Tankless vs Tank How to Choose a Reverse Osmosis Water Purifier?

There are two types of reverse osmosis water purifiers on the market today, namely a tank reverse osmosis water purifier and a tankless reverse osmosis water purifier. Faced with these two types of reverse osmosis water purifiers, I believe everyone will be confused when choosing. So how do you choose between these two types of reverse osmosis water purifiers?

The difference between tank reverse osmosis water purifier and a tankless reverse osmosis water purifier

There is a tank reverse osmosis water purifier with a pressure tank, which is mainly used in closed water circulation to balance the water volume and pressure. The existence of the pressure tank can avoid the frequent opening of the safety valve and the frequent replenishment of the automatic water replenishment valve, extending the service life of the water purifier. In addition, the pressure tank can also solve the pure water supply when the user's home is stopped.

The tankless reverse osmosis water purifier does not have a pressure tank, which releases the space under the kitchen, and solves the pain point of slow water production with tank reverse osmosis water purifiers, realizes instant filtering and drinking, and solves the possibility of secondary pollution in the pressure barrel Hidden problems.

Comparison of the advantages and disadvantages of tank and tankless reverse osmosis water purifiers

Occupied Space

Area with tank VS Area with tankless reverse osmosis water purifiers

Compared with the tankless reverse osmosis water purifier, the tank reverse osmosis water purifier has an extra pressure barrel, so in terms of floor space, the tank reverse osmosis water purifier will be larger than the tankless reverse osmosis water purifier.

Noise Level

With tank noise VS Tankless reverse osmosis water purifier noise

Reverse osmosis water purification technology requires a water pump to make water. Some tank machines have pressure barrels. After a full tank of water is made, the water purifier will stop working. The machine will not start to make water until there is almost no water in the tank. Water, so the requirements for the power of the pump are not high. The reverse osmosis membrane used in the tankless machine is above 400G. Therefore, the power of the pump is correspondingly larger. The greater the power of the pump, the greater the noise. This is why some tanks of tankless machine shells are pasted with a thick layer. The reason for the sound insulation cotton.

Water Speed

Water outlet with tank VS Water outlet without tank

There are tank machines because the prepared water is stored in a pressure barrel in advance, and the water in the pressure tank  can quickly come out when drinking. Although the Tankless reverse osmosis water purifier produces water faster than the tank machine, no matter how fast it is, it is faster than the tank machine. Because the tankless machine is instant filter and drink, it has to pass five filtration levels at one time, while the barrel machine only needs to pass one filtration level. Relatively speaking, the water output speed of the barrel machine is better than the water output speed of the tankless RO system.

Failure Rate

Failure rate of machine with tank VS failure rate of machine without tank

The tankless RO system can start the machine as long as the faucet is turned on, and the frequent start of the machine will accelerate the aging of internal electrical components. In addition, the working current of the tankless RO system is 3-4 times larger than that of the tankless machine. The working frequency of the pressure switch contacts of the machine is quite high. For this reason, the probability of failure has also become greater. Because the tank machine does not need to be started frequently, and the working current is small and stable, the failure rate is relatively low.

Hygiene Issue

Tank RO system VS Tankless RO system

The pressure tank with RO system is a closed structure, if it is used for a long time without replacing it, it will easily induce secondary pollution. Since the tankless machine does not have a pressure tank, there is no need to worry about whether the pressure tank will produce secondary pollution. Of course, as long as the pressure tank is maintained well, the problem of secondary pollution of the pressure tank can be avoided, because the pressure tank is in a vacuum state, in this state, bacteria cannot survive.

Price

Tank reverse osmosis water purifier price VS Tankless reverse osmosis water purifier price

The price of the tankless machine is more expensive than the price of the barrel machine. Because the tankless machine needs to filter and drink immediately, and it is frequently turned on, the material used for the tankless machine is better than that of the tankless reverse osmosis water purifier. In addition, in terms of the cost of replacing the filter element, the tankless machine is more expensive than the barreled machine, because the reverse osmosis membrane of the tankless machine will be larger than the barreled machine, which is why the tankless reverse osmosis water purifier is faster than the barreled machine.
