Ultimate Guide: How to Choose the Right Water Filter for Your Home
Apr 08, 2017
Are you all set to buy a new filter system for your house? We urge you to stop and think for a moment about it. You may have your mind set on a particularly known brand, but you need to consider a few important points before you decide.
While you can opt to get bottled water from the market, it’s always safe and convenient to filter your water. You know where your water is coming from and you can safely store it in clean containers rather than toxic plastic bottles that are laced with various chemicals.
So, what do you look for in a water filter? There are so many kinds of filters in the market and it’s sure to confuse you. That’s why we have a 4-step solution for you. Follow these steps before you purchase a water filter system for your home.
1) Identify your needs
Before you choose a filtration system, you need to know what’s in your water and what particles you need to get rid of. From the water utility department get a copy of your area's annual water quality report. You can also use an at-home test kit to find out what’s in your tap water. If none of these options holds good for you, you can send a sample of your tap water to any local lab and get the report.
2) What kind of filter do you need?
Based on the quality of water in your area, figure out what type of filter you need. Activated carbon filters are the most common types of filter. They can remove heavy metals like copper, mercury and lead, parasites, chlorine and pesticides. If there are other contaminants in the tap water then it must be removed using a different type of purification system.Some chemicals in the water can be removed only by reverse osmosis (RO) purifiers and arsenic must be removed through distillation.Make sure that you’re purchasing a filter that can target the harmful contaminants in water.
Here’s how the filters work:
Carbon filter: You can find activated carbon in pour-through water filtration pitchers and many under sink filtration systems. Carbon filters trap contaminants in the pores of the positively charged, highly absorbent filter.
Reverse osmosis (RO): RO purifiers reverse the natural flow of water, passing it through a semi-permeable membrane. It is one of the most effective purifiers.
Distillation: Distillers heat your tap water to the boiling point, then collect the steam as it condenses, leaving contaminants behind. But they’re not a very good option if you have chemicals in water.
3) Location of your filter
You can choose either a whole-house filter, which will filter the water before it enters your home or a point-of-use filter, which will filter the water just before you use it. There are different kinds of filters depending on the type of installation such as table top, wall mounting and under the. sink. But before you choose any of these purifiers, make sure that you are aware of the TDS levels of the water in your area. TDS levels vary from area to area and also depends on the source of water. If the TDS levels are low (0-200), your water is soft and clear and you can use a UV or basic RO purifier. If TDS levels are moderate (200-500), water will usually have a salty taste which requires an RO with additional features to get rid of the saltiness. If the TDS levels are high (more than 500), you’ll need an RO with superior features to get rid of the hardness and bad taste.
Whole-house models just remove mineral deposits and unpleasant odours or tastes.You’d still need to supplement a whole-house filter with another type of filter to remove harmful contaminants. Point-of-use filters are more effective in that case. Find a filter with an activated carbon filter or an RO purifier, if you’re looking for a permanent solution.
4) Find an ISI certified filter
Always purchase a filter that’s ISI certified. It means the filtration system has been tested to ensure it actually removes the contaminants it claims to remove. Most companies are certified but their products aren’t. Don’t purchase products that are not certified.
Now that you know what to look for in a water filter, you can make an informed choice. Make sure you choose a reputed brand and certification of the product before purchase. You should have the filter installed by professionals only. Wait no more, give yourself the gift of pure water today!
