Buying Guide

An ice maker kit for reverse osmosis filters is many on the shopping websites. They all look pretty much the same and they all perform in pretty much similar ways, but what is it you need to look out for when shopping for a reverse osmosis ice maker kit to ensure your filtration system and ice maker produce the cleanest and clearest ice cubes? In this section, we’ll show you what to look out for.

1. Health and Safety

First, ensure that your reverse osmosis ice maker kit’s products and fittings are made from non-toxic materials. On the packaging, look for NSF markings: NSF (National Sanitation Foundation) certifies products that meet strict public health and safety standards. If an ice maker kit doesn’t carry the NSF markings and certifications, you can also search out for “Food-Grade” descriptions for the very minimum health and safety standards. You don’t want to go to all the trouble of purifying your water only for it to feed through sub-standard tubing into your refrigerator and ice maker to reduce the quality of your ice cubes.

2. Tubing Connections

The standard connection sizes for refrigerators and ice makers are ¼” and 3/8” tube diameters. Read your refrigerator or ice maker’s owner’s manual to check which size tubing is correct for you to fit.

3. Shut-Off Ball Valve

Your ice maker kit will come with a few connectors, tubing, and clips. What you should look for is a shut-off ball valve: this will prevent your refrigerator and ice maker from overflowing with water. Kits’ are made with plastic or brass fittings for durability and longevity.

4. Quick Connect Fittings

They manufacture most home reverse osmosis ice maker kits with DIY in mind. These kits can be fitted to your water filtration system and refrigerator without the use of tools.
