Buyer’s Guide

The following are some of the factors you should consider when buying a filter suitable for a large family.

1. Contaminants in Your Water

Have your water tested first; involve a reputable laboratory to carry out a water analysis.

Get to know the amount of TDS content in your water.

This way, they will be in a position to advise you on the best purifier and the purification technology to invest in for your filtration.

2. Filtration Rate

For a large family, go for a filter that has a high rate of filtration to ensure you don’t lack purified water on every tap in your house at any time.

Check on the packaging the level of pressure that the filter can hold. A low-pressure filter translates to a low water flow.

Also, review how many gallons per day the filter can produce; this will guide you on the best filter to buy.

3. Installation and Maintenance Cost

Go for a system that you can install yourself, and the maintenance cost is manageable. Filters that can last for 6 months are easy to maintain.

Let the filter you plan to buy have a way for you to tell when replacement is near. This way, you will have ample time to schedule and prepare for the operation.

4. Durability

You don’t want to be buying filters every other year. Let the filter you buy have a long lifeline. With proper maintenance, a filter should serve you for 2 years and above.

5. Space

As you plan on acquiring a filtration system, evaluate the space needed for your choice. For instance, most under-sink filters are bulky and could take up more space.

Evaluate the modifications you may need to make to accommodate it, including space for the extra faucet requirement.

6. Water Wastage

Let the filter you intend to buy conserve your water. Your water bills should not hike because of the choice of filter you make.

Incase minimal water will be lost, consider where you will direct the wastewater.

7. Essential Minerals

Your family still requires the essential minerals that the filter may have eliminated during filtration for your drinking water. Buy a filter that remineralizes your water.

8. Water Texture

I f you live in an area with hard water, consider acquiring a reverse osmosis filter that also works as a softener.

9. Certification

Go for a filter that has been certified by reputable bodies like the WQA and EPA. This way, you will rest assured the filter meets the quality standards.

10. Water Supply

Different water sources contain different contaminants. For instance, some filters work better on well water compared to others. Know your water source.
