap water. After all, the ultrafiltration membrane is only a physical filter, which is not chemical. Substances cannot be filtered, so there is no problem with general tap water filtration. However, the taste of water after ultrafiltration membrane filtration is not as good as that of reverse osmosis membrane.

After understanding the advantages and disadvantages of the two, you can choose a suitable water purifier
