How To Choose The Best Inline Water Filter For Ice Maker

How To Choose The Best Inline Water Filter For Ice Maker

An ice filter must be competent to purify the water to the maximum possible level. There should not be any compromise or haste in choosing an inline water filter because it’s a matter of safe ice. These are some factors you must evaluate while buying the best inline water filter for an ice maker:

1. Filter Capacity

Filter capacity is an important deciding factor when buying an inline water filter. The capacity means how many gallons or liters of water the filter can treat in one cycle.

Your daily usage and family size as well as requirements will determine the capacity of the inline water filter you need.

If you have a joint family with kids and more youth members, invest in a high-capacity filter because the total daily water consumption will be

Whereas, a nuclear family can manage with a low to medium-capacity inline filter.

Also, if you are buying an inline filter for commercial use in icemakers, make sure to go for high-capacity water filters.

Inline water filters have capacities ranging from 500 gallons to 20000 gallons.

2. Filter Size

The inline water filters come in many shapes and sizes for adjusting in different spaces. Usually, there are three sizes- small medium, and large.

Size is important so that the inline water filter can be installed in a compact space. Smaller inline filters are more portable. You can carry them on road trips or camping. Moreover, an optimum-sized inline water filter will make installation and replacement much simpler. Extra-large filters can compete for space and hinder day-to-day activities.

3. Water Type

The type of water supplied to your home matters a lot when deciding on the inline water filter. You see water filters also have different mediums through which they remove impurities. The category and density of toxins in water decide which mechanism will be required to deal with them.

The first step is to get your water tested by a professional to know its state. You can even conduct a home water test through a DIY kit.

If you reside in rural areas, you will get sulfuric water high in biotoxins, nitrates, arsenic, chemical pesticide residue, etc.

Whereas urban or city water is loaded with chlorine. It is bad for the skin and hair. Chlorine smell and taste can pass on to drinking water and ice cubes.

City inhabitants also get hard water with heavy metal composition.

Consider buying a charcoal or carbon-activated inline water filter to get rid of chlorine, volatile organic compounds pesticides, fluoride, and other contaminants.

Whereas, a special hard water inline filter is required to remove minerals like calcium, magnesium, and lead. It uses Kinetic Degradation Fluxion for effective filtration.

4. Filter’s Ease of Installation

A hassle-free installation saves time and allows smooth functioning. Inline water filters should not require too many tools or effort for installation. For this, you need to check the compatibility of your ice maker machine or refrigerator with an inline water filter by measuring the water line diameter. Inline water filters are fitted securely on the water line, therefore it’s necessary to match their size.

Most inline water filters come with a DIY installation kit that has step by step guide for mounting and attaching the filter following a simple procedure.

Try to choose cartridge system filters where you permanently fix a head unit at the initial place of installation. After that, Cartridges are easy to replace with just a twist and pull motion.

5. Filter Replacement Time

Filters get dirty with the accumulation of dirt, dust, minerals, sediments, and other substances. They need timely replacement to continue working in the best quality.

Some filters need replacement periodically after every 6 months while other companies boast their inline filter can work without replacement for 3 to 5 years. Ask your retailer for more information based on past customer reviews and buying patterns.

If your area has a high contamination level in the water, you are likely to change cartridges of the filter more often as impurities settle quickly in large amounts.

6. Micron Rating

The Micron Rating of the inline water filter is directly proportional to the level of water purity. Micron rating means how precisely your filter can filter out small contaminants. It measures which size of particles pass through the filter and which are blocked. Micron ratings range between 5 to 25. Filter with a 25-micron rating does not trap sediments. They are ideal for clearing out chlorine smell. A 5-micron rating filter will clear out all minute toxins like dust, mineral, metals, and more.

7. Certification

Certifications affirm the standard of inline water filters. Different industry regulators and parameters are used to certify filters in many aspects. Inline filters backed by certification perform better as their features are more genuine. Therefore, buy an inline water filter with at least one certification. Some trustworthy certifications are provided by NSF, ANSI, and WQA.

8. Warranty

The warranty protects your investment in the inline water filter. It gives peace of mind and does not make an extra hole in your pocket. Although inline water filters are reasonably priced, it does not hurt to have a warranty.

You can claim free part replacements and repair if your inline water filter breaks or malfunctions due to unexpected circumstances. A product in a warranty period is eligible for availing company-borne inspection services. There can be a limited warranty or a lifetime warranty.
