Ultimate Buyer’s Guide

drinking water filter system

Are you sure about the quality of water that you and your family are drinking? Unfortunately, there are so many hazards that are threats to our drinking water, including lead, pesticides, bacteria, and viruses. These are not only impacting cities but also well water sources. This is why you need to make sure that the water you drink is always clean and pure.

Although some people may resort to simply buying bottled water, this is not the practical way to go since the cost tends to add up. Even if a bottle appears to be cheap, in the long run, you may notice the massive expenses you accumulate in a year. So, the best way to do it is by investing in a good quality water filter system as a permanent and practical solution to having constant access to fresh drinking water.

Keep in mind that a water filter’s effectiveness largely depends on its ability to remove particular contaminants by using a certain technology. When it comes to removing inorganic substances, including minerals, asbestos, salts, and metals, a Reverse Osmosis water filtration system is the right choice for this purpose.

This unit usually comes with carbon pre-filters, as well as post-filters, that can capture sediment, radon, THMs, and herbicides. The filter can also get rid of lead, but others fail to eliminate chlorine completely. Some models advertise to do so, but you may want to request proof of performance to back such claims.

drinking water filter system

If you are planning on buying a reverse osmosis filter, then here are some things to look into to ensure your satisfaction from your purchase.

Large Capacity

While a pitcher water filter may be cheap, it has a limited capacity that makes it less ideal for a large family. You want to have a constant supply of pure drinking water, and buying a very large pitcher may not even fit in the refrigerator. This is why a faucet-mounted, under-sink, or countertop water filter may be a better choice considering the convenience they give you in providing quality water to drink anytime you want.

Flow Rate

There are some water filters with a very slow flow rate, while others have a moderate flow rate. If you opt for the latter, you can get gallons of water without a long wait. But you have to realize that over time, some filtration units slow down their flow rate when it is nearing the end of their lifespan. You can always change the filter to solve this issue.

Filtering Components

A  number of water filter systems make use of carbon to absorb all impurities and odor each time water passes through this material. As a multi-stage filter, this can eliminate contaminants, with the semi-permeable membranes of RO systems capable of flushing massive amounts of pollutants.

Indicators for Filter Change

You need to know when exactly is the right time for you to change the filter, so you can maintain the excellent operation of the unit. Thus, go for a water filter that comes with an indicator to help you determine when the filter must be changed. Some units come with stickers or timers to remind you once the third or sixth month has passed.


All manufacturers test their water filter systems, but you need to take it to the next level and require an actual certification as proof to back up such claims. Go for water filtration units that are certified by the Water Quality Association (WQA) or NSF International. These independent and highly recognized organizations have reliable databases that allow consumers to search for the model’s overall quality and effectiveness.

Additional Tips to Know

Be sure to identify the contaminants that affect the water you drink. Some water sources are more prone to heavy metal and chlorine, while others have other issues. This is why contacting your local water supplier can help in providing you with information, as well as coordinating with a water tester who is state-certified. By doing so, you can determine which water filter you need according to the types of contaminants or issues concerning your water sources.

We hope that we were able to help you choose the best water filter system for your needs. Be sure to check each item carefully and base your decisions once you have your water tested to achieve total satisfaction with your purchase.
