1. What is the filter level of this water filter system?

The UR02 countertop water filter is a 4-stage system with reverse osmosis filtration

2. Can this RO system produce hot water?

Yes

3. How is the waste water drained away?

It has a 7:1 pure-to-waste ratio, which is far superior to other products. There is no need to discharge wastewater.

4. Does the RO system filter out all harmful impurities?

Theoretical filtration accuracy up to 0.00o1 micron, can effectively intercept sediment, bacteria, heavy metals and other harmful substances in the water. Effectively remove residual chlorine and odor in water, improve the taste and make the water sweet.

5. Does this countertop water purifier need cleaning?

Yes, the machine can be cleaned by double-clicking the cleaning button. Please follow the instructions in detail.

1. What is the water pressure for this undersink RO water system?

The applicable inlet water pressure of this system is 0.1Mpa to 0.4Mpa. If the inlet water pressure exceeds 0.4MPa, it is necessary to purchase an additional pressure-reducing valve and install it before the water system.

2. What is the range of inlet water temperature for this Tankless RO System?

The water inlet temperature of this product is required to be within 41-100.4°F. This water system cannot filter hot water.

Even if you receive your water from a municipal treatment plant (city water), there's still a very high chance that sediment is in your water. That's why an inline water sediment filter is a good idea. If you're on city water, you might also consider installing a UV water filter to ensure all illness-causing microbes are removed from your water.

How often sediment filters are replaced depends on the quality of your water and the type of water filter system. But generally speaking, sediment filters should be replaced every three to six months.

Sediment filters are inexpensive yet provide excellent value. In fact, they usually pay for themselves within a short amount of time by protecting an expensive water softener, UV water sterilizer or other water treatment system.

Keep in mind that while a sediment filter can reduce sediment and decrease turbidity, sediment filters cannot remove heavy metals, chemicals or improve the taste and odor of water.
