5 Things To Consider When Buying Water Filter

Without water, life becomes impossible. However, the quality of the water people consume daily is deteriorating. Water filters are now required in every home to improve the quality of drinking water. However, people frequently make errors when it comes to purchasing water filters. They make mistakes when it comes to the filter’s methods, flow rate, and power.

If you’re considering getting a water filter for your home, you’ve landed in the right place. This article will discuss several critical factors to consider when buying this vital piece of home equipment.

1. Elimination Of Contaminants

Installing a water filtration device is primarily to remove pollutants from tap water and make the water potable. Water delivered to your home may contain various contaminants that are potentially hazardous to your health.

Impure water can introduce biological impurities into your body, including bacteria, cysts, and other microparasites. Several studies have demonstrated that household water may contain harmful chemical contaminants associated with increased cholesterol, obesity, and hormone suppression, among other health problems. Additionally, heavy metals such as arsenic and lead may be present in drinking water, increasing cancer risk.

To determine which filter is best for you, have your water tested in a certified laboratory to check for pollutants. The majority of filters remove between 40 – 60 pollutants, with some filters eliminating as many as 60 and others as few as 25. Consider purchasing a filter based on the laboratory results.

Another filtration system is activated carbon. Activated carbon filters can remove most organic compounds. They can reduce chlorine, Trihalomethanes (THMs), parasites, nitrates, sulfates, arsenic, and heavy metals via reverse osmosis (RO) or ultrafiltration (UF) systems.

2. Quality Of Water Supply

The source of water that you use dictates the majority of your filtration requirements. The first step is to determine the flow and consistency of the water supply. Simple checkup kits are available in the market or you can hire a specialist to perform the procedure for you. Water sources are classified into two categories:

  • Individual Or Private

Private water sources include bottled water, spring water, reservoirs, shallow wells, lakes, ponds, and river canals. You can make your own water source like rainwater harvesting, residential boreholes, and cisterns.

  • Public

Utilizing private water sources, such as a well or bottled water, is all good. But if your source is a river, a pond, or a stream located in a public property, ensuring water sanitation is quite time-consuming and costly. In turn, one would be hard-pressed to dig a well in one’s property. But such is not a dependable source of water: they can dry up in the summer. If you change your mind and decide to use a public water source, then installing a water filtration device at home is still critical.

3. Pressure

The filter should be purchased based on the flow rate of the running water. An RO device will function properly under high water pressure. However, the pressure depends on the home or building’s height. Clogged pipes and other filters also affect the water’s flow rate and pressure. 

Most water filters require pressures of 5 – 40 pounds per square inch (psi). If the water pressure in your home is insufficient, a booster pump may be used in conjunction with an RO system. On the other hand, if your water source contains fewer total dissolved solids (TDS), an activated carbon filter may be used.

4. Electricity

Electricity is critical when it comes to water filters. Many models are designed to run on electric power, making them suitable for home use. The UV filter is such. It requires electricity to generate ultraviolet radiation that kills bacteria. 

An RO system can’t work without electricity, as it’s required to create sufficient water pressure for the RO membrane to function correctly. Unlike sediment filters and ultra-filters, activated carbon filters do not require energy. 

Non-electric cleaners remove only a small percentage of contaminants in the water. They remove germs and sand, too. In contrast, RO and UV systems effectively remove TDS and bacteria that cause water-borne diseases. Electric water filters are the better option.

5. Future Maintenance Expenses

The cost of maintaining safe, drinkable water varies significantly according to the type of filter used. While most filters are inexpensive, the other option—cartridges, cost high. You also need to consider hose replacements which are not inexpensive. Therefore, before making a purchase, obtain a comprehensive service and repair quote from your water filter manufacturer.

Filters are not purchased once and then discarded. They require maintenance regularly. The question of how often depending on the cartridge’s quality. Numerous manufacturers include features such as a consistency index and cartridge replacement indicators. When filters are not changed regularly, water quality degrades, hoses clog, and power consumption increases.


These are just a few of the critical factors to consider when shopping for water filters. By following the guidelines outlined above, you can ensure that you get the water filter suited to your situation.
