Frequently Asked Questions

Is reverse osmosis effective?

A reverse osmosis system is an effective way to filter the water source in your house, including refrigerators. It can be used in tap water from your faucet or in your refrigerator if you want a cold glass of water that is clean and safe to drink.

Does reverse osmosis filter out the water contaminants?

The water filtration system uses reverse osmosis functions by filtering out impurities and other contaminants present from your water source. The best thing about these reverse osmosis refrigerator kits is that they offer a more intense water filtration process than the regular fridge filter.

Can you connect a reverse osmosis refrigerator kit to an ice maker?

Yes, you can connect a reverse osmosis kit to your ice maker. To do this, all you have to do is to add extra storage for a water tank to make sure that it operates appropriately without running out dry. You can have crystal clear ice cubes in no time by doing this.

What is the water pressure needed for a reverse osmosis refrigerator kit?

The recommended water pressure for your kit is 30 PSI. Ensure that the water pressure is not too low or too high as it can affect the performance of your reverse osmosis refrigerator kit. 

How often should I check-up and clean my water filtration system?

It usually depends on your water source. If your water source is rich in sediments, debris, and other water pollutants, you might want to check on it every six months. However, if your water source is already safe, and there is little to no contaminants in it, you can clean out and replace the membranes used in the reverse osmosis refrigerator kit once every 3-4 years on average.
